Title: ADDICTIVE BEHAVIOUR


1
ADDICTIVE BEHAVIOUR
  • Dr.M.Clark

2
TOPIC A - THE CONSTRUCT OF ADDICTION
  • RECENT PAST predominance of medical model
  • 'ADDICT' - reserved for those who overindulged in
    certain behaviour, with associated loss of
    control, withdrawal symptoms and in whom a
    biological abnormality (disease) was suspected.
  • Most readily applied to substance abuse - notion
    of disease

3
BUT
  • With the rise of social-psychological models
  • Emphasis on biological element reduced
  • Cultural, social and psychological factors have
    important role to play
  • Addiction product of person- environment-activity
    interaction
  • Allows for inclusion of non substance based
    behaviours as addictions

4
Traditional concept of addiction highlights
  • Tolerance effects
  • Withdrawal symptoms
  • Relief from withdrawal symptoms on resumption of
    involvement
  • Emphasis on above factors criticised

5
alternatively
  • Addiction should be conceptualised in terms of
    the individuals attachment to the activity
    (Orford et al, 199648)
  • Frequency
  • Regularity
  • Quality
  • Preoccupation
  • Subjective feelings of being addicted
  • Harm caused
  • Difficulty in reducing or giving up the behaviour

6
Falling under the gamut of addictions
  • Chemical dependency
  • Gambling
  • Sex
  • Relationships
  • food
  • Work
  • shopping
  • Draw upon developments in the understanding and
    treatment of substance use to inform thinking and
    practice relating to non substance based
    addictions
  • Substance use often concurs with other types of
    addiction
  • Substitution

7
THE UNITY OF ADDICTIVE BEHAVIOUR
  • Dichotomy in the minds of many
  • Miller (1980) - where professionals would once
    speak of alcoholism or drug addiction now speak
    of 'addictive behaviours'
  • One common element, all involve 'some form of
    indulgence for short term pleasure or
    satisfaction at the expense of longer term
    adverse effects' (Miller, 19804)

8
Social stratification process at work
  • More readily label one form of behaviour as
    addiction than another
  • The case of alcohol - Weil, 1986)
  • Donovan (1988) evidence suggests a common
    foundation to all addictions, though final
    expression may be moulded by many different
    forces
  • Khantzian (1986) - similar evolutionary processes
  • Addicts use same defence mechanisms
  • Similarity in self help programmes

9
THE CONCEPT OF ADDICTION
  • The idea that addiction or addictiveness is a
    property of substances is loosing ground
  • Addiction is subject to cognitive and social
    processes rather than to purely biological ones
    (read extract from Peele)
  • Non substance based theories beginning to appear
    (e.g. Peele 2001 - addiction to an experience
    Brown, 1986 addiction as an active strategy to
    manipulate emotional well being Walters, 2001 -
    addiction as a lifestyle choice )
  • Consensus that addiction can be demonstrated
    where no substance is involved
  • Not disillusionment for the concept but
    recognition of its power and utility

10
Addiction as more than a physiological response
to drug use
  • Reluctance to widen understanding of addiction
    based on reluctance to formulate scientific
    concepts about behaviour that include
  • Subjective perception
  • Cultural values
  • Individual values
  • Notions of self control
  • Personality based differences

11
HISTORY OF THE WORD ADDICTION
  • Latin 'Addico' - giving over
  • 'addictus' - a person given over as a slave or
    creditor
  • Prior to 19th century rarely associated with
    drugs
  • 'a formal giving over or delivery by sentence of
    court. Hence a surrender or dedication of anyone
    to a master. The state of being addicted or
    given over to a habit or pursuit devotion'
    (Oxford English Dictionary, 1933)
  • Traditional meaning narrowed
  • Linked addiction tightly to drugs
  • Gave addiction an invariably harmful connotation
  • Identified addiction with the presence of
    withdrawal symptoms or tolerance
  • Resulting confusion excise the term from
    discussion of compulsive drug use e.g. DSM-IV
    eschews use of the term (dependence)

12
ATTEMPTING A DEFINITION!!!!
  • 'A behaviour pattern of compulsive substance
    abuse, relationships or other behaviours,
    characterised by over involvement with the
    relationship or abuse as well as a tendency to
    relapse after completion of withdrawal' (Freeman,
    1992)
  • Compatible with the bio psychosocial model - the
    subjective compulsion to continue behaviour
    pattern
  • Emphasis is on the process rather than on the
    substance
  • 'pattern' refers to symptomatology
  • addiction may be to a behaviour as well as a
    substance
  • tendency to evaluate behaviour with loss of
    control but can only be inferred
  • still no gold standard (Shaffer, 1999)

13
Criterion clusters of
  • progression
  • preoccupation
  • perceived loss of control
  • negative long term consequences
  • BUT
  • Walters (1999) objects proposing an alternative
    concept emphasising personal choice
  • Problem with Walters' conceptualisation -
    punitive
  • Advantage - personal responsibility for recovery

14
RESOLUTION
  • addiction must not be seen in terms of rigid
    dichotomies
  • points along a continuum
  • progression is NOT inevitable
  • those who present for treatment and often the
    sample in research studies are at the end of the
    continuum

15
Four main components
  • compulsion - desire
  • dependence - need
  • regularity - consistent
  • destructiveness - varied degrees
  • Hardiman (2000) combines the four elements
  • 'a condition whereby an individual regularly
    takes a substance, or acts in a particular way,
    in response to a strong and sometimes
    overwhelming desire to do so and that, in the
    absence of doing so, he will experience negative
    feelings or actual illness. By taking the
    substance or carrying out the behaviour the
    addict causes harm to himself or others'
  • not simply irresponsible people (moral model)
  • responding to very strong driving force
  • Alexander Schweighofer (1988) difference
    between positive and negative addictions
    (centripetal/integrative vs. centrifugal

16
CRITICISM OF THE CONCEPT OF ADDICTION
  • 'The addiction concept may well be the
    Frankenstein monster of modern American life'
    (Walters, 19991)
  • has been overstretched
  • relieve responsibility
  • criticism of positivism generally - return to
    classical thought
  • addiction is a nebulous concept
  • operationality of terms is a necessary
    prerequisite for the development of research
    agenda

17
MODELS OF ADDICTION
  • MORAL MODEL
  • ADDICTION A BIOLOGICAL CONSTRUCT (MEDICAL MODEL)
  • ADDICTION AS A PSYCHOLOGICAL CONSRTUCT
  • ADDICTION AS A SOCIOLOGICAL CONSTRUCT
  • Addiction to a experience

18
Why examine explanations for why people become
addicted?
  • Explanations have different implications for
    dealing with person manifesting addictive
    behaviour
  • Values and beliefs
  • All explanations have some validity
  • Fervour inflexibility controversy

19
MORAL MODEL
  • Addiction as a consequence of personal choice
  • Morally weak - lack proper will power
  • Adopted by religious groups and legal system
  • Based on classical thought
  • Important implications for what happens to people
    with addictive problems

20
BIOLOGICAL CONSTRUCT
  • Gained popular acceptance after Jellenik's text
    (1960)
  • Implicit component of AA and NA programs
  • Guiding model for many treatment programs
  • Viewed as a primary disease
  • Progressive
  • Irreversible
  • Complete abstinence
  • Abuse liability

21
TWO MAIN THEORIES
  • 1. Genetic theory
  • Genetic make up impacts the processing of a
    substance and/or the dose required to produce an
    ASC
  • Genotypes associated with addictive behaviour
    have been studied using three primary methods
    family studiestwin studies adoption studies
  • children of alcoholics children have patterns of
    alcohol consumption similar to natural parents
  • 30 to 40 of COA become alcoholics versus about
    10 of general population
  • alcoholism and the DRD2 gene
  • Blum et al (1990) - identified a mutant allele
    (A1) of the D2 dopamine receptor(DRD2) in
    chromosome 11 to be three and a half times more
    prevalent in 35 patients, examined post mortem,
    who during lifetime had abused alcohol compared
    to the post-mortem results of 35 non alcohol
    abusers
  • Various criticisms e.g. the A1 allele may be an
    effect rather than a cause of alcohol abuse
  • Predisposition vs. cause (alcohol has less effect
    drink more more problems)

22
Metabolic imbalance
  • Specifically applied to narcotic addiction
  • Dole Nyswander (19 ) certain addicts have a
    disease similar in action to diabetes
  • Once take narcotic body develops a 'craving' like
    diabetics crave insulin
  • No cure maintenance
  • Some addicts behave 'as if' this were the case
  • Physiological protection against addiction - the
    Oriental Flush

23
cont
  • Genetic components to this behaviour that put
    people at risk for future addictive involvement
    (Milam and Ketchan, 1983) e.g. DRD2 gene
  • Physiological correlates - e.g. gambling - nor
    epinephrine is elevated and serotonin reduced in
    some problem gamblers
  • Impossible to tell whether biochemical
    abnormalities are
  • A cause of problem gambling
  • An effect of problem gambling
  • Consequence of some third variable

24
Advantages
  • Removes moral stigma
  • Emphasis on treatment of illness
  • Makes it easier for people to enter treatment

25
disadvantages
  • No inevitable and completely predictable
    progression of symptoms and stages
  • No consistent lack of control
  • Individuals may not fit the model
  • May result in purely medical mode of treatment
  • not really applicable to behavioural or activity
    addictions
  • removal of responsibility
  • sick role - promotes unnecessary treatment and
    hospitalisation
  • Walters (1999) the simplicity of the model, once
    considered to be its strength - is now
    considered to be its weakness

26
cont
  • Thomas Szasz (1987) - products of
    neurophysiological discharges become behaviour
    when they are organised through intent
  • 'Although simplicity clearly facilitates
    understanding, the summarisation of highly
    complex behaviours like those observed in the use
    of cocaine, the preoccupation with sex, or the
    binge-purge cycle of bulimia, may result in a
    superficiality of understanding'

27
ADDICTION AS A PSYCHOLOGICAL CONSTRUCT
  • Focuses on internalised processes
  • 5 main constructions
  • the self medication hypothesis
  • addiction as a component of the obsessive
    compulsive spectrum
  • addiction as a personality construct
  • addiction as learnt behaviour
  • Problem behaviour proneness

28
self medication hypothesis
  • ego deficit marks addictive behaviour
  • roots in psychoanalytic theory
  • addictive behaviour is engaged in to alleviate
    psychiatric symptoms and painful emotional states
  • Criticisms
  • anxiety and psychological distress play an
    important role in maintaining the addiction
  • reduction in negative effect has minimal effect
    on drug use
  • alleviation of drug use problems positive effect
    on PWB
  • relationship is probably bi-directional
  • a reciprocal effects model might be more useful

29
Psychodynamic theory
  • Symptom of some intrapersonal conflict
    outgrowth of the individuals attempt to come to
    terms with internal conflict
  • Sullivan and Horney (1950s) deal with internal
    anxiety
  • Edwards (1982) come to terms with helplessness
    and fear of abandonment
  • Victims of incest Bradshaw (1988) escape the
    shame associated with the family of origin
  • Coleman (1982) 32 68 of female alcoholics had
    suffered neglect or abuse in their family of
    origin
  • Balzan (1998)
  • Khantzian (1985) medicating emotional distress
  • Brown (1985) illusion of control

30
addiction as obsessive compulsive disorder
  • OCD responds differentially to drugs that block
    serotonin reuptake in the CNS e.g. anafranil,
    Prozac
  • Assuming that addictive behaviour lies along the
    OCD spectrum , they should respond to these drugs
  • Good evidence for sexual preoccupation but not
    for other addictive behaviour

31
Inadequate personality theory
  • Addiction as a personality construct in which
    persistence is a featured element
  • Use drugs as a means of coping self esteem
    and inferiority
  • Emotional /psychic defect
  • Escapism
  • Inability to delay gratification drug use as a
    defense mechanism
  • Addictive personality
  • substantial overlap between different addictions
  • addiction as learnt behaviour

32
Learnt behaviour
  • Reinforcement
  • Underplays the idea of personality differences
  • Even animals use certain drugs compulsively under
    the right experimental conditions (Wikler, 1990)
  • No need to postulate psychodynamic variables
  • positive and negative reinforcement
  • Positive reinforcement
  • The individual receives a pleasurable sensation
    and is motivated to repeat it.
  • What is referred to as addiction is simply an end
    point along a continuum and indicates that a
    sufficient history of reinforcement has probably
    been acquired to impel a high rate of use in the
    user (McAuliffe and Gordon, 1980)
  • Often partial intermittent /schedule
  • Negative Reinforcement
  • Removal of noxious stimulus pain withdrawals
  • Focus on physical dependence criticism why
    use on methadone?
  • Psychological dependency remove anxiety
  • Explains craving the perception of withdrawal
    symptoms as being due to the absence of opiates
    will generate a burning desire for the drug

33
  • Two types of addicts
  • Euphoria seekers motivated by intense pleasure
  • compulsive
  • expensive
  • disruptive
  • illegality
  • Maintainers - stable
  • often controlled use
  • employed
  • rational choice

34
Problem Behavior Proneness
  • nor reinforcement per se but risk taking
  • deviant behavior not negative or pathological
    but different
  • the person likely to get into trouble
  • Continuum Conformity ------------------ Total
    non conformity
  • I Vs Me
  • Experimentation
  • Traits rebellious, independent, open to new
    experiences, tolerant, accepting of deviance in
    others, pleasure seeking, peer oriented
  • Transition prone

35
Walters (1990)
  • Drugs and crime in a lifestyle perspective
  • a cognitive system develops in the individual
    which is dedicated to supporting, buttressing and
    perpetuating the irresponsibility and self
    indulgence of adolescence.
  • learning eventually permits this thinking style
    to crystallize to the extent that the evolving
    lifestyle criminal finds shortsighted frivolity,
    unrestrained hedonism , intrusive action and
    rulelessness more rewarding than accountability,
    self discipline, interpersonal commitment and
    social conformity

36
Walters (1990)
  • Lifestyle Theory the presence of distorted
    cognitions can be traced back to earlier stages
    in the life of a person
  • Developmental process
  • Lifestyle evolves and unfolds in three distinct
    phases initiation (constructed) transitional
    (reinforced) and maintenance (solidified)
    (Walters, 2000)
  • identifies 8 cognitive styles sustain,
    reinforce and supplement an entrenched deviant
    lifestyle

37
errors
  • Mollification- diverging responsibility
  • Cutoff forget any potential risks incurred by
    illicit behavior
  • Entitlement
  • Power orientation
  • Sentimentality
  • Super optimism
  • Cognitive indolence
  • Discontinuity

38
mollification
  • Conveyed in statements that justify and
    rationalize drug seeking and crime oriented
    behaviors
  • Similar to neutralization
  • Victim stance seek to assuage guilt and anxiety
    consequential by adopting the mind set that they
    had no choice but to participate in thee
    activities because they were victims of nefarious
    socio-environmental circumstances
  • Minimization of harm done to others
  • Normalizing ones negative behaviors
  • Transferring blame to the victim

39
cutoff
  • Develop the capacity to eliminate deterrents
    quickly from consideration
  • Implosion flood of anger and emotion
    characterizes the cutoff process
  • Fuck it mentality
  • Drugs and alcohol

40
entitlement
  • Basis in the egocentricity of childhood
  • Global sense of ownership and privilege
  • Ownership, uniqueness and misidentification of
    wants as needs

41
Power orientation
  • Low self esteem
  • Zero state impotent weak and powerless
  • Eliminated by thoughts and actins designed to
    take control of a situation- power thrusting

42
sentimentality
  • Find ways to reconcile their discrepancies
    between their negative behavior and their
    positive self views
  • Helping the weak
  • Artistic or literary achievements

43
Super optimism
  • Most criminals realize that there is a chance
    that they will get caught but reason not this
    time
  • Magical and superstitious thinking

44
Cognitive indolence
  • Eventually become lazier and uncritical of their
    thoughts and plans
  • Swiftest possible results
  • Short cuts
  • nonvigilence

45
discontinuity
  • Lack of persistence and unpredictability
  • Lack of integration
  • Good intentions

46
ADDICTION AS A SOCIOLOGICAL CONSRUCT
  • Emphasize understanding of the individual located
    within specific social structures
  • The group impacts on the individuals behaviour
  • predisposing, initiating and maintenance
  • addictive behaviour as a socialisation process
  • addiction is a manifestation of failed or deviant
    socialisation
  • person's helplessness in the face of outside
    influences (hence loss of control)
  • three major sources family peers and media
  • but selective socialisation
  • Structural variables -

47
  • Anomie structural strain
  • Goals- means disjuncture individual adaptation
  • GoalsMeansConformistAcceptsAcceptsInnovatorAccepts
    Reject/blockedRitualistRejectAcceptRetreatistRejec
    tReject/blocked

48
Social learning
  • Edwin Sutherland (1939) differential
    association
  • Behaviour is learned
  • Behaviour is learned in intimate social groups
  • Depends on priority, intensity and duration
  • Involves techniques and motives

49
Control Theory
  • Internal control Reckless self efficacy
  • External control Hirschi social bonds
  • Involvement
  • Commitment
  • Attachment and
  • Belief

50
Subcultural Theories
  • Stress the importance of
  • Group socialisation
  • Identity change
  • Development of new value and normative systems
  • Learn to obey a different set of norms and to
    define yourself in those terms
  • Howard Becker becoming a marihuana user
  • How Vs why?
  • Learning socialisation subculture- identity
  • Motive for continued behaviour evolves through
    participation in the behaviour in the company of
    others
  • Learn to use the drug
  • perceive its effects
  • enjoy the effect
  • access supply
  • maintain secrecy
  • neutralise stigma though identification with
    the subculture

51
  • Selective Interaction / Socialisation Denise
    Kandel
  • Agents of socialisation
  • Parents long term impact, basic values
  • parental drug use some impact , opens up
    potential
  • Peers peer drug use , very important factor
  • - teens associate based on
    similarities in
  • lifestyles
  • imitation and social influence
  • cohesive groups form
  • friends are not chosen at random

52
Conflict Theory
  • macro
  • structural
  • class , income , power and neighbourhoods
  • alienation drug use
  • movement from recreational use to abuse more
    likely within impoverished populations (SES and
    Drug use Vs SES and drug use problems)

53
Criticisms
  • limited by simplistic approach to cause and
    effect
  • Any perspective that considers people as victims
    of their circumstances

54
GENERAL CONSIDERATIONS/ SUMMARY
  • biological theories give us insight into specific
    mechanisms relevant for understanding a certain,
    rather small, segment of the population
  • psychological theories help us understand
    willingness and potential for using drugs and the
    personality characteristics associated with users
  • drug use is learned an reinforced within a
    particular group setting
  • selective socialisation explains entrance into
    the group
  • Involvement in the group provides rationale for
    escalation and continued behaviour
  • Different influences are critical at different
    life stages

55
INTEGRATED AND MULTIVARIATE MODELS
  • ADDICTION TO AN EXPERIENCE (Peele, 1998)
  • Addictive experiences stems from
  • Pharmacological
  • Physiological
  • But takes its ultimate form from
  • Cultural contructions
  • Individual constructions
  • What is addiction?
  • - Dynamic social learning process
  • - Rewarding
  • - Ameliorates urgently felt needs
  • - Damages ability to cope

56
Elements of the addictive experience
  • 1. Potent modifiers of mood and sensation
  • Pharmacological action
  • Learned and symbolic significance
  • 2. Diminution of pain, tension and awareness
  • 3. Enhanced sense of control, power and self
    esteem
  • 4. Simplification, predictability and immediacy
    of experience

57
Susceptibility to Addiction
  • A. Social and cultural factors
  • 1.Social class
  • Social class differences in addiction appear to
    be persistent and substantial
  • Based on differences in attitudes as well as
    behaviour
  • Broadening of awareness of the forms of addiction
    indicate that higher SES addictions simply appear
    in different guises e.g. anorexics and compulsive
    runners middle class backgrounds
  • 2. Peer and parental influence
  • Influences not only initiation but more
    importantly patterns of use
  • 3.Culture and ethnicity
  • Where the use of a substance is comfortable and
    socially regulated both as to style of use and
    appropriate time and place for use, addiction is
    less likely
  • E.g. drinking cultures
  • Ethnic patterns for drinking are robust
  • Achievement motivation Chinese and Japanese
    (high) vs. Indian and Eskimo (low)
  • Societies that value demonstration of male power
    but that make such demonstration difficult
    drinking is heavier and associated with
    antisocial aggression
  • The cultural stereotype for the drug infiltrates
    the kind of relationships people have with the
    substance
  • Groups with lower drug or alcohol addiction rates
    express their distress and potential for
    addiction in other ways e.g. Jews obesity
    problems youth thinness

58
Situational factors
  • B. Situational factors
  • Availability e.g. Vietnam (Lee Robins, 1978)
  • Stress and control of stress
  • Relapse precipitated by stressors and negative
    emotional reactions to them
  • 3. Offers magical solutions
  • Social support and intimacy
  • 4. Opportunity for enterprise and positive rewards

59
Individual factors
  • Individual factors
  • Lack of values towards moderation, self restraint
    and health
  • Lack of achievement motivation and antisocial
    attitudes lifestyle
  • Fear of failure, intolerance of uncertainty,
    belief in magical solutions and low self esteem
    (locus of control)

60
CHEMICAL DEPENDENCY
  • TERMINOLOGY - WHO definitions (cited in Ghodse,
    1989)
  • What is a drug? 'Any substance that, when taken
    into the living organism, may modify one or more
    of its functions

61
Terminology cont
  • Drug Abuse - 'persistent or sporadic excessive
    use inconsistent with or unrelated to acceptable
    medical practice'
  • Drug Dependence - a state, psychic and sometimes
    also physical, resulting from the interaction
    between a living organism and a drug,
    characterised by behavioural and other responses
    that always include a compulsion to take the drug
    on a continuous or periodic basis in order to
    experience psychic effect, and sometimes to avoid
    the discomfort of its absence. Tolerance may or
    may not be present'

62
cont
  • Psychological dependence a feeling of
    satisfaction and a psychic drive that requires
    periodic or continuous administration of the drug
    to produce pleasure or to avoid discomfort
  • Physical dependence - an adaptive state
    manifested by intense physical disturbance
  • Tolerance - 'a state of reduced responsiveness to
    the effects of a drug caused by its previous
    administration
  • Interaction

63
DSM-IV - DEFINITIONS
  • Substance Abuse
  • A maladaptive pattern of substance use, leading
    to clinically significant impairment or distress
    as manifested by one (or more) of the following,
    occurring within a twelve month period
  • Recurrent substance use resulting in a failure to
    fulfil major role obligations at work, school, or
    home
  • Recurrent substance use in situations in which it
    is physically hazardous
  • Recurrent substance related legal problems
  • Continued substance use despite having persistent
    or recurrent social or interpersonal problems
    cause or exacerbated by the effects of the
    substance (American Psychological Association,
    1994182-3)
  • Substance Dependence see overhead

64
THE PROCESS OF CHEMICAL DEPENDENCY
  • Continuum
  • Complete abstinence ? dependency
  • Differ in intensity of use and consequences
  • Cattarello et al (1995) 'some people never
    experiment some experiment and never use again.
    Others use drugs irregularly or become regular
    users, whereas others develop pathological and
    addictive patterns of use (p.152)
  • No firm boundaries between the pints on a
    substance use continuum

65
MODELS
  • Doweiko (2002) -
  • Level 0 - total abstinence from drug use
  • Level 1 - rare/social use of drugs
  • Level 2 - heavy social use/early problem use of
    drugs
  • Level 3 - heavy problem use/ early addiction to
    drugs
  • Level 4 - clear addiction to drugs
  • The focus is on physical dependency
  • Doweiko does not accept behavioural or activity
    addictions because 'there is little evidence that
    non drug centred behaviours can result in
    physical addiction
  • Addiction is viewed as
  • A primary disease
  • Multiple manifestations
  • Progressive
  • Potentially fatal
  • Loss of control
  • Preoccupation

66
Muisener (1994)
  • Adolescent chemical use can be construed as
    occurring in different stages along a continuum.
    Young persons progress, regress through, or stay
    at different stages according to varied
    biological, psychological and social factors
  • The Adolescent Chemical Use Experience Continuum
    (ACUE)
  • Stage 1 experimental use - learning the mood
    swing
  • Stage 2 social use - seeking the mood swing
  • Stage 3 operational use - preoccupation with the
    mood swing
  • Stage 4 dependent use - using to feel normal

67
Ungerleider Beigel (1980)
  • Classification scheme for identifying different
    types of drug usage, excluding drugs used for
    therapeutic reasons
  • Experimental drug use participated in primarily
    by youth and motivated by curiosity
  • Recreational drug use indulged in by many for
    pleasure with one or more drugs
  • Situational or circumstantial drug use ingested
    for specific effects for example use of
    stimulants
  • Intensified drug use regular drug use that
    interferes with one's behaviour and relationships
    at home at work or at play
  • Compulsive drug use obtaining drugs becomes the
    overriding concern of daily life

68
Parker et al (2000)
  • Normalisation hypothesis
  • Developed the concept of drug pathways. They
    identified 4 drug status' groups'
  • Current users - use one or more illicit drugs
    regularly
  • Former users - have tried, don't use now and
    dont expect o use again
  • In transition - currently dont use, but expect
    to use in the future
  • Abstainers - never tried, and dont expect to in
    the future
  • - Actions and decisions made or chosen by young
    people can help shape the particular journeys
    they take
  • there can be changes in drug behaviour along
    these pathways

69
Normalisation hypothesis
  • The visible integration of recreational drug use
    into mainstream culture led to the proposal of a
    normalisation hypothesis based on the following
    criteria
  • Drug availability
  • Drug trying
  • Drug use
  • Being drug wise
  • Future intentions
  • Cultural accommodation of the illicit

70
THE ADDICTION CYCLE
  • THE ADDICTION CYCLE
  • Exposure
  • People turn to experience to modify feelings
  • Abandon all functional coping efforts
  • Addictive experience becomes sole means for
    asserting control over addicts emotional life
  • Remission
  • Mix of addictive and functional coping shift
  • Stress lessens, situations improve, successful
    experiences foster self efficacy addictive
    involvement becomes less necessary
  • Change in a. external situations b. self efficacy
    and goals c. reward value attached to addictive
    experience
  • Invest more heavily in activities that drug use
    interferes with and experience increased rewards
  • Final stage rewards are firmly established no
    consideration of returning to lifestyle

71
THE ADDICTIVE CAREER
  • TRANSITION FROM USE TO ADDICTION (ORFORD, 2002)
  • Transition from appetitive beh that constitutes
    acceptable moderate indulgence to highly
    troublesome and noticeable excess
  • From consumption that is manageable to one that
    is unmanageable
  • Control is diminished
  • Gradual development
  • Conflict liking it but knowledge of the harm it
    is doing

72
Process of social change (Parker et al, 1988
  • Deterioration of previous friendships
  • Deterioration of previous recreational patterns
  • Reduction of social options
  • Identification with other drug users
  • Financial deprivation
  • Different pathways into addiction
  • Contributing factor of consequence thereof

73
General Progression theory
  • Change in patterns of use
  • Change in motivation
  • Change in norms regarding use
  • Discrimination time and place
  • Discrimination is eroded and behaviour
    generalized to additional stimuli and setting
  • Preoccupation cognitive component
  • Strong appetite has at least three components
  • Enhanced affective attachment
  • Increased mental commitment and orientation
    towards the object
  • Increased regularity, volume or intensity of
    consumption or activity.

74
DRUG ACTION
  • Pharmacology - the biochemical properties of
    drugs and how they interact with living tissue
  • Not the whole story of drug use and effects
  • While drugs have potential for specific effects
    on humans, whether potential is released is not
    simply a matter of pharmacology
  • Interaction - 3 factors
  • 4 crucial pharmacological dimensions
  • drug action
  • factors that influence drug action and drug
    effects
  • drug classification
  • drug dependence

75
DRUG ACTION BASICS
  • interconnection between neurology and chemistry
  • neurons - nerve cells that send electrical
    impulses or signals from one part of the body to
    another
  • electrical impulses determine both autonomic and
    voluntary functions
  • neurotransmitters -

76
neurotransmitters -
  • 'chemical messengers'
  • neurons release chemicals that are conveyed from
    one site to another
  • released at the synapse
  • extremely rapid
  • 'lock and key ' hypothesis (Ray and Ksir, 1996)
  • when neurons recognise specific neurotransmitters
    they translate signal into certain action
  • they bind to a receptor
  • E.g. heroin fits into the receptors that control
    breathing and heart rate. A sufficiently large
    does can shut down these functions overdose.THC
    does not bind to receptors in brain that control
    breathing and heart rate impossible to overdose
    on marihuana
  • E.g. hippocampus and cerebral cortex control
    thinking and short term memory, rich in receptors
    that bind to THC THC can diminish user's short
    term memory and disorganise thinking process
  • 'lock and key' bad fit
  • Each effect of each drug is determined in large
    part by the fit between the drugs chemistry (the
    key) and the receptors located at specific sites
    in the brain (the lock)
  • Imp to distinguish between drug action and drug
    effects which include
  • - set
  • Setting
  • expectations

77
ROUTE OF ADMINISTRATION
  • How a drug is taken influences drug effects
  • 3 methods
  • inhalation
  • injection
  • oral administration

78
DOSE
  • ED effective dose
  • ED's differ according to the effect under
    consideration and organism population
  • LD - lethal dose
  • With some drugs LD and ED are very close together
    e.g. heroin
  • Combining drugs
  • Addictive 112
  • Antagonistic 110
  • Synergistic 114 e.g. alcohol and barbs

79
TOLERANCE
  • Diminishing effects
  • Body adjusts to a given drug
  • Requires larger doses
  • Behavioural tolerance

80
BLOOD BRAIN BARRIER
  • Presents materials from the blood from entering
    the brain
  • Semi-permeable
  • BBB has several important functions
  • Protects the brain from foreign substances in the
    blood that may injure the brain
  • Protects the brain from hormones and
    neurotransmitters in the rest of the body
  • Maintains a constant environment for the brain
  • Lipid (fat) soluble molecules rapidly cross
    through the barrier

81
FACTORS THAT INFLUENCE DRUG EFFECTS
  • Pharmacological factors
  • identity
  • dose
  • potency and purity
  • drug mixing
  • route of administration
  • habituation
  • the drug half life
  • peak effects
  • Psychological and social factors
  • set
  • expectations
  • intelligence
  • mental state
  • personality
  • setting

82
Drugs of abuse and their effects
83
ADOLESCENT SUBSTANCE ABUSE
  • Adolescence as a period in the lifespan
  • Boundaries of adolescence
  • Transition risk and opportunity
  • Late modernity expended period
  • Status ambiguity
  • Rites of passage
  • Contexts of adolescent development family ,
    peer group and school
  • Aspects of adolescent development
  • physical and sexual
  • cognitive
  • social
  • Identity moratorium and experimentation
  • dependence and independence

84
Risk and Resiliency
  • RISK
  • Risk factors in relation to substance abuse are
    those factors that are associated with or are
    precursors of that abuse (Hawkins, Catalano and
    Miller, 1992).
  • Several factors have been identified that
    differentiate those who use drugs from those who
    do not.
  • Factors associated with greater potential for
    drug use are called risk factors.
  • Stress might be considered a universal and
    comprehensive risk factor and it creates a large
    part in creating distress and vulnerability
    (Gullotta et al, 1995). Generally the more
    stressors that a child is exposed to, the more
    vulnerable he or she becomes.

85
RESILIENCY
  • Those factors associated with reduced potential
    for drug use are called protective factors or
    resiliency factors.
  • Resiliency factors are those influences that
    protect against vulnerability and enable
    sustained competent functioning even in the
    presence of major life stressors (Matsen, Best
    and Garmezy, 1990)

86
INTEGRATED DOMAINS
  • Norman (1995) whether we are talking about risk
    or resiliency, it is crucial to explore at least
    three integrated systems
  • (a) the characteristics of the individual
    associated with greater risk or resiliency
    (personal domain)
  • (b) the family interaction system in which the
    young person is absorbed (family)
  • (c) the school and community milieu in which the
    a1dolescent is embedded, including the peer
    domain.
  • Thus risk and protective factors encompass
    psychological and behavioural, family and social
    (peer and school) characteristics.

87
PERSONAL FACTORS ASSOCIATED WITH SUBSTANCE
MISUSE.
  • Four distinct aspects of the adolescent
    personality domain that should be considered
  • (a) conventionality versus unconventionality,
  • (b) emotional control,
  • (c) personal functioning and
  • (d) social relatedness.

88
RISK
  • Brook et al (1990)having a difficult childhood
    temperament manifested by such factors as
    negative mood states, temper tantrums,
    irritability and withdrawal.
  • Shedler and Block (1990) childhood emotional
    distress, depression and high anxiety.
  • Block et al, 1988 Cloninger et al, 1988 Penning
    and Barnes, 1982 Shelder and Block, 1990
    behaviour problems such as hyperactivity,
    aggression and rebellion, poor impulse control,
    sensation seeking, low harm avoidance and
    inability to delay gratification.
  • Jessor and Jessor (1977) Kandel et al, (1986)
    Unconventionality, expressed in lack of
    attachment or low commitment to school, having
    attitudes favourable to drug use and associating
    with drug using peers
  • Penning and Barnes (1982) Alienation from
    dominant societal values, including low
    religiosity

89
RESILIENCY
  • Genetic and biological factors easy temperament
    and intellectual capabilities have emerged in
    several studies as resiliency related (Werner and
    Smith. 1982 Garmezy, 1985 Masten et al, 1990).
  • Sense of self-efficacy Rutter (1984) considers
    self-efficacy to be a feeling that one has
    worth, that one can deal with things that come
    up, and that one has at least some control over
    important events.
  • Involves several related things a sense of
    self-esteem and self confidence and a belief in
    ones own ability to have an influence over ones
    internal and external environments.
  • A realistic appraisal of the environment (Garmezy
    and Masten, 1986 Werner, 1986).
  • Possessing a variety of social problem solving
    skills that reinforce ones sense of competency
    and self esteem (Werner and Smith, 1982 Pentz et
    al, 1989).
  • Having a sense of direction or mission, being
    able to understand and respond to anothers
    feelings (empathy) and having a sense of humor
    (Kumpfer, 1983).
  • Gender differences associated with resiliency
    Boys tend to be less resilient than girls in
    early childhood (Werner and Smith, 1982).
  • Changes substantially in adolescence (Gullotta et
    al, 1995). In the second decade it is girls who
    become more vulnerable

90
FAMILY FACTORS
  • Powerful socializing agent
  • Quality of the attachment and bonding processes
    between parent and infant in the first few years
    of life are important for the later emotional
    health of the individual.
  • Family relationships during adolescence have
    important flow on effects for a number of
    domains, such as autonomy and later independence
    of the individual (Coleman and Hendry, 1990)
    adolescent personality (Heaven, 1997), individual
    pathology (Scott and Scott, 1987) and problem
    behaviour (Peiser and Heaven, 1996 Shaw and
    Scott, 1991).

91
family domain
  • The family domain may be further subdivided into
  • the parental marital relationship domain,
  • parental drug use and personality domains,
  • parent adolescent relationship domain and
  • sibling domain.

92
Parental marital relationship domain
  • Family conflict is associated with the childs
    delinquency and drug use (Robins, 1980)
  • Parental conflict may be greater risk factor than
    structural variables, such as parental absence
    (Farrington, Ghallager, Morley, Ledger, and West,
    1985).

93
Parental drug use and personality domains
  • Parental drug use is related to the childs drug
    use.
  • Parental attitudes toward drug use also play a
    role with parents who are tolerant of drug use
    being more likely to have children who use drugs
    (Barnes and Welte, 1986)

94
Parent adolescent relationship domain
  • Parent adolescent relationship domain
  • Mutual attachment influential in terms of
    adolescent drug use.
  • Parents of non-users, report greater warmth (more
    child centeredness, affection and communication)
    and less conflict in their relationship with
    their children.
  • Discipline structured discipline serves as a
    barrier to adolescent drug use (Kandel Andrews,
    1987)
  • Appropriate parental monitoring is effective in
    reducing drug use (Patterson, Chamberlain Reid,
    1982).
  • Authoritarian or power assertive techniques may
    be detrimental and permissiveness seems to have
    no effect (Brook Brook, 1986)

95
Sibling domain
  • Several investigators have found that an
    adolescent with a sibling who uses drugs has an
    increased probability of drug use.
  • Brook et al (1981) a sibling relationship
    characterized by conflict, less admiration, less
    satisfaction and less sibling identification is
    related to inner tension and psychic distress,
    less conventional attitudes and consequently more
    drug use.
  • A good sibling relationship may buffer against
    the effects of a bad parental relationship.

96
Gulotta et al 1994
  • highlight some of the main risk factors relating
    to the familial domain, leading to vulnerability
  • Being born into poverty
  • Living with chronic familial tension and discord
  • Having dysfunctional parents who are physically
    or sexually abusive, who abuse substances and who
    suffer from serious mental illness
  • Membership in a family where there is little
    warmth, support or positive bonding and there is
    parental non directiveness, permissiveness and
    inadequate supervision
  • Experiencing the death of a significant adult
    before a child has reached the age of eleven
  • Living in a neighborhood where there is a great
    1deal of violence and turmoil

  • (Gullotta
    et al, 199451)

97
Peer domain
  • Risk
  • Glantz and Pickens (1991) drug use appears to be
    a function of social and peer factors while abuse
    is more a function of biological and
    psychological processes.
  • Peers provide models of use, access to drugs and
    the motive and support to initiate use.
  • Associating with drug taking peers and having
    attitudes favourable to drug use
  • Substance use takes place within the context of
    peer clusters, which consist of best friends or
    very good friends.

98
Resiliency
  • peer warmth, conventionality, values and academic
    achievement can also be important in protecting
    against drug use. It is also important to
    understand and investigate the idea that the
    influence of peers changes as the adolescent
    matures.
  • Maintaining successful friendships and peer group
    memberships in adolescence may be an important
    factor in the healthy social and psychological
    development of the young person.
  • Gavin and Furman (1989827) Without being
    connected to the peer group, one may be left
    without an important source of support during a
    period of physical, emotional and social
    upheaval.

99
THE SCHOOL CONTEXT
  • Schools have a major influence on adolescent
    development. Not only are many friendships formed
    there but, as society becomes more complex, with
    increasing influence paced on the acquisition of
    specialist skills and training for jobs, so the
    importance of the school as a social institution
    is gaining in importance


  • (Heaven, 2001)

100
  • RISK
  • young people experiencing a very important
    transition, that from primary to secondary
    school.
  • accompanied by a move away from close friends and
    familiar surroundings
  • associated with new expectations and teaching
    methods.
  • new curricula to select from and new teachers to
    contend with.
  • Moving into a large and impersonal school,
    separated from old friends and what is familiar
    may serve to lower the adolescents self esteem
    and confidence.
  • Low self esteem may give rise to negative
    attitudes to school, which could increase truancy
    and other unacceptable behaviours (Rice, 1999).
  • Schools that are rigid and authoritarian in their
    disciplinary policies tend to promote disrespect
    for authority.
  • Low perceived peer affect towards school, low
    academic performance, low perception of freedom
    in school and negative attitudes towards school
    have been identified by Scheier and Newcomb
    (1991) as risk factors for experimentation with
    drug use

101
PREVENTION
  • Risk and Resiliency factors
  • Aimed at enhancing the individuals own
    responsibility for their health as well as that
    of others
  • Directed towards the progress of public heath and
    mental health
  • Can be carried out on diverse levels
  • Most in particular within social sections like
    school, family and workplace (van der Stel, 1998)

102
Levels of Prevention
  • Primary prevention
  • Intervention before a health problem has arisen
  • Breaking though the network of causal links which
    surround a problem by taking away one or more
    links in the chain
  • Influencing the behaviour and views of the target
    group
  • Education and information
  • Utilises various strategies
  • Holds various goals
  • Emphasis on attitude to life and social skills
  • Intermediary aim personal character building
  • Intended result not using drugs
  • Combined action by different people

103
Secondary prevention
  • The early detection of an already developing but
    not yet clinically visible illness or health
    problem, in such a way that by early intervention
    the prognosis can be more favourable

104
Tertiary Prevention
  • Preventing a relapse, or limiting the effects of
    residual symptoms in the case of a clinically
    overt illness or an overt behavioural problem in
    its early stage
  • Closely allied to treatment activities

105
NEW CLASSIFICATION
  • Universal approaches directed to the whole
    population
  • Selected programmes designed for members of a
    whole at risk subdivision of the whole
    population, regardless of individual risks
  • Indicated addressed at particular at risk
    individuals, who are showing early signs of
    problems

106
PRIMARY PREVENTION
  • The goal of primary prevention in general is to
  • anticipate problems
  • reduce the no of new cases
  • promote competencies that promote against the
    development of problems
  • encourage optimal health
  • The goals of primary prevention in the substance
    abuse field are to
  • determine who is at risk for substance abuse
  • reduce the number of people who abuse substances
  • promote behaviours that protect against the use
    of substances
  • encourage healthy behaviour that is incompatible
    with the use of substances
  • developmental period that is targeted is early
    adolescence
  • onset of gateway substances develops at this time
  • also use interferes with essential maturational
    process and development

107
Mission Statement - sedqa
  • "To ensure that all members of society are
    served with the right information about substance
    abuse and to provide training programmes
    regarding healthy living, appreciation, of one's
    abilities and self determination."

108
Primary Schools Programmes
  • 'Tfal Favur Ambjent Liberu' (T.F.A.L.)This is a
    comprehensive programme targeting children from
    Kinder 2 through to Year 6. T.F.A.L workbooks are
    distributed to each child and class teacher. The
    workbooks are accompanied by lesson plans. Each
    workbook is age appropriate and regularly
    updated. It is a skills based programme which
    amalgamates formation and information based
    activities. The workbooks focus on three main
    topics, namely, 'Mental hygiene', 'Social
    relations' and 'Wise use of medicinals'.
  • BABESThis is part of the T.F.A.L primary
    prevention programme. It targets Year 3 children
    (7/8 years) and is comprised of six one-hour
    classroom sessions, with approximately 20
    children in each class. sedqa-trained
    facilitators deliver the programme once weekly
    using visual aids such as puppets and flash cards
    to recount a succession of six stories. The Babes
    programme is a life skills based programme
    originally conceived in the United States and
    adapted for use in Malta. The purpose of BABES is
    to enable children to learn and practice
    living/loving skills and make positive early
    decisions about alcohol and other drugs.
  • The BABES Follow-upThis programme is based on
    the same concept as the BABES. It is intended to
    compliment the BABES programme, to provide
    continuity and strengthen the skills that the
    children learn in year 3. The programme runs over
    three to four sessions each 60-90 minute. During
    the current scholastic year this programme is
    being reserved exclusively to Year 5 students in
    Government schools, and to a small sample of
    Church and Private Schools.
  • 'Skola Sajf'Every year, sedqa Agency, together
    with the Skola Sajf coordinators from the
    Education Division organizes a special three day
    programme for year 4, year 5 and year 6 children
    attending Skola Sajf. The programme is delivered
    by the BABES facilitators.
  • Special SchoolsThis project aims at reaching out
    to children with disabilities. Our target
    audience is children with disabilities in
    government, private and church schools, and
    schools for children with disabilities, including
    Guardian Angel, Eden Foundation, Wardija School
    and San Miguel. Rather than expecting individuals
    to try to adapt to sedqa's T.F.A.L prevention
    programme, our aim is to recognize and respect
    individual differences by making our programmes
    more flexible for the target audience. This
    requires that our programmes be tailor-made to
    suit such differences.

109
Secondary Schools Programmes
  • CrossroadsSix sets of lesson plans and handouts,
    dealing with everyday issues vis--vis substance
    abuse and other addictions, for Form 1, 2 and 3
    teachers and students. Subjects include PSD and
    Social Studies.
  • 'Jien u l-Ohrajn'Two-day non-residential
    seminars for Form 3 students coming from
    different schools where they explore, share, and
    learn different life-skills, research methods and
    public speaking skills.
  • 'Ghini Nikber'A 3-hour course for Form 1, 2 and
    3 students in government schools and a sample of
    Church and Private schools Topics dealt with
    include team building, peer-pressure, feelings
    and self-esteem. Each group of students is
    visited 3 consecutive times for a one hour
    session per visit.
  • Staff MeetingsRegular evaluation and updating
    meetings with teaching and other staff regarding
    sedqa's programmes in secondary schools. These
    meetings also serve to discuss and introduce new
    concepts and approaches.
  • Prefects'/Leadership CourseOne-day leadership
    skills training course for prefects,
    sub-prefects, bus prefects, students' council
    members and other students who are potential
    leaders in all Forms.
  • Information Awareness SeminarsTwo-and-a-half-ho
    urs seminars about alcohol, drugs and their
    effects. The sessions are divided into three
    parts, a film show, discussion in small groups,
    and a presentation about the effects of the
    substances in questions.

110
Secondary Prevention Programme
  • Overview
  • This mainstay of this Team is the STORM
    programme, which aims to provide students with
    information and skills on how to manage present
    and future problematic situations without
    resorting to substances or engaging in other
    risky behaviour. This outreach programme also
    aims to identify young persons at high risk of
    misusing substances or those who already started
    experimenting with substances. Further outreaches
    are conducted at parties and entertainment areas.
    The Team also deals with adolescents who seek
    sedqas help through the helpline or drop-in
    services. 
  • Brochures
  • Printed leaflet STORM booklet STORM programme
    material
  •  
  • Eligibility
  • Young people who are at risk or started
    experimenting with substances. The STORM
    programme targets students in secondary schools
    at Form 4 level, and also post-secondary schools.
  •  
  • Procedure
  • Young people who are at risk of substance abuse
    or have already entered the experimenting stage
    are identified by members of the Secondary
    Prevention Team during their outreaches or school
    interventions. Other referrals are made by the
    community services within sedqa, through the
    Helpline, the Court Services Team and also by the
    Safe Schools team within the Education
    Department.

111
PREVENTION TECHNOLOGIES
  • Traditional intervention approaches
  • information education
  • fear arousal
  • moral appeal
  • affective education
  • effectiveness of traditional approaches
  • Psychosocial intervention approaches
  • psychological inoculation
  • resistance skills training
  • personal and social skills training
  • mass media approaches

112
EVALUATION
  • Awareness of the extensiveness of substance use
    has led to numerous attempts at prevention,
    particularly in schools. Evaluation of prevention
    programs indicates that improvement in knowledge
    and some attitude change may occur however,
    there is little evidence that these programs
    serve to actually reduce or eliminate drug use
    (Bangert-Drowns, 1988). This lack of evidence of
    program effectiveness may be due to at least two
    factors the complexity of risk factors leading
    to adolescent substance abuse (Beman, 1995) and
    the difficulty of evaluating prevention programs.

113
INTERVENTIONS
  • Matching Hypothesis (Miller and Huster, 1989)
  • There is no single superior approach to
    intervention for all individuals
  • Different individuals respond best to different
    intervention approaches
  • It is possible to match individuals to optimal
    interventions thereby increasing treatment
    effectiveness and efficiency

114
PROCHASKA AND DICLEMENTE (1992)
  • Transtheoretical model
  • People are ultimately capable of making an
    informed choice in their own best interest
  • Circular process that includes 6 stages (see
    graphic model)
  • Identifying the stage of change is essential for
    deciding upon appropriate goals and the means of
    attaining these goals
  • Ignoring the different stages of change often
    results in the offer of identical and usually
    inappropriate interventions to individuals with
    very different needs
  • A person may proceed through each stage several
    times before achieving stable change

115
THE STAGES
  • Precontemplation characterised by defensiveness
    about substance abuse
  • Contemplation the person is aware that a
    problem exists but is ambivalent about making a
    change or has anxiety about what the change will
    mean.
  • Preparation the person intends to make a change
    in the near future or has unsuccessfully taken
    action in the last year.
  • Action the person takes action to change his or
    her behavior or environment to overcome a problem
    behaviour such as becoming abstinent or cutting
    down on drug use
  • Maintenance where the person consolidates gains
    and works to prevent relapse
  • Relapse - may occur repeatedly and is considered
    a normal part of the behaviour change process

116
