ATTENTION-DEFICIT/HYPERACTIVITY DISORDER
A. Either (1) or (2) (1) Six (or more) symptoms
of inattention (2) Six (or more) symptoms of
hyperactivity-impulsivity. (Symptoms have
persisted for at least 6 months to a degree
that is maladaptive and inconsistent with
developmental level).

ATTENTION-DEFICIT/HYPERACTIVITY DISORDER
A. Either (1) or (2) (1) Six (or more) symptoms
of inattention (2) Six (or more) symptoms of
hyperactivity-impulsivity. (Symptoms have
persisted for at least 6 months to a degree
that is maladaptive and inconsistent with
developmental level).
B. Some hyperactive-impulsive or inattentive
symptoms that caused impairment were present
before age 7 years.

ADHD
  • Controversial diagnosis. Symptoms also occur in
    healthy children.
  • For diagnosis, symptoms must occur in various
    settings, be reported by multiple informants, and
    interfere with the childs functioning.
  • Inattention tends to persist throughout childhood
    and into adulthood hyperactivity and impulsivity
    tend to decrease with age.

13
EPIDEMIOLOGY
  • Estimated prevalence 3 - 5 of school-aged
    children.
  • More common in boys than girls.
  • Found in all cultures, but rates vary
    significantly.

14
ADHD CAUSES
  • Exact etiology is unknown.
  • History minimal brain damage theory -- mixed
    evidence many brain-damaged children do not
    evidence hyperactivity if anything, they tend to
    be underactive.
  • In the late 1970s inattention was seen as the
    core symptom. Attention-deficit disorder was
    introduced in 1980 (DSM III).

15
ADHD CAUSES
  • Familial aggregation
  • Genetic factors
  • Researchers are honing in on two genes
  • a dopamine-receptor gene on chromosome 11
  • the dopamine transporter gene on chromosome 5

16
ADHD CAUSES
  • Biological risk factors
  • exposure to toxins (e.g., lead)
  • episodes of oxygen deprivation during birth
  • maternal smoking during pregnancy
  • maternal drinking

17
ADHD CAUSES
  • Familial factors
  • disruption (e.g., frequent moves divorce)
  • parental antisocial behavior
  • marital conflict
  • intrusive, over-controlling parents --but cause
    or effect??
  • when childs behavior improves as a result of
    treatment, parents have been found to become less
    controlling.

18
STUDY EXAMPLE HOFSTRA, van der ENDE, VERHULST,
2002
  • Parent reported behavior problems (measured in
    1983) of children ages 4-16
  • Off-springs diagnostic status measured some 15
    years later (all children are now adults)
  • what is the association between parent reported
    childhood problems and adult psychopathology?

19
STUDY EXAMPLE HOFSTRA, van der ENDE, VERHULST,
2002
  • Parent measure Child Behavior Checklist (CBCL)
    (Achenbach, 1991)
  • Three general scores (cut-off82 percentile)
  • CBCL Total Score
  • Externalizing Score
  • Internalizing Score
  • Eight symptom scales (cut-off 95 percentile)

20
MAIN INDEPENDENT (PREDICTOR) VARIABLE
  • Deviance on the CBCL, as defined for the
    general scores and the symptom scale scores

21
MAIN OUTCOMES
  • Anxiety disorder
  • Mood disorder
  • Substance abuse/dependence
  • Disruptive disorder
  • Antisocial personality disorder
  • Attention-Deficit disorder (with or without
    hyperactivity)

22
  • Do parent ratings on the CBCL predict risk for
    adult psychopathology?
  • Are there gender differences in the continuity of
    childhood to adulthood psychopathology?
  • What findings surprised you the most?
  • What are the public health implications of this
    study?

23
HOFFSTRA ET AL., MAIN RESULTS
  • High levels of childhood behavioral and emotional
    problems predict adult psychopathology
  • The CBCL Total Problem score as a general
    indicator of malfunctioning in children was
    associated with more diverse problems among women
    than men.

24
HOFFSTRA ET AL., MAIN RESULTS
  • Attention problems did not predict any adult
    disorders when analyses adjusted for other
    symptoms scales
