Randomized, Placebo-Controlled Clinical Trials of
Medication for the Treatment of CD
  • 13 studies, 559 subjects, 9 (8?) positive for
    medications, 4 (5?) equivocal
  • Agents studied Li, DVPX, Risperidone,
    Haloperidol, Molindone, Methylphenidate (MPH),
    CBZ, Vitamins
  • Average Duration 10 weeks, no long-term follow
    up, few comparative studies, small samples
  • BUT antipsychotics are most commonly prescribed
    (60-80) for aggression, regardless of diagnosis

Psychopharmacology of Aggression Effects of
Stimulants in ADHD A Meta-analysis
  • 28 studies
  • Criteria ADHD, peer reviewed, placebo-controlled,
    age lt18,scaled aggression
  • 2 with MR and CD as primary diagnoses each rest
    were ADHD 75 comorbid with ODD,CD
  • Average N24
  • 88 boys ? age 9.7 (7.7-14.4)
  • MPH in 75 (dose 24 mg/day) duration 13 days

Connor et al, 2002

Psychopharmacology of Aggression Effects of
Stimulants in ADHD
  • Overt aggression
  • Clinician (d .77)
  • Parent (d .57)
  • Teacher ratings (d .93)
  • All significant
  • Presence of MR and CD/ODD reduces Effect Size
  • AMPH and MPH equally effective (.8) PEM more
    (1.6)

Connor et al, 2002
9
Psychopharmacology of Aggression Effects of
Stimulants in ADHD
  • Covert aggression
  • Clinician (d .81) significant
  • Parent (d.37)
  • Teacher ratings (d.54) not significant (but
    wide range, only seven studies)
  • Drug type did not make a difference, duration and
    dose weakly contributed
  • Overall sample age correlated positively with
    effect size no gender effects

Connor et al, 2002
10
Psychopharmacology of Aggression Effects of
Stimulants in ADHD
  • Conclusion Stimulants have significant effects
    on aggression (especially overt, especially when
    ADHD is primary diagnosis and not comorbid with
    CD, MR) and maybe in older subjects
  • Limitations
  • Not all double blind
  • Short duration
  • No long term follow-up
  • Other comorbidities? PTSD, bipolar

Connor et al, 2002

The Aggression SystemInfluences and Limits
Psychiatric Trauma related pathologies
Environment (e.g., substances, socialization,
education)
Aggression System
Development and Maturation (e.g.,
diversification of affect, intentionality,
cruelty)
Constitution (e.g., genetics, perinatal injury)
12
Is there reason to think that trauma plays a role
in disturbances of aggression?
  • Developmental epidemiological studies (Widom,
    1989)
  • Community violence exposure studies (Osofsky,
    1995 Schwab-Stone, 1999)
  • Clinical self report studies (Burton et al, 1994)
  • Structured interview studies (Steiner et al
    1997 Cauffman et al 1998 Steiner et al 2002)
  • Transcultural studies (Aichhorn, 1935 Rushkin
    et al, 2002)

Components of the Aggression System Which Should
Be Affected by Trauma
  • Primary Appraisal Defenses YES Feldman,
    Araujo Steiner, 1996 Steiner, Garcia and
    Matthews, 1997
  • Affective Activation Anxiety and Aggression
    often go together YES- Steiner, Garcia and
    Matthews, 1997 Cauffman et al, 1998 NEW DATA
  • Secondary Appraisal Restraint, Impulse control
    is impaired as a function of trauma YES

This profile leads to reactive/affective/defensive
(RAD) aggression

How do we get from psychiatric trauma to
reactive/affective/defensive aggression?
  • Eysenks antisocialization hypothesis high
    levels of anxiety in high criminogenic
    environments predict future maladaptive
    aggression in adolescents
  • LeDouxs anxiety/active coping hypothesis trauma
    induced anxiety can be controlled by active
    coping (in this case of criminogenic
    environments involving aggression)
  • Posts PTSD kindling hypothesis Repeated
    traumatization leads to increasingly facile
    affective activation which becomes a mixture of
    anxiety, depression, anger

Divalproex Sodium for the Treatment of Severe CD
in Boys
  • Low ( 125 mg) and high dose (1000 mg) 7-week DBPC
    clinical trial
  • Sample 70 boys consented, 61 completed 3 month
    protocol (7 weeks on medication) 58 had all
    outcome measures
  • Multi-method, Multi-trait measures
  • CGI-I Intent-to-treat 35 responded (53 in
    high dose vs. 8 in low dose condition)
  • Significant differences in self rated slopes of
    weekly restraint
  • No significant side effects (drowsiness, GI
    upset), easily tolerated

Steiner, 2002
23
Different Patterns of Aggression Respond to
Divalproex Sodium
  • 61 adolescent males into predominantly High
    Distress (HDCD) and Low Distress (LDCD) Conduct
    Disorders
  • Low distress CD show predominantly premeditated
    aggression High Distress CD are predominantly
    RAD aggressive.
  • In a 7 week RDBPC trial of DVPX we found that the
    HDCD had a more robust response to therapeutic
    doses of DVPX Sodium
  • Responsive targets were observer rated CGI,
    weekly slopes of self reported Distress
    (decreased) and Restraint (increased)

Implications of DBPC trials in CD 2002Emerging
Pathways
  • Lithium may be most applicable in prepubertal
    aggression with a reactive/affective/defensive
    profile
  • Divalproex may be most useful in pubertal CD with
    a high affective component either to mood
    disorder or trauma especially chronic trauma
  • Antipsychotics (risperidone haloperidol may be
    most helpful when executive cognitive functions
    are impaired (MR, PDD, psychosis)
  • Stimulants should be considered when there is a
    comorbid attention deficit (caveat juvenile
    bipolar)

Observing Infants Aggression at 1 Year Teen
Mothers and Researchers Reports
  • Sample of 60 teen mothers at high risk ,
    predominantly Hispanic, 33 boys and 28 girls
    followed from pre-birth, assessment at 13 months
  • Variables maternal psychopathology, CAPI, PSI
    Reported infant aggression, negative emotional
    reactivity and emotion regulation Same infant
    variables observed
  • Experimental tasks strange situation, Bailey
    testing

Gschwendt, Zelenko Steiner, 2002
32
Observing Infants Aggression at 1 year Results
  • In infants, negative affective reactivity,
    emotion regulation and aggression were
    significantly correlated by mothers and
    observers reports, separately (Spearmans 0.47
    to - .81, ps lt 0.05)
  • Maternal depression, anxiety, CAPI and PSI
    correlated with mothers reports of infant
    aggression, negative affective reactivity
    (Spearmans 0.22 to 0.47, ps lt0.05) in infants
  • Mothers reports correlated with observer ratings
    only if their own functioning was taken into
    account

Trauma and Reactive/Affective/Defensive (RAD)
Aggression Summary APA 2002
  • Traumatic Events are extremely common in the
    lives of maladaptively aggressive (MAA) youth
  • PTSD is extremely common in MAA youth
  • PTSD leads to faulty primary appraisal,
    anxious/angry activation and loss of self
    restraint reactive/affective/defensive
    aggression kindling
  • Treatment with DVPX is effective in CD, even more
    effective in CD and PTSD
  • Antikindling treatment seems to treat
    reactive/affective/defensive aggression good
    response is predicted by variables related to
    PTSD at baseline
  • Early antecedents of reactive/affective/defensive
    aggression involve negative affect/ poor emotion
    regulation and aggression in the infant (by both
    observer and mothers reports and increased
    attribution of negative characteristics by the
    mother as a function of her anxiety and depression
