We describe relationships between substance use, conduct disorder (CD), depression, and history of self-injury or suicide attempts, in referred, delinquent, substance involved, adolescent males. Sixty youths (mean age 16.3 years) completed standardized assessments for substance use and other psychiatric disorders, aggressiveness, and social class. All boys met modified criteria for CD. Most had high aggression ratings. Twenty percent had depressive diagnoses. By age 13, 78% had begun regular substance use. Marijuana was the first substance for 42%. The boys had substance dependence on a mean of 3.2 different drugs (usually including alcohol and marijuana), with abuse of an average of one additional drug. CD symptoms began 3.6 years (mean) before regular use. CD symptom count correlated with number of dependence diagnoses, and both of those (but not depression) related significantly to suicide attempt and self-injury histories. Improved understanding of substance involvement in youths with CD may generate more rational prevention and treatment.

Gilles de la Tourette syndrome (GTS), a chronic, familial, neuropsychiatric disorder of unknown etiology, is characterized clinically by the presence of motor and vocal tics that wax and wane in severity over time and by the occurrence of a variety of neurobehavioral disturbances including hyperactivity, self-mutilatory behavior, obsessive compulsive behavior, learning disabilities, and conduct disorder. Pharmacological studies suggest that the tics of GTS result from dysfunction of monoaminergic systems, more specifically from increased dopaminergic activity due to postsynaptic dopamine receptor supersensitivity. However, given that striatal dopaminergic and cholinergic systems exhibit reciprocal antagonism in other movement disorders such as Parkinsonism and chorea, it is conceivable that the cholinergic system is implicated in the disease. In the present communication it is proposed that: (a) the emergence of motor and vocal tics in GTS is associated with increased central cholinergic activity; (b) cholinergic overactivity is involved in the manifestation of other symptoms in GTS including depression, sleep disorders, motion sickness, pain, sensory tics, and the waxing and waning course of the disease; (c) abnormalities of the cholinergic system support previous evidence linking GTS with delayed cerebral maturation in a subset of young patients; and (d) drugs which stimulate cholinergic receptors may exacerbate symptoms of GTS, and as with dopamine agonists, should be avoided in patients with GTS.

The authors examined the siblings of 140 attention-deficit hyperactivity disorder (ADHD) and 120 control probands and classified families as antisocial if the proband had conduct disorder or a parent had antisocial personality. Partial support was found for the hypothesis that the ADHD gender effect would be limited to antisocial families. Boys had an increased risk for ADHD compared with girls, but only among siblings from antisocial families. The effect size for predicting ADHD in siblings of probands was greater for maternal compared with paternal ADHD, but only for families exhibiting antisocial disorders. Strong support was found for the hypothesis that, compared with siblings from nonantisocial families, those from antisocial families would have more psychopathology (ADHD, depression, substance use, and conduct disorders). The presence of antisocial disorders signals a distinct subtype of ADHD.

This study followed up into adulthood a group of child psychiatric patients suffering from depressive disorders and a closely matched nondepressed child psychiatric control group. Depression in childhood was a strong predictor of attempted suicide in adulthood. This predictive power was not due to the association between childhood depression and other childhood risk factors such as conduct disorder or suicidality. Rather, it seemed mostly to reside in the association between depression in childhood and major depression in adult life. These findings suggest that the pathways from childhood psychopathology to adult outcomes can be complex, and depend crucially on what happens later.

We examined 2-year recall of reports of lifetime symptomatology and substance use questions on the K-SADS-E in a sample of offspring at high and low risk for depression. Comparisons were made between those who forgot and those who remembered reports of screening symptoms made at the initial interview. In general, recall for symptoms of internalizing disorders (depression and anxiety disorder) was much worse than recall for symptoms of externalizing disorders (conduct disorder and substance use). Less than two-thirds of those initially meeting the lifetime depression screening criteria provided reports which met the lifetime screening criteria at followup. Significant correlates of screening criteria recall included the following variables (measured at the initial interview): history of treatment for any disorder, impairment on the GAS (a score less than 61), and the presence of hypersomnia and suicidal symptoms (thoughts or ideation). Logistic regression suggested that a prior report of suicidal symptoms (including thoughts, ideation, or behavior) was the most important correlate of screen recall.

Parent questionnaires from large Australian (N = 2093) and American (N = 500) clinic cohorts of adolescents were used to diagnose depression, attention deficit disorder with hyperactivity, and oppositional and conduct disorders. Co-occurrence of diagnoses was very high. Comorbidity between depression and conduct disorder was not higher than that expected for any psychiatric disorder (odds ratios = 1.20 and 1.45 respectively for each cohort) while comorbidity between attention deficit disorder with hyperactivity and oppositional disorder was higher than expected (odds ratios = 7.03 and 9.02) but comparable to that between conduct and oppositional disorder (odds ratios = 7.35 and 6.14). Co-occurrence of depression with other disorders did not increase the likelihood of comorbid conduct disorder.

The precise interrelationship between borderline personality disorder (BPD) and major depression (MD) remains unclear. To elucidate this further, we studied the characteristics of BPD in an unselected sample of 103 depressed subjects. All subjects were evaluated with structured diagnostic instruments. We contrasted three groups (MD plus BPD, MD plus a non-BPD, and MD plus no personality disorder) across several domains (characteristics of the depressive disorder, psychometric scales, axes I and II comorbidity, early environmental indices, family psychiatric history, and treatment response). Depressed subjects with BPD had significantly earlier onset of depression, dense axes I and II comorbidity, and higher prevalence of conduct disorder, and were characterized by elevated psychoticism and anger-hostility scores. In most other respects, however, depressed subjects with BPD were not strikingly distinct from other groups of depressed subjects.

An existing longitudinal data set was used to investigate the hypothesis that a depressive disorder in childhood increases the risk of an adolescent pregnancy. Depression is characterized by low self-esteem, lowered concern about one's personal welfare, passivity, and impaired motivation--all of which may prevent teenage girls from taking steps to protect themselves from pregnancy. The 83 subjects had been referred to a child psychiatric clinic (86%) or a general medical facility (12%) in Pittsburgh, Pennsylvania, between the ages of 8-13 years (average age at intake, 11.5 years). They underwent 4 clinical assessments in the first year of study participation and 2 assessments in each subsequent year. 65 girls experienced 1 or more DSM-III-R defined depressive episodes during the study period; the rest, who served as psychopathologic controls, had conduct disorders. 25 of the 83 subjects (30%, compared to the national average of 24%) had documented pregnancies by the age of 18 years. 28% of the pregnant teens had a history of early onset depression compared with 66% of their nonpregnant counterparts. On the other hand, 76% of the pregnant teens had been diagnosed with a conduct disorder by the age of 18 compared with 24% of the nonpregnant girls. Preliminary analysis further indicated that teenage pregnancy was associated with having been born out of wedlock or to a mother aged 18 years or younger; living in an intact family at time of study enrollment and socioeconomic status were not significant correlates. In the multivariate analysis, however, only two factors retained significance: a conduct disorder diagnosis in childhood (mean time to first pregnancy was 17.3 years compared to 18.7 years among remaining subjects) and race (Blacks tended to become pregnant by 17.4 years compared to an average of 18.7 years for Whites). No significant interaction was detected between a conduct disorder and race. These findings suggest that educational interventions aimed at decreasing impulsivity and undesirable consequences should be targeted at girls with conduct disorders.

There have been continuing concerns about the extent to which maternal depression may influence maternal reports of child behavior. To examine this issue, a series of structural equation models of the relationships between maternal depression and errors in maternal reports of child behavior was proposed and tested. These models assumed that (a) maternal depression was unrelated to maternal reporting behavior; (b) maternal depression causally influenced maternal reporting accuracy; (c) maternal depression was correlated with reporting accuracy. These models were fitted to data on maternal depression and multiple-informant (mother, teacher, child) reports of conduct disorder and attention deficit behaviors for a birth cohort of 12- and 13-year-old New Zealand children. The results of model fitting suggested the presence of small to moderate correlations (r = +.13 to +.40) between maternal depression and maternal reporting errors, indicating the presence of a tendency for increasing maternal depression to be associated with a tendency for mothers to over-report child behavior problems. However, independently of any effects of maternal depression on maternal reporting errors there was evidence of small but significant associations (r = .10 to .17; p < .05) between maternal depression and child conduct disorder and attention deficit behaviors.

Confirmatory factor analysis was used to support the dimensional structure of a four-factor retrospective measure of childhood behavior problems with a large, nonclinical adolescent sample. Acceptable levels of internal consistency and low-to-moderate levels of parent-adolescent interrater agreement were indicated for the four factors of attentional deficit/hyperactivity, oppositional behavior, conduct disorder symptoms and avoidance behaviors. The externalizing childhood problems (i.e., attentional deficit/hyperactivity, oppositional behavior, conduct disorder) were associated significantly with both internalizing (depression) and externalizing (e.g., alcohol consumption, delinquent activity) adolescent problem behaviors, as well as with an earlier age of onset for substance use. Avoidant behaviors in childhood were associated specifically with depressive symptomatology in adolescence. Results are discussed with regard to the role of childhood problems as precursors to adolescent/adult disorders.
