The purpose of this study was to examine adrenocortical activity (basal, diurnal variation, and responses to social stressors) in adolescents at risk for psychopathology. Salivary cortisol levels were examined in normally developing and at-risk youth with internalizing and externalizing symptoms ranging from subclinical to clinical levels. Adolescents showed expected patterns of diurnal variation, with high early morning cortisol levels and a pattern of decline throughout the day. Females showed higher midday and late afternoon levels than males, and these patterns interacted with risk status. Internalizing problems sometimes were associated with gradual rather than steep declines in basal cortisol production. Both immediate and delayed cortisol reactivity to a social performance stressor were associated with internalizing symptoms. There was no evidence of relations between externalizing problems and underarousal of the hypothalamic–pituitary–adrenal (HPA) system. These and other results suggest that gender is an important moderating factor linking psychopathology, development, and context with HPA axis functioning in adolescence.

There is a paucity of research on how mothers and fathers socialize emotion in their adolescent sons and daughters. This study was based on 220 adolescents (range 11-to 16-years-old) who exhibit a range of emotional and behavioral problems and their parents. Parental responses to their children's displays of sadness, anger and fear were assessed. Mothers were found to be more engaged in their children's emotional lives than were fathers. With a few important exceptions (e.g., boys were punished for expressions of anger more than girls), adolescent girls and boys were socialized in much the same way. Parents of older adolescents were generally less supportive and more punitive toward emotional displays. Systematic links between adolescent problem status and parent approaches to emotion socialization were found. These findings on how parents socialize emotions in their adolescents have important implications for theory as well as practice.

The development of concern for others and externalizing problems were examined in young children with normative, subclinical, or clinical levels of behavior problems. There were no group differences in observable concern for others at 4-5 years of age. Children with clinical behavior problems decreased significantly in their concern by 6-7 years of age and were reported to have less concern at 6-7 years by mothers, teachers, and the children themselves, relative to other groups. Boys with clinical problems were more callous to others' distress at both time points. Girls showed more concern than boys across risk, time, and measures. Greater concern at 4-5 years predicted decreases in the stability and severity of externalizing problems by 6-7 years, and greater concern at 6-7 years predicted decreases in the stability of problems by 9-10 years. Finally, maternal socialization approaches predicted later concerned responding.

Emotion regulation (ER) was assessed during a negative mood induction in 79 preschoolers who varied in degree of behavior problems. Facial expressivity during the induction was used to identify 3 ER groups: inexpressive, modulated expressive, and highly expressive. Group differences in ER were significantly related to heart rate and skin conductance. Inexpressive preschoolers had the highest heart rate, lowest vagal tone, and smallest autonomic nervous system (ANS) change during the induction. Highly expressive preschoolers had the slowest heart rate, highest vagal tone, and largest ANS change. The inexpressive and highly expressive groups had more externalizing symptoms than the modulated group at preschool age and at follow-up at the end of 1 st grade. Inexpressive preschoolers appeared to have more depressed and anxious symptoms at follow-up.Disruptive behavior disorders are characterized by poor impulse control and violations of social standards of conduct during childhood. They are relatively stable (Barkley, 1990;Loeber, 1982;Olweus, 1979), resistant to treatment (Kazdin, 1987), and predictive of adult psychopathology (Robins, 1991). Disruptive behaviors, such as high levels of noncompliance and aggression, are identifiable as early as the preschool years (

Individual differences in salivary testosterone were examined in 213 adolescents (106 boys, 107 girls; mean age = 13.66 years) in relation to externalizing and internalizing psychopathology. Self- and parent-report measures of behavior problems and psychiatric symptoms were obtained. Latent anxiety–depression, disruptive behavior, and attention problem constructs were developed using multitrait, multimethod procedures. Saliva samples were collected in the morning, midday, and late afternoon on multiple days and were later assayed for testosterone. Latent constructs were derived for testosterone level and diurnal variation across the six sampling occasions. Structural equations modeled relationships between problem behavior and intra- and interindividual differences in testosterone separately by gender. For boys, lower levels of testosterone and testosterone levels that decreased more slowly across the day were related to higher levels of anxiety–depression and attention problems. These associations were not moderated by pubertal development. For girls, steep declines in testosterone production across the day related to higher levels of disruptive behavior problems, but this association was only evident after including pubertal development as a moderator in the model. These findings raise novel questions regarding the nature and magnitude of links between testosterone and problem behavior in youth.
