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.

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 1st grade. Inexpressive preschoolers appeared to have more depressed and anxious symptoms at follow-up.

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.

Behavioral responses to stress and challenge are based in emotional and physiological arousal reactions. Adolescents with maladaptive or problematic behavior patterns, such as internalizing or externalizing problems, are likely to show atypical emotional and physiological reactions to stress. Relations between problems and reactions to stress were examined in a sample of 55 young adolescents with normal to clinical levels of internalizing and externalizing problems. Youth had their self-reported emotional states, heart rate, and blood pressure levels measured before and after engaging in two socially challenging, evaluative manipulations. Internalizing problems were associated with less positive affect but greater anxiety and cardiovascular arousal, whereas externalizing problems predicted greater hostility and positive affect but less cardiovascular arousal. The necessity of recognizing and incorporating comorbid characteristics and multiple response systems into studies of the links between problems and reactivity is emphasized in the discussion.

We investigated narratives, symbolic play, and emotions in children who varied in severity of disruptive behavior problems. Childrens representations of hypothetical situations of conflict and distress were assessed at 4-5 and 7 years. Behavior problems also were assessed then and again at 9 years. Childrens aggressive and caring themes differentiated nonproblem children, children whose problems remained or worsened with age, and those whose problems improved over time. Differences in boys and girls whose problems continued sometimes reflected exaggerations of prototypic gender differences seen across the groups. Boys with problems showed more hostile themes (physical aggression and anger), whereas girls with problems showed more caring (prosocial) themes relative to the other groups. Modulated (verbal) aggression, more common in girls than boys, showed developmentally appropriate increases with age. However, this was true only for children without problems and those whose problems improved. We consider how these findings contribute to an understanding the inner worlds of boys and girls who differ in their early developmental trajectories for behavior problems.

BACKGROUND Effective emotion regulation should be reflected in greater coherence between physiological and subjective aspects of emotional responses. METHOD Youths with normative to clinical levels of internalizing problems (IP) and externalizing problems (EP) watched emotionally evocative film-clips while having heart rate (HR) recorded, and reported subjective feelings. RESULTS Hierarchical linear modeling revealed weaker coherence between HR and negative feelings in youths, especially boys, with more EP. Youths with IP showed coherence between HR and negative feelings that did not match the affect portrayed in the eliciting stimuli, but atypical positive emotions: they felt happier when they had slower HR. Youths without problems predominantly showed normative emotional coherence. CONCLUSIONS Youths with EP and IP experience atypical patterns of activation across physiological and experiential emotion systems which could undermine emotion regulation in evocative situations.
