Correlates and characteristics of adolescents' encoded emotional arousal during family conflict.

Associations between adolescents' range of fundamental frequency, cortisol output, and self-reported emotional experience were examined during problem discussions with parents. Participants are a community-based sample of 56 boys and girls in a longitudinal study on conflict exposure. Results reveal that higher aggregate levels of range of fundamental frequency are associated with higher cortisol output and higher levels of self-reported negative emotions for boys and girls. Additionally, greater cortisol output is significantly associated with a slower time-to-peak of range of fundamental frequency for girls and with significantly less variability in range of fundamental frequency for boys. Implications of results for emotional development in adolescents, measurement, and modeling are discussed.

Adolescents' cortisol reactivity and subjective distress in response to family conflict: the moderating role of internalizing symptoms.

PURPOSE: Internalizing symptoms have been associated with both higher and blunted cortisol responses in adolescents. Little attention has been paid to subjective experiences of distress in conjunction with internalizing symptoms in hypothalamic-pituitary-adrenal axis responses to laboratory stressors. The present study examines whether adolescents' internalizing symptoms moderate the association between cortisol responses and distress in response to a common stressor in adolescence: family conflict. Differences are also examined between adolescents with current, past only, and no history of internalizing symptoms. METHODS: Adolescents (N = 70) discussed areas of conflict with their parents and subsequently reported on distress experienced during the discussion. Baseline and five poststressor saliva samples were collected. Adolescents' internalizing symptoms were assessed concurrently with the discussion and at three previous time-points. RESULTS: Internalizing symptoms moderated the association between distress reported by the adolescents and cortisol reactivity in response to family conflict. Adolescents with current and past internalizing symptoms had a blunted cortisol response, whereas adolescents with no history of internalizing symptoms showed greater cortisol reactivity when reporting greater distress. CONCLUSIONS: This study expands the understanding of how current and remitted internalizing symptoms are related to adolescents' responses to everyday family conflicts. Adolescents with current and past internalizing symptoms demonstrated a lack of correspondence between psychological and physiological stress, whereas adolescents with no history of internalizing symptoms showed the anticipated correspondence. This study has important implications for understanding the link between internalizing symptoms and adolescents' hypothalamic-pituitary-adrenal functioning in response to common social stressors.

Interparental aggression and parent-adolescent salivary alpha amylase symmetry.

The present study examined salivary alpha amylase (sAA), a putative marker of adrenergic activity, in family members engaging in family conflict discussions. We examined symmetry among family members' sAA levels at baseline and in response to a conflict discussion. The relation between a history of interparental aggression on parent-adolescent sAA symmetry also was examined. Participants were 62 families with a mother, father, and biological child age 13-18 (n=29 girls). After engaging in a relaxation procedure, families participated in a 15-minute triadic family conflict discussion. Participants provided saliva samples at post-relaxation/pre-discussion, immediately post-discussion, and at 10 and 20 min post-discussion. Participants also reported on interparental physical aggression during the previous year. Across the sample we found evidence of symmetry between mothers' and adolescents' sAA levels at baseline and around the discussion. Interparental aggression was associated with lower sAA levels among fathers. Interparental aggression also affected patterns of parent-child sAA response symmetry such that families reporting interparental aggression exhibited greater father-adolescent sAA symmetry than did those with no reports of interparental aggression. Among families with no interparental aggression history, we found consistent mother-adolescent symmetry. These differences suggest different patterns of parent-adolescent physiological attunement among families with interparental aggression.

Youth exposed to violence: stability, co-occurrence, and context.

With considerable literature establishing how separate types of violence disrupt the lives of children, there is emerging interest in examining violence across multiple interpersonal domains. This article examines four commonly occurring and frequently researched domains of violence exposure: marital physical aggression, mother-to-youth aggression, father-to-youth aggression, and community violence. A community-based sample of 103 parents and youth provided three waves of data at annual intervals beginning when the youth were aged 9-10. We explored stability of exposure, co-occurrence across different types of violence exposure, and associations with co-occurring risk factors. Approximately 30-45% of youth reported intermittent exposure over the 3 years. In addition to overlap among types of violence exposure within the family, we found overlap between parent-to-youth aggression and community violence, an association that was exacerbated in families where fathers reported high levels of global distress symptoms. Mother-to-youth, father-to-youth, and community violence related to youth behavior problems beyond the contextual risk factors of low income, stressful life events, and parents' global distress symptoms. These results highlight the importance of examining violence longitudinally, across multiple types, and with attention to contextual factors.
