title: Self-reported symptoms of depressed mood, trait anxiety and aggressive behavior in post-pubertal adolescents: Associations with diurnal cortisol profiles.
abstract: The association between self-reported symptoms and diurnal cortisol profiles was studied in post-puberty adolescents (29 boys and 29 girls, M(age)=15.06 years). The adolescents completed the Children's Depression Inventory, State Trait Anxiety Inventory, and an Aggressive behavior scale. The diurnal cortisol profile was derived from three saliva samples, collected at awakening, noon and evening on a week-end day. Univariate repeated measurement regressions revealed that depressed mood and trait anxiety were strongly and aggressive behavior was weakly related to the diurnal cortisol profile: greater emotional distress was associated with flatter diurnal cortisol profiles. Multivariate analysis, however, revealed that only trait anxiety made an independent contribution. Further analyses suggested that trait anxiety was related to elevated evening cortisol rather than to decreased awakening cortisol and that from a trait anxiety score of 38 onwards, high anxious adolescents show clearly higher evening cortisol than low anxious adolescents. These data suggest that anxiety disorder co-morbidity might explain some of the differences in HPA-axis function among depressed patients.
