Cortisol Reactivity, Distress Behavior, and Behavioral and Psychological Problems in Young Adolescents: A Longitudinal Perspective

Abstract

Cortisol levels, observed distress behavior, behavior problems, and symptoms of anxiety and depression are examined in young adolescents. The longitudinal design consists of three times of measurement, at 6-month intervals. We (1) examine covariations among cortisol level and extent of distress behavior in adolescents experiencing a challenging situation, (2) identify intraindividual patterns of change in cortisol level (cortisol reactivity) during the novel and challenging situation at the first time of measurement, (3) examine longitudinal changes in cortisol reactivity and distress behavior, and (4) examine relations between patterns of cortisol reactivity and behavior and psychological problems 1 year later. Significant decreases in distress behavior are found across the l-year period, whereas changes in cortisol level vary by gender. Cortisol level and extent of distress behavior are related under the most novel and challenging circumstance. Intraindividual differences in cortisol reactivity in the c...
