Verona, Edelyn Finy, M. Sima 2012-09-18T21:26:18Z 2012-09-18T21:26:18Z 2014-09-18T10:00:37Z 2012-08 2012-09-18T21:26:18Z 2012-08 Although the developmental period of adolescence is characterized by impulsive and risk-taking behaviors, explanations for the range of behavioral disinhibition across adolescents that include biological, personality, and environmental factors have not been fully elucidated. Additionally, these factors may affect changes in stress responses that occur during this period. To inform this area of research, we examined the interaction between psychosocial stress exposure and the personality traits of Negative Emotionality (NEM) and Constraint (CON) on behavioral disinhibition (as indexed by impulsivity and riskiness tasks) and salivary cortisol reactivity in a sample of 88 adolescents. Results demonstrated that NEM and CON were protective of impulsivity and riskiness, respectively, for adolescents in the no-stress condition. Importantly, low CON adolescents in the no-stress condition were more risky than low CON adolescents in the stress condition, while there was no effect of Stress Group for high CON adolescents. Further, low CON adolescents exposed to psychosocial stress exhibited greater cortisol reactivity compared to high CON adolescents, suggesting that individuals low in CON may mobilize greater resources (e.g., cortisol reactivity, cognitive control) in stressful relative to non-stressful situations. Results suggest that distinct facets of behavioral disinhibition are differentially affected by stress and personality traits in adolescents.
