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.
