Two studies assessed school-aged children's reactivity to parental conflict simulations and adolescents' reactions to actual marital conflict. Three profiles of reactions were identified: secure children, insecure-preoccupied children, and insecure- dismissing children. Findings in both studies indicated that preoccupied children evidenced the highest levels of internalizing symptoms. In Study 2, dismissing adolescents reported more coping, family, and personality difficulties than did secure adolescents. (Author/KB)
