A Within-Family Examination of Interparental Conflict, Cognitive Appraisals, and Adolescent Mood and Well-Being.

Interparental conflict (IPC) is a well-established risk factor across child and adolescent development. This study disentangled situational (within-family) and global (between-family) appraisal processes to better map hypothesized processes to adolescents' experiences in the family. This 21-day daily dairy study sampled 151 caregivers and their adolescents (61.5% female). Using multilevel mediation analyses indicated that, on days when IPC was elevated, adolescents experienced more threat and self-blame. In turn, when adolescents experienced more threat appraisals, they experienced diminished positive well-being; whereas days when adolescents felt more self-blame, they experienced increased negative mood and diminished positive well-being. Statistically significant indirect effects were found for threat as a mediator of IPC and positive outcomes. Daily blame appraisals mediated IPC and adolescent angry mood.
