Children's Perception of Interparental Conflict Scale (CPIC): factor structure and invariance across adolescents and emerging adults

Abstract

The Children's Perception of Interparental Conflict Scale (CPIC) is based on the cognitive-contextual framework for understanding interparental conflict. This study investigates the factor validity and the invariance of two factor models of CPIC within a sample of Portuguese adolescents and emerging adults (14 to 25 years old; N = 677). At the subscale level, invariance analyses (configural and metric) showed that the three-factor model with seven subscales operated equivalently across adolescents and emerging adults, although non invariant intercepts emerged when testing scalar invariance. Confirmatory factor analyses (at the item and subscale level) and follow-up model fit indices supported the theory-based factor structure of the CPIC's original model. (c) Taylor & Francis Group, LLC.
