The present cross-sectional study aimed to examine whether characteristics of the parent-child relationship in adolescence are important for adjustment and identity development. Participants were recruited from schools in central Sweden for a larger longitudinal study when the cohort was 13- to 14-year-olds (N = 3,667). Characteristics of the parent-child relationship, like parental warmth, democratic parenting, and child communication, and adolescent adjustment problems and identity coherence were studied. It was found that democratic parenting was positively linked to child communication but negatively associated with problematic peer relationships and behavioral problems. Parental warmth was linked to other parenting characteristics as well as identity cohesion. Democratic parenting was linked to greater school engagement and identity coherence for boys and girls. Gender differences were found. The findings support the notion that democratic and warm parenting may provide support for adolescent identity development and adjustment.
