A total of 421 adolescents with a mentally ill family member (target group) were compared to 9504 adolescents without familial mental illness (control group), using data from the Youth Health Monitor, conducted by the Dutch Public Health Service Gelderland North East (GGD GNE) based on ANCOVA and linear regression (n=9925; 51.4% girls; mean age=14.2). Results revealed that social support did not show group differences, but the target groups scored lower on assertiveness and parental relation quality. Moreover, parental relationship quality emerged as a positive moderator on adolescent psychosocial health. These findings highlight potential targets for future interventions aimed at enhancing parental relationships and assertiveness skills to improve the psychosocial health of adolescents with a mentally ill family member.Show less
