Psychometric evaluation of the german version of the parent-adolescent communication scale

Abstract

AbstractThe quality of dyadic Parent–Child Communication (PCC) between parents and their adolescent children may be important for the adolescent’s general development and mental health during adolescence. Since German instruments for measuring PCC are still lacking, this study aimed to validate the German translation of the Parent-Adolescent Communication Scale (PACS), an internationally established self-report questionnaire. To examine the theoretical-based two-factor model of the PACS in a German population sample of 1044 parent-adolescent dyads, confirmatory factor analyses were used. Moreover, the cross-group measurement invariance of the instrument was assessed. Two clinical samples were used to assess discriminative validity. Bland–Altman plots were used to asses parent-adolescent agreement. The two-factor structure of the PACS was supported. Scalar measurement invariance was established for parent age groups and adolescent gender but not for adolescent age groups and parent gender. Convergent and divergent validity were established. Discriminative validity was only established for the adolescent version in the adolescent psychiatry sample. Test–retest reliability was satisfactory, and rater agreement was medium. The German translation of the PACS is a reliable and valid measurement to assess parent-adolescent communication quality per self-report. Research directions include the concordance discrepancy in clinical samples and further investigation of changes in parents’ and adolescents’ perspectives on communication problems and open communication.
