A study was conducted to examine the relationship between parents’ marital status and various dimensions of psychological well-being of adolescents in Greece. 166 adolescents from divorced and 166 from intact families completed a) the Achenbach’s Youth Self-Report Questionnaire, b) a questionnaire about their parents’ relationship and their own relationship with each one of their parents, and c) a questionnaire about demographics. The results showed that adolescents from divorced families had poorer academic performance and more internalizing and externalizing problems than their counterparts. Furthermore, it was found that a positive parent-child relationship was associated with the adolescents’ mental health. The parents’ relationship after divorce was also associated with the subjects’ mental health and more specifically with internalizing and externalizing problems.
