Family relationships form very important social relationships. They provide the social context enabling the development for a healthy personality and fostering social competencies and the capacity for social adjustment. Several constructs constitute a complex sample of health beneficial attributes, such as resilience, sense of coherence, self-compassion and others, that haven't been investigated in connection with perceived quality of family relationships and collective family efficacy. In three studies we investigated, if perceived quality of family relationshipsassessed with a relatively new measure: the Evaluation of Social Systems Scalewas associated with these advantageous health-related qualities, additionally confirming EVOS' construct validity. In study 1 (N = 207) and 2 (N = 305) university students filled out several paper-pencil-questionnaire whereas in study 3 (N = 528) a heterogeneous sample took part in an online-survey. Controlling for participants' age and sex, better family relationships were associated with reduced psychological distress (r = −.30 to −.37), more satisfaction with life (r = 0.40), stronger resilience (r = 0.37), sense of coherence (r = 0.37), self-compassion (r = 0.33), optimism (r = 0.32), general self-efficacy (r = 0.27), and self-esteem (r = 0.34). Results highlight the importance of the family environment not only for psychological health and quality of life, but also for individual adaptation and well-being. In future research, this should be especially addressed in designing and providing preventative interventions for families.
