Research in positive psychology has been focusing on ways to improve health and wellbeing of both clinical and non-clinical populations. The current paper is one of such studies that explore ways to improve wellbeing by examining the influence of family relationship and coping style on psychological wellbeing of undergraduates. Three hundred and fifty-two (352) undergraduates (52.8%, male and 47.2% female) drawn from the University of Nigeria, Nsukka participated in the study. Psychological Wellbeing Scale (PWBS), The Brief Family Relationship Scale (BFRS), and The Brief COPE were used for data collection. Pearson r and multiple hierarchical regression were used to examine the hypotheses. Result showed that family relationship and adaptive coping style significantly predicted psychological wellbeing. However, maladaptive coping did not predict. This study indicated that positive family relationship and adaptive coping style help to improve the psychological wellbeing of undergraduates. Unlike maladaptive coping style that is not a factor in the psychological wellbeing of undergraduates. In case of intervention, attention should be paid to family relationship and adaptive coping style.
