The purpose of this study is to determine the relationship between family function and quality of life among university students. The method used is descriptive. The sample comprises 317 university students using random cluster sampling.The tools of data collection includes the Family Assessment Device (FAD) and the Quality of Life (SF-36) questionaire's.Collected data were analyzed by means of Pearson correlation coefficient, and stepwise regression analysis. The results show that there is a negative and reverse relationship between disorder in family function and quality of life (r=-0.381).There were also negative and reverse relationships between dysfunction in all components of family function (General function, problem solving, communication, roles, affective accompanying, behavior control, and affective closeness) and quality of life (r=-0.37, -0.27, -0.25, -0.32, -0.25, -0.33, -0.29 respectively). Also the results obtained from regression analysis indicate that about %14 of quality of life variance in students is determined by components of general function and behavior control. It is suggested that students’ quality of life may be enhanced by improving their family function via educational and counseling programs.
