Health-related Quality of Life, Marital Satisfaction, and Social Support in Medical Staff in Iran

Quality of life is a subjective and multidimensional concept that includes all aspects of an individual's life. Many investigations indicate that marital satisfaction is an important determinant of quality of life and social support affects both marital satisfaction and quality of life. Since medical staff face job stressors in their everyday life, in the present cross-sectional study, the relationships between quality of life, marital satisfaction, and social support in medical staff in Tehran were analyzed. Data collection was performed in 653 medical staff using socio-demographic questions, the SF-36 questionnaire, the ENRICH Marital Satisfaction Inventory, and the Social Support Questionnaire. The results revealed that men reported significantly higher quality of life and marital satisfaction than women, but there was no gender difference in social support. The quality of life and marital satisfaction domains were found to be differentially correlated among male and female participants. All domains of marital satisfaction were found to be significantly associated with the "vitality" and "mental health" domains among females and "physical functioning" domain in the male. Also, social support was associated with almost all quality of life domains in both sexes. The multiple regression analyses indicated that all the study variables combined with socio-demographic factors can explain between 12 % and 28 % of the variance in quality of life domains. Therefore, focusing on these factors could be an effective approach to improve quality of life in medical staff as a group with a stressful job.
