Objective: Patients with type 2 diabetes mellitus often have depression or depressive symptoms, impaired family functioning and poor quality of life. This study aimed to examine relationships among psychological variables, including depressive symptoms, family functioning and quality of life, for Chinese patients with type 2 diabetes and to explore the influencing factors on quality of life for these patients. Method: In this cross-sectional study, 257 patients with type 2 diabetes and 259 nondiabetic community controls completed the Beck Depression Inventory, the Family Assessment Device, and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form. Results: Patients with type 2 diabetes reported significant family impairment in the dimension of affective involvement compared with nondiabetic community controls (p<0.05). Mean Family Assessment Device scores were negatively associated with quality of life scores among patients with type 2 diabetes. Age, depressive symptoms, duration of diabetes, communication, affective involvement and behavioural control were associated with quality of life in patients with type 2 diabetes. Conclusions: The results indicate that having type 2 diabetes was associated with some difficulties with family functioning and that poor family functioning was associated with a poorer quality of life. Additional factors, including older age, depressive symptoms, duration of diabetes, and some dimensions of family functioning, were found to be associated with quality of life in Chinese individuals with type 2 diabetes.
