Quality of life is a major focus of health care today. In published studies on patients with type 2 diabetes, findings on quality of life are mixed. Those with diabetes have chronic illness and must adhere to a complicated care regimen daily, which for many patients is challenging. This study analyzed psychosocial factors and metabolic control as potential predictors of quality of life among these patients.
A cross-sectional study of 397 patients with type 2 diabetes was conducted in a hospital in Nanjing, China. Demographic information and clinical characteristics were collected from the medical record. The World Health Organization Quality of Life-BREF, General Self-Efficacy Scale, Diabetes Distress Scale, and Diabetes Empowerment Scale-Short Form were administered.
The mean score of quality of life was 67.80 ± 13.44 on a 100-point scale. General self-efficacy (β = 0.340, P < 0.001), diabetes distress (β = −0.266, P < 0.001), and diabetes empowerment ability (β = 0.207, P < 0.001) were predictors of quality of life. In contrast, other factors including HbA1c, diabetes complications, and the duration of diabetes were not associated with quality of life (P > 0.05).
Our study indicated that psychosocial factors such as self-efficacy, diabetes distress, and diabetes empowerment ability are related to quality of life. Assessment and interventions aimed at reducing psychosocial problems should be applied in diabetes care.
