Abstract

Objective: The aim of this study was to test the validity and reliability of the Turkish version of the diabetes quality of life (DQOL) questionnaire for use with patients with diabetes.

Methods: Turkish version of the generic quality of life (QoL) scale 15D and DQOL, socio-demographics and clinical parameter characteristics were administered to 150 patients with type 2 diabetes. Study participants were randomly sampled from the Endocrinology and Diabetes Outpatient Department of Dr. Lutfi Kirdar Kartal Education and Research Hospital in Istanbul, Turkey.

Results: The Cronbach alpha coefficient of the overall DQOL scale was 0.89; the Cronbach alpha coefficient ranged from 0.80 to 0.94 for subscales. Distress, discomfort and its symptoms, depression, mobility, usual activities, and vitality on the 15 D scale had statistically significant correlations with social/vocational worry and diabetes-related worry on the DQOL scale indicating good convergent validity. Factor analysis identified four subscales: satisfaction", impact", "diabetes-related worry", and "social/vocational worry".

Conclusion: Statistical analyses showed that the Turkish version of the DQOL is a valid and reliable instrument to measure disease related QoL in patients with diabetes. It is a simple and quick screening tool with about 15 +/- 5.8 min administration time for measuring QoL in this population.
