Reliability and validity of the Turkish version of the Diabetes Distress Scale for type 2 diabetes and distress levels of the participants

Background/aim: Studies have shown an increased depression rate in patients with type 2 diabetes mellitus (T2DM) compared to thenormal population. It is now acknowledged that patients suffer from distress rather than depression. Our aim was to validate the Turkishversion of the Diabetes Distress Scale (DDS) and to show distress levels of the participants.Materials and methods: The scale was translated from English to Turkish by the authors and translated back to English. BetweenAugust 2015 and January 2016 all the patients who were referred to the T2DM Clinic of İstanbul Medeniyet University were screened,and eligible patients were recruited. For calculating internal consistency Cronbach’s alpha coefficient was used.Results: A total of 205 patients [120 females (58.5%), 85 males (41.5%)] were included. Cronbach’s alpha coefficient was 0.874, showinginternal consistency. The Spearman Brown correlation coefficient was calculated between the first 9 and second 8 questions as 0.884.Thetotal variances were explained at a level of 66.2% with 4 factors. Sixty-three patients (30%) had a score of ≥3, indicating diabeticdistress. Correlation analysis showed a significant correlation between total score and HbA1c levels (r = 0.152 and P = 0.038).Conclusion: The Turkish version of the DDS for type 2 diabetes is a reliable tool for assessment of distress levels.
