Abstract
Introduction: Prevalence
of depression in patients with diabetes is 2-3 times more than patients without
diabetes. Hence, the aim of the current study was to evaluate the reliability
and validity of Persian version of the 10-item Kessler Scale (K10) in
assessment of mental health status among patients with type 2 diabetes in
Ardabil, Northwest of Iran.
Methods: This cross-sectional methodological study was
conducted in Ardabil on a total of 70 patients with type 2 diabetes. K10 was
translated into Persian by backward-forward method, and content validity was
evaluated by a panel of experts in the field of psychiatry, psychology and
epidemiology. Concurrent validity examined by the correlation between K10 and
general health questionnaire-12 (GHQ-12). The reliability and stability
evaluated by Cronbach¢s alpha and intraclass correlation coefficient
(ICC) (test-retest method). The total score was computed from 10-items, which
were classified into four categories (well, mild, moderate and severe). The
analysis was performed using SPSS the level of significance was set at 0.05.
Results: The total average content validity ratio (CVR) and
content validity index (CVI) were 0.88 and 0.95; correlation between K10 and
GHQ-12 was significant (r = 0.63, P < 0.001), hence, the content and
concurrent validity of K10 Persian version was confirmed. Reliability was
tested by Cronbach¢s alpha = 0.84 and ICC = 0.77, respectively.
Conclusion: The Persian version of K10 is valid and
reliable for evaluation of mental health status among patients with type 2
diabetes.
