Abstract

Background

A self-reported Zung Self-Rating Depression Scale (ZSDS) is recognized as a reliable and valid measure for assessment of depressive symptoms, applicable cross-culturally. The aim of the study was to adapt ZSDS for application in the bilingual Azerbaijani population.

Methods

ZSDS was translated into Azerbaijani and Russian. Two pilot studies on small samples (n = 30 and n = 45) were conducted to improve the scale's acceptability. A readability study was conducted on a bigger sample of depressed subjects (n = 55) and healthy controls (n = 120). Chronbach's alpha for the total scale, item-test correlations, alpha if item deleted, and sensitivity and specificity at various cut-off levels were calculated.

Results

The drop-out rate was 83.3% at the first pilot study due to problems of comprehension of item 5 and culturally unacceptable wording of item 6. After rewording of the items drop-out reduced to 20%. On the reliability study Chronbach's alpha for the total scale was 0.8727, and item-test correlations for the most individual items were satisfactory. An optimal cut-off point was 45 points with sensitivity=90.91%, specificity=80.83%.

Conclusions

Adaptation of the Zung Self-Reported Depression Scale improved cultural acceptability of the scale in the context of the Azerbaijani study population.
