Objective

The aim of the study was to investigate the internal consistency and screening properties of the General Health Questionnaire-12 (GHQ-12) and the Hospital Anxiety and Depression Scale (HADS) in Turkish patients with leprosy.

 Method

The two screening instruments and a fully structured diagnostic interview (CIDI) were administered to 65 people drawn from all leprosy inpatient units in Turkey between March and June of 2001. The scales were evaluated using Cronbach’s alpha and Receiver Operating Characteristics (ROC) analyses. For each scale, criterion validity was assessed for any psychiatric disorder, depressive disorder and anxiety disorder.

 Results

The Cronbach alpha coefficients for the GHQ-12 and HADS were 0.84 and 0.81 respectively. For detecting any psychiatric disorder, the optimal cut-off for the GHQ-12 was 4/5 (sensitivity 0.82, specificity 0.62). The optimal cut-off for the HADS total score was 12/13 (sensitivity 0.80, specificity 0.77).

 Conclusion

The results indicate that the General Health Questionnaire-12 and Hospital Anxiety and Depression Scale have satisfactory internal consistency, and performed well to a similar extent for detecting psychiatric disorders in leprosy patients.
