A validation study of the Hospital Anxiety and Depression Scale (HADS) in WLHIV

Résumé

Abstract Background Hospital Anxiety and Depression Scale (HADS) is a self-assessment tool that measures anxiety and depression and is mostly used in hospital settings. The purpose of this study is to test the validity and reliability of the Somali version of HADS in selected two hospitals in eastern Ethiopia. Method: From the WLHIV who attend the ART service, 357 women were included in the study and assessed with this tool. The English language of HADS was translated into the Somali version and used for this study. Statistical analysis was computed to examine the validity and measure the reliability of the study. Result This version of HADS was found to be acceptable for people living with HIV. To test the reliability, the internal consistency was found to be 0.83 for the anxiety sub-scale and 0.84 for the depression sub-scale. The Somali version of HADS has shown good internal consistency with its metric properties similar to international literature. By two-factor analysis, the Varimax rotation has shown high factor loading in both sub-scales (Anxiety and depression). Conclusion Therefore, this version can be used to screen the anxiety and depression of patients living with HIV. Therefore, the findings of this validation study show that the Somali version of the HADS is a valid and reliable tool to measure depression and anxiety and can be used to screen people living with HIV.
