Comparative Study
Reliability & validity of the Malayalam hospital anxiety & depression scale (HADS) in cancer patients.
The hospital anxiety and depression scale (HADS) has been widely used on cancer patients as an indicator of psychological morbidity. Though the scale has been used in India, no reports are available on translation of HADS in any Indian language and testing the reliability. The present study describes the translation process of HADS into Malayalam and testing its reliability and validity on psychological morbidity in cancer patients. ⋯ This preliminary validation study of the Malayalam version of the HADS showed it as an acceptable, and reliable measure of psychological morbidity among cancer patients. The prevalence of anxiety and depression in Indian population was low and enjoyment and anhedonia might present as anxiety initially.
