Abstract

World Health Organization (WHO) has developed WHO Disability Assessment Schedule (WHODAS 2.0) in line with International Classification of Functioning, Disability and Health (ICF) to assess disability across cultures and diseases. Universal usage of this instrument will synchronize disability data across various countries and help in international comparison. In this study, we sought to find out the cut-off point in WHODAS 2.0 12-item Interviewer Version that corresponds to the global score of 7 on Indian Disability Evaluation and Assessment Scale (IDEAS). This cut-off on IDEAS denotes 40 % disability, making patients eligible for social welfare benefits. Receiver operating characteristic (ROC) curve analysis showed that a score of 23 on WHODAS 2.0 12-item Interviewer Version corresponded to the global IDEAS score of 7 on using the Youden’s J static. Additionally, ROC curve showed that WHODAS is an accurate test to measure psychiatric disability.
