The World Health Organization Disability Assessment Schedule (WHODAS 2.0) was designed to assess the functioning level in six life domains (cognition, mobility, self-care, getting along, life activities, and participation in community activities). It was used to measure functional impairment in cross-cultural studies. Universal usage of this instrument will synchronize disability data across various countries and help in international comparison.
To check the agreement in disability between WHODAS 2.0 (36-Item Version) and Indian Disability Evaluation and Assessment Scale (IDEAS) among Persons with Severe Mental Illness.
Materials and Methods:
This was a longitudinal study. A total of 60 participants were selected using a consecutive sampling procedure. Persons diagnosed with severe mental illness as per the ICD-10 diagnosis criteria, aged above 18 to 60 years with a total duration of illness of at least 2 years were considered for inclusion in the study. Patients and their primary caregivers who gave written informed consent were included in the study. Those who refused to consent to the research study and patients not staying with primary caregivers were excluded from the study.
There is a correlation between all the similar domains of WHODAS 2.0 and IDEAS. It is statistically significant except for the correlation between the “Mobility” domain of WHODAS 2.0 (36 items) and the “Communication and Understanding” domain of the IDEAS scale.
WHODAS 2.0 can be recommended either by itself instead of by IDEAS for the assessment of disability in the Indian setting as there is a highly significant agreement between WHODAS 2.0 with IDEAS. This will help the disability boards to give an exact percentage of disability; an aspect that was lacking in IDEAS where a range is available.
