- Abstract
Factors associated with the institutionalization of older adults may interfere with the Functioning of this population. There are few instruments that evaluate this component according to the biopsychosocial model. The World Health Organization Disability Assessment Schedule (WHODAS 2.0) is an instrument developed by WHO (World Health Organization) to measure functioning and disability supported by the theoretical-conceptual model of the International Classification of Functioning, Disability and Health (ICF). This study aims to verify the reliability, internal consistency (IC) and criterion validity of the Brazilian version of the WHODAS 2.0 when applied to institutionalized older adults with different health conditions. In total, 100 older adults participated in the study. IC was assessed by Cronbach's alpha. Spearman's coefficient was used to analyze test-retest reliability, with the WHODAS questionnaire being reapplied seven days after the first interview. Criterion validity (convergent and divergent) was also analyzed by Spearman's coefficient by the correlation analysis with the WHOQOL-BREF and the WHOQOL-OLD. As a result, we obtained an IC that was adequate for all domains (Cronbach's alpha =0.75), with strong test-retest reliability (r> 0.85). In the criterion validity, we obtained only moderate correlations of the WHODAS 2.0 domains with the WHOQOL-BREF and WHOQOL-OLD domains (r=-0.62; r=-0.61 respectively). The psychometric properties tested indicated reliability - good internal consistency and strong test-retest reliability - and qualifications correlations in the criterion value. These results demonstrated that WHODAS 2.0 is a valid and reliable instrument, thus providing an assessment tool for institutionalized older adults following the concepts and principles proposed by WHO for assessing functioning.
