Validation of the Brazilian version of the World Health Organization Disability Assessment Schedule in individuals with diabetes mellitus

Abstract

To evaluate the functioning of individuals with diabetes mellitus (DM) using a biopsychosocial model, recommended by the World Health Organization and sustained in the theoretical-conceptual framework of the International Classification of Functioning, Disability and Health (ICF), this study proposed validating the Brazilian version of WHODAS 2.0 (World Health Organization Disability Assessment Schedule). The 36-item version of WHODAS 2.0 was applied to 100 participants with DM as validation procedures, using the measurement of Diabetes Quality of Life Measure (DQOL-Brazil) and a dynamometry. The psychometric properties analyzed were internal consistency (Cronbach Alpha coefficient) and convergent and divergent external validity (Spearman correlation coefficient). The internal consistency analysis was appropriate, except for the “having a good relationship with people” domain in the alpha Cronbach coefficient. External validity analysis confirmed the convergence hypothesis between the correlate domains of the different tools. The exception was the “life activities” domain (WHODAS) with the left-hand dynamometry. The Brazilian version of the WHODAS 2.0 instrument is a valid instrument to assess the functioning of these individuals.

Disability assessment of individuals with diabetes mellitus: a cross-sectional study with the WHODAS 2.0

“…Reported disability was considered a variable and, for its measurement, the Brazilian version of the WHODAS 2.0 with 36 items was used (applied by an interviewer or self-applied) 18 . All questions concern difficulties faced by individuals in six life domains during the 30 days before application of the questionnaire.…”

“…To measure functioning and disability, the World Health Organization (WHO) developed, based on ICF items 15 , the World Health Organization Disability Assessment Schedule version 2.0 (WHODAS 2.0) to measure disability in a cross-cultural way. This tool has already been validated for individuals with HIV/AIDS 16 , institutionalized older adults 17 , and individuals with DM 18 , blindness 19 , and temporomandibular disorder 20 .…”

Avaliação da incapacidade de indivíduos com diabetes mellitus: um estudo transversal com o WHODAS 2.0

“…Considerou-se como variável a incapacidade relatada e, para sua mensuração, foi utilizada a versão brasileira do WHODAS 2.0 com 36 itens (administrada por entrevistador ou autoadministrada) 18 . As perguntas dizem respeito às dificuldades enfrentadas pelos pacientes em seis domínios da vida durante os últimos 30 dias.…”

“…Para medir a funcionalidade e incapacidade, a Organização Mundial da Saúde (OMS) desenvolveu, a partir de itens da CIF 15 , o World Health Organization Disability Assessment Schedule versão 2.0 (WHODAS 2.0) para mensurar a incapacidade de modo transcultural. Este instrumento já foi validado para indivíduos com HIV/Aids 16 , idosos institucionalizados 17 e pacientes com DM 18 , cegueira 19 e disfunção temporomandibular 20 .…”
