Validade e confiabilidade da versão brasileira do Índice de Capacidade para o Trabalho

Abstract: OBJECTIVE:To evaluate the validity and reliability of the Portuguese language version of a work ability index. METHODS:Cross sectional survey of a sample of 475 workers from an electrical company in the state of Sao Paulo, Southeastern Brazil (spread across ten municipalities in the Campinas area), carried out in 2005. The following aspects of the Brazilian version of the Work Ability Index were evaluated: construct validity, using factorial exploratory analysis, and discriminant capacity, by comparing mean Wo… Show more

“…The question is part of the instrument "Índice de Capacidade para Trabalho" (ICT -Work Ability Index) 23 validated for Portuguese, 16 with substantial reliability for the present study (weighted kappa = 0.61; 95%CI 0.32;0.84). This variable was classifi ed into three categories of work absences: "no day" (reference category), "a few days" (≤ 9 days) and "many days" (≥ 10 days).…”

“…The work ability index was applied 16 , which portrays the worker’s own concept of his work ability. WAI was translated into Portuguese 16 and validated in Brazilian populations, showing satisfactory psychometric properties regarding construct validity, criterion, reliability 17 and test-retest reliability 18 . Its results can be used at individual and collective levels to identify workers with impaired functional capacity or to outline the capacity profile in a group of workers, respectively 19 .…”
