Title A comparative analysis of the work ability index
Bibliographic information Oct. 2010, Vol.60, No.7, p.517-524. Illus. 26 ref.
Abstract The Work Ability Index (WAI) is a well-established instrument to measure work ability. The objective of this study was to identify the dimensionality of the WAI and to investigate dependencies of factors and subscales. The sample analysed in this study consisted of 371 subjects of various occupational groups (teachers, office workers, nursery school teachers and managers). The WAI was measured for all subgroups. Psychometric characteristics of the WAI were investigated using factor analyses with different numbers and different patterns of dependency among the factors. Chi-square analysis and the Comparative Fit Index were used to statistically assess fit quality. Findings are discussed. It is concluded that using only the total score of the WAI is not adequate for population analysis and assessment of work ability. Instead, a two-dimensional structure must be taken into account.
