Adaptation and Validation of the Work Design Questionnaire for Angola

The purpose of this study was to adapt and gather evidence of validity for the Portuguese version of the Work Design Questionnaire (WDQ) in Angola. Initially composed of 77 items, the instrument was administered to 505 workers from different organizations. The data were submitted to exploratory factor analysis. The results revealed a structure of 15 factors (62 items) distributed among the four latent dimensions of work design, with adequate levels of convergent and discriminant validity. Cronbach’s alpha varies between 0.69 and 0.85. Possible interpretations of these relationships are discussed. As an additional support for the validity of the construct, differences between three occupational categories (administrative, managerial, and operational) were evaluated, with significant differences detected in 9 factors. It is concluded that the study provides evidence for the construct and divergent validity of a Portuguese version of the scale and presents an additional support for the generalization of the 15-factor structure to Angola.
