Design/methodology/approach - After pilot-testing, the 47-item IWPQ was field-tested amongst a representative sample of 1,181 Dutch blue, pink, and white collar workers. Factor analysis was used to examine whether the four-dimensional conceptual framework could be confirmed. Rasch analysis was used to examine the functioning of the items in more detail. Finally, it was examined whether generic scales could be constructed. Findings - A generic, three-dimensional conceptual framework was identified, in which individual work performance consisted of task performance, contextual performance, and counterproductive work behavior. Generic, short scales could be constructed that fitted the Rasch model. Research implications – A generic, short questionnaire can be used to measure individual work performance across occupational sectors. In future versions of the IWPQ, more difficult items should be added to improve discriminative ability at the high ranges of the scale. Originality/value - This study shows that, using Rasch analysis, a generic and short questionnaire can be used to measure individual work performance.
