Abstract
The Individual Work Performance Questionnaire (IWPQ) can be defined as the individual be-haviour capable of generating value and competitive advantage for the organization. It is a mul-ti-dimensional construct, consisting of task performance, contextual performance and counter-productive work behavior. Albeit important, a comprehensive measure of individual job per-formance is still lacking in the Italian context. This paper describes the validation of an Italian adaptation of the IWPQ. A back translation procedure was used. To investigate the psychometric properties of the 18-item Italian IWPQ, 1053 participants (502 men, 47.7%; 551 women, 52.3%) were enrolled; the age of participants ranged between 19 and 69 (Mage=34.6, SD= 11.8), and for the oc-cupation, the sample is classified in blue collar 32.5%, pink collar 33% and white collar 34.5%. Exploratory and confirmatory factor analyses and multigroup confirmatory factor analyses were performed to test the structural factor of the IWPQ. The results supported the goodness of the IWPQ in the Italian context and the scales were found consistent with the original structure. One item was omitted due to a low factor loading, resulting in a final 17-item structure. Multigroup confirmatory factor analysis showed that the factor solution was invariant across both gender and occupational category and found evidence of metric invariance, uniqueness and scalar invariance, and structural invariance. Convergent and discriminant validity were also tested and showed.
