Assessing the Turkish version of the Individual Work Performance Questionnaire (IWPQ) for its validity and reliability

Abstract

Abstract Backgrounds This study aimed to assess the validity and reliability of the Turkish version of the Individual Work Performance Questionnaire (IWPQ). Methods A total of 340 adult participants who had been working for at least 8 h a day completed the study questionnaire online. The questionnaire consisted of sections on demographics and socioeconomic characteristics, the IWPQ, and the ultrashortened version of the Utrecht Work Engagement Scale (UWES-3). Principal component analysis (PCA) with Promax rotation was conducted to assess the e three-factor structure for the Turkish version of the IWPQ. Cronbach’s alpha was used to determine internal consistency. The intraclass correlation coefficient (ICC) was used to assess test-retest reliability. Spearman correlation coefficients were calculated between the IWPQ and UWES-3 scales to evaluate convergent validity. Results The three factors accounted for a total variance ratio of 60.7%. Cronbach’s alphas of three subscales (task performance, contextual performance, and counterproductive work behavior) were 0.894, 0.875, and 0.796, respectively. Test-retest reliability showed high agreement, with ICCs of 0.96, 0.98, and 0.91 for the respective scales. There was a statistically significant correlation between UWES-3 and the task performance subscale (ρ = 0.367 and p < 0.001), a statistically significant correlation between UWES-3 and the contextual performance subscale (ρ = 0.403 and p < 0.001), and a statistically significant correlation between UWES-3 and the CWB subscale (ρ=-0.352 and p < 0.001). Conclusions The Individual Work Performance Questionnaire (IWPQ) identifies work performance.The Turkish version of the IWPQ scales demonstrated validity and reliability in assessing individual work performance.
