Abstract: (114 Views)
Introduction: Individual work performance (IWP) plays a crucial role in both organizational effectiveness and employee well-being. To address the limitations of existing job performance questionnaires, the Individual Work Performance Questionnaire (IWPQ) was developed based on a holistic and systematic framework. This study aimed to translate, culturally adapt, and evaluate the psychometric properties of the Persian/Farsi version of the IWPQ.
Material and Methods: This descriptive methodological study was conducted in two stages: (1) translation and cultural adaptation (assessment of face and content validity), and (2) psychometric evaluation (assessment of internal consistency, test-retest reliability, and construct validity). The sample consisted of 206 administrative employees with a mean age of 34.29 years (SD = 7.66) and an average work experience of 8.48 years (SD = 7.39). The IWPQ was translated using forward and backward translation methods, and its validity was evaluated using exploratory and confirmatory factor analyses.
Results: The Persian IWPQ demonstrated acceptable face and content validity. Exploratory factor analysis confirmed a three-factor structure: task performance, contextual performance, and counterproductive work behavior. Confirmatory factor analysis indices (e.g., CFI = 0.87, SRMR = 0.08 and RMSEA = 0.09) indicated a approached model fit acceptability. Internal consistency and test-retest reliability were satisfactory across all dimensions (Cronbach’s alpha > 0.70 and ICC > 0.80).
Conclusion: The Persian version of the IWPQ is a reliable and valid instrument for assessing individual work performance across diverse occupational groups. It provides a valuable resource for evaluating workplace interventions and strategies aimed at enhancing performance.
