Adaptation and Standardisation of Individual Work Performance Questionnaire among Public Sector Undertaking Employees in India

Accurate measurement of individual work performance is fundamental to organisational research and human resource management. The Individual work performance questionnaire was designed by Linda Koopman et., al in 2014. It is used to judge the job performance of an individual across 3-dimensions; Task performance, Contextual performance and Counter-productive work behaviour. This study aimed to adapt and validate the Individual Work Performance Questionnaire (IWPQ) for use among employees in the Indian public-sector undertakings (PSU). The questionnaire was culturally adapted following established translation and adaptation procedures to ensure linguistic and contextual relevance. Data were collected from 219 employees comprising executives and workmen from a large PSU. Content validity was established through expert evaluation of the adapted items. Reliability analysis demonstrated satisfactory internal consistency across the three dimensions of work performance. Construct validity was examined through factor-analytic procedures, supporting the multidimensional structure of the instrument. The adapted scale retained the dimensions of Task Performance, Contextual Performance, and Counterproductive Work Behaviour. The findings indicated that the adapted IWPQ possesses acceptable psychometric properties for assessing employee performance in the Indian PSU context. The instrument provides researchers and practitioners with a reliable and valid measure of individual work performance. The study contributes to the cross-cultural validation of performance assessment tools and supports their application in organizational research and practice.
