Measuring positive, psychological rewards: The validation of the Intrinsic Work Rewards Scale

Abstract

This study sought to validate the Intrinsic Work Rewards Scale (IWRS) using a transnational sample. Respondents were 486 non-profit employees from Australia, South Africa and the United States of America (females = 72.0%; managerial/ supervisory job level employees = 57.4%). Data analysis included reliability testing, exploratory and confirmatory factor analysis, and concurrent validity testing with established measures to which the IWRS is theoretically linked. The scores from the IWRS obtained an overall acceptable reliability coefficient of 0.86. Factor analysis confirmed its five factor structure, and correlations indicated that intrinsic rewards are positively related to work engagement, and negatively related to intention to quit. The IWRS appears to yield reliable scores for human resource managers advising in the non-profit employment sector.
