• Orientation: The South African Occupational Health and Safety Act, Construction Regulations of 2003 has recently introduced the term psychological fitness. However, no definition or theoretical framework was provided to promote understanding of the term psychological fitness, and no measuring instrument exists to measure psychological fitness of blue collar workers. Research purpose: The objectives of this study were to propose a definition of psychological fitness, propose theoretical frameworks and develop and test the newly developed items of a measuring instrument, the South African Psychological Fitness Index (SAPFI) for work-related psychological fitness of blue-collar workers. Motivation for the study: Evidence exists that the work-related psychological well-being of white-collar workers has a profound effect on the individual, in terms of ill-health, as well as the organisation, in terms of productivity, turnover intention, commitment and safety. For this reason it is important to develop an instrument that measures the psychological well-being of blue-collar workers to understand how and if it will influence both their individual and organisational outcomes in the same way as for white-collar workers. Research design, approach and method: A cross-sectional survey design was used in a convenience sample of blue-collar workers in different industries in South Africa (N = 2769). Following scale development procedures, the SAPFI was developed measuring the psychological fitness of blue-collar workers. Main findings: Using Rasch analyses, three items were eliminated, resulting in a 23-item instrument. Five items were retained to measure exhaustion, five items to measure mental distance, five items to measure cognitive weariness, four items to measure vitality and four items to measure work devotion. Practical/Managerial implications: To adhere to legislation the SAPFI can be used by researchers and managers as a test of the work-related psychological fitness of blue-collar workers in South Africa. Contribution/Value-add: This study proposes a definition of and theoretical framework for work-related psychological fitness. This study provides a measuring instrument to evaluate the work-related psychological fitness states of blue-collar workers in South Africa and to provide companies with a scientific measurement tool to understand the work-related experiences of these workers.
