Aim: This study aims to test the nomological validity of the People Performance Scales (PPS) using the Job Demands-Resources (JD-R) model.
Materials and methods: All employees at two large companies in Norway (a governmental agency and a worker’s union) were invited to complete the PPS questionnaire electronically. A total of 2469 respondents completed the questionnaire, resulting in an 87 percent response rate. Data was analyzed Structural Equation Modelling.
Results: First, all 15 scales included in the PPS showed excellent internal and construct validity. PPS was also found to have configural-, construct-level metric- and scale-level metric invariance across age groups and genders. Second, findings indicate that the PPS can be used for both research and consultancy based upon the JD-R model, while simultaneously assessing constructs of particular importance in Norwegian and Scandinavian legislation.
Conclusion: The PPS represents a short and efficient questionnaire which measures the most relevant working environment constructs in a reliable and distinct way. The questionnaire has great psychometric characteristics and is well suited for use in organizations to measure employees´ experience of working environment factors, allowing organizations to identify areas of improvement and to support organizational development.
