People Performance Scales (PPS): A multi-company, cross-sectional psychometric assessment.

This study aims to test the nomological validity of the People Performance Scales (PPS) using the job demands-resources (JD-R) model. 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 2,469 respondents completed the questionnaire, resulting in an 87 percent response rate.
