The main aim of the project was to investigate the predictors of positive work-related states and attitudes, e.g. work engagement, meaning at work and personal growth, and healthy organisations. A questionnaire on these positive factors at work were pilot-tested through a data collection in chosen companies in Norway and Sweden. The results of these studies were used as a base for a preliminary validation of the Nordic Questionnaire on Positive Organisational Psychology (N-POP) published in this report. It is concluded that the N-POP constitutes a reliable and valid instrument. The concluding summary suggests that the concepts of work environment, health and productivity do indeed seem able to flow together to reach an optimal point at which well-being at the individual level is coexistent with efficient and productive work organisations.
