Personal Wellbeing Index. Construct Validity for The Netherlands
This report describes the results of the analyses of the Personal Wellbeing Index (PWI) for the Netherlands. We show that the original scale has sufficient construct validity. Six of the eight distinguished life domains contribute significantly to the explained variance of the overall quality of life. Further, PWI indicators are related to other items and alternative dependent variables as expected from theory. Lastly, the eight life domains can be aggregated into one PWI scale with high constructvalidity. We conclude that the PWI can be used as a quality of life measure instead of a single life satisfaction indicator in order to reveal the multi-dimensionality ofquality of life.
