Construct validity Regression analysis was used to examine unique and overall variance explained in Life Satisfaction (a single item scored 0-10). School Satisfaction (which was new to this child version) was found to explain unique variance beyond achievement, and unlike adult findings, safety was also found to explain unique variance while relationships did not. Overall variance of Life Satisfaction explained was 52%.
