Individuals routinely rate themselves higher than their peers on a number of attributes and capabilities, including their satisfaction with life. However, the construct validity of this above-average effect requires specific psychometric properties of ratings of one’s contentment and ratings of others’ perceived contentment. This article tests these propertieswith respect to the popular SatisfactionWith Life Scale through a multivariate measurement model with latent change andmethod effects. Themodel is fitted to two independent data sets (N =597 and N =964), and it is found twice that four items are suitable to compute ameaningful composite difference score. It is concluded that the above-average effect is a systematicmultivariate phenomenon that can be assessed by the difference of twomanifest, absolute evaluation scores.
