In cross-cultural research on quality of life, researchers must deal with the fundamental incomparability of subjective wellbeing assessments across cultural groups. This incompatibility most probably results from an identification problem: cultural groups most likely differ in both objective achievements in different life domains as well as in the appraisal thereof. Information Integration Theory provides a framework that allows to better understand the composition of the concept of "satisfaction with life as a whole" across culturally different groups. In three web-based experiments, using Percentile Stimulus Metrics, it was studied how students in Algeria, Belgium and Poland integrate information on various life domains into an appraisal of satisfaction with life as a whole. It was found that different integration models coexist in the 3 studied groups, and that the prevalence of these strategies differs across groups. (Contains 4 figures, 2 footnotes, and 4 tables.)
