What Does the MacArthur Scale of Subjective Social Status Measure? Separating Economic Circumstances and Social Status to Predict Health.

Abstract

Background: Subjective socioeconomic status is robustly associated with many measures of health and well-being. The MacArthur Scale of Subjective Social Status (i.e., the MacArthur ladder) is the most widely used measure of this construct, but it remains unclear what exactly the MacArthur ladder measures.

Purpose: The present research sought to explore the social and economic factors that underlie responses to the MacArthur ladder and its relationship to health.

Methods: We investigated this issue by examining the relationship between scores on the MacArthur ladder and measures of economic circumstances and noneconomic social status, as well as health and well-being measures, in healthy adults in the USA.

Results: In three studies (total N = 1,310) we found evidence that economic circumstances and social status are distinct constructs that have distinct associations with scores on the MacArthur ladder. We found that both factors exhibit distinct associations with measures of health and well-being and accounted for the association between the MacArthur ladder and each measure of health and well-being.

Conclusions: Our findings suggest that the MacArthur ladder's robust predictive validity may result from the fact that it measures two factors-economic circumstances and social status-that are each independently associated with health outcomes. These findings provide a novel perspective on the large body of literature that uses the MacArthur ladder and suggests health researchers should do more to disentangle the social and economic aspects of subjective socioeconomic status.
