Subjective Socioeconomic Status, Cognitive Abilities, and Personal Control: Associations With Health Behaviours
Overview
Affiliations
Objective: To examine subjective and objective socioeconomic status (SSES and OSES, respectively) as predictors, cognitive abilities as confounders, and personal control perceptions as mediators of health behaviours.
Design: A cross-sectional study including 197 participants aged 30-50 years, recruited from the crowd-working platform, Prolific.
Main Outcome Measure: The Good Health Practices Scale, a 16-item inventory of health behaviours.
Results: SSES was the most important predictor of health behaviours (beta = 0.19, < 0.01). Among the OSES indicators, education (beta = 0.16, < 0.05), but not income, predicted health behaviours. Intelligence ( = -0.16, < 0.05) and memory ( = -0.22, < 0.01) were negatively correlated with health-promoting behaviours, and the effect of memory was upheld in the multivariate model (beta = -0.17, < 0.05). Personal control perceptions (mastery and constraints) did not act as mediators.
Conclusion: SSES predicted health behaviours beyond OSES. The effect of socioeconomic indicators was not confounded by cognitive abilities. Surprisingly, cognitive abilities were negatively associated with health-promoting behaviours. Future research should emphasise SSES as a predictor of health behaviours. Delineating the psychological mechanisms linking SSES with health behaviours would be a valuable contribution toward improved understanding of socioeconomic disparities in health behaviours.
