The "Involution" Penalty: Why Objective Wealth Fails to Protect Mental Health Without Subjective Status Perception in China

BackgroundIn economically transitioning China, rising objective SES has coincided with increased depression prevalence. This study examines whether material accumulation is linked to greater psychological strain and how subjective status perception is associated with lower depression risk. MethodsWe analyzed a Chinese national sample (N = 19,049, PBICR2022). ObjectiveSES was constructed via PCA (income, education, employment, housing); subjective SES was measured on a 7-point scale. Depression was assessed using the PHQ-9 (cutoff [&ge;] 10). Bootstrapped mediation and Response Surface Analysis (RSA) mapped the topography of depression risk. ResultsObjective SES showed a positive total association with depression (c = 0.154, P < .001), but subjective status perception suppressed this association: higher objective SES predicted higher subjective status, which in turn predicted lower depression (indirect effect = -0.1086, 95% CI: [-0.127, -0.091]). RSA showed that depression risk was driven primarily by subjective rank rather than objective resources, with diminishing returns at higher levels. The indirect pathway was 2.75-fold stronger among never-married than married individuals and more pronounced among men, yet robust across geographic regions despite cross-provincial migration. LimitationsCross-sectional design precludes causal inference; subjective SES used a single-item measure, and common method variance cannot be fully excluded. ConclusionsMental well-being depends less on absolute resources and more on internalized social position. The inverse association of subjective status with depression is stable across regions but contingent on social anchors like marriage. Public health policy must address status anxiety among vulnerable groups, particularly unmarried men.
