What was done
An individual-participant data meta-analysis evaluated 72 samples comprising 531,038 participants across six world regions. Each sample used linear regression to evaluate the relationship between purpose in life and concurrent depressive symptoms, adjusting for age, sex, race, ethnicity, and education. Results were pooled using random-effects meta-analysis. Additional analyses tested moderation by sociodemographic variables, odds of severe distress, and specific depressive symptoms (depressed affect and anhedonia).
What was found
A significant negative association between purpose in life and depressive symptoms was present in 71 of 72 samples (meta-analytic estimate = -0.32, 95% CI -0.35 to -0.30, p < 0.001). Heterogeneity was not explained by geographical, economic, or methodological factors. The association was slightly stronger in female and white participants compared to male and Black participants, but was otherwise consistent across age, ethnicity, and education. Each standard deviation increase in purpose was associated with lower odds of severe distress (meta-analytic OR = 0.53, 95% CI 0.50 to 0.57, p < 0.001; abstract text also states 'about 90 % lower likelihood'). Similar inverse associations were observed specifically for depressed affect (-0.33, 95% CI -0.40 to -0.26, p < 0.001) and anhedonia (-0.32, 95% CI -0.38 to -0.26, p < 0.001).
Why it matters
This large-scale global analysis demonstrates that the inverse relationship between purpose in life and depressive symptoms is highly robust and generalizable across diverse cultural, geographic, and economic contexts.
Limits
The analysis evaluated concurrent depressive symptoms, precluding causal or temporal inferences. Unmeasured residual confounding (such as physical health status, baseline psychiatric history, or current life stressors) could not be fully ruled out across all pooled datasets.
