What makes life purposeful? Identifying the antecedents of a sense of purpose in life using a lagged exposure-wide approach.

AIMS

Prior research documents strong associations between an increased sense of in life and improved health and well-being outcomes. However, less is known about candidate antecedents that lead to more purpose among older adults.

METHODS

We used data from 13,771 participants in the Health and Retirement Study (HRS) - a diverse, national panel study of adults aged >50 in the United States, to evaluate a large number of candidate predictors of purpose. Specifically, using linear regression with a , we evaluated if in 61 predictors spanning physical health, health behaviors, and psychosocial well-being (between t;2006/2008 and t;2010/2012) were associated with purpose four years later (t;2014/2016) after adjustment for a rich set of baseline covariates.

RESULTS

Some health behaviors (e.g., physical activity ≥1x/week [β = 0.14, 95% : 0.09, 0.19]), physical health conditions (e.g., stroke [β = -0.25, 95% : -0.40, -0.10]), and psychosocial factors (e.g., depression [β = -0.21, 95% : -0.27, -0.15]) were associated with subsequent purpose four years later. However, there was little evidence that other health behaviors, physical health conditions, and psychosocial factors such as smoking, drinking, or financial strain, were associated with subsequent purpose.

CONCLUSIONS

Several of our candidate predictors such as volunteering, time with friends, and physical activity may be important targets for interventions and policies aiming to increase purpose among older adults. However, some effect sizes were modest and contrast with prior work on younger populations, suggesting purpose may be more easily formed earlier in life.
