Abstract

This research examines the replicability and generalizability of the association between purpose in life and grip strength. An individual-participant meta-analysis of 27 samples (total N=115,972) from 24 countries that spanned four continents (Asia, Europe, North and South America) with self-reported purpose in life and dynamometer-assessed grip strength.
