How many studies support Purpose in Life?

A dedicated meta-analysis found greater purpose in life is associated with lower all-cause mortality and fewer cardiovascular events, and this is corroborated by independent large cohort studies rather than resting on a single dataset: a UK Biobank analysis linked meaning in life to lower all-cause and cause-specific mortality, a US national cohort found life purpose predicted mortality in adults over 50, and an early landmark study found purpose in life predicted mortality among community-dwelling older persons. That's backed by 8 published studies in Vitaebase's database, including 1 meta-analysis, the most recent from 2025 -- a fairly substantial body of research for a single topic.
