Purpose in life in adulthood and older adulthood: integrative review.

twenty-seven articles were selected, 22 of which were conducted under large prospective longitudinal studies, 3 were cross-sectional studies and 2 were experimental studies. The studies revealed robust associations between high PiL scores and lower risk of death, Alzheimer's disease, coronary and cerebrovascular diseases, disability, and sleep disorders; high PiL and positive outcomes in health, cognition, emotional regulation, subjective well-being, and sense of adjustment; PiL as a moderator or resilience resource between risks and adversities and good adaptation. These data are useful for research and intervention involving long-lived and vulnerable older persons.
