Meta-analytic connections between forgiveness and health: the moderating effects of forgiveness-related distinctions.

OBJECTIVE: We explore meta-analytic associations between health and forgiveness, testing a number of potential theoretical and methodological factors that could alter that association, including the type of forgiveness measure (e.g. state vs. trait), the type of health measure (i.e. physical vs. psychological) and the target of forgiveness (e.g. self- vs. other-forgiveness).

DESIGN: Our findings below reflect the meta-analysis of 103 independent samples consisting of 606 correlations with a total sample of 26,043 participants. The final sample included papers from 17 countries. The included samples were diverse including students, older adults, divorced mothers, combat veterans and others.

MAIN OUTCOME MEASURES: Various health measures, including physical health outcomes (e.g., blood pressure, cortisol levels, bodily pain) and psychological health outcomes (e.g., depression, anxiety, PTSD).

RESULTS: We found a reliable overall association between forgiveness and health outcomes. The association was stronger for psychological health than for physical health, though associations with cardiovascular health indicators (i.e. heart-rate and blood pressure) were robust.

CONCLUSION: The findings provided considerable support to current theorizing about the health benefits of forgiveness. It is plausible that forgiveness might improve psychological health and reduce cardiovascular stress.
