Objective: To investigate the impact of forgiveness interventions designed to help individuals who have suffered because of betrayals, offenses, or victimization. Forgiveness is believed to be a mechanism through which individuals can experience increases in hope and positive emotions and relief from negative emotions, cognitions, and behaviors. Method: Fourteen published reports of process-based forgiveness interventions that included a comparison group are meta-analyzed. Results/Conclusions: Samples that received forgiveness interventions forgave more (effect size [ES] = .82) and enjoyed increased positive affect (ES = .81) and self-esteem (ES = .60) and less negative affect (ES = .54). Such gains were largely maintained at follow-up periods. Individually delivered programs are superior to group delivery, and some forgiveness programs are superior to others. Further moderators are discussed.
