Book excerpt: This volume collects the state-of-the-art research on forgiveness and mental and physical health and well-being. It focuses specifically on connections between forgiveness and its health and well-being benefits. Forgiveness has been examined from a variety of perspectives, including the moral, ethical and philosophical. Ways in which to become more forgiving and evolutionary theories of revenge and forgiveness have also been investigated and proposed. However, little attention has been paid to the benefits of forgiveness. This volume offers an examination of the theory, methods and research utilized in understanding these connections. It considers trait and state forgiveness, emotional and decisional forgiveness, and interventions to promote forgiveness, all with an eye toward the positive effects of forgiveness for a victim’s health and well-being. Finally, this volume considers key moderators such as gender, race, and age, as well as, explanatory mechanisms that might mediate links between forgiveness and key outcomes.
