Forgiveness is considered a virtue by most people, and in today’s often-contentious society it can promote better relationships, better physical and mental health, and often better spirituality. People rarely present seeking treatment for forgiveness. Rather, it often surfaces as people deal with depression, anxiety, stress-related disorders, interpersonal anger, unforgiveness, couple and family conflict, self-condemnation, guilt, shame, and hopelessness. Treating issues in forgiveness is not tied to a particular treatment approach. Psychodynamic psychotherapists will find it particularly useful in family-of-origin issues. Cognitive-behavioral psychotherapists can incorporate most treatment protocols within their schema. One of the best ways to treat forgiveness issues is to use evidence-based treatments as adjuncts to psychotherapy (i.e., psychoeducational groups, workbooks, engagement with a faith community) and use psychotherapy to handle unresolved issues arising from adjunctive treatment. In this chapter, assessment, treatment, relevance for engaging other community resources like faith communities, and ethical issues are addressed.
