The authors' aim in the present study was to examine the effects of a brief forgiveness intervention for older adults. The psychoeducational group intervention consists of (a) established core components of previous forgiveness interventions and (b) additional components considering specific needs of older adults. Seventy-eight older adults (mean age 70.1 years) were randomized to a treatment condition or a waiting-list control condition. The intervention reduced the levels of perceived actual transgression painfulness, transgression-related emotions and cognitions, and negative affect. These findings suggest the promise of forgiveness interventions for older adults that help participants clarify and deal with past, present, and future interpersonal transgressions.
