Insofar as forgiveness of oneself enables one to responsibly manage the consequences of wrongdoing, the practice of self-forgiveness may be essential to the preservation of one’s physical, psychological, relational, and spiritual health. In the present thesis, an intervention wait-list design was employed to investigate the efficacy of a 6-hour self-directed workbook designed to promote self-forgiveness. University students (N = 204) who reported perpetrating an interpersonal offense and who experienced some sense of remorse were randomly assigned to either an immediate treatment or wait-list control condition, and assessments were administered on three occasions. Participants’ self-forgiveness ratings increased in conjunction with completion of the workbook, and the effect of treatment depended upon self-administered dose and baseline levels of dispositional self-compassion in some cases. In summary, the workbook appeared to facilitate the process of responsible self-forgiveness among perpetrators of interpersonal wrongdoing, though replication trials are needed in which lower rates of attrition reduce the possibility of biased results
