Background: Interventions that facilitate positive actions and attitudes seem to play an important role in enhancing psychological health. This study examines the effectiveness of two self-guided interventions with the aim to enhance adults' well-being through the cultivation of forgiveness skills. Methods: A total of 11 men and 31 women aged 34-80 years were involved (M = 56.57, S.D. = 13.44). All participants were Orthodox Christians, as the average Greeks are, without belonging to a closed religious community. They were asked to complete questionnaires that measure the sense of well-being, the trait of forgiveness, and avoidance, revenge, and benevolence motivation. Subsequently, they were randomly divided into two groups that corresponded to age, gender, and educational level. One group followed the General (n = 22), and the other one the Orthodox-Tradition-Enhanced Intervention (n = 20). The two interventions included six steps toward forgiveness. Self-paced sessions were implemented so as the interventions can be completed. On average, the process lasted two weeks.
