This study aims to examine the effectiveness of implementing forgiveness therapy in enhancing the personal growth of inmates at the Tangerang Class II-A Women’s Correctional Facility. The method used was a pre-experimental study with a one-group pretest-posttest design. Nine subjects aged 20-40 years were selected from 50 inmates based on low to moderate scores on the forgiveness scale and the psychological well-being scale. The intervention consisted of six sessions adapted from the forgiveness model developed by Enright and Fitzgibbons. Data analysis utilized a paired-sample t-test and the N-Gain formula. The results showed a significant increase in personal growth scores from the pretest (M = 7.00; SD = 1.225) to the posttest (M = 9.44; SD = 1.424), with t(8) = −8.315 and p < 0.001. An N-Gain value of 0.610 indicates moderate effectiveness. The follow-up measurement (M = 9.67; SD = 1.118) did not differ significantly from the post-test (p = 0.347), indicating the sustainability of the changes achieved. Forgiveness scores also increased from 65.33 (pre-test) to 86.67 (post-test) and 87.33 (follow-up), confirming the role of forgiveness as a psychological mechanism for personal growth. These findings support the integration of structured forgiveness therapy into correctional programs for women’s prisons.
