The forgiveness group became emotionally healthier than the control group after 14 months. Differences between the groups were observed for depression, anxiety, hope, and self-esteem. The results were maintained in a 14-month follow-up.
The forgiveness group became emotionally healthier than the control group, similar to the above study. The experimental participants need for drugs declined substantially, relative to the control group.
Again, the experimental (forgiveness) group became emotionally healthier than the control group. Cardiac disease often involves a tightening of the arteries, especially when people are angry. After experiencing forgiveness therapy, those in the experimental group exhibited better functioning arteries, meaning that patients have a reduced risk of chest pains and sudden death.
Results are similar to the above studies in terms of emotional health (decreased anxiety, depression, PTSD symptoms, and increased self-esteem).
Terminally-ill, elderly cancer patients
After a 4-week intervention, the forgiveness group showed greater improvement in psychological health (less anger, more hopefulness toward the future) than the control group.
Following treatment, participants demonstrated a significant gain in forgiveness and significant reductions in anxiety, anger, and grief as compared with controls.
Women with Fibromyalgia who were abused in childhood

Forgiveness Therapy in a Maximum-Security Correctional Institution
This first-of-its-kind randomized clinical trial in a maximum-security facility was completed earlier this year (2021) and showed strong statistical effects for those in the Forgiveness Therapy group compared to those in the control group.

Trial of a forgiveness intervention on acid attack victims in Pakistan

At-risk middle school students in Wisconsin
Those in the experimental group not only improved more in emotional health than those in the control group, but also improved more in academic achievement than the control counterparts.
At-risk female adolescents in Korea
This is one of Dr. Enright’s latest research reports which focuses on Korean students who have been bullied and who bully. Those in the experimental group not only improved more in emotional health than those in the control groups but also improved more in academic performance and in their behavior (less aggression and delinquency).
Primary grade students in Milwaukee, Wisconsin
Those in the experimental group were less angry than those in the control group.
Primary grade students in Belfast, Northern Ireland
Those in the experimental group were less angry and depressed and more forgiving than those in the control group.
Parents of students in Belfast, Northern Ireland
Parents in the test group improved statistically (the parents improved) as they taught forgiveness to their children.
Eighth Grade Students in an Urban Midwestern City
This 2014 study compares forgiveness education using pen-pal and journaling activities across two groups of socially and culturally diverse youth. The groups improved on both forgiveness and prejudice. The pattern of outcomes was different for the African American participants than for the European American participants.
Eighth Grade Students in Iran
This 2020 study investigated the effectiveness of a Forgiveness Education Program on reducing anger and ethnic prejudice and improving forgiveness in 224 eighth grade Iranian students in three provinces: Tehran, Eastern Azerbaijan, and Kurdistan. The experimental group was higher in forgiveness and lower in ethnic prejudice, state anger, trait anger, and anger ex-pression compared to the control group.
