Some researchers also worry that forgiveness interventions will promote unhealthy relationships. They worry that individuals with toxic relationships will continue to forgive those who continuously commit wrong acts towards them when in fact they should be distancing themselves from these sorts of people. A number of studies showcase high effectiveness rates of forgiveness interventions when done continuously over a long period of time. Some researchers have found that these interventions have been proven ineffective when done over short spans of time. There has been some research within the last decade outlining some studies that have looked at the effectiveness of forgiveness interventions on young children. There have also been several studies done studying this cross culturally. One study that explored this relationship, was a study conducted in 2009 by Eadaoin Hui and Tat Sing Chau. In this study, Hui and Chau looked at the relationship between forgiveness interventions and Chinese children who were less likely to forgive those who had wronged them. The findings of this study showed that there was an effect of forgiveness interventions on the young Chinese children. Survey data from 2000 showed that 61% of participants that were part of a small religious group reported that the group helped them be more forgiving. Individuals reported that their religion groups which promote forgiveness was related to self-reports of success in overcoming addictions, guilt, and perceiving encouragement when feeling discouraged. It is suggested that mindfulness plays a role in forgiveness and health. The forgiveness of others has a positive effect on physical health when it is combined with mindfulness but evidence shows that forgiveness only effects health as a function of mindfulness. A study from 2005 states that self-forgiveness is an important part of self-acceptance and mental health in later life. The inability to self-forgive can compromise mental health. For some elderly people, self-forgiveness requires reflecting on a transgression to avoid repeating wrongdoings, individuals seek to learn from these transgressions in order to improve their real self-schemas. When individuals are successful at learning from these transgressions, they may experience improved mental health. A study in 2015 looks at how self-forgiveness can reduce feelings of guilt and shame associated with hypersexual behaviour. Hypersexual behaviour can have negative effects on individuals by causing distress and life problems. Self-forgiveness may be a component that can help individuals reduce hypersexual negative behaviours that cause problems. Evidence shows that self-forgiveness and procrastination may be associated; self-forgiveness allows the individual to overcome the negatives associated with an earlier behaviour and engage in approach-oriented behaviours on a similar task.
