Equine-assisted psychotherapy (EAP) is a form of complementary treatment that involves interactions with horses. It is a collaborative effort between the participant, the therapist, and the equine specialist. This type of therapy has been used to treat a variety of medical and mental health conditions, and is gaining recognition and integration in the traditional field of mental health. There is an increasing amount of evidence that supports the effectiveness of equine-assisted therapy in a therapeutic setting.
Studies have resulted in a bibliography that backs up the therapeutic value of human-animal interaction. EAP has been found to be beneficial for those suffering from depression, anxiety, ADHD, behavioral disorders, addictions, trauma, eating disorders, spectrum and health difficulties, dissociative disorders, Alzheimer's disease, dementia, and other mental health issues. The therapist must have specific training in equine-assisted therapy as well as traditional training in the field of mental health. A systematic review of the effectiveness of complementary and adjuvant therapies and interventions with horses has been conducted.
