The Efficacy of Animal-assisted Therapy in Reducing Addictive Behaviors in Psychiatric Patients
Many studies exist on the efficacy of animal-based therapy in reducing maladaptive coping mechanisms in patients suffering from compulsive and addictive behaviors as are commonly found in alcoholism, eating disorders, and obsessive compulsive disorder. In fact, animal-assisted therapy (AAT) has been used by a small sub-set of treatment centers and therapists since the 1970’s, especially equine-assisted therapy, although many treatment professionals are implementing companion animals such as dogs and cats; “pocket pets” like like rats and guinea pigs; and even more unusual animals like dolphins [1,3,4].
The health benefits of companion animals have been indicated in a variety of studies, including significant decreases in blood pressure, depression, and anxiety, as well as improvements in confidence and communication [2,3,5]. For example, one researcher found a significant increase in serum levels of neurotransmitters associated with lowered blood pressure, as well as an increase in endorphins, which cause elevated mood; oxytocin, commonly referred to as the “bonding chemical”; and even dopamine, low levels of which have long been correlated with several mental illnesses [5,6].
Additionally, the implementation of animals in a treatment environment has been correlated with a decrease in negative behaviors and an increase in positive behaviors by many studies, as well [5,7]. For example, two separate studies found an increase in communication between patient and treatment provider in situations in which a therapy animal present, as well as an increase in body image and self-confidence [7,8]. Further studies have indicated an increase in body confidence in equine-assisted therapy in which a patient becomes more attuned to the movements of his or her body while riding horseback .
Therefore, many treatment professionals think the introduction and utilization of trained animals within a treatment environment would be prudent and beneficial to patients struggling with destructive coping mechanisms considering the positive effects on many patients in the presence of a trained therapy animal. While animal-assisted therapy cannot treat psychiatric illnesses alone, the benefits of having a trained therapy animal within a treatment environment can often enhance the effects of the treatment itself. In summary, the addition of a trained therapy animal to the treatment plan of a psychiatric patient can result in positive physiologic effects such a decrease in blood pressure and stress hormones as a result of decreased levels of depression and anxiety, as well as an increase in communication and self-confidence, all of which are important factors in psychiatric treatment for a variety of mental illnesses.
