We have seen the joy pets bring into people’s lives, and the sadness that follows the loss of them. Many pet owners view their pets as more than just animals: they are family. They offer a level of love and support similar to friends and family, despite not being human. Some pets are also trained as service animals to assist humans who struggle with diagnosed physical, mental, and other disabilities. However, emotional support animals appear to lie somewhere between pets and service animals, as there are rules and policies still developing around them. With more and more college students requesting to bring ESAs on campus, the question of their effectiveness has been raised. The aim of this honors thesis study is to examine the effectiveness of ESAs in alleviating mental health symptoms in college students. More specifically, I wanted to evaluate students who currently live on campus (or have lived on campus in the past). The first aim will be to determine whether non-pet owners versus ESA owners (and pet owners in general) show a difference in their stress levels. The second aim is to examine if owning a pet or ESA predicts stress levels differently between genders. The final aim of the study is to determine if degree of attachment to pets predicts differences in stress in the owners.
