Depending on their preference in etiological models, psychologists treat bulimia nervosa differently. For psychologists following the biological model of abnormality, one popular method to treat bulimia nervosa is to prescribe antidepressant medication. Through extensive research on the subject, psychologists know that certain psychotropic medications effectively treat bulimia nervosa. Despite these positive results, psychologists do consider other treatment methods. Recent research results suggest that a comprehensive treatment which includes both antidepressants and cognitive-behavioral therapy…show more content…

Binging is when an individual repeatedly overeats, usually without any conscious control (Comer, 2014). For psychologists working under the biological model, various factors within in an individual’s biology causes bulimia nervosa. Potential biological factors include abnormalities in a person’s genetics, neuroendocrine levels, and internal awareness (Polivy & Herman, 2002). For example, some psychologists propose that a lack of 5-HT at least partially causes individuals to develop bulimia nervosa (Polivy & Herman,…show more content…
First, a group of researchers conducts a literature review and found that their data suggests that treatment by psychotropic medication possess a greater possibility of negative side effects than other treatment options (Shapiro et al., 2007). The same researchers state that the current literature weakly supports the idea that a combination of psychotropic medication and cognitive-behavioral therapy is superior to treatment by medication alone, but that more research in this area should be done (Shapiro et al., 2007). Comer argues that treatment by medication is the most effective when combined with some other treatment
