Though much is known about obsessive-compulsive disorder and depression individually, not much research has been done to look at the comorbidity of the two mental illnesses. This study seeks to review the comorbidity of obsessive-compulsive disorder (OCD) and depression in a college sample. Comorbidity between mental illnesses like OCD and depression is important to study because results will implicate what symptoms should be of concern, and these symptoms should be used to consider treatment. Understanding symptoms of both illnesses, and how they relate, can drive future research on what the best treatment options are for individuals diagnosed with these illnesses. This study measured depression with various subtypes of OCD through an online SONA survey. Data was collected from a sample of l 05 college students. Furthermore, results showed an overall correlation between depression and OCD rates overall. Obsessive subtypes had higher correlations within those with depressive symptoms than did compulsive subtypes. This study indicates that further research needs to be done to understand treatment outcomes of those with comorbid OCD and depression. More studies should take into account for the complexity of OCD subtypes when measuring comorbidity.
