Regarding symptoms, Obsessive-Compulsive Disorder (OCD) is a heterogeneous disorder, and the dimensions of contamination, harm, unwanted thoughts, and symmetry may vary in each patient. This study aims to investigate cognitive and emotional factors that are considered effective on OCD dimensions. One hundred ten patients with OCD and 104 healthy controls were included in this study. Dimensional Obsessions and Compulsions Scale (DOCS), Obsessive Beliefs Questionnaire-44 (OBQ-44), State-Trait Anxiety Inventory (STAI), State-Trait Anger Expression Inventory (STAXI), Guilt Inventory (GI), Disgust Scale (DS-R), Leahy Emotional Schema Scale-II (LESS-II), and Beck Depression Inventory (BDI) were administered to the OCD with healthy control to check clinical differences. As a result of the study, it was found that both cognitive and emotional factors and their relations with each other varied depending on the OCD dimensions. OCD is a disorder that differs in each patient in terms of clinical course, response to treatment, and age of onset. Establishing the cognitive and emotional factors that may be related to the difference might be significant for developing therapeutic interventions focused on these factors.
