Investigation of Obsessive-Compulsive Disorder in Patients With Elbow Epicondylitis

This study will compare obsessive-compulsive symptoms in adults with medial and/or lateral elbow epicondylitis (pain and tenderness on the inner and/or outer side of the elbow). The study will include 90 participants in two groups of 45. One group will have no identifiable history of mechanical loading associated with their elbow condition. The other group will have a history of activities that place repeated strain on the elbow, such as manual work, sports, or caregiving. Group assignment will be based on medical history and clinical assessment, rather than random allocation. Each participant will complete the Turkish self-report Yale-Brown Obsessive Compulsive Scale and the 37-item Turkish Maudsley Obsessional Compulsive Inventory once, at the study visit. The main outcome will be the Yale-Brown total score. The Maudsley total score will be a secondary outcome. The study will assess symptoms, not establish a diagnosis of obsessive-compulsive disorder. No treatment will be assigned as part of the study, and no follow-up visits are planned.
