Obsessive-Compulsive Disorder (OCD) may present with obsessions, compulsions, or both. Obsessions and compulsions are often distressing, time-consuming, and impairing. Everyone has worried about germs or losing something or someone getting hurt. These thoughts tend to be fleeting and do not disrupt daily living. If these thoughts are constantly occurring, uncontrollable, intrusive, and cause a lot of anxiety or stress, then they may be considered 'obsessions.' Everyone has felt the need to double check that the door is locked or arrange items in a correct way. If you perform these actions like a ritual or with rigid rules in order to prevent or reduce anxious thoughts, or if these actions greatly disrupt your life, then they may be considered 'compulsions.' This app is designed to evaluate your symptoms of OCD with a scientifically-supported 18-question test. It uses the Obsessive-Compulsive Inventory - Revised (OCI-R), a screening questionnaire for OCD that is commonly used in research and healthcare settings. The OCI-R is also helpful for monitoring your OCD-related symptoms during and after treatment. OCD Test contains four tools: - Start Test: take the OCI-R questionnaire to assess OCD symptoms - History: see a history of your test scores to monitor your symptoms over time - Information: learn about OCD and discover additional resources that can help you on your path to recovery - Reminder: set up notifications to re-take the questionnaire at your convenience Disclaimer: The OCI-R is NOT a diagnostic test. A diagnosis can only be provided by a qualified healthcare professional. Please consult a physician or mental health professional if you are concerned about OCD.  References: Foa, E. B., Huppert, J.
