Quizplus · Accepted Answer

To diagnose obsessive-compulsive disorder (OCD) using DSM-5, the clinician must compare Michael's symptoms to a specific set of diagnostic criteria outlined in the manual. The DSM-5 criteria for OCD include the presence of obsessions (persistent, intrusive, and unwanted thoughts) and/or compulsions (repetitive behaviors or mental acts that aim to reduce anxiety caused by obsessions) that cause significant distress, take up a lot of time, and interfere with daily functioning. No extensive psychological testing or brain scans are required to arrive at an OCD diagnosis. However, the clinician may refer Michael to a physician to rule out any underlying medical conditions that could mimic OCD symptoms, such as hyperthyroidism or drug-induced OCD.
