Obsessive-compulsive disorder (OCD) is characterized by persistent, distressing obsessive thoughts or repetitive compulsive behaviors. Common behaviors include excessive hand washing (related to contamination fears), repeated checking (such as door locks), mental counting, or arranging objects, all aimed at reducing anxiety. Option C corresponds to post-traumatic stress disorder; Option E is more closely associated with social anxiety disorder.
美國臨床更依賴 DSM-5 診斷標準進行精確評估；台灣臨床常將此類行為視為過度焦慮的表現。
