What is the difference between Obsessions and Compulsions?

This video describes the differences Obsessions and Compulsions in the context of Obsessive Compulsive Disorder (OCD). Obsessive Compulsive Disorder is characterized by obsessions, compulsions, anxiety, and depression. Obsessions are intrusive thoughts that potentially lead to compulsions. They typically belong to categories such as fear of losing control, fear of contamination, need for approval, fear hurting oneself, fear of hurting another, or fixation on a certain number. Compulsions are behaviors that reduce anxiety. Sometimes compulsions are thoughts, such as planning an event carefully in one’s mind. Examples of compulsions include checking and counting rituals, seeking approval, and ordering objects.
