Compulsive behavior (or compulsion) is defined as performing an action persistently and repetitively. Compulsive behaviors could be an attempt to make obsessions go away.[3] Compulsive behaviors are a need to reduce apprehension caused by internal feelings a person wants to abstain from or control.[4] A major cause of compulsive behavior is said to be obsessive–compulsive disorder (OCD).[3][5] "Compulsive behavior is when someone keeps doing the same action because they feel like they have to, even though they know these actions do not align with their goals."[6] There are many different types of compulsive behaviors including shopping, hoarding, eating, gambling, trichotillomania and picking skin, itching, checking, counting, washing, sex, and more. Also, there are cultural examples of compulsive behavior.
