According to the DSM-IV-TR (2000), kleptomania is the “recurrent failure to resist the impulses to steal objects that are not needed for personal use or for their monetary value.”
Prior to the stealing, there is an increase of tension, and after the theft, that tension is relieved. Further, “the stealing is not committed to express anger or vengeance,” nor is it better accounted for by another disorder, such as antisocial personality disorder, or in response to a hallucination.
Although OCD involves compulsive behaviors that neutralize obsessive impulses, if those impulses and behaviors are strictly limited to stealing, then Kleptomania better accounts for the problem than OCD. If there are impulses beyond stealing, then it’s likely OCD.
Research also indicates that the relatives of individuals with kleptomania have higher rates of OCD than are found in the general population.
