Obsessive-compulsive disorder (OCD) is a mental disorder characterised by obsessions and compulsions. In OCD, obsessions are manifested by recurrence and persistence of unwanted thoughts, whereas the compulsions can be manifested as a variety of behaviours in response to this obsession (DSM-V), (Bokor and Anderson, 2014). It has no restriction of cultural or ethnic group (Lewis-Fernández, Hinton, Laria, Patterson, Hofmann, Craske,... Liao, 2010). The prevalence among females is slightly higher than in males (Ruscio, Stein, Chiu and Kessler, 2010), and it is common for individuals presenting OCD to be also affected by other mental disorders, particularly major depression and other anxiety-related disorders (Ruscio et al,2010).
