Obsessive compulsive disorder (OCD) is a disabling condition associated with significant personal and societal burdens. Despite the availability of efficacious treatments, in most cases, the disorder remains unrecognized and untreated. Lack of knowledge (i.e. poor mental health literacy, MHL) regarding OCD may be an impediment to seeking treatment. Therefore, the current study assessed public knowledge and beliefs about OCD and examined factors influencing MHL.
