Obsessive-Compulsive Disorder

The 'Diagnostic and Statistical Manual of mental Disorders - fifth edition' (DSM-5; APA, 2013) identifies obsessive-compulsive disorder (OCD) as being characterized by obsessions and/or compulsions. Obsessions are defined as: 1. Recurrent and persistent thoughts, urges, or impulses that are experienced, at some time during the disturbance, as intrusive and unwanted, and that in most individuals cause marked anxiety or distress. 2. The individual attempts to ignore or suppress such thoughts, urges or images, or to neutralize them with some other thought or action (i.e., by performing a compulsion). Compulsions are defined as: 1. Repetitive behaviors or mental acts that the individual feels driven to perform in response to an obsession or according to rules that must be applied rigidly. 2. The behaviors or mental acts are aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation; however, these behaviors or mental acts are not connected in a realistic way with what they are designed to neutralize or prevent, or are clearly excessive.
