Obsessive-Compulsive Disorder (OCD):


A condition that is characterized by the presence of obsessions and/or compulsions. Obsessions are recurrent, intrusive thoughts usually irrational worries that often necessitate behaviors to prevent untoward consequences (e.g., fears of contamination from dirt requiring the individual to wear gloves at all times). Compulsions are recurrent behaviors that the individual feels compelled to undertake which are beyond what are considered normal, usually to preserve personal safety, to avoid embarrassment, to perform adequately (e.g., checking multiple times to see that the gas is turned off before leaving home).
