Exposure and Response Prevention (EX/RP) involves two components: 1) provoking obsessions and maintaining the subsequent anxiety, and 2) refraining from engaging in rituals. The purpose of this process is to allow the patient to habituate to the obsession-related anxiety; thus, the contingency between the obsessions and compulsions is weakened, and the patient learns that anxiety resulting from the obsession will habituate on its own. Exposures are conducted hierarchically, with less feared stimuli presented first. Exposure may be conducted imaginally or in vivo. Imaginal exposure often focuses on the feared consequences of obsessions. For example, a woman who performs counting rituals to neutralize obsessions about accidentally killing her husband may be asked to vividly imagine killing her husband, while refraining from counting. In vivo exposure involves bringing the patient into the actual presence of feared stimuli. For example, a patient with contamination fears may be asked to sit on the bathroom floor for a specified amount of time, without washing his/her hands or taking a shower. EX/RP is often conducted in conjunction with cognitive therapy techniques. EX/RP typically lasts 12 to 16 sessions; although it is probably often provided on a once-weekly basis, it can be delivered more frequently (e.g., daily or twice-weekly).
