Responses to autobiographical memories involving being a victim or perpetrator of betrayal in people with OCD and community controls.

Mental contamination in people with OCD has been linked to the perceived impact of being betrayed and betraying others. In this study, participants with OCD (N = 56) and community controls (N = 37) were randomised to an induction involving eliciting autobiographical memories of either being betrayed by someone they trusted or betraying someone that trusted them. The OCD group experienced greater increases in state mental contamination and anxiety than the control group, but no differences were observed between groups in urges to wash or drink.
