Historically, people with psychiatric disorders or overt psychopathological manifestations have been a constant target of stigma, defined as an adverse social judgment about a person or group. One possible manifestation of stigma is internalized stigma (IS) or self-stigma, i.e., the stigma people experience about their own condition. The relationship between obsessive-compulsive disorder (OCD) and IS remains poorly understood. This exploratory study aimed to evaluate potential associations between stigma, IS, and OCD.
