Background Patients from ethnic minority backgrounds are underrepresented in clinical settings. Factors like cost of treatment, poor knowledge of the health system, geographic availability of services, lack of mental health literacy, differences in health beliefs, and social barriers have been identified as reasons for these inequalities. The aim of this study was to identify and compare barriers that parents from different ethnic groups face when accessing specialist services for obsessive–compulsive disorder (OCD) for their children. Method Ten parents from White backgrounds and 10 from ethnic minority backgrounds were recruited from the National and Specialist OCD, BDD, and Related Disorders Clinic for Young People, London, United Kingdom. They were interviewed about their opinions and experiences when accessing treatment. Results Using thematic analysis, several common barriers for both groups were identified. These included a lack of knowledge of OCD, lack of resources within the health system, previous negative experiences, lack of trust in the mental health system, lack of time and financial issues, no support out of hours, bullying, and inconvenient location of services. In addition, there were several barriers that were endorsed by ethnic minority groups but not by the parents from White backgrounds, namely stigma and discrimination from within their communities, shame and denial, a general lack of trust in the health system by their cultural group, different beliefs about mental health issues, and discrimination from within the system. Conclusions Policy‐makers and clinicians should be aware of the additional barriers minority patients may face in accessing treatment and should support interventions designed to overcome them.
