How resistant is 'treatment-resistant' obsessive-compulsive disorder in youth?

Objectives: Obsessive-compulsive disorder (OCD) is often perceived as being difficult to treat. This study aimed to test the hypothesis that treatment non-response in routine clinical practice is often due to failures in the delivery of treatment, and that most patients who are apparently treatment-resistant will respond to treatment if adequately delivered.

Design: Retrospective cohort data analysis.
