Examination of outcomes among sexual minorities in treatment for obsessive-compulsive and related disorders

Abstract

The first-line psychological treatment for obsessive-compulsive and related disorders (OCRDs) is exposure and response prevention (ERP). As the first study to examine treatment outcomes for sexual minorities, it is crucial to examine: (1) how treatment-seeking individuals who identify as sexual minorities compare to heterosexual individuals in symptom severity at admission, length of stay in treatment, and (2) whether ERP is equally effective for sexual minorities. The current study explored these questions in an intensive/residential treatment (IRT) program for OCRDs. Adult participants (N = 191) completed self-reported measures of OCD severity, distress tolerance, and depression at program admission, in the first four weeks of treatment, and at discharge. No differences were found between groups for treatment outcome, although slight differences (non-significant) emerged at baseline for OCRD severity, distress tolerance, and depression. Sexual orientation was not predictive of OCRD severity at weeks 1–4, and number of days spent in treatment was not associated with sexual orientation. This is the first study exploring whether sexual orientation is predictive of treatment outcomes for individuals diagnosed with OCRDs. Results suggest that outcomes did not differ and participation in the program resulted in an overall improvement of symptoms regardless of sexual orientation, however several study limitations are discussed. Future studies should replicate these findings, attempt to collect a larger sample, incorporate qualitative feedback from treatment, and examine outcomes in gender minorities.
