Differences by sexual orientation in treatment outcome and satisfaction with treatment among inpatients of a German psychiatric clinic.

A wealth of research suggests that sexual minority individuals experience stigma and lack of sexual minority specific competencies in mental health care, which could lead to less optimal treatment outcome. However, most related research suffers from methodological limitations, such as selected samples, retrospective design, or not assessing treatment outcome. To overcome some of these limitations, we explored if sexual minority patients have poorer treatment outcome and are less satisfied with treatment in a mental health care setting not specialized in sexual minority issues. The analytical sample comprised 5609 inpatients, including 11% sexual minority patients, from a German psychiatric clinic. Outcomes were improvement in well-being and depression from admission to discharge, and satisfaction with treatment judged at discharge. Nearly all sexual orientation differences were in a direction hinting at less improvement of depression and well-being and less satisfaction among sexual minority compared to heterosexual patients. However, the differences were generally small and not statistically significant. Stigma and lacking sexual orientation specific competency in healthcare may not be universally present or not as severe as studies with other research designs suggested. However, this needs to be investigated in more clinical settings by including sexual orientation as part of the routine assessment. Moreover, adequate sexual-minority specific competencies are important in any case, not just to prevent that sexual minority patients benefit less from treatment.
