Sexual minority individuals experience higher rates of psychopathology, such that sexual minority people are nine times more likely to receive a diagnosis or treatment for obsessive-compulsive disorder (OCD) compared to heterosexual people. Poor emotion regulation capacity is a risk factor for OCD, but little is known about sexual orientation differences in dimensions of emotion regulation and how dimensions of emotion regulation relate to OCD severity among sexual minority people. The aims of the current study include 1) comparing sexual minority to heterosexual people on OCD severity and emotion regulation capacity upon admission to treatment for OCD, and 2) examining emotion regulation in relation to OCD severity among sexual minority people. Participants (N = 470) were adults in partial hospital/residential treatment with an average stay of 59.7 days (SD = 25.3), including 22 % sexual minority people. Sexual minority people reported a lower emotion regulation capacity. Among the largest three subgroups (heterosexual, bi+, and gay/lesbian), bi+ individuals reported a lower emotion regulation capacity compared to heterosexual but not gay/lesbian people. Results suggest there are sexual orientation differences in emotion regulation capacity, and that bi+ people have the most difficulty with ER. There is a need for OCD treatment to directly target emotion regulation strategies and be affirming of sexual minority identities.

性少数群体的精神病理学发病率更高，因此性少数群体接受强迫症 (OCD) 诊断或治疗的可能性是异性恋者的九倍。情绪调节能力差是强迫症的危险因素，但人们对情绪调节维度上的性取向差异以及性少数人群情绪调节维度与强迫症严重程度之间的关系知之甚少。当前研究的目的包括：1）比较性少数群体与异性恋群体的强迫症严重程度以及接受强迫症治疗时的情绪调节能力；2）检查性少数群体中与强迫症严重程度相关的情绪调节能力。参与者 (N = 470) 是接受部分医院/住院治疗的成年人，平均住院时间为 59.7 天 (SD = 25.3)，其中包括 22% 的性少数群体。性少数群体的情绪调节能力较低。在最大的三个亚群体（异性恋、双性恋和男同性恋）中，双性恋者的情绪调节能力低于异性恋者，但男同性恋者则不然。结果表明，情绪调节能力存在性别取向差异，双性恋+人的ER最困难。强迫症治疗需要直接​​针对情绪调节策略并肯定性少数群体的身份。
