BackgroundSexual response in obsessive–compulsive disorder (OCD) research and practice is overlooked. According to the Dual Control Model, satisfactory sexual response is based upon a balance of sexual excitation and inhibition. The assessment of sexual response in OCD may have clinical implications, such as the integration of sex therapy in psychotherapeutic intervention. The present study was aimed at comparing sexual excitation and inhibition levels between OCD patients and matched control subjects, and investigating whether obsessive beliefs might predict sexual excitation/inhibition.MethodsSeventy-two OCD patients (mean age ± standard deviation [SD]: 34.50 ± 10.39 years) and 72 matched control subjects (mean age ± SD: 34.25 ± 10.18) were included (62.50% men and 37.50% women in both groups). The Obsessive Compulsive Inventory-Revised (OCI-R), the Obsessive Beliefs Questionnaire-46 (OBQ-46), and the Sexual Inhibition/Sexual Excitation Scales (SIS/SES) were administered.ResultsPatients with OCD showed significantly higher levels of sexual excitation, inhibition due to threat of performance failure, and inhibition due to threat of performance consequences than the controls. In addition, the patients with more severe symptoms showed lower excitation than those with less severe symptoms, and those with higher perfectionism had stronger inhibition due to threat of performance failure than those with lower perfectionism.ConclusionsThis is the first study exploring sexual response in OCD according to the Dual Control Model. Sexual response is an impaired quality of life outcome in OCD that should be assessed in routine clinical practice. These findings support the importance of addressing specific obsessive beliefs to improve sexuality in OCD patients.

强迫症的性反应：强迫信念的作用

背景强迫症 (OCD) 研究和实践中的性反应被忽视。根据双重控制模型，令人满意的性反应是基于性兴奋和抑制的平衡。对强迫症性反应的评估可能具有临床意义，例如将性治疗整合到心理治疗干预中。本研究旨在比较强迫症患者和匹配的对照受试者之间的性兴奋和抑制水平，并调查强迫信念是否可以预测性兴奋/抑制。方法七十二名强迫症患者（平均年龄±标准差[SD]：34.50±10.39年）和 72 名匹配的对照受试者（平均年龄 ± SD：34.25 ± 10.18）被纳入（两组中男性占 62.50%，女性占 37.50%）。强迫性库存修订版（OCI-R），使用强迫信念问卷 46 (OBQ-46) 和性抑制/性兴奋量表 (SIS/SES)。对绩效后果的威胁比控制。此外，症状较重的患者比症状较轻的患者表现出较低的兴奋，而完美主义较高的患者因表现失败的威胁而比完美主义较低的患者具有更强的抑制作用。到双重控制模型。性反应是强迫症患者生活质量受损的结果，应在常规临床实践中进行评估。
