The Sexual Excitation Sexual/Inhibition Inventory for Women and Men (SESII-W/M) and the Sexual Excitation Scales/Sexual Inhibition Scales short form (SIS/SES-SF) are two self-report questionnaires for assessing sexual excitation (SE) and sexual inhibition (SI). According to the dual control model of sexual response, SE and SI differ between individuals and influence the occurrence of sexual arousal in given situations. Extreme levels of SE and SI are postulated to be associated with sexual difficulties or risky sexual behaviors. The present study was designed to assess the psychometric properties of the German versions of both questionnaires utilizing a large population-based sample of 2,708 participants (Mage = 51.19, SD = 14.03). Overall, psychometric evaluation of the two instruments yielded good convergent and discriminant validity and mediocre to good internal consistency. The original 30-item version of the SESII-W/M did not show a sufficient model fit. For a 24-item version of the SESII-W/M partial strong measurement invariance across gender, and strong measurement invariance across relationship status, age, and educational levels were established. The original structure (14 items, 3 factors) of the SIS/SES-SF was not replicated. However, a 4-factor model including 13 items showed a good model fit and strong measurement invariance across the before-mentioned participant groups. For both questionnaires, partial strong measurement invariance with the original American versions of the scales was found. As some factors showed unsatisfactory internal consistency and the factor structure of the original scales could not be replicated, scores on several SE- and SI-factors should be interpreted with caution. However, most analyses indicated sufficient psychometric quality of the German SESII-W/M and SIS/SES-SF and their use can be recommended in German-speaking samples. More research with diverse samples (i.e., different sexual orientations, individuals with sexual difficulties) is needed to ensure the replicability of the factor solutions presented in this study.
《女性和男性性唤起/性抑制量表》（SESII-W/M）和《性唤起量表/性抑制量表简式》（SIS/SES-SF）是两种自评问卷，用于评估性唤起（SE）和性抑制（SI）。根据性反应的双重控制模型，SE 和 SI 在个体之间存在差异，并影响特定情境下性唤起的发生。极端的 SE 和 SI 水平被假定与性困难或危险的性行为有关。本研究旨在利用一个由 2708 名参与者（Mage = 51.19，SD = 14.03）组成的大型基于人群的样本，评估这两种问卷的德文版本的心理测量特性。总体而言，这两种工具的心理测量评估得出了良好的收敛和区分效度，以及中等至良好的内部一致性。SESII-W/M 的原始 30 项版本没有表现出足够的模型拟合。对于 SESII-W/M 的 24 项版本，在性别、关系状况、年龄和教育水平上建立了部分强测量不变性。SIS/SES-SF 的原始结构（14 项，3 个因素）没有得到复制。然而，包括 13 项的 4 因素模型表现出良好的模型拟合和在上述参与者群体中具有强测量不变性。对于这两种问卷，都发现了与原始美国版本量表的部分强测量不变性。由于一些因素的内部一致性不尽如人意，并且原始量表的结构无法复制，因此应谨慎解释几个 SE 和 SI 因素的分数。然而，大多数分析表明，德文 SESII-W/M 和 SIS/SES-SF 的心理测量质量足够，可以在德语样本中使用。需要更多具有不同样本（即不同性取向、有性困难的个体）的研究来确保本研究中提出的因子解决方案的可重复性。
