许多量表和评估可用于评估性强迫（SC）。本研究试图对性强迫量表（SCS）进行项目反应理论（IRT）分析，以在性行为高度活跃的男同性恋和双性恋男性（GBM）样本中，为其在SC结构的各个层次上的测量精度提供证据。来自202名性活跃但SC症状经历不同的GBM样本的SCS数据使用Samejima的多瘤分级反应IRT模型建模。为了描述SCS相对于HDSI的表现，将SCS评分与参与者相应的HDSI结果进行比较，以确定敏感性、特异性、阳性和阴性预测值以及准确性。本研究考察了SCS与超性欲障碍筛查量表（Hypersexual Disorder Screening Inventory， HDSI）之间的对应关系，超性欲障碍筛查量表是一种用于筛查超性欲的诊断工具。IRT分析表明，尽管SCS中有两个项目的信度较低，但整个SCS在SC连续体的大部分内容中是可靠的。SCS得分与HDSI得分高度相关；然而，没有SCS的潜在截止点与HDSI的综合评分标准强烈对应。SCS评分与HDSI结果的比较表明，SCS本身不能作为HDSI的替代品，并且会错误地分类大量个体的性欲亢进水平。然而，SCS可以作为一种有用的筛查工具，为符合HDSI标准的高危人群提供初步筛查。结合SCS和HDSI可能是一种适当的评估策略，可以将GBM分类为两个阴性（即“非性亢进/非SC”），仅SCS阳性（即“有风险”），以及SCS和HDSI均阳性（即“有问题的性亢进/SC”）。
Numerous scales and assessments are available to assess sexual compulsivity (SC). This study sought to conduct an Item Response Theory (IRT) analysis of the Sexual Compulsivity Scale (SCS) to provide evidence about its measurement precision at the various levels of the SC construct in a sample of highly sexually active gay and bisexual men (GBM). SCS data from a sample of 202 GBM who are highly sexually active but who vary in their experiences of SC symptoms were modeled using Samejima's polytomous graded response IRT model. To describe the performance of the SCS relative to the HDSI, SCS scores were compared with participants’ corresponding HDSI results to determine sensitivity, specificity, positive and negative predictive values, and accuracy. This study examined the correspondence between the SCS and the Hypersexual Disorder Screening Inventory (HDSI), a diagnostic instrument for the screening of hypersexuality. IRT analyses indicated that, although two of the SCS items had low reliability, the SCS as a whole was reliable across much of the SC continuum. Scores on the SCS and the HDSI were highly correlated; however, no potential cutoffs on the SCS corresponded strongly with the polythetic scoring criteria of the HDSI. Comparisons of SCS scores with HDSI results indicated that the SCS itself could not serve as a substitute for the HDSI and would incorrectly classify a substantial number of individuals’ levels of hypersexuality. However, the SCS could be a useful screening tool to provide a preliminary screening of people at risk for meeting criteria on the HDSI. Combining the SCS and the HDSI may be an appropriate evaluation strategy in classifying GBM as negative on both (i.e., “non-hypersexual/non-SC”), positive on the SCS only (i.e., “at risk”), and positive on both the SCS and the HDSI (i.e., “problematic hypersexuality/SC”).
