INTRODUCTION
The Hypersexual Disorder Screening Inventory (HDSI) was designed as an instrument for the screening of hypersexuality by the American Psychiatric Association's taskforce for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders.
AIM
Our study sought to conduct a psychometric analysis of the HDSI, including an investigation of its underlying structure and reliability utilizing item response theory (IRT) modeling, and an examination of its polythetic scoring criteria in comparison to a standard dimensionally based cutoff score.
METHODS
We examined a diverse group of 202 highly sexually active gay and bisexual men in New York City. We conducted psychometric analyses of the HDSI, including both confirmatory factor analysis of its structure and IRT analysis of the item and scale reliabilities.
MAIN OUTCOME MEASURES
We utilized the HDSI.
RESULTS
The HDSI adequately fit a single-factor solution, although there was evidence that two of the items may measure a second factor that taps into sex as a form of coping. The scale showed evidence of strong reliability across much of the continuum of hypersexuality, and results suggested that, in addition to the proposed polythetic scoring criteria, a cutoff score of 20 on the severity index might be used for preliminary classification of HD.
CONCLUSION
The HDSI was found to be highly reliable, and results suggested that a unidimensional, quantitative conception of hypersexuality with a clinically relevant cutoff score may be more appropriate than a qualitative syndrome comprised of multiple distinct clusters of problems. However, we also found preliminary evidence that three clusters of symptoms may constitute an HD syndrome as opposed to the two clusters initially proposed. Future research is needed to determine which of these issues are characteristic of the hypersexuality and HD constructs themselves and which are more likely to be methodological artifacts of the HDSI.
简介
《性欲过度障碍筛查量表》（HDSI）是由美国精神病学协会工作组为《精神障碍诊断与统计手册》第五版设计的，用于筛查性欲过度。
目的
我们的研究旨在对 HDSI 进行心理测量学分析，包括使用项目反应理论（IRT）模型对其潜在结构和可靠性进行调查，并与标准维度基于截止分数的多标准评分标准进行比较。
方法
我们检查了来自纽约市的 202 名高度活跃的男同性恋和双性恋男性的多样化群体。我们对 HDSI 进行了心理测量学分析，包括对其结构的验证性因素分析和项目和量表可靠性的 IRT 分析。
主要结果测量
我们使用了 HDSI。
结果
HDSI 足够适合单因素解决方案，尽管有证据表明两个项目可能测量第二个因素，即性行为作为应对方式。该量表在整个性欲过度的连续体上都表现出了很强的可靠性，结果表明，除了拟议的多标准评分标准外，严重指数上的 20 分的截止分数可能用于初步分类 HD。
结论
发现 HDSI 高度可靠，结果表明，具有临床相关截止分数的单一维度、定量的性欲过度概念可能比由多个不同问题集群组成的定性综合征更合适。然而，我们也发现了初步证据，表明三个症状集群可能构成 HD 综合征，而不是最初提出的两个集群。需要进一步的研究来确定这些问题中哪些是性欲过度和 HD 结构本身的特征，哪些更可能是 HDSI 的方法学artifact。
