Sexual desire is a complex construct with important implications for sexual functioning and well-being. In this research, we translated the Sexual Desire Inventory (SDI-2), a widely used scale for assessing sexual (desire), into 25 languages from English and used data from the International Sex Survey (ISS) to (a) investigate its psychometric properties (i.e. factorial structure, reliability, validity, and measurement invariance) and (b) explore the expression of sexual desire across different countries, genders, and sexual orientations. A total of 82,243 participants from 42 countries completed the SDI-2, along with other sexuality-related scales. Confirmatory factor analysis supported a three-factor solution for the SDI-2 (CFI = .980; RMSEA = .060), encompassing the domains of "Partner-related," "Attractive-person-related," and "Solitary" sexual desire. The reliability of the total score and subscales were excellent. Likewise, correlations with other sexuality-related variables were positive yet weak-to-moderate in effect size. Measurement invariance tests supported its use across countries, languages, genders, and sexual orientations. Analysis of SDI-2 scores according to these variables supported its ability to capture group-based differences in sexual desire. In sum, the SDI-2 constitutes a psychometrically robust measure for the assessment of sexual desire in non-clinical samples with utility in large-scale cross-cultural studies.

在 42 个国家和 26 种语言中对量表 （SDI-2） 进行跨文化验证。


是一个复杂的结构，对性功能和性健康具有重要影响。在这项研究中，我们将量表 （SDI-2），一种广泛用于评估性（欲望）的量表，从英语翻译成 25 种语言，并使用国际性调查 （ISS） 的数据来 （a） 调查其心理测量特性（即 因子结构、可靠性、有效性和测量不变性）和 （b） 探索不同国家的表达， 性别和性取向。共有来自 82,243 个国家/地区的 42 名参与者完成了 SDI-2 以及其他与性相关的量表。验证性因子分析支持 SDI-2 的三因素解决方案 （CFI = .980;RMSEA = .060），包括 “伴侣相关”、“有吸引力的人相关 ”和 “孤独 ”领域。总分和分量表的可靠性非常好。同样，与其他性相关变量的相关性为正，但效应大小为弱到中等。测量不变性检验支持其在不同国家、语言、性别和性取向中的使用。根据这些变量对 SDI-2 评分的分析支持其捕捉基于群体的差异的能力。总之，SDI-2 构成了一种心理测量学稳健的测量方法，用于评估非临床样本中的，在大规模跨文化研究中具有实用性。
