Sexual addiction is a pathological behavior characterized by a combination of excessive sexual desire and impaired ability to control it. Its incidence ranges between 1.2% and 32.2%, although this number may vary depending on the screening tool used. This wide variability is largely due to the use of non-validated instruments (e.g., structural validity relying on exploratory analyses, instruments translated without an additional validation process, or instruments validated in another format). To deal with these limitations, this study tested the psychometric properties of the Spanish paper-and-pencil and online versions of the Sexual Addiction Screening Test (SAST).
A total of 2,528 participants (1,163 males) completed the Spanish version of the SAST, along with other instruments assessing sexual compulsivity (1,585 = paper-and-pencil, 943 = online).
The exploratory factor analysis yielded a four-factor structure explaining 57.39% of the variance for the SAST paper-and-pencil version. This factor structure was then verified for the online version through the use of confirmatory factor analysis [χ(264) = 441.59; χ/df = 1.66; RMSEA = 0.02; CFI = 0.94; IFI = 0.94]. This methodology was also used to support measurement invariance (configural, metric, and scalar invariance) according to gender. The reliability of the total score ranged from .82 to .85. Similarly, correlations with related scales were positive and significant (r between .22 and .71). Temporal stability 1 year after the first application was 0.65 (paper-and-pencil format) and 0.60 (online version).
These results, together with the absence of questionnaires translated into Spanish to assess this construct, justify the use of the SAST in the evaluation of sexual addiction in Spanish-speaking countries.
性成瘾是一种病理性行为，其特征是性欲过度和控制能力受损。其发病率在 1.2%至 32.2%之间，尽管这一数字可能因所使用的筛查工具而异。这种广泛的变异性在很大程度上是由于使用了未经验证的工具（例如，结构有效性依赖于探索性分析、未经额外验证过程翻译的工具或在另一种格式中验证的工具）。为了解决这些限制，本研究测试了性成瘾筛查测试（SAST）的西班牙纸笔版和在线版的心理测量特性。
共有 2528 名参与者（1163 名男性）完成了 SAST 的西班牙语版本，以及其他评估性强迫性的工具（1585 名=纸笔版，943 名=在线版）。
探索性因素分析得出了一个四因素结构，解释了 SAST 纸笔版的 57.39%的方差。然后通过验证性因素分析（χ(264)=441.59；χ/df=1.66；RMSEA=0.02；CFI=0.94；IFI=0.94）验证了在线版的这种结构。该方法还用于根据性别支持测量不变性（结构、度量和标度不变性）。总分的信度范围在 0.82 到 0.85 之间。同样，与相关量表的相关性为正且显著（r 在 0.22 到 0.71 之间）。第一次应用一年后的时间稳定性为 0.65（纸笔版）和 0.60（在线版）。
这些结果，以及没有西班牙语问卷来评估这一结构，证明了 SAST 在西班牙语国家评估性成瘾的使用是合理的。
