Sexual satisfaction is a crucial part of sexual health and is positively related to well-being and quality of life. However, there are at present no composite measures of sexual satisfaction available in Swedish. The New Sexual Satisfaction Scale - Short form (NSSS-S) is a measure of sexual satisfaction that has been validated in multiple languages, and the aim of the present study is to evaluate the psychometric properties and intelligibility of a Swedish version of the NSSS-S.
A convenience sample (N = 479) responded to an online survey including the Swedish NSSS-S and a single-item measure of sexual satisfaction. Qualitative evaluation of the translation was done within 20 semi-structured interviews where respondents gave open answers to the NSSS-S items.
Results showed that a two-factor solution, matching the subscales Ego-Centred and Partner/Activity-Centred sexual satisfaction, showed good to acceptable fit to the data. However, removal of the item "Partner's ability to orgasm" increased model fit significantly. Internal reliability for the full scale was high and NSSS-S scores correlated strongly with the single-item measure of sexual satisfaction. Qualitative evaluation showed no issues with comprehension of the translated items or with the semantic and cultural validity of the translated measure, but revealed additional aspects of measuring sexual satisfaction not captured by a scale such as the NSSS-S.
The Swedish NSSS-S displayed the expected bi-dimensional factor structure, high convergent validity in relation to the other available measure of sexual satisfaction and can be used with both partnered and single respondents. Qualitative evaluation indicated that the NSSS-S is generally seen to capture important elements of measuring sexual satisfaction but that it may not adequately capture experiences of situational and temporal variability in sexual satisfaction. The Swedish NSSS-S thus showed comparable psychometric and semantic properties to the original version and can be used to measure sexual satisfaction in a Swedish speaking population.
性满意度是性健康的关键组成部分，与幸福感和生活质量呈正相关。然而，目前瑞典语中尚无综合性的性满意度测量工具。新版性满意度量表简版（NSSS-S）是一种已在多种语言中得到验证的性满意度测量工具，本研究旨在评估瑞典语版NSSS-S的心理测量特性和易懂性。
一个便利样本（N = 479）参与了一项在线调查，其中包括瑞典语版NSSS-S和一项性满意度单项测量。在20次半结构化访谈中对翻译进行了定性评估，受访者对NSSS-S项目给出了开放式回答。
结果显示，一个与以自我为中心和以伴侣/活动为中心的性满意度子量表相匹配的双因素模型对数据显示出良好到可接受的拟合度。然而，删除“伴侣达到性高潮的能力”这一项目后，模型拟合度显著提高。全量表的内部信度较高，NSSS-S得分与性满意度单项测量显著相关。定性评估显示，翻译后的项目理解、翻译测量工具的语义和文化效度均无问题，但揭示了诸如NSSS-S这样的量表未涵盖的性满意度测量的其他方面。
瑞典语版NSSS-S呈现出预期的二维因素结构，与其他可用的性满意度测量工具相比具有较高的收敛效度，可用于有伴侣和单身的受访者。定性评估表明，NSSS-S通常被认为能够捕捉性满意度测量的重要元素，但可能无法充分捕捉性满意度在情境和时间上的变化体验。因此，瑞典语版NSSS-S在心理测量和语义特性方面与原版相当，可用于测量瑞典语人群的性满意度。
