A valid and reliable self-administered scale to measure multidimensional aspects of female sexual function is needed in Japan, as sexual dysfunction is quite common in Japanese women.
The aim of this paper is to develop a Japanese translation of the Female Sexual Function Index (FSFI-J), 3-month version, and to measure its psychometric reliability and validity.
Following a language validation process and pilot tests, we modified the scale by adding some instructions and answer options. A cross-sectional survey to examine psychometric reliability and validity of FSFI-J was conducted with 126 healthy Japanese women in partnered relationships. Reliability studies on test-retest and on internal consistency were conducted using the intraclass correlation coefficient (ICC) and Cronbach's α coefficient, respectively. A validity study was conducted on aspects of face, construct, concurrent, and discriminant validity.
The main outcome is the psychometric reliability and validity of FSFI-J.
FSFI-J showed high test-retest reliability (ICC > 0.78) and high internal consistency (Cronbach's α > 0.84). In terms of face validity, FSFI-J was found to be understandable and can adequately measure various aspects of female sexual function. Regarding construct validity, exploratory factor analysis of FSFI-J supported a five-factor solution, consisting of desire/arousal, lubrication, orgasm, satisfaction, and pain. This domain structure was identical to that of the original FSFI. Regarding concurrent validity, FSFI-J total score and domain scores showed significant correlations (Pearson's r = -0.613 for total score) with the sexual function domain of the perimenopausal subjective symptom inventory and overall sexual satisfaction as measured by a visual analog scale (Pearson's r = 0.387). For discriminant validity, the regular menstruation group showed significantly higher FSFI-J scores than the menopause group in the total score and all subdomain scores except sexual satisfaction.
The FSFI-J is a valid and reliable instrument to measure multidimensional aspects of sexual function in healthy Japanese women who are in partnered relationships.
在日本，需要一种有效的、可靠的、可自行管理的量表来测量女性性功能的多维方面，因为性功能障碍在日本女性中相当普遍。
本文旨在开发女性性功能指数（FSFI-J）的日语翻译版本，即 3 个月版本，并测量其心理测量可靠性和有效性。
在语言验证过程和试点测试之后，我们通过添加一些说明和答案选项对该量表进行了修改。对 126 名处于伴侣关系中的健康日本女性进行了横断面调查，以检验 FSFI-J 的心理测量可靠性和有效性。使用组内相关系数（ICC）和克朗巴赫 α 系数分别进行了测试-重测和内部一致性的可靠性研究。进行了有效性研究，包括表面效度、结构效度、同时效度和判别效度。
主要结果是 FSFI-J 的心理测量可靠性和有效性。
FSFI-J 显示出较高的测试-重测可靠性（ICC > 0.78）和较高的内部一致性（克朗巴赫 α > 0.84）。在表面效度方面，FSFI-J 被认为是可以理解的，可以充分测量女性性功能的各个方面。关于结构效度，FSFI-J 的探索性因子分析支持五因素解决方案，包括欲望/唤起、润滑、性高潮、满意度和疼痛。该域结构与原始 FSFI 相同。关于同时效度，FSFI-J 的总分和域得分与围绝经期主观症状量表的性功能域和视觉模拟量表测量的整体性满意度呈显著相关性（总分 Pearson's r = -0.613）。对于判别效度，在总分和所有子域得分中，规律月经组的 FSFI-J 得分明显高于绝经组，除性满意度外。
FSFI-J 是一种有效的、可靠的工具，可用于测量处于伴侣关系中的健康日本女性性功能的多维方面。
