To validate the six-item female sexual function index (FSFI-6) in middle-aged Brazilian women.
Cross-sectional observational study, involving 737 (premenopausal = 117, perimenopausal = 249, postmenopausal = 371) Brazilian sexually active women, aged between 40 and 55 years, not using hormonal contraceptive methods. The Brazilian FSFI-6 was developed from the translation and cultural adaptation of the Portuguese FSFI-6 version. The participants completed a general questionnaire, the FSFI-6, and the menopause rating scale (MRS). The validation was performed by AMOS 16.0 software (SPSS, Inc., Chicago, IL, USA) for a confirmatory factor analysis (CFA). The chi-square of degrees of freedom (χ2/df), the comparative fit index (CFI), the Tucker-Lewis index (TLI) and the root-mean-square error of approximation (RMSEA) were used as indices of goodness of fit. Cronbach α coefficient was used for internal consistency.
The process of cultural adaptation has not altered the Brazilian FSFI-6, as compared with the original content. The CFA for the FSFI-6 score showed an acceptable fit (χ2/df = 3.434, CFI = 0.990, TLI = 0.980, RMSEA = 0.058, 90% confidence interval (90%CI) = 0.033-0.083, ≤ 0.001) and a good reliability was established in FSFI-6 and MRS (Cronbach α = 0.840 and = 0.854, respectively). In addition, 53.5% of the sample had low sexual function.
The FSFI-6 was translated and adapted to the Brazilian culture and is a consistent and reliable tool for female sexual dysfunction screening in Brazilian middle-aged women.
验证巴西中年女性的六项女性性功能指数（FSFI-6）。
横断面观察性研究，纳入737名年龄在40至55岁之间、未使用激素避孕方法的巴西性活跃女性（绝经前=117名，围绝经期=249名，绝经后=371名）。巴西FSFI-6是通过对葡萄牙语FSFI-6版本进行翻译和文化调适而制定的。参与者完成了一份一般问卷、FSFI-6和更年期评定量表（MRS）。使用AMOS 16.0软件（美国伊利诺伊州芝加哥市SPSS公司）进行验证性因子分析（CFA）。自由度的卡方值（χ2/df）、比较拟合指数（CFI）、塔克-刘易斯指数（TLI）和近似均方根误差（RMSEA）用作拟合优度指标。使用克朗巴赫α系数评估内部一致性。
与原始内容相比，文化调适过程未改变巴西FSFI-6。FSFI-6评分的CFA显示拟合度可接受（χ2/df = 3.434，CFI = 0.990，TLI = 0.980，RMSEA = 0.058，90%置信区间（90%CI）= 0.033 - 0.083，≤ 0.001），并且在FSFI-6和MRS中建立了良好的信度（克朗巴赫α分别为0.840和0.854）。此外，53.5%的样本性功能低下。
FSFI-6已被翻译并适用于巴西文化，是巴西中年女性性功能障碍筛查的一种一致且可靠的工具。
