We evaluated internal consistency, test-retest reliability, and criterion validity of the Brazilian Portuguese version of the Female Sexual Function Index 6-item Version (FSFI-6) for postpartum women.
Therefore, questionnaires were applied to 100 sexually active women in the postpartum period. The Cronbach α coefficient was used to evaluate the internal consistency. Test-retest reliability was analyzed by Kappa for each item of the questionnaire and by the Wilcoxon parametric test, comparing the total scores of each evaluation. For the assessment of criterion validity, the FSFI was used as the gold standard and the receiver operating characteristic (ROC) curve was constructed. Statistical analysis was performed using IBM SPSS Statistics for Windows, version 21.0 (IBM Corp., Armonk, NY, USA). It was found that the internal consistency of the FSFI-6 questionnaire was considerably high (0.839).
The test-retest reliability results were satisfactory. It can also be stated that the FSFI-6 questionnaire presented excellent discriminant validity (area under the curve [AUC] = 0.926). Women may be considered as having sexual dysfunction if the overall FSFI-6 score is < 21, with 85.5% sensitivity, 82.2% specificity, positive likelihood ratio of 4.81 and negative likelihood ratio of 0.18.
We conclude that the Brazilian Portuguese version of FSFI-6 is valid for use in postpartum women.
我们评估了巴西葡萄牙语版女性性功能指数 6 项版本（FSFI-6）在产后女性中的内部一致性、重测信度和效标效度。
因此，我们对 100 名产后有性生活的女性进行了问卷调查。采用克朗巴赫 α 系数评估内部一致性。使用 Kappa 分析问卷的每个项目的重测信度，并通过 Wilcoxon 参数检验比较每个评估的总分。为了评估效标效度，FSFI 被用作金标准，并构建了受试者工作特征（ROC）曲线。统计分析使用 IBM SPSS Statistics for Windows，版本 21.0（IBM 公司，纽约州阿蒙克，美国）。研究发现，FSFI-6 问卷的内部一致性相当高（0.839）。
重测信度结果令人满意。FSFI-6 问卷还具有良好的判别效度（曲线下面积[AUC] = 0.926）。如果总 FSFI-6 评分<21，则可以认为女性存在性功能障碍，其灵敏度为 85.5%，特异性为 82.2%，阳性似然比为 4.81，阴性似然比为 0.18。
我们得出结论，巴西葡萄牙语版 FSFI-6 可用于产后女性。
