The Female Sexual Function Index (FSFI) has been validated for use in many countries. It has been used for clinical and research purposes in Sweden, but the reliability and validity of the Swedish version have never been tested.
The aim of this study was to investigate the psychometric properties of the Swedish version of the FSFI.
After informed consent, 50 women with a diagnosis of hypoactive sexual desire disorder (HSDD) and 58 age-matched healthy volunteers completed the questionnaires.
Reliability was tested by Cronbach's alpha and test-retest by Pearson's correlation, convergent validity by correlation of the FSFI and the Sexual Function Questionnaire (SFQ), divergent validity by correlation of FSFI and the Symptoms Checklist-90-Revised (SCL-90-R), and discriminant validity by Student's t-test and chi-square test to assess differences between women with and without HSDD.
Cronbach's alpha was 0.90-0.96 and test-retest reliability was good (r=0.86-0.93) for all domains in the whole sample; reliability was low for lubrication and pain in the control group. Correlations between all corresponding domains of the FSFI and the SFQ were high for the whole sample (r=0.74-0.87) and moderate to high for both the clinical and the control group. There was no correlation between most FSFI domains and the SCL-90-R. Discriminant validity was very good for each of the FSFI domains (P=0.001, t=7.05-15.58), although the controls reported relatively low scores on the desire domain. The total FSFI score was 31.37 (standard deviation [SD] 2.66) for the clinical group and 17.47 (SD 5.33) for the controls (P=0.001, t=15.99).
The Swedish version of the FSFI can be used as a validated and reliable instrument for assessing sexual function in women with HSDD.
女性性功能指数（FSFI）已在许多国家得到验证可用于临床。它已在瑞典用于临床和研究目的，但瑞典语版本的信度和效度从未经过测试。
本研究的目的是调查瑞典语版FSFI的心理测量特性。
在获得知情同意后，50名被诊断为性欲减退障碍（HSDD）的女性和58名年龄匹配的健康志愿者完成了问卷调查。
通过Cronbach's α系数检验信度，通过Pearson相关系数检验重测信度，通过FSFI与性功能问卷（SFQ）的相关性检验收敛效度，通过FSFI与症状自评量表-90修订版（SCL-90-R）的相关性检验区分效度，并通过学生t检验和卡方检验评估有无HSDD的女性之间的差异。
整个样本中所有领域的Cronbach's α系数为0.90 - 0.96，重测信度良好（r = 0.86 - 0.93）；对照组中润滑和疼痛领域的信度较低。整个样本中FSFI和SFQ所有相应领域之间的相关性较高（r = 0.74 - 0.87），临床组和对照组的相关性为中度至高度。大多数FSFI领域与SCL-90-R之间无相关性。尽管对照组在性欲领域的得分相对较低，但FSFI每个领域的区分效度都非常好（P = 0.001，t = 7.05 - 15.58）。临床组的FSFI总分是31.37（标准差[SD] 2.66），对照组是17.47（SD 5.33）（P = 0.001，t = 15.99）。
瑞典语版FSFI可作为评估患有HSDD女性性功能的经过验证且可靠的工具。
