Changing in the sexual function is an important condition in women with gynecological cancers. A valid and reliable questionnaire is required to assess this condition. The aim of this study was to translate and validate the Persian version of the Sexual-Vaginal Function Changes Questionnaire (SVQ) in women with gynecologic cancers.
This methodological study with a psychometric design was conducted on 250 women with gynecologic cancers, who visited public and private medical centers in Tehran to receive follow-up services. Convenience sampling was conducted from April 2019 to May 2020. First, the Persian version of the Sexual Function-Vaginal Changes Questionnaire was developed and then, psychometric properties such as content validity, face validity, construct validity and criterion validity were assessed. Reliability of the instrument was assessed by Cronbach's alpha coefficient.
Mean age of participants was 53.3 ± 11.8 and mean score of SVQ was 63.0 ± 9.1 in the possible range of 26-104. Content validity was tested through qualitative method and six items were revised as suggested by the expert panel. Cronbach's alpha coefficient was 0.71 for the whole questionnaire and it was 0.93, 0.92, 0.89, 0.78, 0.88 and 0.78 for the 6 subscales, respectively, which shows the optimal internal consistency. Results of exploratory factor analysis revealed six factors as (1) intemacy and sexual interst, (2) arousal, (3) changes in intemacy and sexual interst after cancer, (4) vaginal changes after cancer, (5) vaginal bleeding during coitus, (6) and sexual worry and dissatisfaction after cancer. explained 70.09% of the variance observed. Criterion validity test of the questionnaire showed a significant correlation between the total SVQ scores and the total Female Sexual Function Index (FSFI) scores as well as between SVQ dimensions and dimensions of FSFI (P < 0.001).
The findings from this study indicated that the Persian version of the SVQ is a valid and reliable instrument to assess sexual function-vaginal changes in women with gynecologic cancers.
妇科癌症患者的性功能改变是一个重要的状况。需要使用有效的、可靠的问卷来评估这种状况。本研究的目的是翻译并验证妇科癌症患者的性-阴道功能变化问卷（SVQ）的波斯语版本。
这是一项具有心理测量学设计的方法学研究，共纳入 250 名在德黑兰的公立和私立医疗中心接受随访服务的妇科癌症患者。便利抽样于 2019 年 4 月至 2020 年 5 月进行。首先，开发了性功能-阴道变化问卷的波斯语版本，然后评估了其心理测量学特性，如内容效度、表面效度、结构效度和效标效度。使用 Cronbach's alpha 系数评估了该工具的信度。
参与者的平均年龄为 53.3±11.8 岁，SVQ 的平均得分为 63.0±9.1，得分范围为 26-104。内容效度通过定性方法进行了测试，根据专家小组的建议对 6 个项目进行了修订。整个问卷的 Cronbach's alpha 系数为 0.71，6 个分量表的 Cronbach's alpha 系数分别为 0.93、0.92、0.89、0.78、0.88 和 0.78，表明具有最佳的内部一致性。探索性因子分析结果显示，有 6 个因子，分别为（1）亲密感和性兴趣，（2）唤起，（3）癌症后亲密感和性兴趣的变化，（4）癌症后阴道变化，（5）性交时阴道出血，（6）癌症后性担忧和不满。解释了观察到的方差的 70.09%。问卷的效标效度检验表明，SVQ 总分与女性性功能指数（FSFI）总分之间以及 SVQ 维度与 FSFI 维度之间均存在显著相关性（P<0.001）。
本研究表明，SVQ 的波斯语版本是一种有效且可靠的工具，可用于评估妇科癌症患者的性-阴道功能变化。
