Abstract

Background: 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. Methods: 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. Results: 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). Conclusions: 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. © 2022, The Author(s).
