Changes in sexual function can be difficult to capture, especially when an attempt is made to assess the effects of pregnancy or childbirth on the sexual function of first-time mothers. Commonly used sexual function measures are limited and fail to account for pregnancy or birth in assessment of function.
The purpose of this study was to explore the utility of the Sexual Function Questionnaire Medical Impact Scale (SFQ-MIS) in assessing impact of childbirth on sexual function among first-time mothers with infants aged one year or younger.
A total of 255 women completed a cross-sectional, web-based survey. Exploratory factor analysis was utilized to assess the factor structure of the SFQ-MIS scores in this sample. Variations in SFQ-MIS scores based upon participant characteristics were conducted to further evaluate the SFQ-MIS scores.
SFQ-MIS score was the primary measure of interest. Factors related to pregnancy and childbirth, such as mode of delivery, infant date of birth, last menstrual period, need for an episiotomy or perineal stitches, breastfeeding status, and score on the Perceived Stress Scale, were also assessed in order to further evaluate the validity and predictive capacity of the SFQ-MIS.
Results indicated one factor that accounted for 58.27% of the variance in impact on sexual function due to childbirth. Cronbach's α coefficient for all five items was acceptable (0.82). Women who were breastfeeding (P<0.05), those who had received perineal stitches after a vaginal delivery (P<0.05), and those who reported no sexual activity in the past month (P < 0.001) experienced significantly greater impact than those who were not breastfeeding, those who had not required stitches, and those who had been sexually active in the past month.
The SFQ-MIS appears to be a useful and valid indicator of changes in sexual function following childbirth, such as those related to arousal, desire, and orgasm.
性功能的变化很难捕捉，尤其是在试图评估怀孕或分娩对初产妇性功能的影响时。常用的性功能测量方法有限，在评估功能时未能考虑到怀孕或分娩。
本研究旨在探讨性功能问卷医疗影响量表（SFQ-MIS）在评估 1 岁或以下婴儿的初产妇分娩后性功能影响方面的效用。
共有 255 名女性完成了一项横断面、基于网络的调查。采用探索性因素分析评估了该样本中 SFQ-MIS 评分的因子结构。根据参与者特征进行了 SFQ-MIS 评分的变化，以进一步评估 SFQ-MIS 评分。
SFQ-MIS 评分是主要的测量指标。还评估了与妊娠和分娩相关的因素，如分娩方式、婴儿出生日期、末次月经、是否需要会阴切开术或会阴缝合、母乳喂养状态以及感知压力量表的评分，以进一步评估 SFQ-MIS 的有效性和预测能力。
结果表明，一个因素解释了分娩对性功能影响的 58.27%的方差。所有五个项目的克朗巴赫α系数可接受（0.82）。母乳喂养的女性（P<0.05）、阴道分娩后接受会阴缝合的女性（P<0.05）以及过去一个月无性行为的女性（P < 0.001）经历的影响明显大于未母乳喂养、未缝合以及过去一个月有性行为的女性。
SFQ-MIS 似乎是评估分娩后性功能变化的有用且有效的指标，例如与唤起、欲望和性高潮相关的变化。
