The association between radiotherapy for gynecological carcinoma and sexual dysfunction is well established. Regular vaginal dilation is widely recommended to these women as a way for them to maintain vaginal health and good sexual functioning. However, the compliance rate with this recommendation is low. The purpose of this study was to test the effectiveness of a group psychoeducational program based on the "information-motivation-behavioral skills" model of behavior change in increasing the rate of compliance.
Thirty-two women with Stage I or II cervical or endometrial carcinoma who were being treated with radiotherapy were randomized and received either the experimental group program or the control intervention that consisted of written information and brief counseling. Outcome measures included global sexual health, knowledge about sexuality and cancer, fears about sexuality after cancer, and vaginal dilation compliance.
Younger women attending the experimental program (44.4%) were significantly more likely to follow recommendations for vaginal dilation than those who received the control intervention (5.6%). Women, regardless of age, who received the experimental intervention reported less fear about sex after cancer treatment. The older women who received the experimental intervention gained more sexual knowledge. There was no evidence that the experimental intervention improved global sexual health.
This is the first controlled study to provide evidence of an intervention's effectiveness 1. in increasing women's vaginal dilation following radiotherapy for gynecological carcinoma and 2. in reducing their fears about sex after cancer. Most women, particularly younger women, are unlikely to follow the recommendation to dilate unless they are given assistance in overcoming their fears and taught behavioral skills.
妇科癌症放疗与性功能障碍之间的关联已得到充分证实。常规阴道扩张术被广泛推荐给这些女性,作为维持阴道健康和良好性功能的一种方式。然而,这一建议的依从率较低。本研究的目的是检验基于行为改变的“信息-动机-行为技能”模型的团体心理教育项目在提高依从率方面的有效性。
32名接受放疗的I期或II期宫颈癌或子宫内膜癌女性被随机分组,分别接受实验组项目或由书面信息和简短咨询组成的对照干预。结局指标包括总体性健康、性与癌症知识、癌症后对性的恐惧以及阴道扩张依从性。
参加实验组项目的年轻女性(44.4%)比接受对照干预的女性(5.6%)更有可能遵循阴道扩张建议。接受实验干预的女性,无论年龄大小,在癌症治疗后对性的恐惧都较少。接受实验干预的老年女性获得了更多性知识。没有证据表明实验干预改善了总体性健康。
这是第一项对照研究,为以下干预效果提供了证据:1. 提高妇科癌症放疗后女性的阴道扩张率;2. 减轻她们癌症后对性的恐惧。大多数女性,尤其是年轻女性,除非在克服恐惧方面得到帮助并学到行为技能,否则不太可能遵循扩张建议。
