To investigate the motivation of pregnant women towards the practice of pelvic floor exercises during pregnancy using the revised Theory of Planned Behaviour (RTPB), incorporating measures of past behaviour.
Longitudinal cohort study.
Women (n= 289) attending antenatal clinics in the North-East of Scotland were interviewed in the third trimester of pregnancy regarding their practice of pelvic floor exercises. Beliefs and attitudes about the exercises were investigated by self-administered questionnaire using the RTPB as a framework. A follow-up postal questionnaire was sent between 6 and 12 months after delivery.
TPB variables (attitude, subjective norm, and self-efficacy) explained 53.1% of the variance in intention to practise pelvic floor exercises during pregnancy. Perceived vulnerability to incontinence (attitude to the current behaviour) had no relationship with intention. Measures of past behaviour significantly improved the percentage of explained variance in intention. Confidence in ability to perform pelvic floor exercises correctly (self-efficacy) reliably predicted subsequent practice.
Future compliance with pelvic floor exercises may be enhanced by effective instruction to enhance confidence in ability to contract the correct muscles and promotion of measures to help establish a habit of exercising the pelvic floor muscles.
使用修订后的计划行为理论（RTPB），结合过去行为的测量，探讨孕妇在怀孕期间进行骨盆底运动的动机。
纵向队列研究。
在苏格兰东北部的产前诊所，对 289 名孕妇在妊娠晚期进行了访谈，询问了她们进行骨盆底运动的情况。通过自我管理问卷，使用 RTPB 作为框架，调查了对运动的信念和态度。在分娩后 6 至 12 个月之间，寄发了后续的邮寄问卷。
TPB 变量（态度、主观规范和自我效能）解释了 53.1%的怀孕期间进行骨盆底运动的意图。对尿失禁的易感性（对当前行为的态度）与意图没有关系。过去行为的测量显著提高了意图的解释方差百分比。正确进行骨盆底运动的能力的信心（自我效能）可靠地预测了随后的练习。
通过有效的指导，增强对正确收缩肌肉的能力的信心，并促进有助于建立骨盆底肌肉锻炼习惯的措施，可能会提高未来对骨盆底运动的依从性。
