目的 根据行为的“能力、机会、动机和行为”（COM-B）模型，对影响产后体力活动（PA）的因素进行行为分析，以利用行为改变轮（BCW）为干预措施的制定提供信息。使用半结构化访谈和定量问卷设计横断面、多方法研究。在英国赫特福德郡和剑桥郡设置儿童中心和母婴小组。参与者对产后妇女的便利样本进行访谈(n=16) 并完成了调查问卷 (n=158)。方法半结构化访谈遵循预先准备的主题指南，探索 COM-B 模型组件，并使用框架分析进行分析。该问卷以行为自我评估问卷为基础，根据患者和公众的参与以及访谈结果进行了调整。问卷调查参与者对与 COM-B 模型组件相关的 22 条预定义陈述的同意程度进行了评分。计算平均值、SD 和 95% CI，并根据重要性对每个项目进行分类。收集了人口统计数据。 结果 调查问卷显示，如果新妈妈有更多的时间、感觉不那么疲劳、有方便的托儿服务、属于某个群体、有医疗保健专业人员的建议、能够养成习惯并且有更多的动力，她们就会更加活跃。定性数据中出现的其他主题包括与其他新妈妈一起参加 PA 小组、复杂分娩后体力有限、社交互动、享受和父母信念作为动机、提供儿童友好的 PA 设施和环境以及婴儿不可预测的日常生活。 结论 本文中提出的行为分析确定并补充了影响目标行为的一系列因素的详细信息。有些是目标人群所特有的，需要对产后妇女进行有针对性的干预措施，而有些则是个体化的，表明需要进行个体化的干预措施。我们将使用所提供的行为分析，通过 BCW 中的后续步骤来设计干预措施。
Objective Develop a behavioural analysis of factors influencing postnatal physical activity (PA) according to the 'capability, opportunity, motivation and behaviour' (COM-B) model of behaviour to inform intervention development using the Behaviour Change Wheel (BCW).Design Cross-sectional, multi-method study using semi-structured interviews and a quantitative questionnaire.Setting Children's centres and mother and baby groups in Hertfordshire and Cambridgeshire, UK.Participants Convenience samples of postnatal women were interviewed (n=16) and completed the questionnaire (n=158).Methods Semi-structured interviews followed a preprepared topic guide exploring the COM-B model components and analysed using framework analysis. The questionnaire, based on the self-evaluation of behaviour questionnaire, was adapted using patient and public involvement and findings from the interviews. Questionnaire participants rated their agreement with 22 predefined statements related to COM-B model components. Mean, SD and 95% CI were calculated and each item categorised according to importance. Demographic data were collected.Results The questionnaire identified that new mothers would be more active if they had more time, felt less tired, had accessible childcare, were part of a group, advised by a healthcare professional, able to develop a habit and had more motivation. Additional themes emerging from qualitative data were engaging in PA groups with other new mothers, limited physical stamina following complicated births, social interaction, enjoyment and parental beliefs as motivation, provision of child-friendly PA facilities and environments and babies' unpredictable routines.Conclusion The behavioural analysis presented in this paper identifies and adds detail on the range of factors influencing the target behaviour. Some are unique to the target population, requiring targeted interventions for postnatal women, whereas some are individualised, suggesting the need for individually tailored interventions. We will use the behavioural analysis presented to design an intervention using the subsequent steps in the BCW.
