目的 探讨基于系统交互模型的二元应对干预方案在纯母乳喂养初产妇及配偶中的应用效果，为促进纯母乳喂养率的提高提供经验。方法 采用非同期对照法，便利抽样法选取2024年3-5月的65对初产妇及配偶为对照组，同法选择2024年6-8月的65对为试验组，对照组采取常规护理，试验组在对照组的基础上进行二元应对干预，两组干预时间均为5周。干预结束当天及产后30 d，比较2组初产妇的纯母乳喂养率；干预前、干预结束当天、产后30 d，采用配偶母乳喂养支持量表（the partner breast feeding influence scale，PBIS）、母乳喂养自我效能简式量表（breastfeeding self-efficacy scale short form，BSES-SF）进行调查，比较产妇配偶对母乳喂养的支持程度及初产妇的母乳喂养自我效能。结果 产后30 d，试验组纯母乳喂养48例（80.0%）,高于对照组[36(61.0%)]，差异有统计学意义（χ2=5.163,P=0.023）。两组初产妇配偶的PBIS得分及初产妇的BSES-SF得分在时间、组别及交互效应上的差异均有统计学意义（均P＜0.001）。结论 基于系统交互模型的二元应对干预,能显著提高初产妇配偶对母乳喂养的支持程度、初产妇的母乳喂养自我效能及纯母乳喂养率。

Objective To explore the effect of a dyadic coping intervention program based on the systemic-transactional model in primiparous women and their spouses to promote exclusive breastfeeding and provide insights for improving exclusive breastfeeding rates.Methods A non-synchronous control method was adopted.Convenience sampling was used to select 65 primiparous women and their spouses from March to May 2024 as the control group,and another 65 pairs from June to August 2024 as the experimental group.The former received routine care,while the latter received additional dyadic coping intervention for 5 weeks respectively.The exclusive breastfeeding rates of the 2 groups were compared on the day of intervention completion and 30 days postpartum.The partner breastfeeding influence scale (PBIS) and the breastfeeding self-efficacy scale-short form (BSES-SF) were used to assess the spouses’ support for breastfeeding and the primiparous women’s breastfeeding self-efficacy before the intervention,on the day of intervention completion,and 30 days postpartum.Results At 30 days postpartum,the exclusive breastfeeding rate in the experimental group (48 cases,80.0%) was significantly higher than that in the control group (36 cases,61.0%) (χ2=5.163,P=0.023).The PBIS scores of the spouses and the BSES-SF scores of the primiparous women showed statistically significant differences in time,group,and interaction effects (all P＜0.001).Conclusions The dyadic coping intervention based on the systemic-transactional model significantly improves spouses’ support for breastfeeding,primiparous women’s breastfeeding self-efficacy,and exclusive breastfeeding rates.
