Abstract

Objectives

The objective of this paper was to examine the predictors of breastfeeding exclusivity at two time-points (6 and 26 weeks postpartum) using a dyadic mother–father extended model of the theory of planned behaviour.

Design/Method

A sample of 1139 first-time Australian mother–father dyads completed measures of each of the Theory of Planned Behaviour variables (intention, attitudes, subjective norms, and perceived behavioural control) and additional psychosocial and behavioural predictors of breastfeeding, including problems with breastfeeding, psychological distress, childcare stress, partner support, and the frequency and time of first public breastfeed. Confirmatory factor analyses were used to determine the factor structures of the latent constructs to be included in the structural model. Structural equation modelling was used to model pathways between variables.

Results

Breastfeeding exclusivity at 6 weeks was significantly predicted by breastfeeding self-efficacy at 6 weeks, intention to exclusively breastfeed, and frequency of public breastfeeding over the month prior, whereas childcare stress, partner support, time of first public breastfeed, and fathers' variables (attitudes and subjective norms) had little influence. Self-efficacy mediated the relationship between mothers' attitudes, psychological distress, and breastfeeding problems with breastfeeding exclusivity at 6 weeks. Breastfeeding exclusivity at 26 weeks was significantly predicted by mothers' attitudes, self-efficacy, breastfeeding exclusivity at 6 weeks, and frequency of public breastfeeding in the month prior.

Conclusions

The results highlight the importance of breastfeeding self-efficacy and confidence to breastfeed in public as crucial constructs in promoting long-term exclusive breastfeeding and provides support for an extended theory of planned behaviour model in predicting breastfeeding outcomes.

扩展计划行为理论，利用结构方程模型预测澳大利亚母亲-父亲二人组的纯母乳喂养情况。

目的本文的目的是利用计划行为理论的母父二元扩展模型，在两个时间点（产后 6 周和 26 周）对纯母乳喂养的预测因素进行研究：1139 位首次哺乳的澳大利亚母亲-父亲二人组样本完成了对计划行为理论各变量（意向、态度、主观规范和感知行为控制）以及其他社会心理和行为母乳喂养预测因素的测量，包括母乳喂养问题、心理困扰、育儿压力、伴侣支持以及首次公开母乳喂养的频率和时间。确认性因子分析用于确定将纳入结构模型的潜在构念的因子结构。结构方程模型用于建立变量之间的路径模型：结果：6周时的纯母乳喂养受6周时的母乳喂养自我效能感、纯母乳喂养意愿和前一个月的公开母乳喂养频率的显著预测，而育儿压力、伴侣支持、首次公开母乳喂养时间和父亲变量（态度和主观规范）的影响很小。自我效能感在母亲的态度、心理困扰和母乳喂养问题与 6 周时母乳喂养排他性之间起到了中介作用。母亲的态度、自我效能感、6 周时的母乳喂养排他性以及前一个月的公开母乳喂养频率对 26 周时的母乳喂养排他性有显著的预测作用：研究结果强调了母乳喂养自我效能感和在公共场合母乳喂养的信心对于促进长期纯母乳喂养的重要性，并为预测母乳喂养结果的扩展计划行为理论模型提供了支持。
