The theory of planned behaviour (TPB) was employed to investigate infant feeding intentions and subsequent behaviour in women from selected areas of economic hardship in the UK. Underlying beliefs were examined in order to inform future interventions aimed at increasing breastfeeding uptake among women living in such areas, which is associated with low rates of breastfeeding.
Midwives recruited women from areas meeting study criteria. TPB measures were obtained from 303 primiparas via postal questionnaires completed during pregnancy, and feeding method was subsequently obtained from 286 of these women.
A model containing age, education, deprivation, attitude, subjective norm (SN), and perceived behavioural control (PBC) predicted intention to breastfeed (R(2)=.44) and intention to formula feed (R(2)=.45). A model controlling for age, education and deprivation predicted ever having breastfed (86.1% correctly classified) and ever having formula fed (77.1% correctly classified). MANCOVAs differentiated those who intended to breastfeed and subsequently did (inclined actors), those who intended to breastfeed but did not (inclined abstainers), and those who did not intend to breastfeed and did not (disinclined abstainers). Differentiating outcome beliefs, normative beliefs, and control beliefs are presented.
The TPB provided a useful framework with which to examine the factors underlying breastfeeding intentions and behaviour amongst primiparas. A grouping system based on the congruence between intentions and subsequent behaviour revealed important differences between beliefs of the three groups. Further research might usefully test the effectiveness of interventions targeting the beliefs identified here in increasing breastfeeding uptake and duration.
运用计划行为理论(TPB)调查英国经济困难特定地区女性的婴儿喂养意愿及后续行为。对潜在信念进行了研究,以便为未来旨在提高此类地区女性母乳喂养率的干预措施提供信息,该地区母乳喂养率较低。
助产士从符合研究标准的地区招募女性。通过孕期填写的邮政问卷从303名初产妇中获取TPB测量值,随后从其中286名女性那里获取喂养方式。
一个包含年龄、教育程度、贫困程度、态度、主观规范(SN)和感知行为控制(PBC)的模型预测了母乳喂养意愿(R² = 0.44)和配方奶喂养意愿(R² = 0.45)。一个控制了年龄、教育程度和贫困程度的模型预测了曾经进行母乳喂养的情况(正确分类率为86.1%)和曾经进行配方奶喂养的情况(正确分类率为77.1%)。多变量协方差分析区分了那些打算母乳喂养且随后进行了母乳喂养的人(倾向行动者)、那些打算母乳喂养但未进行的人(倾向弃权者)以及那些不打算母乳喂养且未进行的人(不倾向弃权者)。展示了区分结果信念、规范信念和控制信念的情况。
TPB为研究初产妇母乳喂养意愿和行为背后的因素提供了一个有用的框架。基于意愿与后续行为一致性的分组系统揭示了三组信念之间的重要差异。进一步的研究可能会有效地测试针对此处确定的信念的干预措施在提高母乳喂养率和持续时间方面的有效性。
