The 'Primary Care SHOPping Intervention for Cardiovascular Disease Prevention' (PCSHOP) trial tested the effectiveness and feasibility of a behavioural intervention to reduce saturated fat in food purchases. The intervention offered feedback from data collected through a supermarket loyalty card to supplement brief advice from a nurse. This qualitative study aimed to describe participants' experiences of receiving this intervention.
We conducted semi-structured, one-to-one, telephone interviews with participants from the PCSHOP trial. Interviews were audio-recorded and transcribed verbatim. We employed the one sheet of paper technique and a thematic analysis to develop high-level themes in NVivo software.
Twenty-four participants were interviewed (mean age: 63 years (SD 12)). They reported that the brief advice did not provide any new information but they welcomed the sense of accountability the nurse provided. The personalised shopping feedback and healthier swap suggestions provided novel information that challenged previously held beliefs about the saturated fat content of food purchases and encouraged some positive dietary changes. However, the taste preferences of the participant or other household members were a barrier to changing food shopping behaviours.
Harnessing loyalty card data is a novel and acceptable method to offering personalised dietary feedback. Yet, issues on the suitability of the healthier swap suggestions limited the extent of dietary change.

“初级保健 SHOPping 干预心血管疾病预防”（PCSHOP）试验测试了一种行为干预措施减少食物购买中饱和脂肪的有效性和可行性。该干预措施提供了通过超市会员卡收集的数据反馈，以补充护士的简短建议。本定性研究旨在描述参与者接受这种干预的经验。
我们对 PCSHOP 试验的参与者进行了半结构化的一对一电话访谈。访谈进行了录音，并逐字记录。我们在 NVivo 软件中使用一页纸技术和主题分析来开发高层次主题。
对 24 名参与者进行了访谈（平均年龄：63 岁（SD 12 岁））。他们报告说，简短的建议没有提供任何新信息，但他们欢迎护士提供的责任感。个性化的购物反馈和更健康的交换建议提供了新的信息，挑战了他们以前对食物购买中饱和脂肪含量的看法，并鼓励了一些积极的饮食改变。然而，参与者或其他家庭成员的口味偏好是改变购物行为的障碍。
利用会员卡数据是提供个性化饮食反馈的一种新颖且可接受的方法。然而，更健康的交换建议的适用性问题限制了饮食改变的程度。
