Lower socioeconomic status (SES) is associated with poorer dietary habits and fewer family meals. Therefore, initiatives to empower families with a lower SES to adopt healthier meal practices are employed. The objective of this study was to evaluate a nationwide intervention "Dinner is served at 1-2-3 euros", developed by a Belgian retailer in collaboration with social organizations. It targets families with a lower SES and aims to promote more balanced and freshly cooked meals by providing recipe booklets of affordable meals at a guaranteed price of 1, 2, or 3 euros per portion. The process evaluation aimed to gain insight into the implementation process (Reach, Recruitment, Dose-delivered, Context), the satisfaction with the intervention (Dose-received), and the perceived impact of intervention participation.
A mixed-methods study combining qualitative (i.e., focus groups and individual interviews) and quantitative research (i.e., surveys) was conducted. An interview with the retailer (n = 1), three focus group interviews with the involved social organizations (n = 15), and interviews with participants of "Dinner is served at 1-2-3 euros" (n = 26) were carried out, as well as surveys among these social organizations and participants.
Social organizations were generally satisfied with the project and appreciated the collaboration with the retailer. The main barrier to implement the project was a lack of time to help participants subscribing. Participants appreciated the inspiration from the recipe booklets, and the recipes' ease of preparation, their healthiness, and the variety. However, the recipes were sometimes deemed too exotic for participants' children. Participants also appreciated the budget friendliness, although the price guarantee mechanism of 1, 2 or 3 euros per portion was not always clear. Positive effects were mentioned in areas such as perceived healthy cooking and eating, improved cooking skills and ideas, and reduced financial concerns.
In general, participants and social organizations were satisfied with the delivery and implementation of the intervention. Participants also noted some positive effects on their meal practices. Future research should provide insight into the intervention's effectiveness and impact on the healthiness of participants' dietary choices.
The study protocol was pre‑registered prior to data collection at Clinicaltrials.gov (NCT05595551-27/10/2022).
较低的社会经济地位（SES）与较差的饮食习惯和较少的家庭用餐有关。因此，采取了一些举措来增强 SES 较低的家庭采用更健康的饮食方式。本研究的目的是评估一项由比利时零售商与社会组织合作发起的全国性干预措施“Dinner is served at 1-2-3 euros”，该措施针对 SES 较低的家庭，旨在通过提供价格为每道菜 1、2 或 3 欧元的经济实惠食谱，促进更均衡和新鲜的烹饪。过程评估旨在深入了解实施过程（范围、招募、剂量提供、背景）、对干预的满意度（剂量接受）以及干预参与的感知影响。
采用定性（即焦点小组和个人访谈）和定量研究（即调查）相结合的混合方法研究。对零售商进行了一次访谈（n=1），对参与的社会组织进行了三次焦点小组访谈（n=15），对“Dinner is served at 1-2-3 euros”的参与者进行了访谈（n=26），并对这些社会组织和参与者进行了调查。
社会组织对该项目普遍感到满意，并赞赏与零售商的合作。实施该项目的主要障碍是缺乏帮助参与者注册的时间。参与者欣赏食谱册的灵感，以及食谱的易于准备、健康和多样性。然而，对于参与者的孩子来说，一些食谱有时被认为过于异国情调。参与者还赞赏其价格实惠，尽管每道菜 1、2 或 3 欧元的价格保证机制并不总是明确。参与者还提到了一些积极影响，例如认为健康烹饪和饮食、提高烹饪技巧和创意以及减少财务担忧。
总的来说，参与者和社会组织对干预措施的实施和交付感到满意。参与者还注意到他们的饮食方式有一些积极影响。未来的研究应该深入了解干预措施的有效性及其对参与者饮食健康选择的影响。
在数据收集之前，研究方案已在 Clinicaltrials.gov 上预先注册（NCT05595551-27/10/2022）。
