Supporting vulnerable families’ meal practices: process evaluation of a nationwide intervention implemented by a retailer and social organizations

Abstract

Abstract Background 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. Methods 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. Results 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. Conclusions 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. Trial registration The study protocol was pre‑registered prior to data collection at Clinicaltrials.gov (NCT05595551–27/10/2022).
