1. Objectifs

Intentions :
«The main objective of the current study was to conduct a process evaluation of the healthy eating blog trial in order to gain a deeper understanding as to why the blog had a null impact on food-related outcomes and how mothers perceived the intervention.» (p. 2690)

2. Méthode

Échantillon/Matériau :
«The healthy eating blog trial was conducted with adult mothers of 2–12-year-old children and living in the Quebec City metropolitan area. Mothers had to be primarily responsible for food purchase and preparation in the household and consume fewer than the recommended daily servings of vegetables and fruit and/or of milk and alternatives food groups in the Canadian dietary guidelines in force when the study was initiated on a recalled day […].» (p. 2691) The final sample was of 84 mothers. «The intervention was conducted over a 6-month period at a dose of one weekly blog post written by an RD [registered dietitian] published on the blog for a total of twenty-six blog posts. […] The RD-blogger […] was a female PhD student in nutrition with a 5-year experience as a healthy eating blogger.» (p. 2691) The authors also analyzed «[a] total of 213 comments written by twenty-six mothers (of the forty-two mothers randomised to the intervention group) on the blog during the intervention […].» (p. 2693)

3. Résumé

First, the results of the study «suggest that the blog was perceived as an acceptable and useful tool to deliver a dietary intervention. However, findings also highlighted the complexity for intervention developers and behavioural researchers to design a blog that will respond to the needs of all users. Indeed, although several characteristics of the blog were highly appreciated by the participants (e.g. the nutritional information and the recipes shared by the RD-blogger), there were mixed reactions for other aspects of the blog (e.g. the content of blog posts and the duration of the intervention). […] Second, meal planning and preparation skills were identified as important assets to improve the consumption of vegetables and fruit and milk and alternatives in mothers and their children. Findings also showed that time constraints strongly influenced mothers’ perceived abilities and motivation to adopt a healthier diet. Time constraints also negatively impacted mothers’ engagement with the blog.» (p. 2699)
