简要总结
The aim of this study is to conduct an outcome and process evaluation of the REWARD intervention, a serious game intervention using reward-based strategies as a main method to trigger healthy snacking in Flemish adolescents.
详细描述
As a high intake of energy-dense snacks is common in adolescents and has been related to overweight, the REWARD-project aims to develop and evaluate an intervention focusing on improving adolescents' snacking patterns. Since healthy nutrition promoting strategies used until now had limited effects, the REWARD-project proposes a paradigm shift: the development of an innovative framework to facilitate healthy food choices in adolescents by introducing the concept of reward sensitivity (RS) to explain food choices and using reward-based strategies in a serious game intervention.
1.1 General aim and objectives of the evaluation study
The aim of this study is to conduct an outcome and process evaluation of the REWARD intervention, a serious game using reward-based strategies as a main method to trigger healthy snacking in Flemish adolescents.
- To assess if a serious game rewarding healthy food choices improves the healthy snack intake (i.e., measured with a healthy snack index) in 14- to 16-year old Flemish adolescents.
- To assess if adolescents' reward sensitivity moderates the effect of the intervention on the healthy snack index of consumed snacks.

结局指标
主要结局
Change in the Healthy Snacking Index
时间窗: The outcome will be measured at the baseline (before start intervention), posttest (1-7 days after the intervention end)
A healthy snacking index will be calculated based on a Food Frequency Questionnaire (FFQ). Snacks are in this study defined as all food items consumed outside (\>30 min) of breakfast, lunch and dinner. The daily intake of each FFQ category will be obtained by multiplying the frequency of consumption with the quantity of consumption per week (g) divided by 7. These daily intakes will then be summed to obtain the daily intake of healthy snacks (g), and unhealthy snacks (g). The classification of snacks and drinks into healthy and unhealthy is based on the nutrient profiling model as developed by the UK NP Ofcom model (Lobstein et al. 2009). Finally a health index for snacks will be calculated: (gram healthy snacks / (gram healthy snacks + gram unhealthy snacks))\*100.
