- Public TitleGame ON: Investigating the effect of a health game on automatic associations towards unhealthy food
- Scientific TitleGame ON: Investigating the impact of a health game on implicit attitude towards food
- ACRONYM
- hypothesisThe effectiveness of a health game based on an Evaluative Conditioning paradigm compared to a control game will be tested in a Dutch sample of adolescents. It is expected that the adolescents in the intervention condition will show a increased healthy implicit attitude towards food, caused by a stronger positive association towards healthy food, a stronger negative association towards unhealthy food, or a combination of both. Furthermore expected is a decreased liking and craving of unhealthy food, and a healthier food choice at an immediate follow-up, compared to the control group.

- Target number of participants100
- InterventionsAdolescents with overweight or obesity are randomly assigned to the experimental or control condition, resulting in two conditions.
1. The first condition, ‘Health game Sky Islands’, will consist of a single session of the health game, and pre- and post assessment of the implicit attitude using an IAT test.
2. The second condition, ‘Control game Sky Islands’, will consist of a single session of the control game, and pre- and post assessment of the implicit attitude using an IAT test.
- Primary outcomeImplicit attitude towards food (Greenwald, 1998).
- Secondary outcome1. Explicit attitude towards food (liking and craving, measured on a visual analogue scale).
2. Food behaviour 1; effort to acquire food (measured with a digital snack dispenser paradigm designed by van Koningsbruggen, G.M., Veling, H., Stroebe, W. & Aarts, H. (2014))
3. Food behaviour 2; virtual food choice (measured with a digital food choice question).
- Timepoints1. Pretest (all primary and secondary outcomes);
2. Posttest (all primary and secondary outcomes), immediately after Game play

- Brief summaryThe effectiveness of a health game based on an Evaluative Conditioning paradigm compared to a control game will be tested in a Dutch sample of adolescents. Adolescents are randomly assigned to one of two conditions, either playing the health game or the control game. Implicit attitude and explicit measures will be measured prior to and directly after a 10-minute Game play session. It is expected that the adolescents in the intervention condition will show an increased healthy implicit attitude towards food, and decreased liking and craving of unhealthy food at the second measurement, compared to the control group. The participants in the experimental conditions are furthermore expected to display healthier behaviour directly after game play in terms of effort to acquire food and virtual food choice compared to those playing the control game.
