This study examined the impact of healthy and unhealthy primes on the food choice of restrained and unrestrained eaters. Based on a literature review it was hypothesized that restrained eaters would be more susceptible to healthy primes. The reason for this hypothesis was that healthy primes would serve as a reminder of their diet and therefore promote healthy eating. To test the hypothesis, an experiment was carried out involving priming 92 subjects via posters with pictures of either healthy or unhealthy snacks. Participants were then asked about the food they purchased. The formulated hypothesis was confirmed since the results showed that indeed restrained eaters were more affected by the healthy prime than the unrestrained eaters. This result is in line with current studies. Moreover, unrestrained eaters were affected by the unhealthy prime, which was not the case for restrained eaters. Together these findings suggest that people are more responsive to primes that are congruent with their dietary constraints.

This research study tested an intervention, based on autonomous teams and the service co-creation approach, to improve the social inclusion and self-determination (as indicators of quality of life) of people with intellectual disability. Members of the autonomous teams (professionals, people with intellectual disability, and family members) cooperated to plan and carry out a project. A total of 72 autonomous teams participated (experimental condition). Each team designed its action plan to be implemented during eight weeks. Three measurement times were used: before the intervention (T1), four (T2) and eight (T3) weeks after the starting point. Family members (experimental group, N = 117; control group, N = 187) reported on the social inclusion and self-determination of their relative with intellectual disability. Scores in the control group remained stable over time, whereas scores in the experimental group changed significantly. Social inclusion increased (T2), and later stabilized (T3). By contrast, self-determination increased (T2), but this improvement was subsequently reduced (T3).
