Effectively implementing healthy and sustainable food practices in out-of-home food service locations: The perspective of the catering staff members

Abstract

Restaurants, canteens, residential care, hospitals and other out-of-home food service locations can play an important role in improving people's diet quality by offering healthier and more sustainable food choices. However, the effectiveness of implementing sustainable and healthy food practices at these locations is, at least partly, dependent on the extent to which they are accepted and implemented by the staff members. This study aims to assess staff members' motivation, perceived capability, perceived opportunity and their readiness to change their behaviour (i.e., stages of change) in offering more healthy and sustainable food options to their customers or patients. Eleven out-of-home locations that wanted to adjust their assortment towards more healthy and sustainable product offerings participated in this study and were able to distribute a comparable questionnaire among their staff members to assess their perceived readiness to change. Results among 268 participants show that staff members find both a healthy and sustainable food assortment important and also seem to be motivated to improve their food assortment regarding health and sustainability. Perceived opportunity seems to be the largest barrier for staff members, although there is also room for improvement regarding their perceived capability. In addition, personal motivation seems to play the dominant role in staff members' readiness to change the health of the assortment, whereas perceived capability seems to play the dominant role in their perceived readiness to change the sustainability of the assortment. This study shows that taking into account the perspective of the catering staff members may help to effectively implement healthy and sustainable food practices in out-of-home food service locations.
