A Cafeteria Personnel Intervention to Improve the School Food Environment.

In this study, we examined the impact of an intervention targeting food service personnel on Smarter Lunchroom adherence in school cafeterias. This study used a quasi-experimental design, conducted in a Virginia school district serving predominantly African-American children, all eligible for free meals. In 2014-15, cafeteria managers (N = 38) from 43 schools were trained (and tasked with training their staff) on principles of behavioral economics and choice architecture designed to enhance students' food selections via modifications to the cafeteria environment.
