“…For example, one study presented a theoretical framework of the social ecological model, which classified the food influencers toward a healthy school environment into five categories: (1) students, (2) role models (e.g., peers, family members, and teachers), (3) community (e.g., schools), (4) institutions (e.g., vending suppliers and retailers), and (5) public policymakers (Suarez‐Balcazar et al ., 2007). Recently, several attempts have been made to improve this model, but the contributions are limited in scope (i.e., covering a few stakeholders), theoretical, or based on qualitative data analysis (Ali et al ., 2015; Suarez‐Balcazar et al ., 2018). However, there are no empirical studies adopting a multi‐dimensional perspective to measure the individual or synergistic effects of determinants on the promotion of healthy items and the inter‐relatedness of the different stakeholders.…”
