“…Of the 27 papers included in this review and outlined in Table 1, five employed a qualitative study design [45, 54, 57, 59, 61], nine a quantitative design [42, 44, 48, 50–52, 60, 62, 65], ten utilised mixed-methods [40, 41, 43, 46, 47, 55, 59, 63, 64, 66], and three included summary articles which collated previous findings and discussed lessons learned across multiple publications for a specific intervention [49, 53, 56]. Interventions conducted in the articles were delivered in six high income countries, as categorised by the World Bank [67]: USA [41–44, 48–51, 56, 58, 60, 65, 66], Canada [52, 53, 59], Netherlands [46, 47, 61–64], United Kingdom [45, 57], Australia [40], and Denmark [54, 55]. Further, interventions were conducted in a range of school settings including primary/elementary [40, 42, 44–47, 49, 51, 54–57], middle [43, 48, 66], primary/middle [52, 53, 59], high [58], pre-vocational [61–64], and all ages (primary, middle and high) [41, 50].…”
