“…The evidence base of the PBIS is extensive, and is related to positive behavioral, academic, and organizational outcomes (Bradshaw et al, 2010 , 2012 ; Horner et al, 2010 ; Solomon et al, 2012 ; Gage et al, 2018 ; Mitchell et al, 2018 ). However, the effectiveness of PBIS is dependent on the quality of its implementation (Bradshaw et al, 2008 ; Horner et al, 2010 ; Dix et al, 2012 ; Flannery et al, 2014 ; McIntosh et al, 2014 ; Sørlie et al, 2018 ). In fact, schools have been shown to vary widely in their fidelity to and implementation rates of the approach (Buzhardt et al, 2006 ; Lee and Gage, 2020 ), and there is often a gap between research and practice when preventive programs are implemented in schools (Wandersman et al, 2008 ).…”
