“…For example, measuring adherence of a complicated universal procedure such as SWPBS (http://www.pbis.org) requires attention to planning behaviors of staff across time, examination of the behavior of principals, resources employed, physical changes across a building, knowledge of staff and students, assessment of the degree to which individual students receive parts of the intervention, lesson plans, and so on. A simple (relative to SWPBS) classroom management intervention may just require changes in the verbal behavior of teachers within a discrete daily period (Boat et al, 2009;Casey & McWilliam, 2008). Regardless, the first step for any adherence measurement is operationally defining the intervention linked to targeted variables and settings.…”
