The point of this study was looking at additive effects. It appears that pairing mindfulness techniques with behavior management strategies is typically more effective than mindfulness techniques alone.
Another issue would be the maintenance of using these strategies – so ensuring that they continue (as there is limited research to suggest that they changes in behavior continue once mindfulness exercises are stopped).
It also appears more research is needed on why these techniques appear to be more effective for some children than others (and if these relates to behavior functions, such as desire for teacher/peer attention).
Overall, I think teacher/implementer training is important and also that data collection is simplified so that it can be consistently taken.
