Increasing teacher treatment integrity of behavior support plans through consultation and implementation planning.

School psychologists commonly provide intervention services to children through consultation with teachers. Data suggest, however, that many teacher consultees struggle to implement these interventions. There are relatively few evidence-based strategies for promoting teacher consultees' intervention implementation. The purpose of this study was to evaluate Implementation Planning as a strategy for increasing the adherence and quality with which teacher consultees implemented behavior support plans. Implementation Planning involves adapting intervention steps to the implementation context, providing detailed logistical planning, as well as identifying implementation barriers and developing strategies to address them. Results indicated that teachers' implementation adherence levels increased and quality levels increased with corresponding decreases in variability, compared to standard behavioral consultation. Implications for future research on treatment integrity are discussed.
