Teachers are often asked to self-report treatment integrity data. However, when self-report responses are compared with those from a direct observer, it is apparent that teachers commonly overestimate the extent to which an intervention was implemented as planned. As such, more research related to teacher self-report to assess treatment integrity is needed. The objective of this preliminary single-case multiple-baseline design study was to improve interrater agreement between observers¡¯ and teachers¡¯ self-report ratings of treatment integrity by providing teachers with comprehensive, direct training (including an intervention description, modeling, practice, and feedback). Results indicate that after this training, agreement between observers¡¯ and teachers¡¯ ratings of treatment integrity improved %K treatment integrity %K self-report %K interrater agreement %U https://journals.sagepub.com/doi/full/10.1177/1534508417738721
