ABSTRACT
Treatment integrity is the extent to which procedures are implemented in a manner consistent with their prescribed protocols and is necessary for reaching accurate conclusions regarding functional relations between dependent (i.e., behavior) and independent (i.e., the environment) variables. Several studies assessing the frequency that studies report treatment integrity have been conducted. However, no review has included articles from Behavior Analysis in Practice. Thus, the current study reviewed Behavior Analysis in Practice between 2008 and 2019 to assess the frequency of studies reporting treatment integrity data. A total of 193 articles consisting of 205 studies met the inclusionary criteria for this review. Ninety-six studies (46.83%) reported treatment integrity data, compared to 193 (94.15%) that provided interobserver agreement data. Additionally, 98 studies (47.80%) were considered high risk for treatment implementation inaccuracies. Recommendations and implications for research and practice are discussed.
