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.

Procedural fidelity is defined as the extent to which the independent variable is implemented as prescribed. Research using computerized tasks has shown that fidelity errors involving consequences for behavior can hinder skill acquisition. However, studies examining the effects of these errors once skills have been mastered are lacking. Thus, this translational study investigated the effects of varying levels of fidelity following mastery of a computerized arbitrary matching-tosample task. A group design (consisting of five groups) was used in which college students initially completed 250 trials during which no programmed errors (i.e., perfect fidelity) were arranged, followed by an additional 250 trials with consequences delivered across various levels of fidelity (i.e., 20, 40, 60, 80, and 100% of trials administered without errors). The results showed that participants assigned to higher fidelity conditions performed better (on average). These results extended the findings of previous studies by demonstrating how errors involving consequences affect behavior across various stages of learning.
