Treatment integrity has cogent implications for intervention effectiveness. Understanding these implications is an important, but often neglected, undertaking in behavior analysis. This paper reviews current research on treatment integrity in applied behavior analysis. Specifically, we review research evaluating the relation between integrity failures and the efficacy of behavioral interventions. Avenues for future research are provided.

Observational learning is an important area in the field of psychology and behavior science more generally. Given this, it is essential that behavior analysts articulate a sound theory of how behavior change occurs through observation. This paper begins with an overview of seminal research in the area of observational learning, followed by a consideration of common behavior analytic conceptualizations of these findings. The interbehavioral perspective is then outlined, shedding light on some difficulties with the existing behavior analytic approaches. The implications of embracing the interbehavioral perspective for understanding the most complex sorts of behavior, including those involved in observational learning are considered.

This study evaluates the effectiveness of a variation of the high-probability (high-p) sequence involving bites of food as high-p tasks on the acceptance of low-probability (low-p) foods in an adolescent with autism spectrum disorder. After demonstrating the effectiveness of the high-p sequence using a reversal design, the participant's mother implemented the intervention. Intervention effects were partially maintained during 7-month maintenance probes. Implications for research and practice are provided.
