DRA contingencies promote improved tolerance to delayed reinforcement during FCT compared to DRO and fixed-time schedules

On the prevalence and magnitude of resurgence during delay-and-denial tolerance teaching

Resurgence is the recurrence of target behavior (e.g., challenging behavior) during a worsening of reinforcement conditions (e.g., increases in response effort, decreases in alternative reinforcement). Previous studies have examined the prevalence and magnitude of resurgence during functional communication training implemented with discriminative stimuli. We conducted a systematic review of the literature to analyze the magnitude and prevalence of resurgence during delay-and-denial tolerance teaching. Similar to previous studies with discriminative stimuli, resurgence occurred for most participants and in about one third of transitions. When resurgence was present, challenging behavior increased to approximately 26% of baseline levels. Resurgence was less likely to occur during response-effort manipulations (i.e., complexity teaching, tolerance-response teaching) and was most likely to occur during increases in delays that ended following the passage of time rather than a response criterion. We discuss implications for treatment refinements and future treatment-relapse research.

Updated Recommendations for Reinforcement Schedule Thinning following Functional Communication Training

Schedule thinning is a necessary treatment procedure following the acquisition of a communication response during functional communication training. In this article, we update and extend the Hagopian et al. Behavior Analysis in Practice, 4, 4-16, (2011) review and recommendations on schedule-thinning procedures following functional communication training. Since their publication, substantial research has been published on the efficacy, efficiency, and social validity of schedule-thinning methods. We provide updated recommendations for schedule thinning based on contemporary literature that has been published since 2011, as well as discuss key areas for future research.

Evaluating the efficacy and generality of a skill-based approach for promoting universal behavioral readiness

Behavioral readiness can take the form of communication and self-control skills during challenging situations that are correlated with the development of problem behavior. A skill-based approach can teach behavioral readiness using procedures that involve synthesized reinforcement, probabilistic reinforcement, and contingency-based delays; however, this approach is commonly used to address severe behavior under specific situations. There is limited research evaluating a skill-based approach to teaching behavioral readiness and addressing emerging problem behavior. Also, it is unclear whether teaching effects under specific situations transfer across other, functionally distinct, situations. We evaluated the generality of a skill-based approach by teaching skills systematically across primary challenging situations involving the interruption of play, presentation of instructions, and removal of reinforcers. Teaching increased communication and self-control skills, and most skills transferred to secondary challenging situations (treatment extension probes) and caregiver-implemented sessions. We discuss challenging situations that required teaching, the generality of teaching, and procedural considerations.

Using Chained or Tandem Schedules With Functional Communication Training: A Systematic Review

Chained and tandem schedules are a common method for thinning schedules of reinforcement following functional communication training (FCT) in the treatment of problem behavior. We conducted a systematic literature review and meta-analysis of chained and tandem schedules following FCT to describe treatment characteristics and evaluate effects. We identified 38 articles and found reductions in problem behavior across four measures. Results of a random-effects multilevel meta-analysis of rigorous evaluations showed a significant effect of chained or tandem schedules + FCT on problem behavior relative to baseline. We observed resurgence in 77% of cases and 31% of schedule-thinning transitions. Results showed chained schedules resulted in greater reductions in problem behavior relative to tandem schedules. Exploratory moderator analyses suggested extinction, combined reinforcement, and delay and denial tolerance training procedures were associated with greater reductions in problem behavior relative to other treatment characteristics. Implications for practice and future research are discussed.

Contingency-based delay to reinforcement following functional communication training for autistic individuals: A multilevel meta-analysis

LAY ABSTRACT

Functional communication training, an intervention for challenging behavior rooted in principles of applied behavior analysis, has copious empirical support dating back to the mid-1980s for autistic individuals. Recently, there has been a concerted effort to thin reinforcement delivery during functional communication training using contingency-based delays that, in turn, are designed to enhance practicality and feasibility while not compromising efficacy. In this synthesis, we meta-analyzed the literature base with the goal of investigating both combined and across type effectiveness of contingency-based delays. We also aimed to investigate moderating variables that might impact intervention outcomes. Findings showed that contingency-based delays were effective for individuals with an autism spectrum disorder diagnosis and most effective when the delay incorporated some form of positive reinforcement. In addition, differential reinforcement of alternative-based delays was overall more effective when compared to differential reinforcement of other behavior-based delays. Noteworthy moderating variables found to impact contingency-based delay efficacy included the intervention dosage and the topography of behavior. We discuss these findings and highlight directions where additional empirical research is warranted to improve our understanding about contingency-based delays for individuals diagnosed with autism spectrum disorder.

Toward trauma-informed applications of behavior analysis

Despite a growing acknowledgement of the importance of understanding the impacts of trauma on therapeutic approaches across human service disciplines, discussions of trauma have been relatively infrequent in the behavior analytic literature. In this paper, we delineate some of the barriers to discussing and investigating trauma in applied behavior analysis (ABA) and describe how the core commitments of trauma-informed care could be applied to behavior analysis. We then provide some examples of how trauma-informed care might be incorporated into ABA practice. We conclude by suggesting opportunities to approach trauma as a viable avenue for behavior analytic research and argue that omitting trauma-informed care from ABA could be detrimental not only to the public perception of ABA, but to the effectiveness of our assessment and treatment procedures.

Increasing passive compliance to wearing a facemask in children with autism spectrum disorder

The current study taught 6 children with autism spectrum disorder (ASD) to increase passive compliance of wearing a facemask across sequentially increasing durations of time. A changing-criterion design embedded within a nonconcurrent multiple baseline design was used to evaluate the effectiveness of a resetting differential reinforcement of other behavior (DRO) without escape extinction procedure on passive compliance. Terminal probe sessions determined DRO fading intervals. Results showed that 2 participants acquired mastery level passive compliance (30 min) without fading during the initial baseline sessions. The remaining 4 participants acquired mastery level passive compliance following fading intervals within the DRO intervention. Participants' passive compliance generalized across 2 novel settings. This study replicates previous studies and extends empirical support for the use of DRO without escape extinction interventions for increasing passive compliance with medical devices in children with ASD.
