Procedures for determining and then modifying the extinction component of multiple schedules for destructive behavior

As a component of reinforcer schedule thinning following functional communication training, multiple schedules of reinforcement produce desirable rates and patterns of communication responses as an alternative response to destructive behavior. However, reinforcement schedule thinning is a gradual process that can take many sessions to obtain therapeutic goals. The desired outcome is that manding occurs only during signaled intervals of reinforcement with a sufficiently lean terminal schedule of reinforcement availability and low rates of destructive behavior. The purposes of this study were to (a) evaluate an assessment for informing the initial duration of extinction for alternative responding, (b) evaluate the utility of competing stimuli during extinction for alternative responding, and (c) assess a method for fading the availability of competing stimuli. With these procedures, all 4 participants experienced terminal schedules of reinforcement with rapid, robust reductions in destructive behavior soon after baseline. We discuss the implications and directions for future research.

Psychological treatment strategies for challenging behaviours in neurodevelopmental disorders: what lies beyond a purely behavioural approach?

PURPOSE OF REVIEW

Challenging behaviour shown by individuals with neurodevelopmental disorders (NDDs) has a major negative impact. There is robust evidence for the efficacy of treatments based on applied behaviour analysis. However, such approaches are limited in important ways - providing only part of the whole solution. We reviewed the literature to provide an overview of recent progress in psychological treatments for challenging behaviour and how these advance the field beyond a purely behavioural approach.

RECENT FINDING

We identified 1029 articles via a systematic search and screened for those implementing a psychological intervention with individuals with NDD (or caregivers) and measuring the potential impact on challenging behaviour. Of the 69 included studies published since 2018, more than 50% implemented a purely behavioural intervention. Other studies could generally be categorized as implementing parent training, meditation, skill training or technology-assisted interventions.

SUMMARY

Greater consideration of the interplay between behavioural and nonbehavioural intervention components; systematic approaches to personalization when going beyond the behavioural model; mental health and broad social communication needs; and models that include cognitive and emotional pathways to challenging behaviour; is needed to advance the field. Furthermore, technology should not be overlooked as an important potential facilitator of intervention efforts.

Introduction to the Special Issue: Interventions to Reduce Challenging Behavior Among Individuals With Autism Spectrum Disorder

The prevalence of autism spectrum disorder (ASD) is on the rise. In addition to the social communication skill deficits and restrictive repetitive behaviors and interests, many individuals with ASD engage in challenging behavior. Challenging behavior is associated with a multitude of negative outcomes. Challenging behavior may cause harm to the individual with ASD as well as limit opportunities for educational, vocational, and social participation and development. In addition, caregivers experience high stress and low quality of mental health. As a result, challenging behavior warrants intervention that is specifically tailored to the unique characteristics of individuals with ASD. The purpose of this Special Issue is to showcase recent research in the treatment of challenging behavior for individuals with ASD. This two-part Special Issue contains 12 studies that range from systematic and quality reviews of the intervention literature, to innovative treatment approaches, to studies that develop and evaluate treatments for restrictive and repetitive behaviors and interests.
