The Relationship

Interventions aimed at increasing communicative response variability hold particular importance for individuals with autism spectrum disorders (ASD). Several procedures have been demonstrated in the applied and translational literature to increase response variability. However, little is known about the relationship between reinforcer magnitude and response variability. In the basic literature, Doughty, Giorno, and Miller evaluated the effects of reinforcer magnitude on behavioral variability by manipulating reinforcer magnitude across alternating relative frequency threshold contingencies, with results suggesting that larger reinforcers induced repetitive responding. The purpose of this study was to translate Doughty et al.’s findings to evaluate the relative effects of different magnitudes of reinforcement on communicative response variability in children with ASD. A Lag 1 schedule of reinforcement was in place during each condition within an alternating treatments design. Magnitudes of reinforcement contingent on variable communicative responding were manipulated across the two conditions. Inconsistent with basic findings, the results showed higher levels of variable communicative responding associated with the larger magnitude of reinforcement. These outcomes may have potential implications for interventions aimed at increasing response variability in individuals with ASD, as well as future research in this area.

Deep Pressure

In the past decade, the number of children diagnosed with an autism spectrum disorder (ASD) has steadily increased. A common characteristic of ASD is the presence of stereotypical behaviors (e.g., hand flapping, echolalia), which some have suggested may be associated with heightened arousal and/or anxiety. The purpose of this study is to compare antecedent interventions that have been used to decrease stereotypical behaviors in three elementary students with ASD by modulating arousal. Using a single-case alternating treatments design across participants, we compared the relative efficacy of antecedent exercise with two forms of deep-pressure therapy (DPT; compression vest and weighted blanket). Results of the current study found mixed effects for the interventions, with DPT providing little reduction of stereotypical behaviors and antecedent exercise (riding a stationary bike) providing improvement in two of three cases. Implications for practitioners and future research are provided.

Children with autism spectrum disorders (ASD) struggle to develop appropriate social skills, which can lead to later social rejection, isolation, and mental health concerns. Educators play an important role in supporting and monitoring social skill development for children with ASD, but the tools used by educators are often tedious, lack suitable sensitivity, provide limited information to plan interventions, and are time-consuming. Therefore, we conducted a study to evaluate the use of a sensor system to measure social proximity between three children with ASD and their peers in an inclusive preschool setting. We compared video-coded data with sensor data using point-by-point agreement to measure the accuracy of the sensor system. Results suggest that the sensor system can adequately measure social proximity between children with ASD and their peers. The next steps for sensor system validation are discussed along with clinical and educational implications, limitations, and future research directions.

The Relationship

Purpose The purpose of this paper is to compare the rates and patterns of comorbid anxiety, depression and ADHD across people with: autism spectrum disorder (ASD) plus intellectual disability (ID), ASD/no ID (AS/HFA) and ID only. Design/methodology/approach Data were obtained using structured file review and two psychometric screening instruments. File reviews used a modified version of the Case Review Protocol from the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities. Screening employed the Reiss Screen for Maladaptive Behaviour and the ASD-Comorbidity-Adults scale. Findings Levels of anxiety, depression and ADHD were high for all three groups, and greater than in general population studies. Between groups, the AS/HFA sample had significantly higher anxiety, while the ASD/ID group had significantly greater ADHD. Groups did not differ on measures of depression or total psychopathology. Levels of ADHD, but not anxiety or depression, increased with severity of ID and ASD symptoms. Research limitations/implications More research is needed on the relationship between ASD and both anxiety and ADHD, particularly the identification of these comorbid conditions and their treatment. Practical implications Rigorous screening for comorbid mental health conditions is required to achieve the best outcomes for adults with ASD. Originality/value The study used a broader community-based sample than previous comorbidity research. Including adults with ID but without ASD enabled a comparison of types and rates of disorder across three distinct but related groups with neurodevelopmental disorders.

The Relationship

Cruchet et al. attempt to tease out the myths and facts surrounding the growing popularity of certain dietary approaches in the management of neurodevelopmental disorders, like attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASDs). The authors identify a particular exclusionary-type approach that seeks to eliminate dietary gluten. Although the relationship between celiac disease (CD) and ADHD/ASD is not well established, a repeated clinical feature noted in CD is the elevated levels of nitric oxide in serum and urine. Elevated oxidative stress has also been observed in neurodevelopmental conditions, and the author of this correspondence has been the first to propose that chronic, environmental exposure to the air pollutant, nitrous oxide may contribute to these oxidative stress profiles through neural cholinergic perturbation. Therefore, the purpose of this correspondence is to highlight this biochemical connection between these conditions so as to identify the clinical populations who may realize the greatest benefit of these dietary approaches, while minimizing any potential risk of nutrient deficiencies.

This chapter emphasizes a selective overview of the newest empirical contributions available in the literature within the last decade (i.e., 2008-2019) regarding the use of assistive technology for the inclusion of children with autism spectrum disorders (ASD) in daily settings. According to the including and excluding criteria, 40 studies were retained and grouped in five main categories, namely (1) communication skills, (2) adaptive and/or social skills, (3) life skills, (4) challenging behaviors, and (5) academic performance. The first aim of the chapter was to outline strengths and weaknesses of the aforementioned studies. The second objective of the chapter was to provide some practical and illustrative examples of assistive technology-based programs aimed at the integration of children with ASD in daily settings. Finally, the third purpose was to discuss the findings pointing out some useful guidelines for future research and practice. Results were fairly positive, although some failure occurred. Clinical, educational, psychological, and rehabilitative implications were critically discussed.
