Background: According to several comprehensive systematic and narrative reviews, interventions based on applied behaviour analysis principles, or behaviour analytic interventions, are considered evidence based for children with autism spectrum disorder (ASD). However, no comprehensive review of the literature related to behaviour analytic interventions for children with intellectual disability (ID) currently exists. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines (registration ID: CRD42018099317), the purpose of this study was to conduct a systematic review of the relevant published literature on the use of behaviour analytic interventions to develop skills in young children (0–8 years) with ID (and without ASD). A preliminary search of the literature identified 1209 potential studies published between January 2000 and April 2020. The review process resulted in 48 articles consisting of 49 studies (i.e. one paper contained two studies) that met the inclusion criteria. Most used single‐case research designs. Studies were evaluated on five dimensions of methodological quality based on the Scientific Merit Rating Scale developed by the National Autism Center (NAC). The NAC definitions were also used for the quantity and quality of research evidence required for interventions to be considered established or emerging. Results: There were a number of limitations to the quality of the body of research. Nevertheless, various behaviour analytic interventions met criteria for being established interventions when used for targeting communication, adaptive and pre‐academic skills in young children with ID. Behaviour analytic interventions targeting academic skills met criteria for emerging interventions. Conclusions: Although the current literature is limited, results indicate that behaviour analytic interventions may be effectively used to support skill development in children with ID.

3. Predictors of Picture Exchange Communication System (PECS) outcomes.

- Abstract
Background & Aims: Although the Picture Exchange Communication System (PECS) has been demonstrated to be an effective intervention to teach people diagnosed with autism spectrum disorder a functional communication system, the research indicates variability in PECS outcomes across people and studies. Therefore, the purpose of the current study was to explore child characteristics and treatment variables that may explain the variation in, and potentially predict, PECS outcomes., Method: A total of 22 children and youth diagnosed with autism or a related developmental disorder, all of whom scored substantially below average on standardized measures of cognitive and adaptive abilities, participated in a PECS intervention., Results: Participants who achieved high phases of PECS (≥PECS phase IIIb) differed significantly from those who mastered lower PECS phases (≤PECS phase IIIa) in terms of overall, verbal, and nonverbal mental age, matching abilities, and adaptive behavior level. Stimulus generalization was also associated with significant variation in PECS outcome. PECS outcomes could be predicted with good accuracy using a combination of these child characteristics and treatment variables., Conclusions: The findings from the current study suggest that children with relatively higher cognitive and adaptive skill levels are more likely to achieve higher phases of PECS; further, approaches to generalization training also play a role. Factors such as autism symptom severity and parental ratings of maladaptive behavior were not associated with significant differences in PECS outcomes. However, more research is needed., Implications: Gaining a better understanding of predictors of PECS outcomes is important to inform intervention, provide more accurate outcome expectations for families, and guide PECS teaching procedures. Although participants were more likely to achieve higher phases of PECS if they had a higher mental age, adaptive skill level, and matching skills, the average scores for these measures were well below those expected for same age peers. These results indicate that PECS is appropriate for use with children with clinically significant deficits in cognitive and/or adaptive abilities. Further, results suggest that even children who demonstrate more severe symptoms of autism and exhibit more challenging behavior can achieve higher phases of PECS., Competing Interests: Authors 2, 3 and 4 have no conflicting/competing interests.

- Abstract
Cultural responsiveness is critical to providing high-quality behavior analytic services, particularly when providers and recipients have different cultural backgrounds. The purpose of this study was to systematically replicate and extend (Beaulieu et al. (2019) Behavior Analysis in Practice, 12(3), 557-575) by investigating the diversity among applied behavior analysis (ABA) service providers and service recipients in Ontario, service providers' training and experiences in working with diverse families, and service providers' and recipients' perceptions of behavior analysts' cultural responsiveness in practice. Results from 428 participants suggest that service providers and recipients in Ontario differ in demographic characteristics; service providers report having little training in how to serve diverse families; and although service recipients rate providers' skills relatively positively, there is room for improvement. Results suggest a path forward for behavior analysis that includes education and training in cultural responsiveness as well as encouraging and fostering a bidirectional relationship between behavior analysts and the families they serve., Supplementary Information: The online version contains supplementary material available at 10.1007/s40617-023-00825-w., Competing Interests: Conflict of InterestThe authors have no conflict of interest to declare., (© Association for Behavior Analysis International 2023.

- Abstract
Although early intensive behavioral intervention (EIBI) has been clearly shown to be evidence-based, there is very little information available regarding long-term outcomes, especially from community effectiveness studies. We present data on cognitive, adaptive, and autism severity measures from four time points (pre- and post-EIBI and two follow-up points) for a sample of 21 youth, currently aged 16 years on average (range = 13-20) who received EIBI as young children and who have been out of EIBI for a mean of 10 years (range = 8.5-14). Results show heterogeneous outcomes and a general pattern of stability since the end of EIBI, suggesting gains made in EIBI are maintained.

- Abstract
Introduction: Subjective cognitive decline (SCD) in older adults is a condition with a complex phenomenology and diverse etiologies including (but not limited to) mood, personality, and health concerns, as well as biomarkers of preclinical Alzheimer's disease such as amyloid-β deposition and gray matter volume loss. Approximately 60% of affected persons are estimated to decline to Alzheimer's dementia. Regardless of etiology, persons with SCD may be optimal targets for early intervention., Objective: To ascertain the feasibility and impact of mindfulness training (MT) as an early intervention in persons with SCD., Methods: Using a single-blind, randomized controlled trial design, older adults with (n = 14) and without (n = 22) SCD were randomized to either MT or a control condition of psychoeducation (PE) on cognitive aging. EEG/ERP (specifically, the P3 component), structural MRI, and self-report measures of psychological functioning were obtained within 4 weeks prior to and within 2 weeks following intervention., Results: MT resulted in decreased reaction time intra-individual variability for all participants, with a selective increase in the P3 event-related component for those with SCD. Compared with PE, MT also resulted in an increase in percent volume brain change in structural MRI. Finally, all SCD participants reported a decrease in cognitive complaints and increase in memory self-efficacy following intervention., Discussion: Results suggest that MT is a feasible early intervention in persons with SCD. Longer-term follow-up with larger sample sizes will determine whether MT can slow the rate of decline in persons who may be at risk for Alzheimer's dementia.
