Lay Abstract: Expert recommendations for toddlers who are likely to develop autism include caregivers being actively involved in the services children receive. However, many services available in the community may not follow these recommendations. Evidence suggests that an intervention named Project ImPACT for Toddlers demonstrates positive parent and child outcomes for families in the community. Project ImPACT for Toddlers was designed specifically for toddlers by a group of parents, clinicians, researchers, and funders. It teaches parents of young children strategies to support their child's development in daily routines. This study reports the perspectives of early intervention providers who learned to use Project ImPACT for Toddlers on whether the intervention was a good fit for their practice and easy to use. The study also examines how many agencies are using Project ImPACT for Toddlers and how many families have received the intervention in the community. The goal of the study is to inform the continued use of Project ImPACT for Toddlers in the community and support offering the intervention in other regions. Participants include 38 community providers who participated in a training study of Project ImPACT for Toddlers and completed a survey and semi-structured interview after approximately 3 months of using Project ImPACT for Toddlers with families. Participants perceived the training model as acceptable and appropriate, and identified the group-based model of training, comprehensive materials, and agency support as strengths of the approach. Survey findings complemented the results from the interviews. Data indicate an increasing number of agencies and families accessing Project ImPACT for Toddlers. Efforts to expand evidence-based intervention in early intervention should continue to build upon the model used for Project ImPACT for Toddlers.

Lay Abstract: Naturalistic developmental behavioral interventions for young children with autism spectrum disorder share key elements. However, the extent of similarity between programs within this class of evidence-based interventions is unknown. There is also currently no tool that can be used to measure the implementation of their common elements. This article presents a multi-stage process which began with defining all intervention elements of naturalistic developmental behavioral interventions. Next, intervention experts identified the common elements of naturalistic developmental behavioral interventions using a survey. An observational rating scheme of those common elements, the eight-item NDBI-Fi , was developed. We evaluated the quality of the NDBI-Fi using videos from completed trials of caregiver-implemented naturalistic developmental behavioral interventions. Results showed that the NDBI-Fi measure has promise; it was sensitive to change, related to other similar measures, and demonstrated adequate agreement between raters. This unique measure has the potential to advance intervention science in autism spectrum disorder by providing a tool to measure the implementation of common elements across naturalistic developmental behavioral intervention models. Given that naturalistic developmental behavioral interventions have numerous shared strategies, this may ease clinicians' uncertainty about choosing the "right" intervention package. It also suggests that there may not be a need for extensive training in more than one naturalistic developmental behavioral intervention. Future research should determine whether these common elements are part of other treatment approaches to better understand the quality of services children and families receive as part of usual care.

This study reports child and family outcomes from a community-based, quasi-experimental pilot trial of Project ImPACT for Toddlers that is a parent-mediated, naturalistic, developmental behavioral intervention for children with or at-risk for autism spectrum disorder developed through a research-community partnership. Community early interventionists delivered either Project ImPACT for Toddlers ( n  = 10) or Usual Care ( n  = 9) to families based on Part C assigned provider. Twenty-five families participated, with children averaging 22.76 months old ( SD  = 5.06). Family and child measures were collected at intake, after 3 months of service, and after a 3-month follow-up. Results indicate significantly greater improvements in positive parent-child interactions for Project ImPACT for Toddlers than usual care families, as well as large, but non-significant, effect sizes for Project ImPACT for Toddlers families in children's social and communication skills.

Cross-informant ratings of are considered gold standard for child behavioral assessment. To date, little work has examined informant ratings of adaptive functioning for youth with autism spectrum disorder (ASD). In a large, diverse sample of youth with ASD, this study evaluated parent-teacher concordance of ratings of adaptive functioning and ASD-specific symptomatology across time. The impact of child clinical characteristics on concordance was also examined. Participants included 246 children, their caregivers and teachers. Parent-teacher concordance was variable but generally consistent across time. Concordance was significantly impacted by autism severity and child cognitive abilities. Findings inform the broader concordance literature and support the need to consider child clinical factors when assessing child functioning in samples of children with ASD.

Naturalistic developmental behavioral interventions include an explicit focus on coaching parents to use therapy techniques in daily routines and are considered best practice for young children with autism. Unfortunately, these approaches are not widely used in community settings, possibly due to the clinical expertise and training required. This article presents the work of the Bond, Regulate, Interact, Develop, Guide, Engage (BRIDGE Collaborative), a multidisciplinary group of service providers (including speech-language pathologists), parents, funding agency representatives, and researchers dedicated to improving the lives of young children with autism spectrum disorder and their families. The group selected and adapted a parent coaching naturalistic developmental behavioral intervention specifically for use with toddlers and their families for community implementation. Lessons learned from the implementation process include the importance of therapist background knowledge, the complexity of working with parents of young children, and needed supports for those working closely with parents, including specific engagement strategies and the incorporation of reflective practice., Competing Interests: Financial: This research was supported in part by grants from the Institute of Education Science (R324A130145) and Autism Speaks (8136).Nonfinancial: All authors are members of the BRIDGE Collaborative.

Low- and middle-income countries often have limited resources, underdeveloped health systems and scarce knowledge of autism spectrum disorder. The objectives of this preliminary study were to develop and adapt intervention materials and to train a native clinician to implement a community-based parent-mediated behavioural intervention in rural Gaibandha, Bangladesh. Intervention materials to support parents' use of behavioural strategies were developed and refined by US behavioural intervention experts and Bangladesh field experts. Study investigators trained a native child psychologist in developmental milestones and behavioural intervention techniques. The native clinician delivered a 1-day group education session attended by 10 families of children aged 7-9 years with autism spectrum disorder, followed by two one-on-one training sessions with each family to train and practice individualized strategies for targeted challenging behaviours. Preliminary qualitative results indicate the importance of materials that are culturally appropriate and at an adequate literacy level. All families expressed strong desires to have learned the behavioural strategies when their child was younger and vocalized their need for further support and tools to help their children. This study is a preliminary step to creating sustainable and low-cost autism spectrum disorder interventions in rural Bangladesh, and possibly for families in regions with similar cultural and socioeconomic status backgrounds.

Many individuals with autism spectrum disorders (ASD) display stimulus overselectivity, wherein a subset of relevant components in a compound stimulus controls responding, which impairs discrimination learning. The original experimental research on stimulus overselectivity in ASD was conducted several decades ago; however, interventions for children with ASD now typically include programming to target conditional discriminations in ways that might minimize the prevalence of stimulus overselectivity. The present study assessed 42 children who had been diagnosed or educationally identified with ASD using a discrimination learning assessment. Of these 42 children, 19% displayed overselective responding, which is a lower percentage than that seen in early research. Possible explanations for this decreased percentage, implications for intervention, and future directions for research are discussed., (© Society for the Experimental Analysis of Behavior.)
