J Autism Dev Disord 2024; 54:2769-2776.

Abstract
We explored associations among the core behavioural features and developmental/cognitive abilities of 155 autistic children, assessed between ages 13-67 months and again around 1-year later to understand predictive directionality. Bidirectional, cross-domain association was apparent, albeit with stronger direction of effect from earlier cognition to later autism features (than vice versa). Exploratory sub-domain analysis showed that early non-verbal developmental/cognitive abilities (only) predicted subsequent social- and restricted/repetitive autism features, whereas early social features (only) predicted both subsequent verbal and non-verbal abilities. Although observational study design precludes causal inference, these data support contemporary notions of the developmental interconnectedness of core autism presentation and associated abilities-that behavioural autism features may influence cognitive development, but are likely also influenced by an individuals' cognitive capacity.

Abstract
The effectiveness of a school based Early Intensive Behavioural Intervention (EIBI) program was assessed over a two-year period for a cohort of 16 pre-school children with autism spectrum disorder (ASD) and their families. Children with a mean age of 40 months, were assessed prior to intervention, after 1 year of intervention, and again after 2 years. Significant improvements were observed on measures of adaptive behaviour, communication ability and challenging behaviour. Parents of children attending the program also reported increased familial quality of life, specifically improved emotional and physical well-being and increased parenting capacity over the duration of the program. The current study suggests that EIBI for young children with ASD can be effective in facilitating improvements in communication ability, reducing challenging behaviours and improving quality of life for families. Children's pre-intervention adaptive skills appeared to be the strongest predictor of post intervention gains as initial level of adaptive ability was positively related to improved post-intervention outcomes.

Abstract
We conducted an overview of reviews to determine the effects of naturalistic developmental behavioral interventions (NDBIs; Schreibman et al. (2015) J Autism Dev Disorders 45:2411-2428) on children with autism spectrum disorder under 8 years old. We conducted an electronic database search of Academic Search Premier, CINHAL, ERIC, Medline, and APA PsycINFO in October 2022 and August 2023 and utilized snowball methods to locate relevant reviews of NDBI. We included reviews meeting the following inclusion criteria: (1) review included a meta-analytic synthesis for at least one child outcome; (2) primary studies examined a NDBI; (3) primary studies included children with ASD with a mean pre-treatment age under eight years; (4) primary studies were conducted using a two-group comparison design; and (5) review was published in English. We extracted data on characteristics of the review, participant characteristics from the primary studies, intervention characteristics, and assessed the risk of bias of the included reviews. We conducted a narrative synthesis across outcomes reported in the included reviews. We included five reviews from six reports in this overview. Two reviews included studies that examined the Early Start Denver Model, two reviews included studies that examined the Pivotal Response Treatment, and one review included studies examining NDBIs collectively. We found positive effects of NDBIs on child's communication/language, cognition, and adaptive behavior. We found mixed effects for NDBIs on autism symptomatology and restricted and repetitive behaviors. Examination of moderator analyses reported in the included reviews suggested variables influencing the effects of NDBIs included proximity of outcome to intervention, boundedness of outcome to intervention, and study location. As shown in this overview, positive effects of NDBI for young children with ASD are supported by meta-analytic evidence. While the overall findings for NDBI across reviews are positive, the findings on specific outcomes and influential variables moderating the effects of NDBI are inconsistent. Additional evidence from randomized controlled trials and future meta-analyses are needed to strengthen our knowledge of the effects of NDBI for young children with ASD.Protocol Registration: PROSPERO CRD42022353045.

Abstract
The objective of this research was to assess the efficacy of behavioral therapy interventions in the treatment of autism spectrum disorders (ASD). The study utilized the PubMed and Embase databases to locate randomized controlled trials, quasi-experimental treatment studies, and randomized clinical trial comparisons. The experimental group received treatment based on an applied behavioral approach, such as PECS, DTT, PRT, TEACCH, ESDM, and EIBI. After examining seventeen studies, the researchers found that each type of behavioral intervention had a positive impact. Naturalistic protocols that employed PRT and PECS improved ASD symptoms in general, despite their targeting of particular cognitive domains such as language. ESDM enhanced receptive language, particularly in preschool-aged children. Structured and integrated interventions, like EIBI and TEACCH, improved overall adaptive functioning. Combining DTT with a TEACCH program produced greater benefits in linguistic, affective-social, and personal autonomy domains. However, there is a scarcity of high-quality research available on behavioral interventions for ASD. Further comparative studies are necessary to identify cost-efficient interventions. For example, PRT and PECS significantly improved social communication skills in only 15-40 hours over six months. The authors emphasized the need for continued research and the application of evidence-based interventions in specialized settings.

Abstract
The COVID-19 pandemic caused a temporary lockdown period in Italy, during which the delivery of in-person treatment for children with autism spectrum disorder (ASD) in public health services was discontinued. This occurrence represented a crucial challenge for both families and professionals. We assessed the short-term outcomes of a sample of 18 children who received an early intervention with the Early Start Denver Model (ESDM), delivered at low intensity over one year in the pre-pandemic period, after six months of interruption of in-presence treatment due to lockdown restrictions. Children who received the ESDM treatment maintained their gains in sociocommunicative skills and did not exhibit any developmental regression. Additionally, there was evidence of a decrease in the restrictive and repetitive behavior (RRB) domain. The parents, who were already familiar with the principles of the ESDM, only received telehealth support from therapists that aimed to sustain the gains already achieved. We believe that it is always helpful to support parents in their daily lives by implementing interactional and play skills with their children to integrate and consolidate the results obtained in the individual interventions conducted by experienced therapists.

Importance of Early Intervention in Reducing Autistic Symptoms and Speech-Language Deficits in Children with Autism Spectrum Disorder. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10010122. [PMID: 36670672 PMCID: PMC9857540 DOI: 10.3390/children10010122] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 12/05/2022] [Accepted: 12/28/2022] [Indexed: 01/11/2023]
Abstract
The intervention focused on starting treatment at an early age to develop the child’s full potential, which is known as early intervention. Given that autistic symptoms and language deficits occur at an early age and affect other areas of development in children with autistic spectrum disorder, we wanted to examine if early intervention is more effective in the reduction in autistic symptoms and language deficits in children aged 36−47 months old when compared to children 48−60 months old. The sample consisted of 29 children diagnosed with ASD who were admitted for integrative therapy. All participants were divided into two groups based on age: G1: 36−47 months old children, and G2: 48−60 months old children. To estimate the presence of autistic symptoms, we used the GARS-3, and for the assessment of speech−language abilities, we used the subscale Estimated Speech and Language Development (ESLD). Our results regarding the effect of the group on the difference in the scores at two time points showed that there was a statistically significant effect of the group on the reduction in autistic symptoms (p < 0.05) but no effect of the group on the differences in speech−language abilities between the two time points (p > 0.05). Our study highlights the importance of emphasizing the exact age when using the terms “early intervention” and “early development” in future studies and practice because it is necessary to determine and establish guidelines about which particular ages are crucial for starting treatment in certain developmental aspects.

Abstract
Synchronous positive affect (SPA) is a key element of parent-child interaction quality which is related to favorable developmental outcomes. Children with autism spectrum disorder (ASD) and their parents tend to show less SPA compared to other populations. The current study explored changes in SPA made by parents and their children with ASD following the Preschool-Based Early Start Denver Model (PB-ESDM) intervention. Thirty children receiving PB-ESDM and 23 receiving treatment-as-usual (TAU) were assessed pre- and post- intervention using microanalysis of video-recorded parent-child interactions, in which SPA was quantified. Results showed a significant increase in SPA among children receiving PB-ESDM who had lower pre-treatment adaptive functioning. These findings suggest that SPA may serve as a sensitive treatment outcome measure for children with poorer adaptive functioning, who often struggle to show significant changes on standardized measures. The study's modest sample and non-randomized design are noted as limitations.

Abstract
A randomized feasibility trial of a parent coaching (PC) intervention was conducted across 16 community agencies in a Canadian province. Parents of toddlers with suspected autism were assigned to either a PC group (n = 24) or an enhanced community treatment (ECT) group (n = 25). PC participants received 24 weeks of coaching support from community service providers trained in the project. Children in both groups also received available community services and supplementary materials. PC children made significantly greater gains in word understanding and PC parents had significantly higher quality of life, satisfaction, and self-efficacy scores. Results are discussed in terms of the challenges of conducting feasibility studies in community settings and the lessons learned in the project.

Abstract
Naturalistic developmental behavioral interventions (NDBI) are an evidence-based class of early interventions for improving language and social communication skills in autistic children. However, relatively little is known about how individual elements of NDBI support child development. This commentary focuses on one common element across NDBI models: the simplification of adult language input. Advances in developmental science focusing on the length and complexity of adult spoken utterances suggests that natural, grammatical utterances facilitate comprehension and expressive language development in autistic and nonautistic children. Yet, NDBI tend to recommend shorter and simpler adult utterances. We close by describing directions for future research which would inform recommendations around adult language input in NDBI to optimally support child language and communication development.

Efficacy and moderating factors of the Early Start Denver Model in Chinese toddlers with autism spectrum disorder: a longitudinal study. World J Pediatr 2022:10.1007/s12519-022-00555-z.

Abstract
BACKGROUND Several studies have shown the effectiveness of the Early Start Denver Model (ESDM), but few studies have explored the long-term efficacy of ESDM. This study aimed to explore the efficacy and moderating factors of ESDM in Chinese toddlers with autism spectrum disorder (ASD) in a longitudinal way. METHODS A total of 60 toddlers with ASD were recruited and randomly divided into two groups: ESDM group all received 24 weeks intervention; Control group were waiting for intervention. Baseline assessment (T0) was conducted before intervention, including Gesell Developmental Scale (GDS) and Psycho-educational Profile-3rd Edition (PEP-3). All toddlers with ASD were examined in the first assessment (T1) at 6 months and in the second assessment (T2) at 12 months. RESULTS In T1 assessment, the increments in speech and personal communication development quotient in GDS were significantly larger in the ESDM group than in the control group (P = 0.010, 0.047). In T2 assessment, the ESDM group had higher elevation in cognitive verbal/preverbal (CVP), social reciprocity and characteristic verbal behaviors assessed by PEP-3 (P = 0.021, 0.046, 0.014). In addition, the severity of stereotyped behavior was negatively associated with improvement in CVP. Family income was positively associated with improvement in speech and CVP (all P < 0.05). CONCLUSIONS ESDM can effectively improve speech and communication in toddlers with ASD after 24-week intervention. More importantly, ESDM can promote cognition and social interaction and can reduce stereotyped verbal behavior in toddlers with ASD in longitudinal observation. The severity of stereotyped behavior and family ecological factors may be considered as affecting the efficacy of ESDM.

Abstract
Evaluation of the rehabilitation efficacy may be an essential indicator of its further implementation and planning. The research aim is to examine whether the estimation of EEG correlates of auditory-verbal processing in a child with overlapping autism spectrum disorder (ASD) and specific language impairment (SLI) symptoms may be a predictor of the treatment efficacy in conditions when behavioral tests do not show improvement during the time course. The prospective case report reports follow-up results in a child aged 36 to 66 months. During continuous integrative therapy, autism risk index, cognitive, speech-language, sensory, and EEG correlates of auditory-verbal information processing are recorded in six test periods, and their mutual interrelation was analyzed. The obtained results show a high statistically significant correlation of all observed functions with EEG correlates related to the difference between the average mean values of theta rhythm in the left (F1, F3, F7) and right (F2, F4, F8) frontal region. The temporal dynamics of the examined processes point to the consistency of the evaluated functions increasing with time flow. These findings indicate that EEG correlates of auditory-verbal processing may be used to diagnose treatment efficacy in children with overlapping ASD and SLI.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19052555. [PMID: 35270253 PMCID: PMC8909550 DOI: 10.3390/ijerph19052555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 02/01/2022] [Accepted: 02/10/2022] [Indexed: 11/17/2022]
Abstract
We aimed to address a policy-relevant research area with high priority, namely disseminating early intervention for children on the autism spectrum into mainstream community settings. The study cohort comprised 47 children with a diagnosis of Autism Spectrum Disorder (ASD) receiving the Early Start Denver Model (ESDM) intervention: 23 children attending an Autism Specific Early Learning and Care Centre (ASELCC) and 24 children attending a mainstream preschool setting. Group comparisons revealed that the overall response to intervention was in the majority of cases not significantly different between settings. One difference was found in that children in the mainstream preschool setting showed a significant reduction in externalising behaviours compared to the children attending the autism-specific preschool. Intervention duration was found to influence outcomes with a one-month increase in duration found to improve expressive language skills. While the results need to be interpreted with caution due to the small sample size, these findings suggest that early intervention can be successfully delivered in both autism-specific and mainstream settings. However, those families needing additional parent support may be better served by a specialised service.

Abstract
The school-age outcomes of autistic children who received early interventions (EI) remains limited. Adaptive functioning, social, peer play skills, problem behaviours, and attitudes towards school of 31 autistic children who received community-based group early start Denver model (G-ESDM) were compared to 28 age matched autistic children who received other community interventions. Similar adaptive behaviours, social skills, problem behaviours and attitudes towards school were found. Play disruption was the only dimension of play to differ; children that received community interventions demonstrated higher levels of play disruption compared to the G-ESDM group. Children had pervasive challenges in adaptive behaviour, social and play behaviour at school, irrespective of EI type. Thus, ongoing provisions are needed to support development into the school years.

Abstract
We conducted a systematic review to identify randomized controlled trials (RCTs) and single case research design (SCRD) studies of children with autism spectrum disorder that evaluate the effectiveness of responsivity intervention techniques for improving prelinguistic and/or language outcomes. Mean effect sizes were moderate and large for RCTs (33 studies; g = 0.36, 95% CI [0.21, 0.51]) and SCRD (34 studies; between-case standardized mean difference = 1.20, 95% CI [0.87, 1.54]) studies, respectively. Visual analysis (37 studies) revealed strong evidence of a functional relation for 45% of the opportunities and no evidence for 53%. Analyses of moderator effects and study quality are presented. Findings provide support for responsivity intervention strategies with more robust support for context-bound outcomes than more generalized outcomes.

Abstract
The Early Start Denver Model (ESDM) is an evidence-based early intervention model for young children with autism spectrum disorder (ASD). It is crucial to investigate the feasibility of the ESDM in community settings in contexts that are culturally different from American universities in which the model was originally developed. The aim was to further evaluate the effectiveness of the ESDM delivered within the Italian community setting at low intensity. We compared a group aged 19 to 43 months receiving the ESDM for 2 h per week over the course of 1 year with a concurrent, comparable, non-randomized control group receiving treatment as usual (TAU). Children were evaluated at baseline (T0) and after 6 months (T1) and 12 months (T2) of intervention. Feasibility was evaluated by parent and therapist questionnaires, retention rate, and therapist treatment fidelity. Both groups made similar gains in cognition and language abilities. The ESDM group made larger improvement in domains measured by the ESDM Curriculum Checklist, including communication, social skills, and maladaptive behaviors. Feasibility seemed well supported by retentions, therapists and parent satisfaction, and treatment fidelity. Our study further supports the feasibility of the ESDM implemented within the Italian public health system and suggests a better response in the ESDM-treated group than in the control group.

Abstract
LAY ABSTRACT Early intensive applied behaviour analysis-based interventions are designed to support young autistic children's learning and development. Unfortunately, the available evidence about the effectiveness of these interventions remains unclear. Several reviews have focused on the published findings rather than contacting the authors to collect and analyse data about the individual participants in the original studies. Also, most of the studies were carried out by groups involved in delivering the interventions leading to the potential bias in interpreting the results. Our research team (supported by an international advisory group) carried out an independent individual patient data review by collecting the original participant data from the authors of the studies, to examine the effectiveness of these interventions. The results suggested that early intensive applied behaviour analysis-based interventions might lead to some changes in children's cognitive ability (intelligence quotient) and everyday life skills after 2 years, compared with standard treatments. However, all the studies had problems with the way they were designed. Also, few of the studies looked at outcomes that have been described as most important to autistic people or followed children beyond 2 years. We think that further systematic reviews of the existing evidence are unlikely to add to the findings of our review. Furthermore, we recommend that future research should investigate which types of supports and interventions are most effective for children and families, prioritising outcomes measures that are meaningful for the autism community and include, wherever possible, longer-term follow-up.

Abstract
Globally, there are more bilingual speakers than monolingual speakers; however, scant research evidence exists regarding social communication development and outcomes for bilingual children with autism spectrum disorder (ASD). A stronger evidence base will facilitate health professionals and educators providing accurate recommendations regarding language use. This study employed a longitudinal cohort design to compare social and communication skills, at baseline and over 12 months, for 60 monolingual and 60 bilingual children with ASD receiving community based early intervention. We found few differences at intake, and no difference in the magnitude of change over 12 months for this cohort. Findings support the notion that there is no basis on which to discourage home language use with bilingual children with ASD.

Abstract
The Early Start Denver Model (ESDM) is an evidence-based early intervention approach for young children with autism spectrum disorder. Although the ESDM is described by its authors as being rooted in applied behavior analysis (ABA), some states, agencies, and scholars consider the ESDM to qualify as ABA practice, whereas others do not. The purpose of this article is to examine the status of the ESDM in relation to the 7 dimensions established by Baer, Wolf, and Risley ("Some Current Dimensions of Applied Behavior Analysis," Journal of Applied Behavior Analysis, 1(1): 91-97, 1968) to define applied behavior-analytic research and intervention, as well as to discuss implications for the field.

Abstract
Autism Spectrum Disorder (ASD) is a complex highly heritable disorder, in which multiple environmental factors interact with the genes to increase its risk and lead to variable clinical presentations and outcomes. Furthermore, the inherent fundamental deficits of ASD in social attention and interaction critically diverge children from the typical pathways of learning, "creating" what we perceive as autism syndrome during the first three years of life. Later in life, training and education, the presence and management of comorbidities, as well as social and vocational support throughout the lifespan, will define the quality of life and the adaptation of an individual with ASD. Given the overall burden of ASD, prevention strategies seem like a cost-effective endeavour that we have to explore. In this paper, we take a life course approach to prevention. We will review the possibilities of the management of risk factors from preconception until the perinatal period, that of early intervention in the first three years of life and that of effective training and support from childhood until adulthood.

Abstract
Objectives: To examine and analyse the intervention effects of the Early Start Denver Model (ESDM) on children with autism spectrum disorder (ASD). Methods: This meta-analysis evaluated the effect sizes in four major domains of measurement (autism symptoms, language, cognition, and social communication). A total of 624 participants with ASD were included in 11 high-quality randomized controlled trial studies. Results: The results indicated that the ESDM intervention resulted in significant improvement with moderate effect sizes in the cognition (g = 0.28), autism symptoms (g = 0.27), and language (g = 0.29) domains. The effect sizes of autism symptoms and language were moderated by country (Western versus Asian countries). However, there were no significant effects observed for the social communication domain. Conclusion: The ESDM intervention significantly improved autism symptoms, language, and cognition. The effect sizes of autism symptoms and language were larger in Asian countries than in Western countries.

Abstract
BACKGROUND AND AIMS Play is used by practitioners from across disciplinary backgrounds as a natural and enjoyable context for providing intervention and support in early childhood. In the case of autism interventions, many therapies are based on the association between social play and the development of social skills, language development, and communication skills, as these are often particular areas of challenge for autistic children. However, play is a wide-ranging concept and the extant literature on play-based interventions is large and heterogeneous. This means it is challenging for practitioners and families to navigate the evidence base and make choices about differing intervention strategies. This review aims to provide a comprehensive map of the research on this topic and to develop a conceptual framework to inform clinical decision-making. METHODS An initial stakeholder consultation confirmed the relevance of the topic to practitioners and autistic people. A scoping review methodology (preregistered) was used to identify relevant literature. We systematically searched seven databases to find peer-reviewed primary intervention studies of play-based approaches targeting language, social and communication outcomes for autistic children aged 2-8 years. We then summarised the literature using narrative synthesis and Evidence Gap Maps (EGMs). The literature was summarised according to a range of characteristics, including study design, population characteristics, agent of intervention and outcomes measured, among others. These summaries were then used to develop a framework for some key considerations for practitioners appraising play-based approaches. RESULTS 388 studies met inclusion criteria. Approximately 21% of studies were RCTs, and over 50% had ≤10 participants. Over 45% of studies reported multiple relevant outcomes, with social play skills being the most common single intervention target. Girls and minority background groups are under-represented. A range of intervention types were identified, and some high-level categorisations are proposed.Main contribution: On the basis of the evidence synthesis we suggest important dimensions for appraisal of play-based interventions, including the role of play within an intervention (as a context, a key developmental mechanism, or a component of a larger approach), the underpinning philosophy (e.g. behaviourist or developmental), and the role of the practitioner (providing parent feedback, 1:1 intervention, group facilitation). CONCLUSIONS The wide range of approaches uncovered by this review is a testament to the wonderful diversity inherent to both play and autism. However, research could usefully focus on consolidating the evidence base for existing approaches, rather than aiming for further diversification. Implications: The conceptual framework proposed in this review can help practitioners appraise the literature and aid their advice to families when making shared intervention decisions.

Abstract
The aim of this article was to analyze the evidence regarding the effectiveness of intervention programs for children with autism based on the participation of their parents. To obtain the data, a systematic search was carried out in four databases (PsycARTICLES (ProQuest), ERIC (ProQuest), PubMed (ProQuest), and Scopus). The retrieved documents were refined under the inclusion/exclusion criteria, and a total of 51 empirical studies were selected. These studies were first classified according to the function of the intervention objective and, later, by the methodology applied (19 studies were based on comprehensive interventions, 11 focused on the nuclear symptoms of autism spectrum disorder (ASD), 12 focused on the promotion of positive parenting, and nine interactions focused on child play). Once all of the documents had been analyzed, the evidence indicated scientific efficacy in most studies, mainly in those based on child development and the application of behavioral analysis principles. Moreover, the positive influence of parent participation in such programs was demonstrated.

Abstract
BACKGROUND The 2030 Agenda for Sustainable Development adapted by the United Nations envisions inclusive and equitable quality education. While there is a growing body of research on interventions designed to help children on the autism spectrum adapt to the school environment, accommodations to children needs have been given less attention. OBJECTIVE To synthesize the literature on accommodations in the learning environment for children on the autism spectrum (ages 5-19 years) in mainstream school, with a specific focus on the effects on functioning, educational outcomes and well-being. METHODS A systematic search was conducted. The study selection and data extraction were performed by two independent reviewers. Eligible studies were assessed according to the What Works Clearinghouse (WWC) standards. RESULTS The search yielded 6102 citations. Only 37 eligible studies were identified, of which 14 met the WWC standards. This inconclusive and heterogeneous body of research tentatively suggest that accommodations in the pedagogical and psychosocial leaning environment can improve performance and function in school. CONCLUSION AND SIGNIFICANCE Accommodations in the learning environment is a promising but understudied approach. Creative research and innovation will be needed to support policy makers and school personnel in their quest to ensure inclusive and equitable education.

Abstract
Early intensive intervention has been shown to significantly affect the development of children with autism spectrum disorder. However, the costly implementation of such interventions limits their wide dissemination in the community. This study examined an integration of the Early Start Denver Model into community preschool programs for children with autism spectrum disorder in Israel. Four community preschools implemented the preschool-based Early Start Denver Model and four implemented a multidisciplinary developmental intervention which is widely applied in Israeli community autism spectrum disorder preschools. Fifty-one children (aged 33–57 months) participated in the study. Twenty-six attended the preschool-based Early Start Denver Model preschools and twenty-five attended the multidisciplinary developmental intervention settings. Groups were comparable on age, developmental functioning, and socio-economic status. Compared to the multidisciplinary developmental intervention group, children in the preschool-based Early Start Denver Model treatment made greater gains on blinded measures of overall cognitive development, receptive and expressive language skills, as well as on parent- and teacher-reported adaptive communication and socialization abilities. In the preschool-based Early Start Denver Model group, children with lower symptom severity, higher adaptive functioning, and receptive language abilities at pre-treatment showed greater improvement. This study documents the successful integration of an Early Start Denver Model intervention into pre-existing community preschools, underlining the importance of disseminating evidence-based early intervention in community settings.

Abstract
BACKGROUND Early intensive applied behaviour analysis-based interventions are intensive interventions for autistic children that are often delivered on a one-to-one basis for 20-50 hours per week. OBJECTIVES To evaluate the clinical effectiveness and cost-effectiveness of early intensive applied behaviour analysis-based interventions for autistic children, based on current evidence. METHODS A systematic review and individual participant data meta-analysis were conducted to evaluate the clinical effectiveness of an early intensive applied behaviour analysis-based intervention for autistic children. An economic analysis included a review of existing analyses and the development of a new model. RESULTS Twenty studies were included in the clinical review. Individual participant data were retrieved from 15 of these studies. Results favoured the interventions when assessing adaptive behaviour after 2 years compared with treatment as usual/eclectic interventions (mean difference 7.00, 95% confidence interval 1.95 to 12.06). In analyses of cognitive ability (intelligence quotient), results favoured the interventions by approximately 10 points after 1 year (mean difference 9.16, 95% confidence interval 4.38 to 13.93) and 2 years (mean difference 14.13, 95% confidence interval 9.16 to 19.10). Evidence for other outcomes was limited and meta-analyses were generally inconclusive. There was no evidence that the effect of the interventions varied with characteristics of the children, but data were limited. Adopting a £30,000 per quality-adjusted life-year threshold, the results of the cost-effectiveness analysis indicate that early intensive applied behaviour analysis-based interventions would need to generate larger benefits or cost savings to be cost-effective. Adopting a public sector perspective and making pessimistic assumptions about long-term effects, the incremental cost-effectiveness ratio for early intensive applied behaviour analysis-based therapy compared with treatment as usual is £189,122 per quality-adjusted life-year. When optimistic assumptions are made, the incremental cost-effectiveness ratio is £46,768 per quality-adjusted life-year. Scenario analyses indicated that these interventions can potentially be cost-effective if long-term improvements persist into adulthood, or if they have significant impact on educational placement. Care should be taken when interpreting these scenarios owing to the limited data. LIMITATIONS All included studies were at risk of bias, there was substantial heterogeneity and effects varied considerably across studies. The effect of intervention on autism symptom severity, language development and school placement remains uncertain because of the limited data. The long-term effects are unclear owing to a lack of follow-up data. CONCLUSIONS This review found limited evidence that early intensive applied behaviour analysis-based interventions may improve cognitive ability and adaptive behaviour, but the long-term impact of the interventions remains unknown. The economic analysis is constrained by the limited effectiveness evidence, but suggests that these interventions are unlikely to be cost-effective unless clear long-term benefits, or a substantial change in which schools children attend, can be identified. FUTURE WORK Further studies into the effectiveness of early intensive applied behaviour analysis-based interventions may be warranted if they include well-defined, alternative interventions as comparators and collect relevant outcomes. Consideration should be given to future studies that not only address whether or not early intensive applied behaviour analysis-based interventions are clinically effective, but also aim to identify which components of early intensive applied behaviour analysis-based interventions might drive effectiveness.

The Effects of the Early Start Denver Model for Children with Autism Spectrum Disorder: A Meta-Analysis. Brain Sci 2020; 10:brainsci10060368. [PMID: 32545615 PMCID: PMC7349854 DOI: 10.3390/brainsci10060368] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 06/02/2020] [Accepted: 06/09/2020] [Indexed: 01/06/2023] Open
Abstract
This meta-analysis examined the effects of the Early Start Denver Model (ESDM) for young children with autism on developmental outcome measures. The 12 included studies reported results from 640 children with autism across 44 unique effect sizes. The aggregated effect size, calculated using a robust variance estimation meta-analysis, was 0.357 (p = 0.024), which is a moderate effect size with a statistically significant overall weighted averaged that favored participants who received the ESDM compared to children in control groups, with moderate heterogeneity across studies. This result was largely driven by improvements in cognition (g = 0.412) and language (g = 0.408). There were no significant effects observed for measures of autism symptomology, adaptive behavior, social communication, or restrictive and repetitive behaviors.

Abstract
Purpose This study synthesized effects of interventions on language outcomes of young children (ages 0-8 years) with autism and evaluated the extent to which summary effects varied by intervention, participant, and outcome characteristics. Method A subset of effect sizes gathered for a larger meta-analysis (the Autism Intervention Meta-analysis or Project AIM) examining the effects of interventions for young children with autism, which were specific to language outcomes, was analyzed. Robust variance estimation and metaregression were used to calculate summary and moderated effects while controlling for intercorrelation among outcomes within studies. Results A total of 221 outcomes were gathered from 60 studies. The summary effect of intervention on language outcomes was small but significant. Summary effects were larger for expressive and composite language outcomes compared to receptive language outcomes. Interventions implemented by clinicians, or by clinicians and caregivers together, had summary effects that were significantly larger than interventions implemented by caregivers alone. Participants' pretreatment language age equivalent scores positively and significantly moderated intervention effects, such that effects were significantly larger on average when samples of children had higher pretreatment language levels. Effects were not moderated by cumulative intervention intensity, intervention type, autism symptomatology, chronological age, or the proximity or boundedness of outcomes. Study quality concerns were apparent for a majority of included outcomes. Conclusions We found evidence that intervention can facilitate improvements in language outcomes for young children with autism. Effects were largest for expressive and composite language outcomes, for children with initially higher language abilities, and for interventions implemented by clinicians or by caregivers and clinicians combined. However, quality concerns of included studies and borderline significance of some results temper our conclusions regarding intervention effectiveness and corresponding moderators.

Abstract
Mounting evidence supports several naturalistic developmental behavioral interventions (NDBI) for toddlers and preschoolers within inclusive childcare centers and preschools. However, these interventions pose many barriers to community implementation. As part of a larger project to create an adapted NDBI for early educators in childcare centers, we surveyed 101 early interventionists who had worked with a toddler with autism within the last 12 months. Early interventionists rated 22-of-31 NDBI strategies to be significantly more effective for All Toddlers versus Toddlers with Autism. However, when comparing the top 10 rated strategies between groups, there was a large degree of overlap. Moreover, many of these highly rated NDBI strategies are consistent with best practice accreditation and early education standards within the United States.

Abstract
This literature review evaluated early behavioral intervention studies of Autism Spectrum disorder (ASD) based on their participant exclusion criteria. The studies included were found through searching PsycINFO and PubMed databases, and discussed behavioral interventions for children up to 5 years of age with ASD and utilized a group research design. Studies reviewed were categorized into three groups: Restrictive exclusion criteria, loosely defined exclusion criteria, and exclusion criteria not defined. Results indicated that studies that used restrictive exclusion criteria demonstrated greater differences in terms of outcomes between experimental and control groups in comparison to studies that used loosely defined exclusion criteria and/or did not define any exclusion criteria. We discussed implications for the generalizability of the studies' outcomes in relationship to exclusion criteria.

Abstract
Several studies have shown the efficacy and effectiveness of the Early Start Denver Model, both in university and in community-based settings. However, a limited number of studies have investigated predictors of outcomes. In this study, we examined outcomes in 32 children diagnosed with autism spectrum disorder after 1 year of community-based Early Start Denver Model intervention, with the aim to identify predictors of treatment objectives acquisition, as measured by the Early Start Denver Model Curriculum Checklist. At a group level, the participants demonstrated improvement in their communication as well as adaptive functioning skills, while they showed a decrease in symptom severity. The large heterogeneity in outcomes identified was related to the pre-treatment non-verbal abilities, symptom severity, action and gesture repertoire, and lexical comprehension. We discussed our results in terms of implications for developing "personalized" interventions for children with autism spectrum disorder.

Abstract
Relatively few studies have examined gender differences in infants and toddlers, and most focus on clinically referred samples or high-risk infant cohorts. The current study aimed to examine gender differences in early autism manifestations and cognitive development in a community-ascertained sample. In total, 46 males and 21 females with ASD were seen at approximately 24 and 48 months of age. No significant gender differences were observed on overall cognitive ability, verbal skills, non-verbal skills, overall autism severity, or restricted repetitive behaviours. However, females were found to exhibit more social communication impairments than males. These findings may indicate that female toddlers with less severe or different, social communication impairments may be more likely to be missed during routine surveillance during toddlerhood.

Abstract
OBJECTIVE To investigate the feasibility and effectiveness of early autism intervention with the Early Start Denver Model (ESDM) implemented with low intensity in a community service in Europe. METHODS Subjects were boys (n = 13, ages 34-54 months, mean age 43.3 months) consecutively diagnosed with autism spectrum disorder in a regional autism center in Austria. The subjects either received the ESDM intervention for 4.6 hours weekly over 12 months (n = 7) or intervention as usual (n = 6). Feasibility of the ESDM intervention was evaluated by parent and teacher questionnaires, ESDM fidelity measures, and therapists' feedback. Developmental status was assessed through standardized instruments (Mullen Scales of Early Learning [MSEL], Vineland Adaptive Behavior Scales Second Edition, Communicative Development Inventory, Pervasive Developmental Disorder Behavior Inventory [PDDBI], Parenting Sense of Competence Scale) at baseline and after intervention. RESULTS The ESDM intervention was delivered with high fidelity (>80%) by a newly trained multiprofessional team. Acceptability by parents was rated as high. The ESDM was considered to be compatible with both family and preschool routines without any major adaptations. The ESDM group showed a trend toward improved receptive language (MSEL receptive language; p = 0.09, effect size [ES] = 0.72) and reduction in parent-reported core autism symptoms (PDDBI Autism Composite Score; p = 0.04; ES = 0.95). No such improvement was noted in the control group. CONCLUSION Low-intensity implementation of the ESDM in a non-English-speaking community service context is feasible. Although outcomes from this small feasibility study should be interpreted with caution, our findings suggest a more favorable response to the ESDM intervention group compared with the control group.

Abstract
Purpose Speech-language pathologists (SLPs) often simplify their language input when talking to young children with language delays, but there is some controversy regarding whether simplified input should be telegraphic (e.g., Ball under, Doggie go, More toy) or grammatical (e.g., The ball went under; Go, Doggie! More toys). The purpose of this study was to evaluate SLPs' practices and perspectives on using telegraphic input when working with children with language delays at the prelinguistic, one-word, or two-word stages of spoken language development. Method Practicing SLPs were recruited from a university-sponsored professional development conference focused on current best practices in speech-language pathology. Respondents completed an online survey that included questions about their own practices, as well as their overall perspectives on the usefulness of simplifying language input in different ways. Results The vast majority of SLPs (82%) reported using telegraphic input. SLPs reported using telegraphic input more frequently when prompting for verbal imitations than when describing play or providing a directive/request. Surprisingly, only 30% of SLPs who reported using telegraphic input felt that it was useful. SLPs reported that receptive language is the most important child characteristic to consider when deciding what kind of language input to provide. Conclusions These findings suggest the need for more purposeful clinical decision making in the context of providing simplified language input. In addition, in-depth, qualitative studies are needed to characterize the complex interactions among beliefs, experiences, practices, and perspectives pertaining to simplified language input.

Abstract
This study followed children with Autism Spectrum Disorder (ASD) from early intervention into their early schooling years, when they were aged between 6 and 9 years, on autism symptom severity and cognitive functioning. The children, matched at pre-intervention, were compared on type of community provided service: 31 were in receipt of community-based group Early Start Denver Model and 28 had received other community provisions for ASD. Irrespective of groups, cognitive functioning was found to have significantly improved by school age compared to pre-intervention. Autism symptom severity increased during the same developmental period, seemingly driven by an increase in restricted and repetitive behaviours over time. In contrast, both groups displayed improved social affect by school age.

Abstract
Naturalistic developmental behavioral intervention is an emerging class of interventions for young children with autism spectrum disorder. The present article is a meta-analysis of outcomes of group-design studies ( n = 27) testing interventions using naturalistic developmental behavioral intervention strategies. Small, significant positive effects of naturalistic developmental behavioral intervention were found for expressive language ( g = 0.32), reduction in symptoms of autism spectrum disorder ( g = −0.38), and play skills ( g = 0.23). Larger effects were found for social engagement ( g = 0.65) and overall cognitive development ( g = 0.48). A marginal effect was found for joint attention ( g = 0.14) and receptive language ( g = 0.28). For joint attention, improvement was moderated by hours of professional involvement. Evidence of publication and reporting bias was present for language outcomes. This meta-analysis grows the evidence base for naturalistic developmental behavioral interventions, particularly in the key areas of social engagement and cognition.

Abstract
OBJECTIVES Data indicate that some developmentally and behaviorally based early intervention programs can lead to a range of improvements in children with autism spectrum disorder. However, many such programs call for a fairly intensive amount of intervention. The objective of this preliminary study was to evaluate the effectiveness of a low-intensity therapist delivered intervention for young children with autism spectrum disorder. METHODS The study evaluated the outcomes of 3 hours per week of therapist-delivered early start Denver model intervention (ESDM) over a 12-week period for four preschool-aged boys with autism spectrum disorder. The effects of intervention on communication, imitation, and engagement were evaluated using a non-concurrent multiple probe across participants design. RESULTS Following the intervention, all four children showed increases in imitation, engagement, and either functional utterances or intentional vocalizations. These results were maintained after 4 weeks and mostly generalized to each child's mother. CONCLUSION These preliminary results suggest that low-intensity therapist delivered ESDM intervention may be of some benefit to children with autism spectrum disorder.

Abstract
OBJECTIVE To investigate the clinical effect of the Early Start Denver Model (ESDM) in children with autism spectrum disorder (ASD). METHODS Forty children aged 2-5 years who were diagnosed with ASD from September 2017 to January 2018 were enrolled in the study and were randomly divided into conventional intervention group and ESDM intervention group (n=20 each). Both groups were assessed by the Aberrant Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Clinical Global Impression-Severity (CGI-S) scale before intervention and by the ABC, CARS, CGI-S scale, and Clinical Global Impression-Improvement (CGI-I) scale after 3 months of intervention. RESULTS After 3 months of intervention, the total scores of ABC and CARS were both significantly decreased in the two groups (P<0.01); the scores on the social withdrawal and hyperactivity subscales of ABC were significantly decreased in the conventional intervention group (P<0.01), and the scores on the mood swings, social withdrawal, hyperactivity, and stereotyped behavior subscales of ABC were significantly decreased in the ESDM intervention group (P<0.01). Compared with the conventional intervention group, the ESDM intervention group had significantly greater changes in total score of ABC, scores on three subscales of ABC (mood swings, social withdrawal, and hyperactivity), and total score of CARS after intervention (P<0.05). After 3 months of intervention, the CGI-I scoring system showed that the disease improvement was significantly better in the ESDM intervention group than in the conventional intervention group (P<0.05). CONCLUSIONS Both conventional intervention and ESDM intervention can improve the social withdrawal and hyperactivity in children with ASD aged 2 to 5 years, but ESDM is more effective in improving the aberrant behavior of children with ASD.

Abstract
A major topic of debate is whether children with autism spectrum disorder should be educated in inclusive or specialized settings. We examined the feasibility and preliminary effectiveness of delivering the Group-Early Start Denver Model to children with autism spectrum disorder in inclusive versus specialized classrooms. We randomly assigned 44 preschoolers with autism spectrum disorder to receive the Group-Early Start Denver Model across one school calendar year in classrooms that included only children with autism spectrum disorder or mostly children who were typically developing. Blind-rated indicators of teaching quality showed similar results across settings, which were above the local benchmark. Children showed improvements across blinded proximal measures of spontaneous vocalization, social interaction, and imitation and across distal measures of verbal cognition, adaptive behavior, and autism symptoms irrespective of intervention setting. Mothers of participants experienced a reduction in stress irrespective of child intervention setting. Across both settings, age at intervention start was negatively associated with gains in verbal cognition. Delivery of Group-Early Start Denver Model in an inclusive setting appeared to be feasible, with no significant differences in teaching quality and child improvements when the program was implemented in inclusive versus specialized classrooms.

Abstract
Fundamental movement skill (FMS) assessment in preschools allows for early intervention; however it is unclear what assessments are feasible. The purpose of this review is to systematically review the feasibility of FMS assessments for pre-school aged children. The search was conducted across four databases, MEDLINE, Scopus, ERIC and SportsDiscus. Search terms included synonyms of "fundamental movement skills" and "pre-school children". Inclusion criteria were: (i) FMS assessment; (ii) feasibility data; (iii) assessment of children aged three to six years; (iv) assessment of typically developing children; and (v) peer reviewed full text publications in English. Feasibility concepts (administration time, equipment, space, assessment type, item, training, qualification) were each coded as 'poor = 1', 'average = 2' and 'good = 3'; potential total of 21. A total of 330 full text articles were considered but a quarter (n = 86) were excluded due to no feasibility data. Sixty-five studies using 13 different FMS assessments were included. The Athletic Skills Track and DEMOST-PRE assessments were most feasible (18/21) and the Test of Gross Motor Development and Movement Assessment Battery for Children were common but among the least feasible (12-14/21). This review allows pre-school staff to choose a FMS assessment based on feasibility. Future studies need to present feasibility of assessments.

Abstract
BACKGROUND The finding of positive outcomes at the group level for children with autism spectrum disorder (ASD) who complete comprehensive early intervention programmes often masks considerable individual variability. We therefore aimed to identify subgroups of children based on their response to intervention and to compare outcome variables between groups at two points in time. METHOD We used model-based cluster analysis to explore response to intervention using a longitudinal design for 210 children with ASD who had completed an early intervention programme. Children were assessed on entry at time 1 and again at time 2, which was after 12 months or when they exited the programme (whichever came first) using measures of ASD symptoms (Social Communication Questionnaire), cognition (Mullen Scales of Early Learning) and adaptive behaviour (Vineland Adaptive Behaviour Scales-II). RESULTS A two-cluster solution was identified, including a high change group who improved consistently more than the low change group across measures, and showed significantly fewer autism symptoms, higher non-verbal and verbal cognition and adaptive behaviour composite scores at time 1. CONCLUSIONS The findings indicated that children's response to early intervention is not uniform but instead included subgroups characterised by patterns of high and low change. Further research is needed to identify clinically relevant mediators of differential response group membership.

Effects of Parent-Implemented Early Start Denver Model Intervention on Chinese Toddlers with Autism Spectrum Disorder: A Non-Randomized Controlled Trial. Autism Res 2018; 11:654-666. [PMID: 29412514 DOI: 10.1002/aur.1917] [Citation(s) in RCA: 53] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Revised: 11/15/2017] [Accepted: 12/08/2017] [Indexed: 01/12/2023]
Abstract
To evaluate the effects of a 26-week, high-intensity, parent-implemented Early Start Denver Model (P-ESDM) intervention on developmental outcomes, severity of autism spectrum disorder (ASD), and parental stress of ASD toddlers in China. Subjects in P-ESDM group (n = 23) were recruited from 1.5- to 2.5-year-old toddlers who were screened positive in Xuhui and Minhang Districts and were diagnosed with ASD. A community (comparison) group of age-matched toddlers with ASD (n = 20) was recruited from other areas. Subjects of the P-ESDM group attended 1.5-hr parent coaching per week for 26 weeks, and those in the community group received interventions available from communities. Assessments were conducted at baseline (T1) and 26 weeks later (T2). After adjusting for baseline differences between the two groups, P-ESDM group demonstrated greater improvement than the community group in general development, especially in Language domain. Neither group demonstrated significant change in ASD severity, but the P-ESDM group showed greater improvement in social affect, parent-reported social communication and symbolic play than community group did. Finally, parents in P-ESDM group experienced decreased parenting stress while those in community group showed an opposite trend, though the differences did not reach significant association with the P-ESDM intervention. Chinese toddlers with ASD receiving 26 weeks of P-ESDM via regular coaching sessions showed significant greater improvement than those receiving community interventions in multiple aspects of development including social communications. These findings add support to the importance of providing early screening, diagnosis, and immediate referral for evidence-based interventions to improve outcome of young children with ASD. Autism Res 2018, 11: 654-666. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY The development of early screening and diagnosis of autism spectrum disorder (ASD) in China has highlighted the importance of early intervention for young children with ASD. Our current study demonstrated that parent-implemented Early Start Denver Model (P-ESDM) via coaching from professionals improved developmental outcomes, especially in the language domain, and social communicational behaviors of Chinese toddlers with ASD. P-ESDM may help parents in China provide effective early intervention to their children with ASD via improving their skills when they are still at a waiting list for services or lack access to intervention, and has the potential to alleviate their parenting stress.

Abstract
The Early Start Denver Model (ESDM) is an intervention program recommended for pre-schoolers with autism ages 12-48 months. The rationale for this recommendation is the potential for intervention to affect developmental trajectories during early sensitive periods. We investigated outcomes of 32 children aged 18-48 months and 28 children aged 48-62 months receiving the ESDM for one year (approximately 20 h per week). Younger children achieved superior verbal DQ gains compared to their older counterparts. There were no group differences with respect to non-verbal DQ and adaptive behavior (with both age-groups undergoing significant change), or ASD severity (with neither age-group showing improvements on the ADOS). The association between verbal DQ gains and age at intake was moderated by baseline verbal level.

Abstract
Background Exploring ways to improve the trajectory and symptoms of autism spectrum disorder is prevalent in research, but less is known about the natural prognosis of autism spectrum disorder and course of symptoms. The objective of this study was to examine the temporal stability of autism spectrum disorder and autism diagnosis, and the longitudinal trajectories of autism core symptom severity. We furthermore sought to identify possible predictors for change. Methods We searched PubMed, PsycInfo, EMBASE, Web of Science, Cochrane Library up to October 2015 for prospective cohort studies addressing the autism spectrum disorder/autism diagnostic stability, and prospective studies of intervention effects. We included people of all ages with autism spectrum disorder/autism or at risk of having autism spectrum disorder, who were diagnosed and followed up for at least 12 months using the Autism Diagnostic Observation Schedule (ADOS). Both continuous ADOS scores and dichotomous diagnostic categories were pooled in random-effects meta-analysis and meta-regression. Results Of 1443 abstracts screened, 44 were eligible of which 40 studies contained appropriate data for meta-analysis. A total of 5771 participants from 7 months of age to 16.5 years were included. Our analyses showed no change in ADOS scores across time as measured by Calibrated Severity Scores (mean difference [MD] = 0.05, 95% CI -0.26 to 0.36). We observed a minor but statistically significant change in ADOS total raw scores (MD = -1.51, 95% CI -2.70 to -0.32). There was no improvement in restricted and repetitive behaviours (standardised MD [SMD] = -0.04, 95% CI -0.19 to 0.11), but a minor improvement in social affect over time (SMD = -0.31, 95% CI -0.50 to -0.12). No changes were observed for meeting the autism spectrum disorder criteria over time (risk difference [RD] = -0.01, 95% CI -0.03 to 0.01), but a significant change for meeting autism criteria over time (RD = -0.18, 95% CI -0.29 to -0.07). On average, there was a high heterogeneity between studies (I2 range: 65.3% to 93.1%). Discussion While 18% of participants shifted from autism to autism spectrum disorder diagnosis, the overall autism spectrum disorder prevalence was unchanged. Overall autism core symptoms were remarkably stable over time across childhood indicating that intervention studies should focus on other areas, such as quality of life and adaptive functioning. However, due to high heterogeneity between studies and a number of limitations in the studies, the results need to be interpreted with caution.

Cost Offset Associated With Early Start Denver Model for Children With Autism. J Am Acad Child Adolesc Psychiatry 2017; 56:777-783. [PMID: 28838582 PMCID: PMC7007927 DOI: 10.1016/j.jaac.2017.06.007] [Citation(s) in RCA: 76] [Impact Index Per Article: 10.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Revised: 05/23/2017] [Accepted: 06/28/2017] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To determine the effect of the Early Start Denver Model (ESDM) for treatment of young children with autism on health care service use and costs. METHOD We used data from a randomized trial that tested the efficacy of the ESDM, which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents, for 2 years. Parents were interviewed about their children's service use every 6 months from the onset of the intervention to follow-up (age 6 years). The sample for this study consisted of 39 children with autism who participated in the original randomized trial at age 18 to 30 months, and were also assessed at age 6 years. Of this sample, 21 children were in the ESDM group, and 18 children were in the community care (COM) group. Reported services were categorized and costed by applying unit hourly costs. Annualized service use and costs during the intervention and post intervention for the two study arms were compared. RESULTS During the intervention, children who received the ESDM had average annualized total health-related costs that were higher by about $14,000 than those of children who received community-based treatment. The higher cost of ESDM was partially offset during the intervention period because children in the ESDM group used less applied behavior analysis (ABA)/early intensive behavioral intervention (EIBI) and speech therapy services than children in the comparison group. In the postintervention period, compared with children who had earlier received treatment as usual in community settings, children in the ESDM group used less ABA/EIBI, occupational/physical therapy, and speech therapy services, resulting in significant cost savings in the amount of about $19,000 per year per child. CONCLUSION Costs associated with ESDM treatment were fully offset within a few years after the intervention because of reductions in other service use and associated costs.
