Understanding the Effects of Naturalistic Developmental Behavioral Interventions: A Project AIM Meta‐analysis

Autism and Communication Skills: Perspectives of Special Education Teachers in Saudi Arabia

The experiences of special education teachers in Saudi Arabia are quite different from the experiences of their counterparts from other countries as they work in a unique culture and educational system. The educational system in Saudi Arabia is gender segregated, and the Saudi Arabian Ministry of Education (MoE) provides an equal budget, salaries, and subsidies and implements the same policies and uses the same curriculum regardless of the location, size of the city, or the number of students. This country's unique characteristics may influence special education teachers' experiences, which raises the need to investigate and understand the experiences of Saudi special education teachers. We sought to understand the experiences of special education teachers in Saudi Arabia, focusing on teaching communication skills to autistic students. We conducted semi-structured interviews with 13 Saudi special education teachers to gain deeper insights into the experiences of these teachers within the Saudi context. The themes that emerged from the interviews revolved around evaluating and teaching communication skills, the role of the Saudi MoE, and the perceived challenges and needs related to teaching communication skills. Building on our findings, we propose a set of recommendations for special education teachers and the Saudi MoE.

Comparative effectiveness trial: Modular behavior approach for young autistic children compared to comprehensive behavioral intervention

This 24-week single-blind trial tested a modular approach for young autistic children (MAYAC) that was delivered for fewer hours per week and modified based on child progress and parental input compared to comprehensive behavioral intervention treatment as usual (CBI, TAU). Participants were autistic children, ages 18-60 months of age. MAYAC was initially 5 h of intervention per week, one of which was parent training and the other four direct therapy focusing on social communication and engagement, but additional modules could be added for up to 10 h per week. Comprehensive behavior intervention was delivered for ≥15 h per week. Outcome measures included the Vineland Adaptive Behavior Scales; VABS, the Ohio Autism Clinical Improvement Scale - Autism Severity; OACIS - AS and the Pervasive Developmental Disorder Behavior Inventory - Parent; PDDBI-P. Implementation and parent satisfaction measures were also collected. Fifty-six children, mean age of 34 months, were randomized. Within-group analysis revealed significant improvements from baseline to week 24 for both MAYAC (p < 0.0001) and CBI, TAU (p < 0.0001) on the VABS. The noninferiority test was performed to test between group differences and MAYAC was not inferior to CBI, TAU on the VABS (p = 0.0144). On the OACIS - AS, 48.0% of MAYAC and 45.5% of CBI were treatment responders there were no significant changes on the PDDBI-P, for either group. Treatment fidelity was high for both groups (>95%) as was parent satisfaction. Findings from this small trial are promising and suggest MAYAC may be an alternative for some young autistic children and their families to CBI, TAU.

Telehealth coaching in Project ImPACT indirectly affects children's expressive language ability through parent intervention strategy use and child intentional communication: An RCT

Parent-mediated, naturalistic developmental behavioral interventions (NDBIs) are a promising approach for supporting social communication development in young autistic children. This study examined the effect of telehealth delivery of a parent-mediated NDBI, Project ImPACT, on children's expressive language ability using a randomized control trial with intent-to-treat analysis. Sixty-four young autistic children and their primary caregiver were matched on age and developmental quotient and randomly assigned to receive 6 months of therapist-assisted Project ImPACT (i.e., telehealth coaching), self-directed Project ImPACT, or an active control. Parent-child interactions were recorded at intake and immediately post-treatment, and the children's expressive language skills were assessed at intake and a 9-month follow-up using standardized measures. Although there was no total effect of treatment group assignment on child outcomes, a serial mediation analysis revealed that therapist-assisted ImPACT had an indirect effect on children's expressive language ability at follow-up through their parents' use of the intervention strategies and their intentional communication immediately post-treatment. Findings support Project ImPACT's program theory and highlight the importance of coaching in achieving positive outcomes when delivered via telehealth.

Feasibility of the Autism Navigator® JumpStart to Coaching in Everyday Activities course in South Africa

LAY ABSTRACT

In low-resource settings, non-profit organisations play an essential role in providing services and support for families with young children with autism, including in Africa. However, non-profit organisation service providers may not have access to quality training in proven intervention methods. Web-based or online courses may help to meet this need. In this study, we invited a group of specialist (10) and non-specialist (16) non-profit organisation providers in South Africa to complete a web-based course, Autism Navigator® JumpStart to Coaching in Everyday Activities, a 20-h self-paced course that provides training in an evidence-based parent coaching intervention called Early Social Interaction. We evaluated acceptability, appropriateness, and feasibility of the training. Of the 26 who enrolled, 16 completed the course (7 specialists and 9 non-specialists). All providers found it difficult to find time to do the course until the lockdown restrictions due to COVID-19, when most completed the course. Those whose first language was not English experienced more difficulties with two of six learner assessments and those who were not clinical specialists had more difficulty with the coaching strategies learner assessment. Most providers rated the course highly feasible, acceptable, and appropriate stating that the course content was very valuable and helpful in equipping them to serve their families. They felt the extensive video clips and regular meetings with a local trainer helped them engage with and understand the material. They suggested that including South African video clips would make the course more relatable. The fact that the course was web-based was identified as a strong benefit, especially during COVID-19 restrictions.

Do Naturalistic Developmental Behavioral Interventions improve family quality of life? A systematic review and meta-analysis

LAY ABSTRACT

Naturalistic Developmental Behavioral Interventions have been described as culturally responsive and family-friendly interventions, with research demonstrating improvements in children's development following the receipt of these interventions. Given the child-directed nature of Naturalistic Developmental Behavioral Interventions and the intervention's integration within families' daily routines, many studies have examined the impact of Naturalistic Developmental Behavioral Interventions on family and family member quality of life. We conducted a systematic review and meta-analysis to explore the relationship between Naturalistic Developmental Behavioral Interventions and family quality of life. Results suggest that the provision of a Naturalistic Developmental Behavioral Intervention neither improved nor worsened family or family member quality of life. For those involved in delivering Naturalistic Developmental Behavioral Intervention services, there is an immediate need to convey to families that children's improvements will likely not translate into improvements in family quality of life.

Determining Associations Between Intervention Amount and Outcomes for Young Autistic Children: A Meta-Analysis

Importance

Health professionals routinely recommend intensive interventions (ie, 20-40 hours per week) for autistic children. However, primary research backing this recommendation is sparse and plagued by methodological flaws.

Objective

To examine whether different metrics of intervention amount are associated with intervention effects on any developmental domain for young autistic children.

Data Sources

A large corpus of studies taken from a recent meta-analysis (with a search date of November 2021) of early interventions for autistic children.

Study Selection

Studies were eligible if they reported a quasi-experimental or randomized clinical trial testing the effects of a nonpharmacological intervention on any outcome in participant samples comprising more than 50% autistic children 8 years or younger.

Data Extraction and Synthesis

Data were independently extracted by multiple coders. Meta-regression models were constructed to determine whether each index of intervention amount was associated with effect sizes for each intervention type, while controlling for outcome domain, outcome proximity, age of participants, study design, and risk of detection bias. Data were analyzed from June 2023 to February 2024. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Main Outcomes and Measures

The primary predictor of interest was intervention amount, quantified using 3 different metrics (daily intensity, duration, and cumulative intensity). The primary outcomes of interest were gains in any developmental domain, quantified by Hedges g effect sizes.

Results

A total of 144 studies including 9038 children (mean [SD] age, 49.3 [17.2] months; mean [SD] percent males, 82.6% [12.7%]) were included in this analysis. None of the meta-regression models evidenced a significant, positive association between any index of intervention amount and intervention effect size when considered within intervention type.

Conclusions and Relevance

Findings of this meta-analysis do not support the assertion that intervention effects increase with increasing amounts of intervention. Health professionals recommending interventions should be advised that there is little robust evidence supporting the provision of intensive intervention.

Examining Cultural and Linguistic Sensitivity of Pathways Early Autism Intervention with Hispanic Families

PURPOSE

This research aimed to evaluate evidence of Pathways parent-mediated early autism intervention as a culturally and linguistically sensitive intervention (CLSI) for Hispanic families with autistic children.

METHODS

We used Bernal et al.'s ecologically valid (EV) framework to evaluate current practice and Hispanic parents' perceptions of Pathways 1 ½ years after completing the intervention. Both quantitative and qualitative methods were used. Nineteen parents were contacted, of which 11 completed a semi-structured interview about their experience with Pathways.

RESULTS

On average, the group that completed the interview was less educated, had more monolingual Spanish speakers, and rated their general experience with the intervention slightly more positively than those who did not agree to complete the interview. A review of Pathways's current practices through the lens of the EV framework suggested that Pathways was a CLSI for Hispanic participants in the domains of context, methods, language, and persons. Parental interviews echoed these strengths. However, Pathways did less well balancing evidence-based intervention strategies for autistic children with the heritage value of respeto.

CONCLUSION

Pathways demonstrated strengths regarding cultural and linguistic sensitivity for Hispanic families with young autistic children. Future work with our community stakeholder group will integrate heritage and majority culture perspectives to strengthen Pathways as a CLSI.

Characterizing mechanisms of caregiver-mediated naturalistic developmental behavioral interventions for autistic toddlers: A randomized clinical trial

LAY ABSTRACT

Caregiver-mediated early interventions support caregivers' use of strategies to improve their young autistic child's communication. In the current clinical trial, we sought to isolate the most effective strategies to improve short-term and long-term child communication outcomes. Results demonstrated how children may benefit from caregiver prompts to facilitate long-term language outcomes. In conclusion, the current study improves our understanding of how early intervention facilitates child communication outcomes.

Caregiver Narratives of Children with Autism Spectrum Disorder: Exploring Symptom Recognition, Diagnosis, and Interventions

The diagnosis of autism spectrum disorder (ASD) poses myriad challenges for families, yet there is a scarcity of research focusing on their journey from recognizing initial anomalies to implementing interventions. This qualitative study examines how caregivers in Sylhet, Bangladesh, perceive and manage ASD in their children, including early symptom identification, diagnostic processes, and intervention strategies. Data for this study were collected through semi-structured interviews, case studies, and observations involving 22 caregivers of children with ASD. Participants were chosen using purposive-convenience sampling, and data collection continued until interpretive saturation was achieved. The study findings unveil nuanced caregiver perceptions of ASD causation, influenced by sociocultural factors, religious beliefs, and genetic predispositions. These determinants wield significant influence over treatment modalities and the child's developmental trajectory. Importantly, the prevalence of supernatural beliefs and myths often surpasses biomedical explanations, highlighting gaps in awareness, educational outreach, and understanding of ASD. Nevertheless, religious beliefs and rituals concurrently serve as adaptive coping mechanisms, offering solace amidst uncertainty. Furthermore, a striking observation emerges: despite parents frequently identifying anomalies in their children within a 24-month, a substantial delay of 3 to 5 years persists between initial symptom recognition and formal diagnosis. This delay predominantly stems from caregiver hesitancy driven by societal stigmatization, familial dismissal attitudes, and limited diagnostic and specialized services. This study highlights the challenging diagnostic journey and caregiving for children with ASD in Bangladesh, stressing the need for systemic improvements in services, awareness, and research to enhance the well-being of individuals with ASD.

The Role of Pathways Early Autism Intervention in Improving Social Skills and Respeto for Young Hispanic Autistic Children

PURPOSE

We know very little about Hispanic autistic children's response to intervention as, historically, Hispanic children are underrepresented in intervention studies. Pathways parent-mediated early autism intervention is one of the few naturalistic developmental behavioral interventions (NDBIs) that is contextually and linguistically responsive to Hispanic families. However, some child-centered NDBI strategies do not align with the Hispanic caregiving value of respeto. A child exhibiting respeto demonstrates affiliative obedience by displaying deference and respect toward adults. Furthermore, theories of the ontogeny of cultural learning suggest that certain levels of social development may be necessary to learn cultural values. The current study investigates (1) the relationship between Hispanic autistic children's social skills and affiliative obedience and (2) the efficacy of Pathways in improving affiliative obedience in Hispanic children.

METHODS

This quasi-experimental design study used preexisting standardized test data and video recordings from 26 Hispanic participants who took part in a previous Pathways efficacy study. Recordings were coded for affiliative obedience and social connectedness. Residual change variables were used to measure progress from baseline to post-intervention, and correlation and hierarchical regression analyses were conducted to analyze the data.

RESULTS

We found significant positive correlations between social skills and children's affiliative obedience for baseline and change variables. In addition, we found Pathways had a significant medium-large magnitude effect on change in affiliative obedience skills.

CONCLUSION

This study highlights the benefits of NDBI interventions that advance social development in autistic children and support Hispanic parents in enculturating their children in the value of respeto.

Addressing disruptive behaviors within naturalistic developmental behavioral interventions: Clinical decision-making, intervention outcomes, and implications for practice

LAY ABSTRACT

Naturalistic developmental behavioral interventions are a common and well-researched type of intervention for young autistic children that focus on supporting social communication. These interventions often do not include formal guidelines on how to address disruptive behaviors, even though they are common among autistic children. This study measured how often clinicians delivering a specific naturalistic developmental behavioral intervention, Project ImPACT, adapted how they delivered the program to address disruptive behavior, and how these adaptations related to children's social communication outcomes at the end of their participation in the intervention. We also spoke with clinicians about how they address disruptive behavior and emotion regulation during their sessions. In this study, clinicians adapted Project ImPACT to address disruptive behaviors in about one-third of all sessions. These adaptations did not affect children's social communication outcomes. Clinicians discussed how they felt social communication, disruptive behavior, and emotion regulation are linked to one another and that they often try to integrate intervention strategies to address each of these areas. However, they note that a clinicians' approach to addressing disruptive behavior might vary depending on their level of training and experience. These results indicate several future directions for supporting clinicians in addressing behavior and regulation effectively within these types of interventions.

Neural correlates of response to joint attention in 2-to-5-year-olds in relation to ASD and social-communicative abilities: An fNIRS and behavioral study

Autism spectrum disorder (ASD) is associated with life-long challenges with social cognition, and one of its earliest and most common manifestations is atypical joint attention, which is a pivotal skill in social-cognitive and linguistic development. Early interventions for ASD children often focus on training initiation of joint attention (IJA) and response to joint attention bids (RJA), which are important for social communication and cognition. Here, we used functional near-infrared spectroscopy and behavioral measures to test typically developing (TD, n = 17) and ASD children (n = 18), to address the relationship between the neural correlates of RJA and social-communicative behavior. Group-level differences were present for RJA-specific activation over right temporal sites, where TD children showed higher levels of activation during RJA than ASD children, whereas the two groups did not differ in the control condition. Correlations between neural activation and behavioral traits suggest that, in ASD children, neural activation during RJA is related to the frequency of RJA behavior when the former is measured over left temporal sites, and to social affect symptoms when considered for right temporal sites. Possible implications of the evidenced correlations are discussed.

Generalisation of Social Communication Skills by Autistic Children During Play-Based Assessments Across Home, School and an Unfamiliar Research Setting

We investigated autistic children's generalisation of social communication over time across three settings during a play-based assessment with different adults and explore the potential moderating effects on generalisation of age, nonverbal IQ and level of restricted and repetitive behaviours. The social communication abilities of 248 autistic children (2-11 years, 21% female, 22% single parent, 60% white) from three UK sites were assessed from 1984 video interactions in three contexts with three different interaction partners (parent/home, teaching assistant/school, researcher/clinic) at baseline, midpoint (+ 7m) and endpoint (+ 12m) within the Paediatric Autism Communication Trial-Generalised (PACT-G), a parent-mediated social communication intervention. Children's midpoint social communication at home generalised to school at midpoint and to clinic at endpoint. Generalisation was stronger from home to school and clinic than school to home and clinic. Generalisation was not moderated by age, nonverbal IQ or restricted and repetitive behaviour. Broader child development did not explain the pattern of results. The current study is the largest study to date to explore generalisation with autistic children and provides novel insight into their generalisation of social communication skills. Further research is needed to gain a more comprehensive understanding of facilitators of generalisation across settings and interaction partners in order to develop targeted strategies for interventions to enhance outcomes for young autistic children.

Comparison of the efficacy of parent-mediated NDBIs on developmental skills in children with ASD and fidelity in parents: a systematic review and network meta-analysis

BACKGROUND

Recently, studies on behavioral interventions for autism have gained popularity. Naturalistic Developmental Behavior Interventions (NDBIs) are among the most effective, evidence-based, and widely used behavior interventions for autism. However, no research has been conducted on which of the several NDBI methods is most effective for parents and children with autism spectrum disorders. Therefore, we conducted a network meta-analysis to compare the specific effects of each type of parental-mediated NDBI on children's developmental skills and parent fidelity.

METHODS

PubMed, Embase, Cochrane Library, Medline, Web of Science, China National Knowledge Infrastructure (CNKI), CINAHL, and Wanfang databases were searched from inception to August 30, 2023. A total of 32 randomized controlled trial studies that examined the efficacy of different NDBIs were included.

RESULTS

Parents of children with ASD who received Pivotal Response Treatment (PRT) reported significant improvements in their children's social skills (SUCRA, 74.1%), language skills (SUCRA, 88.3%), and parenting fidelity (SUCRA, 99.5%). Moreover, parents who received Early Start Denver Model (ESDM) reported significant improvements in their children's language (SMD = 0.41, 95% CI: 0.04, 0.79) and motor skills (SMD = 0.44, 95% CI: 0.09, 0.79). In terms of the efficacy of improving parent fidelity, the results showed that the Improving Parents as Communication Teachers (ImPACT) intervention significantly improved parent fidelity when compared with the treatment-as-usual group (TAU) (SMD = 0.90, 95% CI: 0.39, 1.42) and the parental education intervention (PEI) (SMD = 1.10, 95% CI:0.28, 1.91).There was a difference in parent fidelity among parents who received PRT(SMD = 3.53, 95% CI: 2.26, 4.79) or ESDM(SMD = 1.42, 95% CI: 0.76, 2.09) training compared with PEI.

CONCLUSION

In conclusion, this study revealed that parents can achieve high fidelity with the ImPACT intervention, and it can serve as an early first step for children newly diagnosed with ASD. It also showed that parent-mediated ESDM is effective in improving language and motor skills for children with ASD and can be used as part of the second stage of parent training. Parent-mediated PRT can also be used as a third stage of parent training with sufficient training intensity to further improve language, social, and motor skills.

"It just depends": Parent, teacher, and expert conceptualization of social communication in young autistic children

LAY ABSTRACT

Improving social communication is often one goal during early autism services. However, researchers do not yet know whether their ideas about which social communication skills should be targeted during services for young autistic children are the same as the goals of autism community members, such as parents, teachers, and expert clinicians. This study used focus groups (meetings of small groups of community members) to ask people from these groups about what aspects of social communication are most important to support in young autistic children. A total of 43 people participated in these focus groups. These groups included parents (three groups; 21 people), teachers (two groups; 8 people), and experts in early social communication and autism (two groups; 14 people). Focus group participants talked about several aspects of social communication that were already familiar to the research team, such as problems with expressive communication, language understanding, and social interaction. However, participants also talked about several parts of social communication that were less familiar to the research team and had usually not been mentioned in previous research. These included (1) considering the value of unusual forms of communication, (2) taking context and setting into account when considering social communication, and (3) how communication and emotion regulation impact one another. The information from these focus groups will be helpful to making sure that researchers and clinicians focus their social communication supports on areas that are most important to parents and teachers.

Seeking Validation and Creating Meaningful Interactions: Perceptions of a Parent-Mediated Infant Intervention

Infancy, a formative period for development, has been identified as an advantageous time to provide family-centered support for children with delays. Families should be included as stakeholders during development of such interventions to ensure social value. We describe a preliminary randomized controlled trial evaluating Infant Achievements (IA), an 8-week (16-session) parent-mediated intervention for parents of infants 8-12 months old with social communication delays. This study reports our qualitative examination of the intervention's social validity. We conducted focus groups with 7 IA parent participants and analyzed their responses using conventional content analysis. Five themes emerged: (a) difficulty identifying resources to address concerns, (b) seeking validation of concerns, (c) seeking support to enhance children's development, (d) experiencing a supportive coaching relationship, and (e) creating meaningful interactions to support children's communication and social skills. Our results emphasize the necessity of partnering with families in the development of evidence-based family-centered interventions for infants with developmental delays to maximize their social value.

The Social Validity of Behavioral Interventions: Seeking Input from Autistic Adults

Many in the autistic community have expressed concerns regarding the use of behavioral interventions with autistic children, suggesting that these interventions may not be socially valid. Though behavioral interventions have evolved to be more naturalistic and child-centered, little structured research has been done to explicitly seek autistic perspectives on the acceptability of specific components of behavioral interventions. Autistic adults (N = 235) were recruited online to take the Autism Intervention Attitudes Scale (AIAS), a questionnaire designed to gather feedback on common intervention goals and practices. Results indicate that participants find goals and practices that highlight quality of life, safety, and autistic interactions acceptable, while those that focus on normalization based on neurotypical standards are not. An exploratory graph analysis revealed three communities of goals ("uncontroversial goals", "controversial goals", and "social goals"). Comparison between naturalistic and structured intervention components additionally showed that autistic participants favored naturalistic strategies. These findings are in line with known criticisms of behavioral intervention from autistic adults, but also provide more information on the specific ways in which behavioral interventions can be reformed. This information can guide professionals in the development of appropriate goals and decisions around intervention planning.

Mediation of 6-year mid-childhood follow-up outcomes after pre-school social communication (PACT) therapy for autistic children: randomised controlled trial

BACKGROUND

There are very few mechanistic studies of the long-term impact of psychosocial interventions in childhood. The parent-mediated Paediatric Autism Communication Therapy (PACT) RCT showed sustained effects on autistic child outcomes from pre-school to mid-childhood. We investigated the mechanism by which the PACT intervention achieved these effects.

METHODS

Of 152 children randomised to receive PACT or treatment as usual between 2 and 5 years of age, 121 (79.6%) were followed 5-6 years after the endpoint at a mean age of 10.5 years. Assessors, blind to the intervention group, measured Autism Diagnostic Observation Scale Calibrated Severity Score (ADOS CSS) for child autistic behaviours and Teacher Vineland (TVABS) for adaptive behaviour in school. Hypothesised mediators were child communication initiations with caregivers in a standard play observation (Dyadic Communication Measure for Autism, DCMA). Hypothesised moderators of mediation were baseline child non-verbal age equivalent scores (AE), communication and symbolic development (CSBS) and 'insistence on sameness' (IS). Structural equation modelling was used in a repeated measures mediation design.

RESULTS

Good model fits were obtained. The treatment effect on child dyadic initiation with the caregiver was sustained through the follow-up period. Increased child initiation at treatment midpoint mediated the majority (73%) of the treatment effect on follow-up ADOS CSS. A combination of partial mediation from midpoint child initiations and the direct effect of treatment also contributed to a near-significant total effect on follow-up TVABS. No moderation of this mediation was found for AE, CSBS or IS.

CONCLUSIONS

Early sustained increase in an autistic child's communication initiation with their caregiver is largely responsible for the long-term effects from PACT therapy on autistic and adaptive behaviour outcomes. This supports the theoretical logic model of PACT therapy but also illuminates fundamental causal processes of social and adaptive development in autism over time: early social engagement in autism can be improved and this can have long-term generalised outcome effects.

Parent perspectives on treatment: A mixed methods analysis of PEERS® for Preschoolers

LAY ABSTRACT

Autistic children have social communication differences that can contribute to difficulties making and keeping friends, as well as poor mental health (e.g. anxiety, depression). Social skills training programs for preschoolers on the spectrum have been shown to increase social functioning and improve outcomes. Parent involvement in these programs is essential, as parents are able to use the intervention strategies outside of sessions. Teaching parents skills to help their children is also thought to reduce parenting stress through empowerment, knowledge, and social support. However, we still do not know much about how parents experience social skills treatments and whether there are specific parts that are especially helpful to them. This study examined parent perspectives on the University of California, Los Angeles Program for the Education and Enrichment of Relational Skills (PEERS®) for Preschoolers, an evidence-based, group social skills intervention for autistic young children who are struggling socially. Twenty-four parents reported on their child's progress through questionnaires and participated in semi-structured interviews that asked about their experiences and perspectives 1-5 years after completing (PEERS®) for Preschoolers. Parents reported that their children displayed increased social skills and confidence after (PEERS®) for Preschoolers, while parents described feeling more positive, supported, and having greater understanding of their child and their development. Those parents who continued to use strategies taught in (PEERS®) for Preschoolers, particularly priming and preparing their child for social activities, showed greater improvements in long-term child outcomes and parenting stress. Overall, findings show that parents had a positive experience during and after PEERS® for Preschoolers, finding the program helpful in multiple ways to both their child and to themselves as a parent.

Randomised Controlled Trial of a Behavioural Sleep Intervention, 'Sleeping Sound', for Autistic Children: 12-Month Outcomes and Moderators of Treatment

This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the Sleeping Sound group reported greater reduction in child sleep problems compared to TAU (p < .001, effect size: - 0.4). The long-term benefits of the intervention were greater for children taking sleep medication, children of parents who were not experiencing psychological distress, and children with greater autism severity. The Sleeping Sound intervention demonstrated sustained improvements in child sleep. Identified moderators may inform treatment by indicating which subgroups may benefit from further support.

Social Validity of Pivotal Response Treatment for Young Autistic Children: Perspectives of Autistic Adults

The social validity of autism behavioral intervention has been questioned. Naturalistic Developmental Behavioral Interventions (NDBIs) attempt to address some concerns, but it is unclear whether autistic people consider NDBIs socially valid. Social validity of an NDBI, Pivotal Response Treatment (PRT), was investigated through autistic adults commenting on videos of autistic children receiving PRT. Qualitative coding of responses generated three themes: respect for individuals; assessment of intervention implementation; and socioemotional considerations. Although video brevity limits the scope of the present study's conclusions, participants highlighted PRT components that appeared socially valid (e.g., reinforcing attempts, following the child's lead) and aspects appearing invalid (e.g., overemphasis on spoken language). Therefore, adjustments appear necessary for PRT to be fully acceptable to the autistic community.

Overview of Meta-Analyses on Naturalistic Developmental Behavioral Interventions for Children with Autism Spectrum Disorder

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.

Treatment mechanism of the WHO caregiver skills training intervention for autism delivered in community settings

This study examined the mechanism of effect of the WHO Caregiver Skills Training (CST) through secondary analysis of a pilot RCT conducted in community settings. Participants were 86 caregivers (77% mothers) of children with ASD (78% male, mean age: 44.8 months) randomized to CST (n = 43) or treatment as usual (n = 43). The primary outcomes, measured at baseline (t1), immediately post-intervention (t2), and 3 months post-intervention (t3), were derived from the coding of caregiver-child free play interactions with the Brief Observation of Social-Communication Change (BOSCC) and the Joint Engagement Rating Inventory scale (JERI). At t3 positive treatment main effects had been observed for caregiver skills supportive of the interaction and for flow of the interaction (JERI), albeit only non-significant changes in the expected direction for child outcomes: autism phenotypic behaviors (BOSCC), joint engagement and availability to interact (JERI). This study tested the theory of change of CST, hypothesizing that the intervention would lead to an improvement on all child and dyad outcomes through an increase in the caregiver skills supportive of the interaction. Serial mediation analyses revealed that the effect of the intervention was significantly influenced by change in caregiver skills. Participation in the intervention led to notable increases in caregiver skills at t2 and t3, which subsequently contributed to improvements at t3 in flow of the interaction, autism phenotypic behavior, joint engagement, and availability to interact. We confirmed our a priori hypothesis showing that change in caregiver skills significantly mediated the effect of treatment on the dyad primary outcome, as well as on the other child outcomes that had shown non-significant changes in the expected direction. Implications for intervention design and policy making in the context of public health services are discussed.

Acceptability and feasibility of a parent-mediated social-communication therapy for young autistic children in Brazil: A qualitative implementation study of Paediatric Autism Communication Therapy

LAY ABSTRACT

Parents of autistic children and health professionals who work with autistic children in Brazil had positive views about introducing Paediatric Autism Communication Therapy as a therapy for autistic children in Brazil. The parents and clinicians also mentioned some difficulties about using Paediatric Autism Communication Therapy in Brazil. We made adaptations to Paediatric Autism Communication Therapy to address these difficulties. Paediatric Autism Communication Therapy is a therapy to support the development of social and communication skills for autistic children aged 2-10 years. The therapy is conducted with the autistic child's parent. Paediatric Autism Communication Therapy has not been used in Brazil before. There are few therapy options available for autistic children in Brazil and we believed that Paediatric Autism Communication Therapy may be useful. We asked three groups of people in Brazil about their views of Paediatric Autism Communication Therapy, after explaining how the therapy works. Group 1 included 18 parents of autistic children aged 2-10 years. Group 2 included 20 health professionals such as psychologists who work with autistic children. Group 3 included 15 parents of autistic children aged 2-7 years who received the Paediatric Autism Communication Therapy. We learned that parents and clinicians felt that Paediatric Autism Communication Therapy would be a beneficial therapy for autistic children in Brazil. We also found out about the challenges of using Paediatric Autism Communication Therapy in Brazil. We used these findings to make small cultural adaptations to Paediatric Autism Communication Therapy to make it more suitable for Brazil.

Beyond the Task List: A Proposed Integration of Naturalistic Developmental Behavioral Interventions to BCBA Training

Naturalistic developmental behavioral intervention (NDBI) is firmly rooted in both the science of ABA as well as developmental science. Research indicates that many practicing board certified behavior analysts (BCBAs) are unfamiliar with NDBI models and do not implement these approaches when working with young autistic children (Hampton and Sandbank Autism, 26(4), 875-888, 2022). In this article we align NDBI to the seven dimensions of ABA, describe their compatibility with the ABA service system, and urge community agencies and insurance funders to support NDBI use. Finally, we provide a roadmap for BCBAs who provide behavior analytic intervention to young autistic children and for Verified Course Sequence faculty to effectively align the 6th edition BCBA Test Content Outline with the principles and application of NDBI.

Review of intervention methods for language and communication disorders in children with autism spectrum disorders

In recent years, the number of patients-particularly children-with autism spectrum disorder (ASD) has been continually increasing. ASD affects a child's language communication and social interaction to a certain extent and has an impact on behavior, intelligence level, and other aspects of the child. Data indicates that 40% to 70% of children with ASD experience language developmental delays, which are mainly manifested as lack of language or language developmental delay, self-talk, use of stereotyped language, parroting, et cetera. A language communication disorder is a major symptom of ASD and is the most common reason for patients to visit a doctor. Therefore, language intervention training and communication skills have been made a cornerstone of autism intervention. However, a literature search has revealed that most studies only examine certain intervention methods or a combination of two or three intervention methods, which cannot be used by therapists or rehabilitation teachers. Therefore, this article summarizes relevant literature on language communication training for ASD children at home and abroad and briefly introduces the characteristics and training methods of language disorders in children with ASD in order to provide some ideas and references for relevant researchers and practitioners.

Efficacy of very early interventions on neurodevelopmental outcomes for infants and toddlers at increased likelihood of or diagnosed with autism: A systematic review and meta-analysis

The aim of this systematic review was to determine the efficacy of very early interventions for infants and toddlers at increased likelihood of or diagnosed with autism for autism symptomatology, developmental outcomes and/or neurocognitive markers. Eight databases were searched (14 April 2022) with inclusion criteria: (i) RCTs with care as usual (CAU) comparison group, (ii) participants at increased likelihood of or diagnosed with autism and aged <24 months corrected age (CA), (iii) parent-mediated and/or clinician directed interventions, and (iv) outcome measures were autism symptomatology, cognition, language, adaptive skills, or neurocognitive assessments (EEG and eye tracking). Quality was assessed using Risk of Bias 2 and GRADE. Nineteen publications from 12 studies reported on 715 infants and toddlers. There was low to moderate certainty evidence that clinician-assessed outcomes did not show significant treatment effects for: autism symptomatology (ADOS CSS: MD -0.08, 95% CI -0.61, 0.44, p = 0.75), cognitive outcome (Mullen Scales of Early Learning-Early Learning Composite (MSEL-ELC): SMD 0.05, 95% CI -0.19, 0.29, p = 0.67), receptive language (MSEL-Receptive Language: SMD 0.04, 95% CI -0.21, 0.3, p = 0.74) or expressive language (MSEL-Expressive Language: SMD 0.06, 95% CI -0.1, 0.23, p = 0.45). Neurocognitive outcomes (EEG and eye tracking) were heterogeneous, with inconsistent findings. There is low to moderate certainty evidence that very early interventions have limited impact on neurodevelopmental outcomes by age 3 years.

Reexamining Pathways Early Autism Intervention in Children Before and After the Third Birthday: A Randomized Control Trial

We reexamined the efficacy of Pathways early autism intervention using generalized measures of social communication and language skills administered by an unfamiliar adult in a novel environment. Generalized measures improve on sources of measurement bias. Sixty-seven autistic children blocked on age (under versus over 3 years) were randomly assigned to 15 weeks of Pathways or services-as-usual. Age moderated the effects of Pathways for social communication. Specifically, Pathways had a significantly large effect for children under 3 and a small effect that approached significance for children over 3. Pathways also had a small effect on expressive speech/language skills. Results replicate previous findings of the efficacy of Pathways on proximal and distal skills and support the importance of early intervention.

Toddlers at Elevated Likelihood for Autism: Exploring Sensory and Language Treatment Predictors

Baseline child characteristics may predict treatment outcomes in children with or at elevated likelihood of developing autism (EL-ASD). Little is known about the role of child sensory and language features on treatment outcome. Participants were randomly assigned to a parent-mediated intervention or control condition. Analyses explored the relationship between baseline child sensory and language characteristics and changes in ASD symptoms over approximately 9 months. Higher baseline sensory hyporeactivity was significantly related to less improvement in social communication (SC) for the treatment group only. More baseline atypical vocalizations were significantly related to less improvement on SC across treatment and control groups. This work provides an initial framework to encourage the tailoring of interventions for EL-ASD children, suggesting sensory reactivity and atypical vocalizations may be useful behaviors to consider in treatment planning.

Developmental Screening Tools Used with First Nations Populations: A Systematic Review

Developmental surveillance and screening is recommended for all children under five years of age, especially for those from at-risk populations such as First Nations children. No review to date has, however, evaluated the use of developmental screening tools with First Nations children. This review aimed to examine and synthesise the literature on developmental screening tools developed for, or used with, First Nations populations children aged five years or younger. A PRISMA-compliant systematic review was performed in the PsychInfo, PubMed, and Embase databases. Additional searches were also undertaken. In total 444 articles were identified and 13 were included in the final review. Findings indicated that several developmental screening tools have been administered with First Nations children. Most tools, however, have only been evaluated in one study. Results also found that no studies evaluated actions taken following positive screening results. More research evaluating the accuracy, acceptability, and feasibility of using developmental screeners with First Nations children is required before widespread implementation of developmental screening in clinical settings with First Nations children is recommended.

Early intervention for very young children with or at high likelihood for autism spectrum disorder: An overview of reviews

AIM

To identify which interventions are supported by evidence and the quality of that evidence in very young children with or at high likelihood for autism spectrum disorder (ASD) to improve child outcomes.

METHOD

We conducted an overview of reviews to synthesize early intervention literature for very young children with or at high likelihood for ASD. Cochrane guidance on how to perform overviews of reviews was followed. Comprehensive searches of databases were conducted for systematic reviews and meta-analyses between January 2009 and December 2020. Review data were extracted and summarized and methodological quality was assessed. Primary randomized controlled trial evidence was summarized and risk of bias assessed. This overview of reviews was not registered.

RESULTS

From 762 records, 78 full texts were reviewed and seven systematic reviews and meta-analyses with 63 unique studies were identified. Several interventional approaches (naturalistic developmental behavioral intervention, and developmental and behavioral interventions) improved child developmental outcomes. Heterogeneity in design, intervention and control group, dose, delivery agent, and measurement approach was noted. Inconsistent methodological quality and potential biases were identified.

INTERPRETATION

While many early interventional approaches have an impact on child outcomes, study heterogeneity and quality had an impact on our ability to draw firm conclusions regarding which treatments are most effective. Advances in trial methodology and design, and increasing attention to mitigating measurement bias, will advance the quality of the ASD early intervention evidence base.

WHAT THIS PAPER ADDS

Naturalistic developmental behavioral interventions, as well as developmental and behavioral interventions, improve child outcomes in autism spectrum disorder (ASD). If only randomized controlled trials are considered, guidelines for early intensive behavioral intervention in younger children should be revisited. The greatest intervention impacts were on proximal, intervention-specific outcomes. Inadequacies in the quality of the early ASD intervention evidence base were observed.

Effectiveness of the SCERTS Model-Based Interventions for Autistic Children: A Systematic Review

PURPOSE

This systematic review aimed to examine the effectiveness of the Social Communication, Emotional Regulation, and Transactional Support (SCERTS) Model-based interventions in supporting developmental skills of children who were diagnosed with or at increased likelihood of autism.

METHOD

We searched six electronic databases, in addition to Google Scholar and the reference lists, using terms related to SCERTS, the Early Social Interaction project, and autism spectrum disorder. Of the 70 articles, six published between 2014 and 2021 (a total of 455 children) were eligible for inclusion and were analyzed in terms of study design, type of publication, participant characteristics, intervention procedures, and major findings.

RESULTS

Most reviewed studies that were relatively less vulnerable to the given risk of bias suggested that SCERTS may be an effective approach for promoting children's social communication skills, and implementers were able to achieve an adequate level of intervention fidelity through training. Further implications could not be drawn concerning children's language, reduction in restricted repetitive behaviors, emotional regulation, adaptive behavior, play, cognitive skills, academic competence, and motor skills due to contradicting findings within limited evidence.

CONCLUSIONS

Although SCERTS is a promising intervention with emerging evidence, more methodologically rigorous studies are needed to progress the research base of SCERTS and draw firm conclusions about its effectiveness in improving a wide range of skills for children and implementers. Several areas for future research are discussed.

An integrated early care pathway for autism

In this Viewpoint, we argue for the need to reconceptualise an integrated early-care provision for autistic children in the light of their enduring support needs and relevant new findings from developmental and intervention research. This model goes beyond short-term reactive care to outline an early proactive, evidenced, developmentally phased, and scalable programme of support for autistic children and their families from the earliest opportunity, with timely access to later step-up care when needed. We also integrate this model with emerging opportunities from data science and digital health technologies as a potential facilitator of such a pathway. Building on this work, we argue that the best current autism intervention evidence can be integrated with concepts and evidence gained in the management of other enduring health conditions to support an autistic child and their family through their early development. The aim is to improve those children's social communication abilities, expand their range and flexibility of interests, and mitigate any negative impacts of sensory difficulties and restricted, repetitive behaviours on the child and their family wellbeing. The pathway solutions described could also be adapted for older adolescents and adults and could be used within the health systems of different countries, including within low-income and middle-income contexts.

Combined social communication therapy at home and in education for young autistic children in England (PACT-G): a parallel, single-blind, randomised controlled trial

BACKGROUND

Autistic children can have difficulty generalising treatment effects beyond the immediate treatment context. Paediatric Autism Communication Therapy (PACT) has been successful when delivered in the clinic. Here we tested the Paediatric Autism Communication Therapy-Generalised (PACT-G) intervention combined between home and education settings for its overall effect and mechanistic transmission of effect across contexts.

METHODS

In this parallel, single-blind, randomised, controlled trial, we recruited autistic children aged 2-11 years in urban or semi-urban areas in Manchester, Newcastle, and London, England. Children needed to meet core autism criteria on Autism Diagnostic Observation Schedule-second edition (ADOS-2) and parent-rated Social Communication Questionnaire (SCQ-lifetime), and children older than 5 years were included if they had intentional communication but expressive language equivalent of age 4 years or younger. Eligible children were randomly assigned (1:1), using block randomisation (random block sizes of 2 and 4) and stratified for site, age (2-4 years vs 5-11 years), and gender, to either PACT-G plus treatment as usual or treatment as usual alone. Research assessors were masked to treatment allocation. The PACT-G intervention was delivered by a therapist in parallel to the child's parents at home and to learning-support assistants (LSA) at their place of education, using both in-person and remote sessions over a 6 month period, to optimise adult-child social interaction. Treatment as usual included any health support or intervention from education or local community services. The primary outcome was autism symptom severity using the ADOS-2, as measured by researchers, at 12 months versus baseline. Secondary outcomes were Brief Observation of Social Communication Change (BOSCC) and dyadic social interaction between child and adult across contexts, both at 12 months. Other secondary outcome measures were assessed using the following composites: language, anxiety, repetitive behaviour, adaptive behaviour, parental wellbeing, child health-related quality of life, and disruptive behaviour. Assessments were done at baseline, 7 months, and 12 months. We used an intention-to-treat (ITT) analysis of covariance for the efficacy outcome measures. Adverse events were assessed by researchers for all trial families at each contact and by therapists in the PACT-G group at each visit. This study is registered with the ISRCTN Registry, ISRCTN 25378536.

FINDINGS

Between Jan 18, 2017, and April 19, 2018, 555 children were referred and 249 were eligible, agreed to participate, and were randomly assigned to either PACT-G (n=122) or treatment as usual (n=127). One child in the PACT-G group withdrew and requested their data be removed from the study, giving an ITT population of 248 children. 51 (21%) of 248 children were female, 197 (79%) were male, 149 (60%) were White, and the mean age was 4·0 years (SD 0·6). The groups were well balanced for demographic and clinical characteristics. In the PACT-G group, parents of children received a median of 10 (IQR 8-12) home sessions and LSAs received a median of 8 (IQR 5-10) education sessions over 6 months. We found no treatment effect on the ADOS-2 primary outcome compared with treatment as usual (effect size 0·04 [95% CI -0·19 to 0·26]; p=0·74), or researcher-assessed BOSCC (0·03 [-0·25 to 0·31]), language composite (-0·03 [-0·15 to 0·10]), repetitive behaviour composite (0·00 [-0·35 to 0·35]), adaptive behaviour composite (0·01 [-0·15 to 0·18]), or child wellbeing (0·09 [-0·15 to 0·34]). PACT-G treatment improved synchronous response in both parent (0·50 [0·36 to 0·65]) and LSA (0·33 [0·16 to 0·50]), mediating increased child communication with parent (0·26 [0·12 to 0·40]) and LSA (0·20 [0·06 to 0·34]). Child dyadic communication change mediated outcome symptom alteration on BOSCC at home (indirect effect -0·78 [SE 0·34; 95% CI -1·44 to -0·11]; p=0·022) although not in education (indirect effect -0·67 [SE 0·37; 95% CI -1·40 to 0·06]; p=0·073); such an effect was not seen on ADOS-2. Treatment with PACT-G also improved the parental wellbeing composite (0·44 [0·08 to 0·79]) and the child disruptive behaviour composite in home and education (0·29 [0·01 to 0·57]). Adverse events on child behaviour and wellbeing were recorded in 13 (10%) of 127 children in the treatment as usual group (of whom four [31%] were girls) and 11 (9%) of 122 in the PACT-G group (of whom three [33%] were girls). One serious adverse event on parental mental health was recorded in the PACT-G group and was possibly study related.

INTERPRETATION

Although we found no effect on the primary outcome compared with treatment as usual, adaptation of the 12-month PACT intervention into briefer multicomponent delivery across home and education preserved the positive proximal outcomes, although smaller in effect size, and the original pattern of treatment mediation seen in clinic-delivered therapy, as well as improving parental wellbeing and child disruptive behaviours across home and school. Reasons for this reduced efficacy might be the reduced dose of each component, the effect of remote delivery, and the challenges of the delivery contexts. Caution is needed in assuming that changing delivery methods and context will preserve an original intervention efficacy for autistic children.

Rethinking Autism Intervention Science: A Dynamic Perspective

Recent advances in longitudinal methodologies for observational studies have contributed to a better understanding of Autism as a neurodevelopmental condition characterized by within-person and between-person variability over time across behavioral domains. However, this finer-grained approach to the study of developmental variability has yet to be applied to Autism intervention science. The widely adopted experimental designs in the field-randomized control trials and quasi-experimental designs-hold value for inferring treatment effects; at the same time, they are limited in elucidating what works for whom, why, and when, given the idiosyncrasies of neurodevelopmental disorders where predictors and outcomes are often dynamic in nature. This perspective paper aims to serve as a primer for Autism intervention scientists to rethink the way we approach predictors of treatment response and treatment-related change using a dynamic lens. We discuss several empirical gaps, and potential methodological challenges and opportunities pertaining to: (1) capturing finer-grained treatment effects in specific behavioral domains as indexed by micro-level within-person changes during and beyond intervention; and (2) examining and modeling dynamic prediction of treatment response. Addressing these issues can contribute to enhanced study designs and methodologies that generate evidence to inform the development of more personalized interventions and stepped care approaches for individuals on the heterogeneous spectrum of Autism with changing needs across development.

Caregiver responsiveness as a mechanism to improve social communication in toddlers: Secondary analysis of a randomized controlled trial

Early intensive behavioral interventions (EIBI) for children at elevated likelihood for a later diagnosis of autism spectrum disorder (EL-ASD), are often delivered through parent-mediated models. An area of current exploration is whether changes in caregiver behaviors are a mechanism through which to improve and track child behaviors in these interventions. Toddlers and their caregivers participated in an intervention trial (randomized controlled trial) and were randomized to either a parent-mediated intervention (adapted responsive teaching; ART) or a control condition (referral to early intervention and monitoring; REIM). Changes in toddler social communication (SC) behaviors and characteristics of caregiver responsiveness (CR) were quantified over 8 months. Analyses were conducted to assess whether changes in CR mediated the relation between group (ART vs. REIM) and changes in child SC. Results of the current study indicated that caregivers who participated in a parent-mediated intervention improved in three domains of CR (contingent verbal sensitivity, responsivity, affect). CR was also found to be a mechanism through which children's SC skills improved. This work provides evidence that qualities of CR serve as mechanisms through which to improve and monitor child behaviors over the course of EIBIs. These results may lead to novel intervention targets, methods for tracking change, and tailored treatment planning for toddlers with EL-ASD. The data used in this study comes from a clinical trial that was prospectively registered with the Registry of Efficacy and Effectiveness Studies (Registry ID: 316.1v1). LAY SUMMARY: Interventions for toddlers with high likelihood for a later diagnosis of autism often include the caregiver as an active participant in the intervention. In this study, we aimed to understand qualities of caregiver responsiveness (CR) that facilitate improvements in child behaviors during intervention. Results show that increasing verbal CR and affect are ways to improve child social skills over the course of intervention.

Efficacy of psychosocial interventions for Autism spectrum disorder: an umbrella review

INTRODUCTION

The wide range of psychosocial interventions designed to assist people with Autism Spectrum Disorder (ASD) makes it challenging to compile and hierarchize the scientific evidence that supports the efficacy of these interventions. Thus, we performed an umbrella review of published meta-analyses of controlled clinical trials that investigated the efficacy of psychosocial interventions on both core and related ASD symptoms.

METHODS

Each meta-analysis that was identified was re-estimated using a random-effects model with a restricted maximum likelihood estimator. The methodological quality of included meta-analyses was critically appraised and the credibility of the evidence was assessed algorithmically according to criteria adapted for the purpose of this study.

RESULTS

We identified a total of 128 meta-analyses derived from 44 reports. More than half of the non-overlapping meta-analyses were nominally statistically significant and/or displayed a moderate-to-large pooled effect size that favored the psychosocial interventions. The assessment of the credibility of evidence pointed out that the efficacy of early intensive behavioral interventions, developmental interventions, naturalistic developmental behavioral interventions, and parent-mediated interventions was supported by suggestive evidence on at least one outcome in preschool children. Possible outcomes included social communication deficits, global cognitive abilities, and adaptive behaviors. Results also revealed highly suggestive indications that parent-mediated interventions improved disruptive behaviors in early school-aged children. The efficacy of social skills groups was supported by suggestive evidence for improving social communication deficits and overall ASD symptoms in school-aged children and adolescents. Only four meta-analyses had a statistically significant pooled effect size in a sensitivity analysis restricted to randomized controlled trials at low risk of detection bias.

DISCUSSION

This umbrella review confirmed that several psychosocial interventions show promise for improving symptoms related to ASD at different stages of life. However, additional well-designed randomized controlled trials are still required to produce a clearer picture of the efficacy of these interventions. To facilitate the dissemination of scientific knowledge about psychosocial interventions for individuals with ASD, we built an open-access and interactive website that shares the information collected and the results generated during this umbrella review.

Pilot Randomized Controlled Trial of the WHO Caregiver Skills Training in Public Health Services in Italy

Parents of children with ASD (N = 86; mean age 44.8 months; 67 boys) were randomized to either WHO Caregiver Skills Training (CST) delivered in public health settings in Italy or enhanced treatment-as-usual. Primary blinded outcomes were 3-months post-intervention change scores of autism severity and engagement during caregiver-child interaction. CST was highly acceptable to caregivers and feasibly delivered by trained local clinicians. Intention-to-treat analysis showed a large and significant effect on parent skills supporting joint engagement and a smaller significant effect on flow of interaction. Expected changes in child autism severity and joint engagement did not meet statistical significance. Analysis of secondary outcomes showed a significant effect on parenting stress, self-efficacy, and child gestures. Strategies to improve the effectiveness of CST are discussed.

An evidence-based framework for determining the optimal amount of intervention for autistic children

The provision of timely, effective, and socially valid non-pharmacological intervention is at the core of efforts to support the development of young autistic children. These efforts are intended to support children to develop skills, empower their caregivers, and lay the foundation for optimal choice, independence, and quality of life into adulthood. But what is the optimal amount of intervention? In this Viewpoint, we review current guidelines and consider evidence from an umbrella review of non-pharmacological interventions for autistic children aged up to 12 years. We show the lack of consensus on the issue, identify factors that might be relevant to consider, and present an evidence-based framework for determining the optimal amount of intervention for each child, along with recommendations for future research.

Pre-symptomatic intervention for autism spectrum disorder (ASD): defining a research agenda

Autism spectrum disorder (ASD) impacts an individual's ability to socialize, communicate, and interact with, and adapt to, the environment. Over the last two decades, research has focused on early identification of ASD with significant progress being made in understanding the early behavioral and biological markers that precede a diagnosis, providing a catalyst for pre-symptomatic identification and intervention. Evidence from preclinical trials suggest that intervention prior to the onset of ASD symptoms may yield more improved developmental outcomes, and clinical studies suggest that the earlier intervention is administered, the better the outcomes. This article brings together a multidisciplinary group of experts to develop a conceptual framework for behavioral intervention, during the pre-symptomatic period prior to the consolidation of symptoms into diagnosis, in infants at very-high-likelihood for developing ASD (VHL-ASD). The overarching goals of this paper are to promote the development of new intervention approaches, empirical research, and policy efforts aimed at VHL-ASD infants during the pre-symptomatic period (i.e., prior to the consolidation of the defining features of ASD).

Keeping up with the evidence base: Survey of behavior professionals about Naturalistic Developmental Behavioral Interventions

LAY ABSTRACT

Primary service providers for young children on the autism spectrum and developmentally delayed children use many strategies under the umbrella of applied behavior analysis therapy. The evidence supporting interventions for children on the autism spectrum has changed last decade, and powerful research supports the relative effectiveness of Naturalistic Developmental Behavior Interventions, yet a few professionals serving young children on the autism spectrum receive training in this category of interventions. Board Certified Behavior Analysts and related professionals are the primary service providers for this population. The purpose of this survey study is to describe and understand the knowledge and beliefs that Behavior Analyst Certification Board certificants have around Naturalistic Developmental Behavior Interventions. The survey was completed by 901 respondents. Respondents indicated, on average, little to no knowledge of Naturalistic Developmental Behavior Intervention practices and few believe that these practices are effective or appropriate for the field. Recommendations include increasing training opportunities for related professionals, and changing certification requirements to match the current evidence.

School-Implemented Interventions for Preschool to High School Students with Autism: An Update on Recent Research

PURPOSE OF REVIEW

The purpose of this review is to provide an update on the recent research (2016-2021) that evaluates the effectiveness of school-implemented interventions for students with autism (3-21 years old) from preschool to high school.

RECENT FINDINGS

Overall, the recent literature demonstrated that there are EBPs that help students with autism acquire a variety of skills across domains (academic, social communication). Though many educators and peers were able to achieve high-fidelity implementation, there remains variable fidelity of intervention use in some studies. Though there is some evidence that educators and peers can successfully implement interventions, there are additional focal areas that are missing from the literature that are needed in schools (e.g., mental health, vocational). Future research should leverage implementation science approaches to support the use of proven efficacious interventions in schools.

Preliminary Evaluation of the FETASS Training for Parents of Children With Autism Spectrum Disorder: A Pilot Study

While several recent evaluation studies have shown the efficacy of parent training programs for children with neurodevelopmental disorders, manual-based training in German is still scarce. To address this gap, we developed a specific modularized training program for parents of children from preschool to pre-adolescent age with Autism Spectrum Disorder (FETASS). The overarching purpose of the FETASS intervention is to enhance social communication behavior and quality of life of the child by coaching parents. As a proximal target, the FETASS training aims to provide families with behavior management and communication strategies. The development of the training was influenced by published behavioral parent trainings and autism-specific interventions. The training comprises eight weekly sessions and targets families whose children have a diagnosis of Autism Spectrum Disorder (ASD) without intellectual and language impairments. As a preliminary pilot study, the purpose was to evaluate the acceptability of the training. Furthermore, the study aimed at initially evaluating social communication behavior, quality of life of the child, parental stress level, and parenting after training in comparison to a treatment as usual (TAU) group. Exploratively, long-term effects were investigated after 6 months of training as well. In total, 57 families participated (n[TAU] = 29, n[FETASS] = 28). Questionnaires about social communication behavior and quality of life of the child, parental stress, and parenting were administered at three time points (t1: baseline TAU/FETASS, t2: post TAU/FETASS; and t3: 6-month follow-up after FETASS). Primary outcome measures were the social communication behavior of the child and the parent's proxy report on quality of life of the child. Secondary outcome measures were changes in parental stress and parenting behavior. Acceptability of the training was very high and we had almost no dropouts during training. Results for the primary outcome measure of social communication behavior, overall quality of life of the child, and long-term effects on social communication behavior were not significant. While long-term findings for parent stress reduction and for the quality of life of the child are promising, further research has to be done in a future randomized controlled trial.
