Brief Report: Response to Joint Attention and Object Imitation as Predictors of Expressive and Receptive Language Growth Rate in Young Children on the Autism Spectrum

Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of expressive and receptive communication growth rate in a heterogeneous sample of autistic children. Children's baseline skills in responding to joint attention uniquely predicted expressive, but not receptive, language growth rate over time, while object imitation did not significantly predict language growth rate over and above joint attention skills. Future research should examine the potential moderating roles of child age and developmental level in explaining associations between joint attention and object imitation and later language development.

Relative Efficacy of Self-directed and Therapist-assisted Telehealth Models of a Parent-mediated Intervention for Autism: Examining Effects on Parent Intervention Fidelity, Well-being, and Program Engagement

PURPOSE

Although there is growing interest in telehealth to deliver parent-mediated intervention for autistic children, empirical evaluations are limited, and little is known regarding the relative benefits of self-directed and therapist-assisted telehealth interventions. This study examined the effect of self-directed and therapist-assisted ImPACT Online on parent learning and well-being, moderators of treatment, and predictors of program engagement.

METHOD

Sixty-four young autistic children and their primary caregiver participated. Children were matched on age and developmental quotient and randomly assigned to a therapist-assisted, self-directed, or resource support control group. Participants were assessed at intake, after 6 months (post), and at a 3-month follow-up.

RESULTS

There was a significant treatment effect for parent learning for the therapist-assisted but not self-directed program; when analysis was limited to parents who completed the program, treatment effects were observed for both groups. There were no treatment effects for parent self-efficacy or parenting stress; however, there was an effect on parents' perception of their child's positive impact. Parenting stress did not moderate the effect of group on parent outcomes. Parent age, program satisfaction, and therapist assistance were all significant predictors of parent program engagement.

CONCLUSION

This study supports the efficacy of therapist-assisted telehealth parent-mediated intervention for teaching parents intervention strategies to support their child's social communication and improving their perceptions of their child's positive impact, and suggests that self-directed programs may be beneficial for parents who fully engage with the program.

A mixed-methods examination of clinicians' perceived barriers to telehealth delivered applied behavior analysis

Following the COVID-19 pandemic, clinicians relied on telehealth to ensure continuity of essential healthcare services, such as Applied Behavior Analysis (ABA). Identifying barriers and examining them in the context of other implementation outcomes is important to support appropriate adaptations and sustainability of telehealth-delivered ABA services. Convergent mixed methods design was utilized to identify barriers experienced by ABA clinicians (N = 388) when delivering ABA services over telehealth to autistic children and their families following the first six months of the COVID-19 pandemic. Additionally, barriers were examined in relation to telehealth implementation outcomes and intentions for continued adoption. Findings reveal that clinicians rated providing direct services (M = 3.52, SD = 1.14) as more difficult than conducting assessments (M = 3.29, SD = 1.06), and both as more difficult than providing parent-mediated interventions [(M = 2.47, SD = 1.11), F(2, 381) = 162.26, p < 0.001]. A principal components analysis indicated a 3-factor solution of barriers related to: (1) technology (α = 0.82), (2) administrative tasks (α = 0.88), and (3) client characteristics (α = 0.88). The most frequently endorsed barriers were related to client characteristics, including increased difficulty providing telehealth services to children who elope (M = 4.37, SD = 0.81), children who exhibit challenging behaviors (M = 4.31; SD = 0.83), and children who are in the preverbal stage or use nonverbal language to communicate (M = 4.07; SD = 1.00). Fewer barriers related to client characteristics uniquely predicted implementation variables including acceptability, appropriateness, and feasibility. Thematic analysis revealed challenges related to technology, caregiver involvement, child engagement, implementation of intervention strategies over telehealth, and administrative or logistical barriers. These findings highlight the need for targeted strategies that facilitate telehealth use to address specific client needs and support the implementation of telehealth services in usual care settings.

Programmatic Costs of Project ImPACT for Children with Autism: A Time-Driven Activity Based Costing Study

Programmatic cost assessment of clinical interventions can inform future dissemination and implementation efforts. We conducted a randomized trial of Project ImPACT (Improving Parents As Communication Teachers) in which community early intervention (EI) providers coached caregivers in techniques to improve young children's social communication skills. We estimated implementation and intervention costs while demonstrating an application of Time-Driven Activity-Based Costing (TDABC). We defined Project ImPACT implementation and intervention as processes that can be broken down successively into a set of procedures. We created process maps for both implementation and intervention delivery. We determined resource use and costs, per unit procedure in the first year of the program, from a payer perspective. We estimated total implementation cost per clinician and per site, intervention cost per child, and provided estimates of total hours spent and associated costs for implementation strategies, intervention activities and their detailed procedures. Total implementation cost was $43,509 per clinic and $14,503 per clinician. Clinician time (60%) and coach time (12%) were the most expensive personnel resources. Implementation coordination and monitoring (47%), ongoing consultation (26%) and clinician training (19%) comprised most of the implementation cost, followed by fidelity assessment (7%), and stakeholder engagement (1%). Per-child intervention costs were $2619 and $9650, respectively, at a dose of one hour per week and four hours per week Project ImPACT. Clinician and clinic leader time accounted for 98% of per child intervention costs. Highest cost intervention activity was ImPACT delivery to parents (89%) followed by assessment for child's ImPACT eligibility (10%). The findings can be used to inform funding and policy decision-making to enhance early intervention options for young children with autism. Uncompensated time costs of clinicians are large which raises practical and ethical concerns and should be considered in planning of implementation initiatives. In program budgeting, decisionmakers should anticipate resource needs for coordination and monitoring activities. TDABC may encourage researchers to assess costs more systematically, relying on process mapping and gathering prospective data on resource use and costs concurrently with their collection of other trial data.

Factors that influence clinical decisions about offering parent coaching for autistic youth served within the Medicaid system

Background

Parent coaching is an evidence-based practice for young autistic children, but it is underutilized in lower-resourced community settings like the Medicaid system (Straiton et al., 2021b). Clinicians often struggle to implement parent coaching with low-income and marginalized families (Tomczuk et al., 2022), but little is known about which factors influence clinician decision making processes about providing parent coaching to this population.

Methods

This qualitative analysis used the framework method and thematic analysis. We used the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework (Aarons et al., 2011) to identify factors in the clinical decision-making process that community providers use when offering parent coaching to families of Medicaid-enrolled autistic children. Interviews with 13 providers and a focus group with 13 providers were analyzed.

Results

The following themes emerged: 1) Policies drive provider task priorities and affect competing demands; 2) Providers are more likely to use parent coaching when agency leaders monitor parent coaching benchmarks, though this is rarely done; 3) Logistical factors like scheduling and treatment location affect perceived feasibility of using parent coaching; 4) Previous experience or coursework in parent coaching and/or family systems supports the quality of parent coaching implementation; 5) Provider perceptions of "parent readiness" are initially indicated by overt expressions of parent interest.

Conclusions

In the absence of outer-context and inner-context policies, providers have more decision-making power to offer parent coaching based on their own judgements and preferences, which may result in fewer families being offered parent coaching and increased bias related to which families are offered this service. State-, agency-, and clinician-level recommendations are provided for increasing equitable provision of this evidence-based practice for autism.

Revisiting the simplification of adult language input in the context of naturalistic developmental behavioral interventions: A commentary

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.

A method for defining the CORE of a psychosocial intervention to guide adaptation in practice: Reciprocal imitation teaching as a case example

LAY ABSTRACT

Interventions that support social communication include several "components," or parts (e.g. strategies for working with children and families, targeting specific skills). Some of these components may be essential for the intervention to work, while others may be recommended or viewed as helpful but not necessary for the intervention to work. "Recommended" components are often described as "adaptable" because they can be changed to improve fit in different settings where interventions are offered or with different individuals. We need to understand which parts of an intervention are essential (and which are adaptable) when translating interventions from research to community settings, but it is challenging to do this before studying an intervention in the community. This article presents the CORE (COmponents & Rationales for Effectiveness) Fidelity Method-a new method for defining the essential components of evidence-based interventions-and applies it to a case example of Reciprocal Imitation Teaching, an intervention that parents are taught to deliver with their young children with social communication delays. The CORE Fidelity Method involves three steps: (1) gathering information from multiple sources; (2) integrating information from previous research and theory; and (3) drafting a CORE model for ongoing use. The benefits of using the CORE Fidelity Method may include: (1) improving consistency in intervention and research materials to help all providers emphasize the most important skills or strategies; (2) clarifying which parts of the intervention can be adapted; and (3) supporting future research that evaluates which intervention components work and how they work.

Using qualitative content analysis to understand the active ingredients of a parent-mediated naturalistic developmental behavioral intervention

LAY ABSTRACT

Although naturalistic developmental behavioral interventions are supported by research for supporting the development of children on the autism spectrum, how they work is not well understood. This study reviewed parent reflection comments in a systematic way to better how one such treatment worked, when delivered by caregivers. Caregivers completed weekly written reflection responses as they learned how to use the treatment techniques. We studied these responses to understand caregiver perspectives on how their children responded to the techniques. The responses were then compared to a theory of how the treatment works. Many responses were consistent with the treatment theory; however, others were not. We found that individual techniques were associated with different child responses, suggesting that general measures of social communication may not measure these specific short-term changes. Our findings point to specific behaviors that may be useful to measure in future research, or useful as indicators of treatment response in clinical practice settings. Overall, qualitative methods may be useful for understanding complex treatment processes.

Age differences in broader autism phenotype traits from young adulthood to older adulthood

Much of past research has been dedicated to refining the operationalization and correlates of the broader autism phenotype (BAP) and less on how the BAP differs by socio-demographic characteristics, like age-particularly after midlife. This gap is important because other nonclinical trait-like characteristics (e.g., personality) have shown considerable age differences, leading to work assessing the malleability of psychological characteristics and improving outcomes for individuals and their significant others. In the current study, we examined cross-sectional age differences in the BAP in a large sample of adults ranging in age from 18 to 85. We recruited a sample of 2966 adults ranging in age from 18 to 85 (M_age = 36.53, SD = 12.61; 58.9% Female; 1.1% with an ASD diagnosis) recruited from an online survey service. We found that total BAP scores were higher in younger adults and lower among older adults. These differences were particularly true for pragmatic language difficulties, with this component of the BAP showing the most dramatic age differences. Aloofness showed similar negative associations with age, albeit much smaller. Rigidity was not significantly associated with age. The results are consistent with other research showing an abatement of symptoms among individuals with autism spectrum disorders (ASDs) across early life and theories predicting changes in other psychological characteristics (e.g., personality). The results are discussed in the context of the malleability of ASD and BAP traits across life, the clinical implications of these changes, and the origins and consequences for lifespan differences in BAP. LAY SUMMARY: Little is known about how subclinical autistic-like traits among middle-aged and older adults compare to younger adults. We found that these subclinical traits were highest in young adults and lowest in older adults. Knowing how these traits differ by age can provide researchers and clinicians with a sense of how much these traits might change across life, if the traits might be sensitive to interventions, and when in development it might be best to intervene.

A mixed methods exploration of community providers' perceived barriers and facilitators to the use of parent training with Medicaid-enrolled clients with autism

LAY ABSTRACT

Using quantitative data from an online survey and qualitative data from follow-up interviews with applied behavior analysis providers, researchers examined barriers and facilitators to providing parent training to Medicaid-enrolled youth with autism spectrum disorder. Barriers and facilitators were identified at the family-, provider-, and organization-levels. Family-level barriers were significantly related to less frequent parent training use and poorer quality of use. Two recommendations are provided to increase the use of parent training in low-resourced community settings: (1) provide professional training opportunities to providers about best practices in parent training and (2) increase agency support for parent training, particularly in reducing logistical barriers.

Factors related to parental therapeutic self-efficacy in a parent-mediated intervention for children with autism spectrum disorder: A mixed methods study

LAY ABSTRACT

Parental self-efficacy refers to parents' beliefs in their ability to successfully parent their child. Parental self-efficacy plays an important role in family outcomes when a child has autism spectrum disorder. It is important to consider therapeutic self-efficacy, one's feelings of self-efficacy regarding their implementation of an intervention, within parent-mediated interventions. The goal of this mixed methods study was to better understand factors that relate to parents' therapeutic self-efficacy when using a telehealth-based parent-mediated intervention. Participants were 51 parents of children with autism spectrum disorder between 17 and 83 months old. Parents had generally high therapeutic self-efficacy, and global parental self-efficacy was significantly related therapeutic self-efficacy. Parents' written reflections revealed four themes that related to their therapeutic self-efficacy: the importance of a good fit between the child's skills and the intervention, the importance of a good fit between the parent's interaction style and the intervention, environmental factors support intervention use, and the importance of the child's response to the intervention. Several themes differed for parents with higher and lower therapeutic self-efficacy. Findings suggest that global parental self-efficacy plays an important role in parental therapeutic self-efficacy in parent-mediated interventions. To support parents in learning, coaches should ask about the child's skills, parent's interaction style, environmental challenges, and child's response.

Identifying and measuring the common elements of naturalistic developmental behavioral interventions for autism spectrum disorder: Development of the NDBI-Fi

LAY ABSTRACT

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

Parent Training for Youth with Autism Served in Community Settings: A Mixed-Methods Investigation Within a Community Mental Health System

Parent training programs focus on parent knowledge and/or skill development regarding strategies to improve child outcomes. Parent training programs are considered evidenced-based treatments for autism spectrum disorder (ASD). Yet little is known about parent training use for youth with ASD served in community settings. This mixed methods project examined parent training for Medicaid-enrolled youth with ASD under age 21. Data were obtained from Medicaid claims for 879 youth and surveys from 97 applied behavior analysis (ABA) providers. Open-ended survey items were analyzed with content analysis. Results demonstrated that the frequency of parent training was low and providers' conceptualization of parent training was inconsistent with evidence-based models. Providers are largely unaware of evidence-based components (i.e., modeling, caregiver practice with feedback) and use them infrequently. Implications for increasing parent training in community settings are discussed.

The Role of Professional Training Experiences and Manualized Programs in ABA Providers' Use of Parent Training With Children With Autism

Parent training, in which providers teach parents intervention strategies to promote their children's skill acquisition and/or behavior management, is considered a best practice in the treatment for children with autism spectrum disorder (ASD) and yet is underutilized in community settings. The present study examined the role of training experiences and manual use in promoting the use of parent training by community providers who serve children with ASD. Applied behavior analysis (ABA) providers (N = 1,089) from across the United States completed self-report questionnaires online. The total number of professional training experiences related to parent training significantly predicted the extensiveness of providers' use of parent training. Receiving supervision in parent training, being trained in a specific parent training approach, taking a course related to parent training, and participating in self-guided learning (e.g., webinar) were unique predictors of parent training extensiveness. While only 15% of ABA providers used manualized parent training programs, using a manual was also a unique predictor of parent training extensiveness. Parallel multiple mediator analyses demonstrated that family-, provider-, and organization-level barriers all partially mediated the relationship between number of training experiences and parent training extensiveness; only provider- and organization-level barriers mediated the relationship between manual use and parent training extensiveness. Recommendations for training and supporting providers at the pre-service and in-service levels are discussed as a means of increasing access to parent training for children with ASD in community settings.

Service deserts and service oases: Utilizing geographic information systems to evaluate service availability for individuals with autism spectrum disorder

LAY ABSTRACT

Autism spectrum disorder and co-occurring symptoms often require lifelong services. However, access to autism spectrum disorder services is hindered by a lack of available autism spectrum disorder providers. We utilized geographic information systems methods to map autism spectrum disorder provider locations in Michigan. We hypothesized that (1) fewer providers would be located in less versus more populated areas; (2) neighborhoods with low versus high socioeconomic status would have fewer autism spectrum disorder providers; and (3) an interaction would be found between population and socioeconomic status such that neighborhoods with low socioeconomic status and high population would have few available autism spectrum disorder providers. We compiled a list of autism spectrum disorder providers in Michigan, geocoded the location of providers, and used network analysis to assess autism spectrum disorder service availability in relation to population distribution, socioeconomic disadvantage, urbanicity, and immobility. Individuals in rural neighborhoods had fewer available autism spectrum disorder providers than individuals in suburban and urban neighborhoods. In addition, neighborhoods with greater socioeconomic status disadvantage had fewer autism spectrum disorder providers available. Finally, wealthier suburbs had good provider availability while few providers were available in poorer, urban neighborhoods. Knowing autism spectrum disorder providers' availability, and neighborhoods that are particularly poorly serviced, presents the opportunity to utilize evidence-based dissemination and implementation strategies that promote increased autism spectrum disorder providers for underserved individuals.

The relationship between social experience and subjective well-being in autistic college students: A mixed methods study

This mixed methods study examined the relationship between the college social experience and subjective well-being in autistic students in the Midwestern United States. An online survey focused on social connectedness, social participation, social support, and subjective well-being. A semi-structured interview discussed transition, supports received, and social participation. Correlations and a hierarchical regression were used to examine the relationship between social experience variables and subjective well-being from the survey. Inductive thematic analysis was used to identify interview themes. Theme counts for students who reported higher and lower subjective well-being were examined. Social connectedness, time spent with friends, and perceived social support were positively correlated with students' subjective well-being, with social connectedness explaining unique variance. Common themes included challenges navigating a new social environment and the importance of family, friends, and professors in providing social support. Students with lower subjective well-being more frequently discussed struggles to make social connections and the trade-off between socializing and succeeding academically, whereas students with higher subjective well-being more frequently described college as providing opportunities to develop meaningful social connections. This study adds new perspectives on the college experience for autistic students and highlights the important role that social connections and support play in their subjective well-being.

Measuring child social communication across contexts: Similarities and differences across play and snack routines

Improving measurement of outcomes in randomized controlled trials of early interventions for autism spectrum disorder (ASD) has been identified as a priority in the field. In addition, the importance of measurement across contexts has been indicated by researchers and community stakeholders alike [Lord et al., ; McConachie et al., ; Schreibman et al., ]. The Brief Observation of Social Communication Change (BOSCC; Grzadzinski et al., ), an observational rating scheme of brief play interactions, was developed to address a need for measures that are reliable, sensitive to change, and valid for use in research settings. The goal of this study was to examine the feasibility and utility of applying the BOSCC to a new context: a home snack routine. Results suggest that rating the BOSCC on home snack routines is feasible and psychometrically sound, and captures change in child social communication behaviors. However, the utility of the BOSCC for measuring restricted and repetitive behaviors (RRBs) is less clear. Nonetheless, differences in RRBs across play and snack lend support for the claim that measurement across contexts is essential. Application of the BOSCC across contexts may allow researchers to obtain a more accurate estimate of intervention response and help capture context-specific changes in social communication. It may also provide a method for researchers to evaluate the effect of context on child social communication more broadly. Autism Res 2019, 12: 636-644. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Improving measurement of outcomes in studies of early interventions for autism spectrum disorder (ASD) has been identified as a priority in the field. The importance of measurement across contexts has also been indicated by researchers and community stakeholders. The goal of this study was to determine whether an existing observational rating scheme, the Brief Observation of Social Communication Change (BOSCC), could be applied to a new activity: a home snack routine. Results suggest that rating the BOSCC on home snack routines is feasible and promising for capturing change over time. In addition, some child behaviors differed across play and snack, lending further support for the claim that measurement across activities is essential.

Community providers' intentions to use a parent-mediated intervention for children with ASD following training: an application of the theory of planned behavior

Objectives

The theory of planned behavior (TPB) suggests that attitudes, subjective norms, and perceived behavioral control influence intentions to perform a behavior, and that intentions predict behavior. The present studies examined whether the TPB is applicable to community providers’ use of a parent-mediated intervention for children with autism spectrum disorder (ASD) following introductory training and whether TPB constructs can be modified with training.

Results

Study 1 demonstrated that community providers’ intentions to use the intervention post-training predicted their use of the intervention 6 months later [X²(1) = 8.03, p = .005]. Study 2 found that provider education (β = .23, t = 2.27, p = .025), attitudes (β = .21, t = 2.09, p = .039), and perceived behavioral control (β = .21, t = 2.15, p = .035) were all unique predictors of intentions. There was a significant increase in providers’ ratings of subjective norms (Z = − 2.46, p = .014) and perceived behavioral control (Z = − 7.36, p < .001) from pre- to post-training. Attitudes towards parent-mediated interventions were highly favorable pre-training and did not significantly increase. Results expand on previous findings and demonstrate the applicability of attitudes and perceived behavioral control in understanding community providers’ use of evidence-based practices for children with ASD.

Maternal cytomegalovirus sero-positivity and autism symptoms in children

PROBLEM

Autism spectrum disorder (ASD) is one of the most commonly diagnosed neurodevelopmental disorders in the United States. While ASD can be significantly influenced by genetics, prenatal exposure to maternal infections has also been implicated in conferring risk. Despite this, the effects of several important maternal pathogens, such as cytomegalovirus (CMV) and herpes simplex virus 2 (HSV2), remain unknown.

METHOD OF STUDY

We tested whether maternal CMV and/or HSV2 sero-positivity was associated with ASD symptoms in children. ELISA was used to assay for CMV IgG and HSV2 IgG in serum from the mothers of 82 children whose ASD symptoms were assessed at 3-6 years of age using the Social Responsiveness Scale version 2 (SRS-2).

RESULTS

Associations between maternal viral serostatus and SRS-2 scores were estimated using linear regression with covariate adjustments. The children of mothers sero-positive for CMV, but not for HSV2, had SRS-2 scores 3.6-4.2 points higher, depending on the adjustment model, than sero-negative women, a significant finding, robust to several statistical adjustments.

CONCLUSION

Our results suggest that maternal CMV infections may influence ASD symptoms. These findings are being further evaluated in ongoing prospective studies with larger population samples.

Understanding the impact of adaptations to a parent-mediated intervention on parents' ratings of perceived barriers, program attributes, and intent to use

Within the autism spectrum disorder field, rates of attrition in parent-mediated interventions have highlighted the need to engage families around improving the delivery of these services. The primary goal of this study was to approximate the impact of adaptations to an evidence-based, parent-mediated intervention, Project ImPACT (Improving Parents as Communication Teachers), that had been made in collaboration with families in a Medicaid system. A total of 103 parents of a child with autism spectrum disorder were randomized to watch a presentation of either the original or adapted Project ImPACT program. After watching the presentation, participants rated (1) demographic information, (2) perceived structural barriers, (3) Project ImPACT attributes, and (4) intent to use the program. Results from hierarchical linear regression models demonstrated that program type alone predicted parents' ratings of perceived structural barriers. Additionally, both program type and the interaction of program type and annual household income were unique predictors of parents' ratings of program attributes and intent to use. Qualitatively, although many parents reflected positively on both Project ImPACT programs, parents who viewed the adapted program appeared more likely to report positive program attributes. Results suggest the importance of engaging families in improving the fit of parent-mediated interventions for use within a variety of community settings.

Self-Directed Telehealth Parent-Mediated Intervention for Children With Autism Spectrum Disorder: Examination of the Potential Reach and Utilization in Community Settings

BACKGROUND

There is a significant need for strategies to increase access to evidence-based interventions for children with autism spectrum disorder (ASD). One novel approach is to train parents to use evidence-based interventions for their child with ASD via telehealth. Pilot work examining the efficacy of one such program, ImPACT Online, demonstrated a high rate of parent program engagement, low attrition, and associated gains in parent learning and child social communication.

OBJECTIVE

The objective of this study was to conduct an open trial of ImPACT Online to better understand its dissemination potential.

METHODS

We examined the reach and representativeness of families who registered (n=36) compared to families who were referred (n=139) to the open trial for one referral site. We then compared the demographics of all families who enrolled in the open trial (n=112) to families who enrolled in one of two controlled trials of the same program (n=50). We also examined metrics of program engagement for the open and controlled trials, the relationship between program engagement and changes in parents' intervention knowledge, and program evaluation for the participants in the open trial.

RESULTS

In total, 25.8% (36/139) of the parents who were given information about the program at their child's diagnostic feedback session registered with the program. The parents who enrolled in the open (OT) and controlled trials (CT), respectively, were similar in gender (OT: 84.8% (95/112); CT: 88% (44/50), female), marital status (OT: 80.4% (90/112) ; CT: 69.6% (32/46), married), education (OT: 58.0% (65/112); CT: 54.0% (27/50), college degree or higher), and employment status (OT: 58.0% (65/112); CT: 65.3% (32/49), employed outside the home). The child participants were similar in terms of gender (OT: 83.0% (93/112); CT: 76.0% (38/50), male) and race and ethnicity (OT: 38.4% (43/112); CT: 24.0% (12/50), minority). However, the mean chronological age of the child participants in the open trial group was significantly higher (Mean=60.0 months) than in the controlled trial group (Mean=43.0 months), with t₁₆₀=5.22, P<.001. Parents in the open trial engaged with the program at a significantly lower rate than the controlled trial, F_3,81=21.14, P<.001. Program engagement was significantly associated with gains in parent intervention knowledge across both the groups, beta=.41, t=2.43, P=.02. Participants in the open access trial evaluated the program highly, but several barriers were noted.

CONCLUSIONS

These data suggest that additional strategies may need to be developed to support families in using telehealth-based parent-mediated intervention in community settings.

Improving social functioning and challenging behaviors in adolescents with ASD and significant ID: A randomized pilot feasibility trial of reciprocal imitation training in a residential setting

There is a lack of effective social interventions for youths with ASD and co-morbid intellectual disability (ID). A previous single-case design study indicated that reciprocal imitation training (RIT) may improve social interaction and challenging behavior in this population. The current pilot study examined the feasibility of conducting an RCT to investigate the effectiveness of RIT for improving social functioning and challenging behaviors in 20 adolescents with ASD and severe ID in a residential program. The assessment protocol was feasible. RIT was well-tolerated by the adolescents and implemented with fidelity by teaching staff. Preliminary findings indicate that treatment had moderate to large effects on social functioning and challenging behavior, with mixed findings for imitation skills. A larger RCT of RIT for this population is feasible and warranted.

Behavioral Approaches to Promoting Play

A variety of techniques grounded in behavioral psychology, and more specifically in applied behavior analysis, have been established to increase and improve play skills in children with autistic spectrum disorders. This article introduces a set of efficacious methods, which range from highly structured techniques to more naturalistic strategies. It focuses on object play as other authors in the issue discuss social play in greater depth. Behavioral techniques that are reviewed include: discrete trial training, use of stereotyped behaviors to increase play skills, pivotal response training, reciprocal imitation training, differential reinforcement of appropriate behavior, in vivo modeling and play scripts, and video modeling. A discussion of expanding behavior techniques to teach more complex play as well as training in varied environments is also presented. References are provided to allow the reader to obtain more in-depth information about each technique.

Naturalistic Developmental Behavioral Interventions: Empirically Validated Treatments for Autism Spectrum Disorder

Earlier autism diagnosis, the importance of early intervention, and development of specific interventions for young children have contributed to the emergence of similar, empirically supported, autism interventions that represent the merging of applied behavioral and developmental sciences. “Naturalistic Developmental Behavioral Interventions (NDBI)” are implemented in natural settings, involve shared control between child and therapist, utilize natural contingencies, and use a variety of behavioral strategies to teach developmentally appropriate and prerequisite skills. We describe the development of NDBIs, their theoretical bases, empirical support, requisite characteristics, common features, and suggest future research needs. We wish to bring parsimony to a field that includes interventions with different names but common features thus improving understanding and choice-making among families, service providers and referring agencies.

Parent Engagement With a Telehealth-Based Parent-Mediated Intervention Program for Children With Autism Spectrum Disorders: Predictors of Program Use and Parent Outcomes

BACKGROUND

There has been growing interest in using telehealth to increase access to parent-mediated interventions for children with ASD. However, little is known about how parents engage with such programs.

OBJECTIVE

This paper presents program engagement data from a pilot study comparing self-directed and therapist-assisted versions of a novel telehealth-based parent-mediated intervention for young children with autism spectrum disorders (ASD).

METHODS

Parents of young children with ASD were randomly assigned to receive a self-directed or therapist-assisted version of ImPACT Online. Parent engagement and satisfaction with the different components of the program website were examined using the program's automated data collection and a post-treatment evaluation survey. We examined the relationship between program engagement and changes in parent knowledge and implementation and participant characteristics associated with program engagement.

RESULTS

Of the 27 parent participants, the majority were female (26/27, 96%), married (22/27, 81%), with a college degree or higher (18/27, 66%), and less than half were employed outside of the home (10/27, 37%). The mean chronological age of the child participants was 43.26 months, and the majority were male (19/27, 70%) and white (21/27, 78%). Most of the families (19/27, 70%) resided in a rural or medically underserved area. Parents logged into the website an average of 46.85 times, spent an average of 964.70 minutes on the site, and completed an average of 90.17% of the lesson learning activities. Participants in the therapist-assisted group were more likely to engage with the website than those in the self-directed group: F2,24=17.65, P<.001. In total, 85% of participants completed the program, with a significantly greater completion rate in the therapist-assisted group (N=27): χ(2) 1=5.06, P=.03. Lesson learning activities were visited significantly more often than the supplemental activities (all Ps<.05). Multiple regression controlling for pretreatment performance indicated that program completion (beta=.51, P=.02) predicted post-treatment intervention knowledge, and program completion (beta=.43, P=.03) and group assignment (beta=-.37, P=.045) predicted post-treatment intervention fidelity. Partial correlations indicated that parent depressive symptoms at pretreatment were negatively associated with program completion (r=-.40, P=.04), but other key parent and child demographic factors were not. Post-treatment measures of website usability (r=.65, P<.001), treatment acceptability (r=.58, P=.002), and overall satisfaction (r=.58, P=.002) were all related to program completion.

CONCLUSIONS

Parent engagement and satisfaction with ImPACT Online was high for both self-directed and therapist-assisted versions of the program, although therapist assistance increased engagement. Program completion was associated with parent outcomes, providing support for the role of the website in parent learning. This program has the potential to increase access to parent-mediated intervention for families of children with ASD.

A further investigation of goal-directed intention understanding in young children with autism spectrum disorders

Findings from research investigating goal-directed intention understanding in children with autism spectrum disorders (ASD) have been equivocal, in part because of the varying methodologies used across studies. This study compares both object-oriented and social-communicatively cued goal-directed intention understanding in children with ASD and typically-developing children. Relative to matched controls, children with ASD did not exhibit deficits in object-oriented intention understanding. While children with ASD also demonstrated the ability to understand intention when cued by social-communication indicators, typically-developing children differentiated between intentional and unintentional acts at a significantly greater level. Group differences in performance were eliminated if only trials in which children attended to the experimenter's face were considered. Results suggest that children with ASD have intact object-oriented intention understanding abilities, and are able to use social-communicative cues to understand intention. However, their ability to demonstrate social-communicatively cued intention understanding is limited by a lack of attention to relevant social-communicative information.

An Evaluation of Imitation Recognition Abilities in Typically Developing Children and Young Children with Autism Spectrum Disorder

Previous work has indicated that both typically developing children and children with Autism Spectrum Disorder (ASD) display a range of imitation recognition behaviors in response to a contingent adult imitator. However, it is unknown how the two groups perform comparatively on this construct. In this study, imitation recognition behaviors for children with ASD and typically developing children were observed during periods of contingent imitation imbedded in a naturalistic imitation task. Results from this study indicate that children with ASD are impaired in their ability to recognize being imitated relative to typically developing peers as demonstrated both by behaviors representing basic social attention and more mature imitation recognition. Display of imitation recognition behaviors was independent of length of contingent imitation period in typically developing children, but rate of engagement in imitation recognition behaviors was positively correlated with length of contingent imitation period in children with ASD. Exploratory findings also suggest a link between the ability to demonstrate recognition of being imitated and ASD symptom severity, language, and object imitation for young children with ASD.

Initial efficacy of project ImPACT: a parent-mediated social communication intervention for young children with ASD

Project ImPACT is a parent-mediated social communication intervention for young children with ASD that was developed in community settings to encourage dissemination. A single-subject, multiple-baseline design was conducted across 8 preschoolers with ASD and their mothers to examine the efficacy of the model for improving parent intervention fidelity and child spontaneous language. Multilevel modeling was used to examine the relationship between parent fidelity and child language within session. All parents increased their use of the intervention techniques. Improvements in spontaneous use of language targets were observed for 6 of the 8 children. There was a significant association between parents' use of the intervention strategies and their child's spontaneous language use.

Social intervention for adolescents with autism and significant intellectual disability: initial efficacy of reciprocal imitation training

Individuals with autism have difficulty with social skills across the lifespan. Few social interventions have been examined for older individuals with autism who also have significant intellectual disabilities (ID). Previous research suggests that reciprocal imitation training (RIT) improves imitation and social engagement in young children with autism. This study used a multiple-baseline design to examine whether RIT could improve social behaviors in four adolescents with autism and significant ID. All adolescents improved their spontaneous imitation and two improved their joint engagement. In addition, two adolescents decreased their rate of self-stimulatory behaviors over the course of treatment. Overall, these results suggest that RIT may be effective at improving social interaction and decreasing self-stimulatory behavior in adolescents with autism and significant ID.

An exploration of imitation recognition in young children with autism spectrum disorders

The ability to recognize when one is being imitated has been hypothesized to be an important developmental process related to the emergence of more advanced social-cognitive skills. While a series of behaviors indicating progressively more mature imitation recognition (IR) skills has been assessed in typically developing children, empirical work with children with autism spectrum disorders (ASDs) has largely focused on basic social responses to an imitative adult (e.g. increases in eye contact). Limited work has explored more mature IR behaviors in this population. This study compared the degree to which children with ASD engage in different behaviors thought to be indicative of IR during a naturalistic imitation task and the relationship between different types of IR behaviors and social-cognitive skills (i.e. imitation, language, social reciprocity, and joint attention). Thirty children with ASD were administered standardized measures of cognitive level, language, joint attention, social reciprocity, and imitation. IR behaviors were observed during periods of contingent imitation by an adult. Participants engaged more frequently in less mature (e.g. looking at the experimenter's toy or face) than more mature IR behaviors (e.g. testing the experimenter's intent to imitate). After controlling for developmental level, social reciprocity, object imitation, and gesture imitation were positively correlated with more mature IR. These findings suggest that the development of more mature IR skills is related to the development of other social-cognitive skills in children with ASD and provide additional empirical support for reports of more mature IR observed in this population. , Inc.

Brief report: effect of a focused imitation intervention on social functioning in children with autism

Imitation is an early skill thought to play a role in social development, leading some to suggest that teaching imitation to children with autism should lead to improvements in social functioning. This study used a randomized controlled trial to evaluate the effect of a focused imitation intervention on initiation of joint attention and social-emotional functioning in 27 young children with autism. Results indicated the treatment group made significantly more gains in joint attention initiations at post-treatment and follow-up and social-emotional functioning at follow-up than the control group. Although gains in social functioning were associated with treatment, a mediation analysis did not support imitation as the mechanism of action. These findings suggest the intervention improves social functioning in children with ASD.

A comparison of developmental social-pragmatic and naturalistic behavioral interventions on language use and social engagement in children with autism

PURPOSE

Developmental social-pragmatic and naturalistic behavioral interventions share a number of features, but they differ in their use of facilitative strategies and direct elicitation of child language. In this study, the authors investigated whether these approaches produce different language and social outcomes in young children with autism.

METHOD

The authors used an ABACAD design to compare the effects of a developmental social-pragmatic, naturalistic behavioral, and combined intervention on language type and function and social engagement in 5 children with autism.

RESULTS

Milieu teaching and the combined intervention produced higher rates of language targets than did responsive interaction. An analysis of the type and function of language targets suggested that differences between conditions were driven primarily by prompted-and, to a lesser extent, spontaneous-requests. Social engagement ratings were higher during each intervention than at baseline, but differences between treatment conditions were not consistent across children.

CONCLUSIONS

For children with autism, naturalistic interventions that use direct elicitation of child language lead to greater short-term gains in the use of expressive language targets-in particular, prompted requests-than interventions that use facilitative strategies only. All 3 naturalistic language interventions can promote social engagement. For some children, the combined use of direct elicitation and responsiveness-based strategies may enhance treatment response.

Recent Advances in Early Identification and Treatment of Autism

Currently, autism spectrum disorders (ASD) can be reliably diagnosed between the ages of 2 and 3 years. Efforts to identify symptoms of ASD in younger children are underway. Recent evidence suggests that children with ASD show reduced rates of early nonverbal social-communication skills by about 12 months, although diagnosis before age 2 remains a challenge. These early social-communication skills can be improved with targeted intervention, and doing so may produce broader improvements in later-emerging skills. Research is beginning to explore the use of these interventions with toddlers, with some success. Despite these advances, much is still unknown about the early presentation of ASD or the best way to intervene.

Pilot randomized controlled trial of Reciprocal Imitation Training for teaching elicited and spontaneous imitation to children with autism

Children with autism exhibit significant deficits in imitation skills. Reciprocal Imitation Training (RIT), a naturalistic imitation intervention, was developed to teach young children with autism to imitate during play. This study used a randomized controlled trial to evaluate the efficacy of RIT on elicited and spontaneous imitation skills in 21 young children with autism. Results found that children in the treatment group made significantly more gains in elicited and spontaneous imitation, replicating previous single-subject design studies. Number of spontaneous play acts at pre-treatment was related to improvements in imitation during the intervention, suggesting that children with a greater play repertoire make greater gains during RIT.

Broader autism phenotype and nonverbal sensitivity: evidence for an association in the general population

This study examined the relationship between characteristics of the Broader Autism Phenotype (BAP) and nonverbal sensitivity, the ability to interpret nonverbal aspects of communication, in a non-clinical sample of college students. One hundred and two participants completed a self-report measure of the BAP, the Autism Spectrum Quotient (AQ), and two tests of nonverbal sensitivity, the Test of Nonverbal Cue Knowledge (TONCK), and the Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA2). AQ score was correlated with TONCK performance and number of errors on the adult faces subtest of the DANVA2, but not adult paralanguage or postures. These findings suggest that characteristics of ASD in the general population are associated with differences in both explicit and implicit knowledge of nonverbal cues.

The impact of object and gesture imitation training on language use in children with autism spectrum disorder

PURPOSE

Reciprocal imitation training (RIT) is a naturalistic behavioral intervention that teaches imitation to children with autism spectrum disorder (ASD) within a social-communicative context. RIT has been shown to be effective at teaching spontaneous, generalized object and gesture imitation. In addition, improvements in imitation are associated with increases in verbal imitation and spontaneous language.

METHOD

This study used a modified multiple-baseline design across 4 children to examine whether adding gesture imitation training improves the overall rate of appropriate language use in children with ASD who have already been participating in object imitation training.

RESULTS

Three of the 4 children showed greater improvements in their use of appropriate language after gesture imitation was begun. Further, the children were more likely to use verbal imitation during gesture imitation training than during object imitation training.

CONCLUSION

These findings suggest that adding gesture imitation training to object imitation training can lead to greater gains in rate of language use than object imitation alone. Implications for both language development and early intervention are discussed.

Teaching the imitation and spontaneous use of descriptive gestures in young children with autism using a naturalistic behavioral intervention

Children with autism exhibit deficits in the imitation and spontaneous use of descriptive gestures. Reciprocal Imitation Training (RIT), a naturalistic imitation intervention, has ben shown to increase object imitation skills in young children with autism. A single-subject, multiple-baseline design across five young children with autism was used to determine whether RIT could be adapted to target the imitation of descriptive gestures. All participants increased their imitation of gestures in the treatment setting and on a structured imitation assessment. Gains generalized to a novel therapist, setting, and materials and maintained at a 1-month follow-up. Three participants also increased their spontaneous use of descriptive gestures. These results provide support for the effectiveness of a naturalistic intervention for teaching gesture imitation.

The Collateral Effects of Joint Attention Training on Social Initiations, Positive Affect, Imitation, and Spontaneous Speech for Young Children with Autism

Joint attention may be a core deficit in autism which underlies the abnormal development of later emerging social-communication behaviors. Given this theory, researchers have suggested that teaching young children with autism to engage in joint attention may lead to collateral increases in other non-targeted social-communication behaviors. In this study, children with autism participated in a 10-week joint attention training program and collateral changes in non-targeted behaviors were assessed. Following participation in the intervention, positive collateral changes were observed in social initiations, positive affect, imitation, play, and spontaneous speech. Results support the hypothesis that teaching joint attention skills leads to improvement in a variety of related skills and have implications for the treatment of young children with autism.

Teaching reciprocal imitation skills to young children with autism using a naturalistic behavioral approach: effects on language, pretend play, and joint attention

Children with autism exhibit significant deficits in imitation skills which impede the acquisition of more complex behaviors and socialization, and are thus an important focus of early intervention programs for children with autism. This study used a multiple-baseline design across five young children with autism to assess the benefit of a naturalistic behavioral technique for teaching object imitation. Participants increased their imitation skills and generalized these skills to novel environments. In addition, participants exhibited increases in other social-communicative behaviors, including language, pretend play, and joint attention. These results provide support for the effectiveness of a naturalistic behavioral intervention for teaching imitation and offer a new and potentially important treatment option for young children who exhibit deficits in social-communicative behaviors.

Effect of Sensory Feedback on Immediate Object Imitation in Children with Autism

This study examined the effect of sensory feedback (e.g., flashing lights and sound) on the imitation performance of children with autism and typical children group-matched for mental age. Participants were administered an immediate object-imitation task with six novel toys constructed for this study: three with a sensory effect that could be activated by imitating the modeled action and three without a sensory effect. Although overall imitation performance did not differ significantly between the two groups, the imitation performance of the participants with autism was significantly higher with sensory toys than with nonsensory toys. Typical participants' imitation performance did not differ between the two sets of toys. Both groups played significantly more with the sensory toys during free play, indicating that sensory toys were more reinforcing for both groups. Additional results demonstrated that typical children used significantly more social behaviors during imitation than children with autism, but they did not differ in object-oriented behaviors, replicating previous findings. It is argued that children with autism may be less motivated to imitate by social interaction, but may be motivated to imitate to receive a nonsocial reward (sensory feedback).

Enhancing conversation skills in children with autism via video technology. Which is better, "self" or "other" as a model?

The present study was designed to compare the efficacy of "self" versus "other" video-modeling interventions. Five children with autism ranging in age from 4 to 11 were taught to answer a series of conversation questions in both self and other video-modeled conditions. Results were evaluated using a combination of a multiple baseline and alternating treatments design. Three out of the five participants performed at levels of 100% accuracy at posttreatment. Results indicated no overall difference in rate of task acquisition between the two conditions, implying that children who were successful at learning from video in general, learned equally as well via both treatment approaches. Anecdotal evidence suggested that participants who were successful with video treatment had higher visual learning skills than children who were unsuccessful with this approach. Results are discussed in terms of a visual learning model for children with autism.
