Measuring Parent-Child Transactions for Early Identification of Young Autistic Children.

This study explored the salient characteristics of transactions within parent-child engagement and investigated relationships between transactional characteristics and future identification of autism. The main aims of the study were to (1) examine if parents/children and their initial behaviors impact the length of transaction; (2) determine miscue differences among parents and children; and (3) determine if transactional characteristics are predictive of autism at preschool age.The study sample was drawn from extant data of a parent-mediated intervention for young children showing early sings of autism. Thirty parent-child dyad videos were randomly selected and coded for transactions. Statistical analyses were applied to examine the study aims and to perform post-hoc analyses.The length of transaction increased when children initiated with a look cue. Parents displayed a higher proportion of miscues and greater variance in their miscue behavior than their children. Neither the length of transaction nor the proportion of child miscues at 1-year of age predicted an autism diagnosis at preschool age. Post-hoc analyses revealed that girls with high variance of transaction length at 1-year of age, had a lower likelihood of showing autism traits at preschool age. Sustained transactions were more likely when children initiated engagement by looking. Early transactional characteristics were associated with later autism identification among girls, namely longer median transaction length with lower variance of transaction length. This transaction profile is believed to represent high fixation on topics with less ability to explore varied topics.

Screening for Speech and Language Delay and Disorders in Children 5 Years or Younger: Evidence Report and Systematic Review for the US Preventive Services Task Force.

Importance: Children with speech and language difficulties are at risk for learning and behavioral problems. Objective: To review the evidence on screening for speech and language delay or disorders in children 5 years or younger to inform the US Preventive Services Task Force. Data Sources: PubMed/MEDLINE, Cochrane Library, PsycInfo, ERIC, Linguistic and Language Behavior Abstracts (ProQuest), and trial registries through January 17, 2023; surveillance through November 24, 2023. Study Selection: English-language studies of screening test accuracy, trials or cohort studies comparing screening vs no screening; randomized clinical trials (RCTs) of interventions. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, study quality, and data extraction; results were narratively summarized. Main Outcomes and Measures: Screening test accuracy, speech and language outcomes, school performance, function, quality of life, and harms. Results: Thirty-eight studies in 41 articles were included (N = 9006). No study evaluated the direct benefits of screening vs no screening. Twenty-one studies (n = 7489) assessed the accuracy of 23 different screening tools that varied with regard to whether they were designed to be completed by parents vs trained examiners, and to screen for global (any) language problems vs specific skills (eg, expressive language). Three studies assessing parent-reported tools for expressive language skills found consistently high sensitivity (range, 88%-93%) and specificity (range, 88%-85%). The accuracy of other screening tools varied widely. Seventeen RCTs (n = 1517) evaluated interventions for speech and language delay or disorders, although none enrolled children identified by routine screening in primary care. Two RCTs evaluating relatively intensive parental group training interventions (11 sessions) found benefit for different measures of expressive language skills, and 1 evaluating a less intensive intervention (6 sessions) found no difference between groups for any outcome. Two RCTs (n = 76) evaluating the Lidcombe Program of Early Stuttering Intervention delivered by speech-language pathologists featuring parent training found a 2.3% to 3.0% lower proportion of syllables stuttered at 9 months compared with the control group when delivered in clinic and via telehealth, respectively. Evidence on other interventions was limited. No RCTs reported on the harms of interventions. Conclusions and Relevance: No studies directly assessed the benefits and harms of screening. Some parent-reported screening tools for expressive language skills had reasonable accuracy for detecting expressive language delay. Group parent training programs for speech delay that provided at least 11 parental training sessions improved expressive language skills, and a stuttering intervention delivered by speech-language pathologists reduced stuttering frequency.

Short report: The role of oral hypersensitivity in feeding behaviors of young autistic children.

LAY ABSTRACT: Feeding problems are common among autistic children and are linked to negative health consequences. Therefore, understanding feeding problems and factors that influence these behaviors is important for developing supports for children and families. While certain sensory processing patterns are commonly associated with feeding problems, less is known about the link between sensory processing and feeding behaviors in autism, as well as how parent behaviors and feelings during mealtime differ based on child sensory preferences. This research examined two groups of young autistic children who were reported to be picky eaters by their parents: those with and those without oral hypersensitivity. Children with oral hypersensitivity had more difficulty with food acceptance and their parents reported more negative feelings around feeding their child. However, the two groups of children (oral hypersensitive and not) did not differ in their medical/oral motor symptoms, mealtime behavior, or parent use of strategies at mealtimes. This research supports the need for personalized treatment strategies based on the child's sensory preferences to support both the child and parent in managing mealtimes.

Measuring Transactional Engagement Among Young Children with Elevated Likelihood for Later Autism Spectrum Disorder Diagnosis.

This analytical study documented the presence of transactions in parent-child engagement within a sample of young children at an elevated likelihood for an eventual diagnosis of autism spectrum disorder (ASD). Specifically, the study examined the establishment of transactional engagement through reciprocal behaviors between parents and their young children at-risk for ASD. In the study sample, established transactional engagement occurred at a higher rate than other levels of engagement. Additionally, transactional engagement had a higher likelihood of being established when parents initiated. Post-hoc analyses revealed possible early markers of ASD within a certain behavior displayed in transactions. This study signifies the initial efforts in identifying transactions within parent-child engagement, and foremost, how transactional engagement is established.

Patterns in reporting and participant inclusion related to race and ethnicity in autism intervention literature: Data from a large-scale systematic review of evidence-based practices.

LAY ABSTRACT: Researchers who study autism-related interventions do a poor job reporting data related to the race and ethnicity of autistic individuals who participate in their studies, and of those who do report these data, the participants are overwhelmingly White. This is problematic for many reasons, as we know little about how interventions are meeting the needs of culturally and linguistically diverse populations, and we assume that interventions are effective for all when they have been developed and validated primarily with and for White children. This study examined the reporting patterns of autism intervention researchers whose work was included in a large-scale systematic review of the intervention literature published between 1990 and 2017. We found that only 25% of studies (out of 1,013 included in the review) included data related to the race and ethnicity of their participants, with minimal change in reporting patterns across the years. In studies with reported data, White participants had the highest rate of participation, with a large gap between the next highest rates of participation among Hispanic/Latino, Black, and Asian participants. Other race and ethnicity groups had very low representation. This study includes additional analyses which examine how the reporting patterns and the inclusion of racially and ethnically diverse participants varies across study types, interventions, and outcome areas. Reporting this data is merely a starting point to begin to address the many disparities in autism-related healthcare, education, and research practices, and this article includes broader implications and next steps to ensure the field becomes more equitable and inclusive.

Use of the Children's Communication Checklist-2 in School-Aged Students with Autism: A Psychometric Analysis.

Measurement of social-pragmatic communication skills is essential for clinicians and researchers working with school-aged children on the autism spectrum. Many measures of these skills require time-intensive training and coding that is impractical for clinical assessment settings. Using a sample of 299 elementary school children (M = 8.6 years, sd = 1.7) with autism whose teachers completed the Children's Communication Checklist-2, we evaluated the psychometric properties of the CCC-2, a commonly used measure of social-pragmatic skills in order to assist researchers and clinicians in identifying the utility of this measure related to their assessment needs. Our results indicate strong psychometric properties for the CCC-2 with this population and a 3-factor model fit: Structural Language, Pragmatic Communication, and Pragmatic Social. Evidence of racial/ethnic bias was found for the structural language factor. Clinical recommendations are provided for using the CCC-2 with students with autism as reported by teachers.

Parent responsiveness mediates the association between hyporeactivity at age 1 year and communication at age 2 years in children at elevated likelihood of ASD.

Studies suggest that higher parent responsiveness is associated with higher child language abilities. Infants and toddlers later diagnosed with autism spectrum disorder (ASD) often display hyporeactivity to sensory stimuli, which has also been associated with lower child communication abilities and lower parent responsiveness. Yet, whether parent responsiveness mediates the relationship between child hyporeactivity and later communication outcomes remains unexplored. This study is a secondary data analysis which includes children (n = 83; 56 males) identified as at elevated likelihood of later ASD. Children completed an observational measure of sensory reactivity and a standard developmental assessment at 14 (Time 1) and 23 months old (Time 2). At each time point, parents reported on the child's adaptive communication behaviors and sensory behaviors, and Parent Verbal Responsiveness (AvgPVR) was coded from parent-child free-play videos. Results indicated that the association between child sensory hyporeactivity at Time 1 (observed and parent-reported) and communication at Time 2 (observed and parent reported) was significantly mediated by AvgPVR. Although child hyporeactivity predicts poorer communication outcomes, increased parent verbal responsiveness may attenuate this negative impact. Parent responsiveness, a focus of many parent-mediated interventions, may be an important mechanism of treatment response that should be directly tested in future research. LAY SUMMARY: Toddlers at elevated likelihood of autism spectrum disorder (ASD) are often under-reactive (hyporeactive) to sensory stimuli. This hyporeactivity slows learning of communication skills and provides parents with fewer opportunities to respond to their children. In this study, children with hyporeactivity at 14 months generally had poorer communication at 23 months; however, the more responsive their parents were, the weaker the relationship between early hyporeactivity and later communication. Thus, increasing parent responsiveness may lead to better communication outcomes for toddlers with the early ASD symptom of hyporeactivity.

Educational Interventions for Children and Youth with Autism: A 40-Year Perspective.

Commemorating the 40 th anniversary of the Diagnostic and Statistical Manual (DSM) III, the purpose of this commentary is to describe school-based and school-relevant interventions and instructional approaches for children and youth with autism that have been developed and employed during that time period. The commentary begins with a brief description of foundational research that provides an historical context. Research themes shaped by science, ethics, social policy, and the changes in the DSM provide an organization for describing the evolution of intervention and instructional practices over the four previous decades. The commentary concludes with a discussion of school-contextual variables that influence implementation and the promise of the "iSciences" for closing the research to practice gap in the future.

Evidence-Based Practices for Children, Youth, and Young Adults with Autism: Third Generation Review.

This systematic review describes a set of practices that have evidence of positive effects with autistic children and youth. This is the third iteration of a review of the intervention literature (Odom et al. in J Autism Dev Disorders 40(4):425-436, 2010a; Prevent School Fail 54(4):275-282, 2010b; Wong et al. in https://autismpdc.fpg.unc.edu/sites/autismpdc.fpg.unc.edu/files/imce/documents/2014-EBP-Report.pdf ; J Autism Dev Disorders 45(7):1951-1966, 2015), extending coverage to articles published between 1990 and 2017. A search initially yielded 31,779 articles, and the subsequent screening and evaluation process found 567 studies to include. Combined with the previous review, 972 articles were synthesized, from which the authors found 28 focused intervention practices that met the criteria for evidence-based practice (EBP). Former EBPs were recategorized and some manualized interventions were distinguished as meeting EBP criteria. The authors discuss implications for current practices and future research.

Joint Attention and Sensory-Regulatory Features at 13 and 22 Months as Predictors of Preschool Language and Social-Communication Outcomes.

Purpose The purpose of this study was to understand how joint attention and sensory-regulatory features are related in early childhood and predict language and social-communication outcomes in preschool in order to build mechanistic theories that can inform early intervention directed at improving these outcomes. Method Cross-lagged panel analysis models were used to examine the association between joint attention and sensory-regulatory features at 13 and 22 months of age in children (n = 87) who were identified via community screening at 12 months as having a higher likelihood than the general population for being diagnosed with autism spectrum disorder. Results Significant concurrent correlations and predictive correlations were found between these constructs at 13 and 22 months. Joint attention skills at 13 months predicted both joint attention and sensory-regulatory features at 22 months. Distal language and social-communication outcomes at preschool age (n = 48) were best predicted by sensory-regulatory features at 22 months. Conclusions Both joint attention and sensory regulation are important factors in the first and second years of life for impacting later preschool language and social-communication outcomes in this sample. These findings may have implications for future early childhood intervention research for children at a higher likelihood for autism spectrum disorder.

Sensory Reactivity at 1 and 2 Years Old is Associated with ASD Severity During the Preschool Years.

Children with Autism Spectrum Disorder (ASD) often display atypical sensory reactivity within the first years of life, prior to a diagnosis. This study examined sensory reactivity patterns at 14 months, changes from 14 to 23 months, and later ASD severity at 3 to 5 years of age in children (n = 87) at elevated likelihood of ASD. Results indicated that observed hyporeactivity at 14 months and increases from 14 to 23 months were related to higher ASD severity during the preschool years. Parent report of hyperreactivity at 14 months was associated with higher ASD severity in the RRB domain during the preschool years. Early hypo and hyperreactivity may predict later severity of ASD and aid in subtyping and developing individualized treatments.

Social and Object Attention Is Influenced by Biological Sex and Toy Gender-Congruence in Children With and Without Autism.

Emerging research suggests social attention in autism spectrum disorder (ASD) girls is enhanced relative to ASD boys but may also be affected by the type of social and nonsocial content presented. This study examined how biological sex and gender norms interact to influence visual attention in 79 school-aged children observing scenes that included gender-associated toys and actors of both sexes. Attention to social (faces) and object activity (hands with toys) stimuli was measured. Previously described distinctions between social attention in ASD boys and girls were replicated, with ASD girls looking more at faces than ASD boys. Irrespective of diagnosis, males and females attended more to actors that shared their same sex, and attended more to toys with gender-associations that were consistent with their own sex, suggesting that social and object salience increases for children under sex-consistent conditions. Importantly, ASD and typically developing (TD) children increased their gaze to faces when male actors were shown playing with female-associated toys, suggesting that both groups of children are sensitive to societal messages about the acceptability of males playing with female-associated toys. Our findings provide further evidence of heightened attention to faces in ASD girls relative to ASD boys, and indicate that social attention in ASD and TD children is influenced by who (male or female actor) and what (male- or female-associated toy) is being observed. Collectively, these results present a nuanced profile of attention in ASD that adds to a growing body of research indicating subtle phenotypic differences in ASD girls that may impact identification, assessment, and intervention. Autism Res 2020, 13: 763-776.. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Sex differences observed in typical development may also be present in individuals with autism. In this study, we developed an eye-tracking paradigm featuring videos of boys and girls playing with toys that varied in their gender associations. Attention to faces differed between autistic and non-autistic children but was also influenced by the sex of the actor and gender-association of toys. Autistic females demonstrated subtle attention differences that distinguished them from autistic males and may influence referral, diagnosis, and intervention.

Visual attention to faces in children with autism spectrum disorder: are there sex differences?

Background: The male bias in autism spectrum disorder (ASD) diagnoses is well documented. As a result, less is known about the female ASD phenotype. Recent research suggests that conclusions drawn from predominantly male samples may not accurately capture female behavior. In this study, we explore potential sex differences in attention to social stimuli, which is generally reported to be diminished in ASD. Population-based sex differences in attention to faces have been reported, such that typically developing (TD) females attend more to social stimuli (including faces) from infancy through adulthood than TD males. It is yet unknown whether population-based sex differences in the face domain are preserved in ASD. Methods: A dynamic, naturalistic infrared eye-tracking paradigm measured attention to social stimuli (faces) in 74 school-aged males and females with ASD (male N = 23; female N = 19) and without ASD (male N = 16; female N = 16). Two kinds of video stimuli were presented that varied in social content: rich social scenes (dyadic play between two children) and lean social scenes (parallel play by two children). Results: Results revealed a significant 3-way interaction between sex, diagnosis, and condition after controlling for chronological and mental age. ASD females attended more to faces than ASD males in the socially lean condition. This effect was not found in the typically developing (TD) group. ASD males attended less to faces regardless of social context; however, ASD females only attended significantly less to faces compared to TD females in the socially rich condition. TD males and ASD females did not differ in their attention to faces in either condition. Conclusions: This study has implications for how the field understands core social deficits in children with ASD, which should ideally be benchmarked against same-sex peers (male and female). Social attention in ASD females fell on a continuum-greater than their ASD male peers, but not as great as TD females. Overall, their social attention mirrored that of TD males. Improved understanding of the female social phenotype in ASD will enhance early screening and diagnostic efforts and will guide the development of sex-sensitive experimental paradigms and social interventions.

Efficacy Study of a Social Communication and Self-Regulation Intervention for School-Age Children With Autism Spectrum Disorder: A Randomized Controlled Trial.

Purpose This study aimed to examine the initial efficacy of a parent-assisted blended intervention combining components of Structured TEACCHing and Social Thinking, designed to increase social communication and self-regulation concept knowledge in 1st and 2nd graders ( n = 17) diagnosed with autism spectrum disorder (ASD) and their parents. Method A randomized delayed treatment control group design with pre- and postintervention assessments of both parents and children was implemented within a community practice setting. Two follow-up assessments at 3 and 6 months postintervention were also completed. Results Overall, results indicate that the intervention is efficacious in teaching social communication and self-regulation concept knowledge to children with ASD and their parents. Both parents and children demonstrated an increase in social communication and self-regulation knowledge after participating in the Growing, Learning, and Living With Autism Group as compared to a delayed treatment control group. The effects of the intervention did not extend to parent-child interactions coded from video recordings. Child treatment effects were maintained at the 3- and 6-month follow-up assessments. Conclusions Preliminary efficacy of the Growing, Learning, and Living With Autism Group was established. Based on parent report at the conclusion of the intervention, this is a socially valid intervention for teaching social communication and self-regulation skills to school-age children with ASD.

Sex differences in social attention in autism spectrum disorder.

Although reduced social attention and increased nonsocial attention have been reported in individuals with autism spectrum disorder (ASD), the studies have relied on predominantly male samples and have been underpowered to examine sex differences. These processes may differ for females with ASD, who have been shown to be dissimilar to males in social motivation and nonsocial features, including circumscribed interests (CI). The goal of this study was to compare social and nonsocial visual attention between males and females with ASD on a validated eye-tracking paradigm. Eighty-five school-aged (6-10 years) males and females with and without ASD completed a paired preference task of face and object stimuli (half of which related to common CI). After covarying for chronological and mental age, the presence of concurrently presented CI images reduced prioritization and attention to faces for males more than females, replicating previous findings. ASD females maintained comparable attention patterns to typically developing females, suggesting that previous findings of reduced social attention and increased attention to CI-related objects in autism may be specific to males. These findings are also inconsistent with the "extreme male brain" theory of autism. The more normative orienting and attention to social stimuli for females with ASD may indicate distinct phenotypic characteristics relative to males and possibly serve as a protective effect. Autism Res 2018, 11: 1264-1275. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: As autism is more commonly diagnosed in males, less is known about females with autism. Two areas of interest include the interests held by individuals with autism and how socially motivated they are. We used eye tracking as a way to understand these two areas. Our data reveal that elementary school-aged females (6-10 years) with autism attended to faces comparatively to females without autism, suggesting that (1) they were more socially motivated than males with autism and (2) the images of common interests were less motivating to them.

Circumscribed Interests and Attention in Autism: The Role of Biological Sex.

Recent studies suggest that circumscribed interests (CI) in females with Autism Spectrum Disorder (ASD) may align more closely with interests reported in typical female development than those typically reported for ASD males. We used eye-tracking to quantify attention to arrays containing combinations of male, female and neutral images in elementary-aged males and females with and without ASD. A number of condition × sex effects emerged, with both groups attending to images that corresponded with interests typically associated with their biological sex. Diagnostic effects reported in similar studies were not replicated in our modified design. Our findings of more typical attention patterns to gender-typical images in ASD females is consistent with evidence of sex differences in CI and inconsistent with the "Extreme Male Brain" theory of ASD.

An Initial Psychometric Evaluation of the Joint Attention Protocol.

The goal of this paper is to examine the psychometric properties of a live-coded behavioral measure of joint attention, the Attention-Following and Initiating Joint Attention Protocol (JA Protocol), in order to assist researchers and clinicians in identifying when this measure may meet their joint attention assessment needs. Data from 260 children with autism spectrum disorder, developmental delay, or typical development between the ages of 2 and 12 years were used to evaluate this measure using quality standards for measurement. Overall, the JA Protocol demonstrated good psychometric properties. Recommendations and limitations for use of this measure based on psychometric analysis results are reported.

Cascading effects of attention disengagement and sensory seeking on social symptoms in a community sample of infants at-risk for a future diagnosis of autism spectrum disorder.

Recent work suggests sensory seeking predicts later social symptomatology through reduced social orienting in infants who are at high-risk for autism spectrum disorder (ASD) based on their status as younger siblings of children diagnosed with ASD. We drew on extant longitudinal data from a community sample of at-risk infants who were identified at 12 months using the First Year Inventory, and followed to 3-5 years. We replicate findings of Damiano et al. (in this issue) that a) high-risk infants who go on to be diagnosed with ASD show heightened sensory seeking in the second year of life relative to those who do not receive a diagnosis, and b) increased sensory seeking indirectly relates to later social symptomatology via reduced social orienting. We extend previous findings to show that sensory seeking has more clinical utility later in the second year of life (20-24 months) than earlier (13-15 months). Further, this study suggests that diminished attention disengagement at 12-15 months may precede and predict increased sensory seeking at 20-24 months. Findings add support for the notion that sensory features produce cascading effects on social development in infants at risk for ASD, and suggest that reduced attention disengagement early in life may set off this cascade.

Parent-Mediated Intervention for One-Year-Olds Screened as At-Risk for Autism Spectrum Disorder: A Randomized Controlled Trial.

Theoretically, interventions initiated with at-risk infants prior to the point in time a definitive autism spectrum disorder (ASD) diagnosis can be made will improve outcomes. Pursuing this idea, we tested the efficacy of a parent-mediated early intervention called Adapted Responsive Teaching (ART) via a randomized controlled trial with 87 one-year-olds identified by community screening with the First Year Inventory as at-risk of later ASD diagnoses. We found minimal evidence for main effects of ART on child outcomes. However, ART group parents showed significantly greater increases in responsiveness to their infants than control group parents. Further, significant indirect (mediation) effects of assignment group on multiple child outcomes through changes in parent responsiveness supported our theory of change.
