Adapting the Early Communication Indicator as a Social Communication Outcome Measure for Young Autistic Children: A Pilot Study.

We sought to conduct a pilot investigation of the reliability and administration fidelity of a new play-based measure of social communication for infants and toddlers with an autism diagnosis. Our team adapted an existing measure, the Early Communication Indicator (ECI), for use with young autistic children in clinical and research contexts. In this brief report, we detail our adaptation process including administration and scoring of the final adapted measure based on data from a two-phase pilot study with young autistic children (N = 17). This adapted measure, the Early Communication Indicator-Autism (ECI-A), captured a range of scores for the ECI, Initiation of Joint Attention, and Directed Communication in pilot testing. Interrater reliability was moderate to strong across the scored behaviors. Finally, parents were able to administer the ECI-A with high fidelity with support from the research staff. This two-phase pilot study demonstrated promise for the ECI-A as a brief measure of social communication that can be administered by parents and reliably scored by trained staff with limited background in autism assessments. Validation of the ECI-A is presently underway. https://doi.org/10.23641/asha.26042077.

Autistic Children's Irritability During Social Communication Assessments.

Accurate measurement of autistic children's social communication is critical for assessing skills, setting intervention goals, evaluating change over time, determining service eligibility, and determining classroom placement. There are various types of assessments, some of which use specific tasks to elicit social communication. Structured tasks may frustrate children, inadvertently elicit irritability, and have a cascading effect on their ability to communicate. To date, no studies have evaluated how differing types of social communication assessments may exacerbate children's irritability and impact assessment scores. We examined the extent to which (a) social communication assessment type (structured vs. naturalistic) impacts autistic children's irritability and (b) child irritability is associated with social communication scores. Autistic toddlers (n = 114, Mage = 33.09 months, SD = 6.15) completed the Communication and Symbolic Behavior Scales (CSBS; structured) and a 10-min play-based mother-child interaction (MCX; naturalistic). Child irritability was scored on both assessments using a global rating scale of 0-15. Child irritability during the CSBS was significantly higher than during the MCX (V = 4892, p < .001, r = .68). Higher irritability was associated with lower CSBS social communication scores (B = -0.05, p = .03), but not MCX scores (B = 0.04, p = .13; Theil's F = 6.92, p = .009). Our findings suggest that the CSBS may pose unique challenges for autistic children, as it led to higher rates of irritability and negatively affected children's social communication scores. Evaluating the association between assessment type and irritability supports the complete characterization of autistic children's experience during assessments and clinicians in obtaining a more representative measure of social communication.

A Comparative Analysis of the Full and Short Versions of the Social Responsiveness Scale in Estimating an Established Autism Risk Factor Association in ECHO: Do we Get the Same Estimates?

Prior work developed a shortened 16-item version of the Social Responsiveness Scale (SRS), a quantitative measure of social communication and autism spectrum disorder (ASD)-related traits. However, its properties for use in risk factor estimation have not been fully tested compared to the full SRS. We compared the associations between gestational age (previously established risk factor for ASD) and the 65-item "full" and 16-item "short" versions of the SRS to test the shortened version's ability to capture associations in epidemiologic analyses of ASD risk factors. We used data from participants in the Environmental influences on Child Health Outcomes (ECHO) Program (n = 2,760). SRS scores were collected via maternal/caregiver report when children were aged 2.5-18 years. We compared estimates of associations between gestational age and preterm birth between the full and short SRS using multivariable linear regression, quantile regression, and prediction methods. Overall, associations based on full and short SRS scores were highly comparable. For example, we observed positive associations between preterm birth with both full ([Formula: see text]=2.8; 95% CI [1.7, 4.0]) and short ([Formula: see text]=2.9; 95% CI [1.6, 4.3]) SRS scores. Quantile regression analyses indicated similar direction and magnitude of associations across the distribution of SRS scores between gestational age with both short and full SRS scores. The comparability in estimates obtained for full and short SRS scores with an "established" ASD risk factor suggests ability of the shortened SRS in assessing associations with potential ASD-related risk factors and has implications for large-scale research studies seeking to reduce participant burden.

Abbreviating the Early Start Denver Model for community-based family-centered care.

Parent-mediated approaches for young children with or with a higher likelihood of autism have gained traction, with mounting evidence of efficacy, but a research-to-gap practice exists, and community effectiveness remains to be firmly established. Using a community-participatory framework, a total of 10 parent-child dyads received a five-day workshop and six follow-up sessions of ESDM parent coaching. Intervention was implemented across two phases with in-person and telehealth delivery. From pre to post intervention across both phases, parents improved in their fidelity of intervention implementation and children maid gains on proximal measures of social communication. Community delivery of an evidence-based parent-mediated interventions for toddlers on the autism spectrum is feasible and promising. Giving resource efficiencies associated with parent-mediated approaches, particularly when delivered through government-funded programs, findings bolster current efforts to promote earlier and more widespread community access to necessary interventions. Facilitators and barriers to supporting parent learning and behavior change via interactive strategies are discussed.

Screening for Social Communication and Mental Health Needs in Schools: Initial Validation of the School-Based Social Communication Skill Set Screener (SBSCSSS)

Social communication is closely related to overall and general adolescent mental health and predictive of problem behaviors in adulthood. However, adolescents with social communication deficits remain an underidentified and underserved population, especially in school-based settings. In part, this is due to the dearth of social communication measures developed for use, and within, school contexts. The School-Based Social Communication Skill Set Screener (SBSCSSS) was developed as a schoolwide rapid assessment measure for students’ perceptions of their own skills and problems stemming from potential social communication issues. This study aims to provide initial psychometric evidence for the SBSCSSS by analyzing a data set of schoolwide needs assessment responses conducted at an urban Appalachian high school. Exploratory factor analyses identified a three-factor structure across 23 items. Internal consistency calculations found that each factor, including a global factor, had high levels of internal consistency. Convergent validity findings are also provided. Initial psychometric evidence for the SBSCSSS indicates a potential valid and reliable tool to examine perceived social communication skills for high school students. The article concludes with a discussion of the implications for future research and practice.

Non-linguistic comprehension, social inference and empathizing skills in autistic young adults, young adults with autistic traits and control young adults: Group differences and interrelatedness of skills.

Despite increasing knowledge of social communication skills of autistic peole, the interrelatedness of different skills such as non-linguistic comprehension, social inference and empathizing skills is not much known about. A better understanding of the complex interplay between different domains of social communication helps us to develop assessment protocols for individuals with social communication difficulties. To compare the performances of autistic young adults, young adults with autistic traits identified in childhood and control young adults in social communication tasks measuring non-linguistic comprehension, social inference and empathizing skills. In addition, to examine associations between the different social communication measures. Autistic young adults (n = 34), young adults with autistic traits (n = 19) and control young adults (n = 36) completed the extra- and paralinguistic scales of the Assessment Battery for Communication (ABaCo), the Faux Pas Recognition Test, Social-Pragmatic Questions (SoPra) and the Empathy Quotient (EQ). Group differences were found in the performance in the ABaCo, SoPra and EQ scores. Compared with the control young adults, autistic young adults scored lower. The performance of the young adults in the autistic traits group fell in between the other two groups. There were no group differences in the Faux Pas Recognition Test. The variability within the groups was large in all measurements. In the control group, there was a significant correlation between EQ and SoPra scores and between the Faux Pas and SoPra scores. In the autistic group, a significant correlation was found between Faux Pas and SoPra scores. Also, other patterns were observed but these were not statistically significant. The young adults with autistic traits fell in between the control and autistic young adults, highlighting the presence of the continuum in the terms of features of social communication. The results support other current research that suggests that theory of mind and other social communication skills may not be universally or widely impaired in all autistic individuals without cognitive deficits. Although all tasks examined social communication skills, only a small number of significant correlations were found between test scores. This highlights that clinical conclusions about a person's social communication should be based on the outcomes of different types of methods measuring different aspects of social communication. It is clear that the interrelatedness of different social communication skills needs further research. What is already known on this subject For successful communication, the ability to infer others' emotions, intentions and mental states is crucial. Autistic people have difficulty with many aspects of social communication. However, the associations between different aspects of social communication need to be better understood. What this paper adds to existing knowledge The unique contribution of this study is to compare the performance of autistic people not only with that of a control group but also with people with childhood autistic traits. This provides an understanding of the interrelatedness of different social communication skills in people with varying degrees of autistic traits. This study used four assessment methods focusing on three different social communication elements (non-linguistic comprehension, social inference and empathizing skills). These elements have complex relationships to one another, some being closely overlapping, some more distally related and some reflect more complex multifactorial elements. This study shows that although groups differ from each other in most of the assessments, the performance of different groups overlapped showing that many autistic young adults can perform well in non-linguistic and social inference tasks in structured assessment contexts. What are the potential or actual clinical implications of this work? Our findings suggest that in the assessment of social communication, self-reports and clinical assessments can be used effectively together. They can complement each other, pointing out the strengths and weaknesses of a person, leading to more personalized therapeutic interventions.

Profiles of language and communication abilities in adolescents with fetal alcohol spectrum disorders.

Language and communication are largely understudied among youth with fetal alcohol spectrum disorders (FASD). Findings have been mixed, and have generally focused on more severely affected (i.e., children with FAS alone) or younger children. This study aimed to elucidate the profiles of language (i.e., receptive, expressive, general language) and communication (i.e., functional, social) abilities in adolescents with FASD. Participants aged 12-17 years with (AE = 31) and without (CON = 29) prenatal alcohol exposure were included. Receptive and expressive language were measured by the Clinical Evaluation of Language Fundamentals - Fifth Edition (CELF-5). Parents or caregivers completed the Children's Communication Checklist - Second Edition as a subjective measure of general language skills. Functional communication was measured by the Student Functional Assessment of Verbal Reasoning and Executive Strategies and parents or caregivers completed the Social Skills Improvement System Rating Scales as a measure of social communication. Multivariate analysis of variance determined the overall profiles of language and communication and whether they differed between groups. The AE group performed significantly lower than the CON group on receptive language and parent report of general language while groups did not significantly differ on expressive language. Groups did not significantly differ on functional communication while social communication was significantly lower in the AE group. Results of this study provide important information regarding the overall profile of basic language abilities and higher-level communication skills of adolescents with FASD. Ultimately, improving communication skills of youth with FASD may translate to better overall functioning.

Screening for Autism in 2-Year-Old Children: The Application of the Systematic Observation of Red Flags to the Screening Tool for Autism in Toddlers and Young Children.

A multimeasure approach was developed to capitalize on the strengths of two screening measures: the Screening Tool for Autism in Toddlers and Young Children (STAT), an observational measure of social communication, and the Systematic Observation of Red Flags (SORF), a checklist including restricted and repetitive behavior (RRB) items. This approach offers a novel method of identifying autism in toddlers. This was a retrospective study of data collected from a multidisciplinary diagnostic program for 24- to 36-month-olds with developmental delays. Raters with autism expertise but naïve to diagnoses applied the SORF to STAT videos. Psychometrics were derived for the SORF on STAT observations and a multiple-measure approach that used a Least Absolute Shrinkage and Selection Operator modeling framework to construct a STAT-SORF RRB Hybrid, retaining SORF RRB items based on individual predictive abilities. The SORF alone correctly classified 84% of the sample (84% sensitivity and 86% specificity). The STAT-SORF RRB Hybrid model, which retained four SORF RRB items, correctly classified 90% of a validation sample (95% sensitivity and 75% specificity). These findings highlight the potential utility of using multiple autism identification tools and regression-based scoring to establish presumptive eligibility and facilitate early access to autism interventions.

Early Developmental Trajectories in Infants With Neurofibromatosis 1.

ObjectiveTo examine the trajectories of cognitive, motor and behavioural development in infants with NF1 compared to infants without a family history of neurodevelopmental difficulties.Study designInfants with NF1 and low-risk controls were recruited from 5 months of age and followed longitudinally. Data from standardised tests was gathered at 5, 10 and 14 months and developmental trajectories of motor, language, behaviour, sleep, social development and parent–infant interaction were examined. Linear mixed modelling was used to estimate group differences in cognitive and behavioural measures over time.ResultsNo group differences were observed on Mullen Scale of Early Learning, overall adaptive functioning, temperament or behavioural measures. There were no group differences observed on measures of social communication or parent–infant interaction. Over the course of development, the NF1 group slept less and took more time to settle to sleep as compared to the control group. Maternal education was significantly associated with cognitive and behavioural developmental outcomes in both groups.ConclusionCognitive, social and behavioural impairments are a cause of significant functional morbidity in children with NF1. This report is the first study to investigate the trajectories of cognitive, motor and behavioural development in infancy in NF1. Our results demonstrate that overall cognitive and behavioural developmental trajectories of the NF1 group in the infancy period are similar to controls. Given previous reports of delayed development in the NF1 cohort by 40 months, early clinical interventions strategies to promote sleep hygiene may be beneficial to optimise developmental outcomes.

Prevalence of Postpartum Depression, Associated Factors, Social Support, and Professional Assistance: A Cross-Sectional Study in Port Said, Egypt

INTRODUCTIONPostpartum depression is a mental illness that affects post-childbirth mothers. It is associated with psychological and social risk factors such as negative childhood experiences and pregnancy and childbirth problems. Postpartum depression has not been a focus of concern in Egypt. Therefore, this study aimed to identify the prevalence of postpartum depression, its associated factors, social support, and professional assistance in Port Said, Egypt.METHODOLOGYA random sampling strategy was used to select 540 women ten weeks postpartum. Data were collected using a questionnaire during an interview to identify potential risk factors for postpartum depression. The modified Arabic version of the Edinburgh Postpartum Depression Scale was used to assess symptoms of postpartum depression which is a multidimensional measure of social communication. Statistical analysis was completed using SPSS 25.0. software.RESULTSIt was found that 24.4% of women were at risk for postpartum depression. Social support from family and friends was significantly associated with mitigation of postpartum depression.CONCLUSIONThis study affirmed postpartum depression was a common health problem among 540 women who gave birth in Port Said, Egypt. Early detection and efficient screening methods to detect postpartum depression should be applied, especially in areas with a high risk for this condition. Early detection may prevent complications for mothers, babies, and families.

Effectiveness of a parent-mediated intervention for toddlers with autism spectrum disorder: Evidence from a large community implementation.

In an effort to increase access to intervention as early as possible for toddlers with autism spectrum disorder or signs thereof, many researchers have developed interventions that can be delivered by parents in their own homes. These parent-mediated approaches have gained a lot of research attention in recent years and have been found to be helpful in terms of parent and toddler learning. Several studies have used a rigorous research design (a randomized controlled trial) to show that parent-mediated intervention can work under ideal well-controlled conditions. To build on this evidence, we also need to examine whether parent-mediated interventions can be taught well through community service providers and delivered in more "real-world" conditions. This study used a research-community partnership to provide a parent-mediated intervention (called the Social ABCs) to 179 families (mean toddler age was 25 months; ranging from 14 to 34 months). Almost 90% of the families completed the 12-week program and 70% returned for a follow-up assessment 3 months later. Analyses showed that parents learned the strategies that were designed to help them support their toddlers' development. Also, toddlers made gains in their language, communication, and social skills. Importantly, parents' use of the strategies was related to toddlers' skill gains, suggesting that the use of the strategies made a difference for the toddlers. Findings support the use of parent-mediated intervention in this very young age group and suggest that such intervention approaches should be made available for community delivery.

Neural correlates of face processing associated with development of social communication in 12-month infants with familial risk of autism spectrum disorder

BackgroundDifferences in face processing in individuals with ASD is hypothesized to impact the development of social communication skills. This study aimed to characterize the neural correlates of face processing in 12-month-old infants at familial risk of developing ASD by (1) comparing face-sensitive event-related potentials (ERP) (Nc, N290, P400) between high-familial-risk infants who develop ASD (HR-ASD), high-familial-risk infants without ASD (HR-NoASD), and low-familial-risk infants (LR), and (2) evaluating how face-sensitive ERP components are associated with development of social communication skills.Methods12-month-old infants participated in a study in which they were presented with alternating images of their mother’s face and the face of a stranger (LR = 45, HR-NoASD = 41, HR-ASD = 24) as EEG data were collected. Parent-reported and laboratory-observed social communication measures were obtained at 12 and 18 months. Group differences in ERP responses were evaluated using ANOVA, and multiple linear regressions were conducted with maternal education and outcome groups as covariates to assess relationships between ERP and behavioral measures.ResultsFor each of the ERP components (Nc [negative-central], N290, and P400), the amplitude difference between mother and stranger (Mother-Stranger) trials was not statistically different between the three outcome groups (Nc p = 0.72, N290 p = 0.88, P400 p = 0.91). Marginal effects analyses found that within the LR group, a greater Nc Mother-Stranger response was associated with better expressive language skills on the Mullen Scales of Early Learning, controlling for maternal education and outcome group effects (marginal effects dy/dx = 1.15; p < 0.01). No significant associations were observed between the Nc and language or social measures in HR-NoASD or HR-ASD groups. In contrast, specific to the HR-ASD group, amplitude difference between the Mother versus Stranger P400 response was positively associated with expressive (dy/dx = 2.1, p < 0.001) and receptive language skills at 12 months (dy/dx = 1.68, p < 0.005), and negatively associated with social affect scores on the Autism Diagnostic Observation Schedule (dy/dx = − 1.22, p < 0.001) at 18 months.ConclusionsIn 12-month-old infant siblings with subsequent ASD, increased P400 response to Mother over Stranger faces is positively associated with concurrent language and future social skills.

Knockdown of sexually differentiated vasopressin expression in the bed nucleus of the stria terminalis reduces social and sexual behaviour in male, but not female, mice.

The neuropeptide arginine-vasopressin (AVP) has long been implicated in the regulation of social behaviour and communication, but the sources of AVP release relevant for behaviour have not been precisely determined. Ablations of the sexually dimorphic AVP cells within the bed nucleus of the stria terminalis (BNST), which are more numerous in males, affect social behaviour differently in males and females. However, it is unknown whether these behavioural effects are caused by a reduction of AVP or of other factors associated with these cells. To test the role of AVP specifically, we used an shRNA viral construct to knock down AVP gene expression within the BNST of wild-type male and female mice, using scrambled sequence virus as a control, and evaluated subsequent changes in social behaviours (social investigation, ultrasonic vocalization (USV), scent marking, copulation, and aggression), or anxiety-like behaviours (elevated plus maze). We observed that, in males, knockdown of AVP expression in the BNST strongly reduced investigation of novel males, aggressive signalling towards other males (tail rattling, USV), and copulatory behaviour, but did not alter attack initiation, other measures of social communication, or anxiety-like behaviours. In females, however, BNST AVP knockdown did not alter any of these behaviours. These results point to differential involvement of AVP derived from the BNST in social behaviour.

Coordinated social communication in toddlers with and without autism spectrum disorder during a home observation.

Social communication and language skills have been found to be important predictors of long-term outcomes in individuals with autism spectrum disorder (ASD). However, the development of coordinated social communication (i.e., gestures and sounds or words) remains relatively understudied in young children with ASD and developmental delays (DD). This study used a prospective, longitudinal design and granular observational coding to document the coordination of gestures, sounds, and words in a large, heterogeneous sample of toddlers identified with ASD, DD, or typical development (TD) during a naturalistic home observation. Specific aims were: (1) to compare rates per minute and proportions of coordinated child communicative acts across groups; (2) to examine concurrent relationships between coordinated communication and measures of social communication and autism symptoms; and (3) to examine prospective relationships between coordinated communication, receptive and expressive language skills, and autism symptoms collected at 3 years of age. At a mean age of 20.3 months (SD = 2.0), 211 children (nASD = 121; nDD = 46; nTD = 44) participated in everyday activities with a parent during an hourlong home observation. Rates per minute and proportions of gestures, sounds and words, as well as temporally overlapping gesture + sound, gesture + word, and gesture + phrase combinations, were compared using one-way ANOVA. Pearson product moment correlations between coordinated communicative acts and measures of social communication, language, and autism symptoms were examined. On average, children with ASD used sounds and gesture + sounds at significantly lower rates than DD and TD groups, who did not differ. Children with ASD and DD coordinated gesture + single words and gesture + phrases at significantly lower rates than the TD group. Groups did not differ with respect to the rate per minute at which they used gestures alone. Children with TD used a smaller proportion of sounds alone and higher proportions of words and phrases, with and without coordinated gestures, than ASD and DD groups. Children with ASD and DD used a significantly higher proportion of gestures alone than children with TD. Rates per minute and proportions of single words and gesture + words had significant correlations with measures of social communication, language skills, and autism symptoms. Results suggest that a significantly lower rate per minute of sounds and gesture + sound combinations was a distinguishing feature of ASD in our sample. Further, limited use of single words and gesture + single words was observed in children ASD and DD. Significant prospective relationships between single words and gesture + words with language skills measured over a year later underscores the importance of acquiring these forms. Results support the idea that clinicians should include opportunities to observe and encourage coordinated social communication while screening and assessing young children for DD and ASD in the home environment. The significant associations between rate of single words and gesture + word combinations with language development over a year later have implications for incorporating intervention targets that encourage the use of gesture-speech combinations.

Development of a Social Communication Questionnaire (QSC-ID) for People With Intellectual Disability in a Deaf Sample: A Pilot and Feasibility Study.

Background: Social communication (SC) includes the use and interpretation of verbal and non-verbal messages within a social context and thus requires more than knowledge of language. Social communication skills are essential for connecting and engaging with others, and SC deficits are often associated with emotional and behavioral problems. There is a lack of feasible instruments for assessing SC skills in individuals with intellectual disability (ID).Methods: A questionnaire on social communication in adults with ID (QSC-ID) comprising 20 Likert-scaled items was developed and completed on behalf of participants (n = 52) from three Austrian therapeutic living communities for people with ID and deafness by their living- and working-facility key caregivers. The sample of adults with hearing loss was considered ideal for the development of a measure of SC that is not restricted to a specific communication mode or overly related with language skills.Results: The preliminary results showed high construct validity. Correlations were high between SC and language, social skills, and severity of autism spectrum disorder (ASD), moderate between SC and adaptive skills, and non-verbal intelligence and, as expected, low between SC and motor skills. Interrater reliability was found to be good or at least acceptable for all items. Total raw scores were well-distributed over the whole range—Cut-offs based on the 10th and 20th percentile are suggested to identify atypical and borderline SC skills. Caregiver feedback and completeness of data suggest that the questionnaire is highly feasible.Conclusion: Questionnaire on social communication in adults with ID is an easy-to-use caregiver-reported questionnaire for use with individuals with mild to severe forms of ID. Initial testing of validity looks promising. Further validation in populations with typical hearing is required. Due to substantial correlations between SC and structural language skills the calculation of specific SC cut-offs for different levels of linguistic skills should be considered when sufficient data is available.

Agreement Between Parental Report and Clinician Observation of Infant Developmental Skills.

Understanding the convergence between parent report and clinician observation measures of development is important and became even more critical during the COVID-19 pandemic as clinician contact with families was significantly limited. Previous research points to inconsistencies in the degree of agreement between parents and clinicians and very little research has examined these associations for infants within the first year of life. This study investigated the association between parent report and clinician observation measures of social communication and motor skills in 27 young infants who were assessed at 9 and 12 months of age. Results suggest a strong relation between clinician and parent rated motor skills, but weak to moderate associations between clinician and parent rated communication skills. Infant temperament played a significant role in parent ratings of infant communication. Together, these results provide support for data collection via parent report or clinician observation of infant motor skills, but suggest that multiple measures of infant communication may be helpful to obtain high-quality, perhaps more accurate, assessment social-communication skills. Specifically, multiple parent report measures along with an observation of parent-infant interactions will likely provide a more rich and accurate characterization of infant social-communication abilities.

Psychometrics of the Pragmatic Rating Scale for School-Age Children With a Range of Linguistic and Social Communication Skills.

Purpose Social communication or pragmatic skills are continuously distributed in the general population. Impairment in these skills is associated with two clinical disorders, autism spectrum disorder (ASD) and social (pragmatic) communication disorder. Such impairment can impact a child's peer acceptance, school performance, and current and later mental health. Valid, reliable, examiner-rated observational measures of social communication from a semistructured language sample are needed to detect social communication impairment. We evaluated the psychometrics of an examiner-rated measure of social (pragmatic) communication, the Pragmatic Rating Scale-School Age (PRS-SA). Method The analytic sample consisted of 130 children, ages 7-12 years, from five mutually exclusive groups: ASD (n = 25), language concern (LC; n = 5), ASD + LC (n = 10), social communication impairment only (n = 22), and typically developing (TD; n = 68). All children received language and autism assessments. The PRS-SA was rated separately using video-recorded communication samples from the Autism Diagnostic Observation Schedule. Assessment data were employed to evaluate the psychometrics of the PRS-SA. Analysis of covariance models were used to assess whether the PRS-SA would detect differences in social communication functioning across the five groups. Results The PRS-SA demonstrated strong internal reliability, concurrent validity, and interrater reliability. PRS-SA scores were significantly higher in all groups compared to the TD group and differed significantly in most pairwise comparisons; the ASD + LC group had the highest (more atypical) scores. Conclusions The PRS-SA shows promise as a measure of social communication skills in school-age verbally fluent children with a range of social and language abilities. More research is needed with a larger sample, including a wider age range and geographical diversity, to replicate findings. Supplemental Material https://doi.org/10.23641/asha.15138240.

The First Years Inventory (FYI 3.1): Structure as a Measure of Sensory Regulation and Social Communication in Children Between 6 and 18 Months

Abstract Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations. This paper tests the structure of the First Years Inventory (FYI 3.1), a measure of social communication (SC) and sensory regulation (SR) and whether the structure varies over age; data collection was done on a community sample of 1,893 children between 8 and 16 months old. Results provided support for eight factors, three SC and five SR. There is evidence that the overall structure holds over the range of ages assessed, with some variability in factor loadings and between-factor correlations.

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

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.

Rate of Communicative Gestures and Developmental Outcomes in Toddlers With and Without Autism Spectrum Disorder During a Home Observation.

PurposeMost toddlers with autism spectrum disorder and other developmental delays receive early intervention at home and may not participate in a clinic-based communication evaluation. However, there is limited research that has prospectively examined communication in very young children with and without autism in a home-based setting. This study used granular observational coding to document the communicative acts performed by toddlers with autism, developmental delay, and typical development in the home environment.MethodChildren were selected from the archival database of the FIRST WORDS Project (N = 211). At approximately 20 months of age, each child participated in everyday activities with a caregiver during an hour-long, video-recorded, naturalistic home observation. Inventories of unique gestures, rates per minute, and proportions of types of communicative acts and communicative functions were coded and compared using a one-way analysis of variance. Concurrent and prospective relationships between rate of communication and measures of social communication, language development, and autism symptoms were examined.ResultsA total of 40,738 communicative acts were coded. Children with autism, developmental delay, and typical development used eight, nine, and 12 unique gestures on average, respectively. Children with autism used deictic gestures, vocalizations, and communicative acts for behavior regulation at significantly lower rates than the other groups. Statistically significant correlations were observed between rate of communication and several outcome measures.ConclusionObservation of social communication in the natural environment may improve early identification of children with autism and communication delays, complement clinic-based assessments, and provide useful information about a child's social communication profile and the family's preferred activities and intervention priorities.Supplemental Material https://doi.org/10.23641/asha.14204522
