Background Rhythmic Relating is an approach to supporting social timing in therapeutic play with autistic children (Daniel, Laurie and Delafield‐Butt, 2024) and can be used as a stand‐alone approach or to augment child‐centered therapies. Aims A combination of Child‐Centered Play Therapy and Rhythmic Relating is evaluated in its therapeutic potent...

Background The UCLA PEERS program has been studied using predominantly White and affluent populations. As autistic teens and their parents are represented across cultures, it is vitally important that interventions are tailored to their needs–whether that be linguistically or with respect to their cultural practices. Thus, the current qualitative s...

Background: Classrooms can create barriers to young autistic students' social and behavioral success at school. Better quality student-teacher relationships (STRs) have been associated with improved student social and behavioral outcomes. When teachers use more positive response strategies (e.g., praise), they create more opportunities for positive...

Emotion Regulation is a key factor in the psychological well‐being of children on the autism spectrum. Therapeutic co‐regulation is posited here as fundamental to addressing Emotion Regulation needs. A therapeutic combination of Child‐Centred Play Therapy and Rhythmic Relating is assessed in its potential to improve Emotion Regulation outcomes (ove...

Autistic students experience greater social difficulties and heightened internalizing behaviors (e.g., anxiety, depression, withdrawal) relative to their nonautistic peers, yet little is known about how these domains influence one another over time. This 1.5-year longitudinal study analyzed the associations between teacher-reported social skills an...

Purpose: Comparative data of autism-sensitive standardized measures of emotion regulation and lability, describing percentage change over time for populations of young autistic children, are currently publicly unavailable. We propose publication of such data as a support for future therapeutic intervention studies. Methods: We generate and prese...

Thirteen autistic teens, who were predominantly Latinx, completed the Program for the Education and Enrichment of Relational Skills (PEERS), a 16‐week social skills intervention. Time‐frequency decomposition was calculated using advanced electroencephalographic techniques to measure oscillatory brain activity during reward anticipation and processi...

Introduction During the early beginnings of COVID-19, service providers were forced to close their doors and move their services online, causing significant disruptions for many families and communities, such as those with intellectual and developmental disabilities (IDD). In this study, we examined the extent to which COVID-19 disrupted services f...

Parent-teacher relationship (PTR) quality is linked to child and family-school functioning and may be especially important in the school adjustment of autistic children. However, measurement of PTR quality has been limited by inconsistency in the use of measures, a paucity of two-informant measurement, and limited psychometric consideration. We exa...

Background: Student academic behavioral engagement (BE) contributes to learning and school success. Student-teacher relationships (STRs) may promote BE, although previous findings regarding how these constructs are associated over time are mixed. For young autistic students who face barriers to early school success, a high-quality STR may serve as...

Background: School is an important context for identity development across childhood and adolescence. These formative experiences impact adulthood. Minimal research has examined first-person autistic perspectives of how school experiences shape autistic identity as well as other intersecting identities. In this study, we examined the school messag...

To identify target areas for professional development, this mixed-methods study examined general education teachers’ perceptions of autism and pedagogical practices in early elementary classrooms in the United States. In focus groups, teachers ( N = 18) identified terms they associated with autism and strategies they used for inclusion and relation...

Each chapter focuses on the similarities and differences between ASD and a second diagnosis. For example, one chapter outlines clinical co...

Viewed through a social justice lens, preschool expulsion is an educational equity issue. This study focused on prior expulsion from preschool and child-care in a longitudinal study of 203 autistic children, ages 4 to 7. By parent report, 16%—one out of six autistic children—had been expelled from a preschool or child-care setting prior to elementa...

Autistic students often experience peer relationship difficulties. As peer acceptance and rejection may be malleable over time, we examined predictors of change in peer acceptance and peer rejection among early elementary‐age autistic students. We followed 166 autistic children (mean age: 6.1 years [range: 4–8], 82.5% boys, grades preK‐2nd) longitu...

Objectives Hope is reliably associated with positive outcomes in youth; however, prior literature has yet to explore hope in neurodiverse individuals. As adolescents with neurodevelopmental differences (ND) display distinct neurocognitive profiles and are at risk for poor psychosocial outcomes, it is essential to understand how this marginalized gr...

Early elementary students on the autism spectrum are at risk for poor quality student-teacher relationships (STRs), a key contributor to student outcomes. However, these students' own appraisals of their STRs are nearly absent from the literature. This study examined children's perspectives of STRs and agreement with teacher-reported STRs for a sam...

Due to the coronavirus disease 2019 (COVID‐19) pandemic, the importance of telehealth has rapidly increased, in particular as many in‐person clinics have closed. Early intervention is crucial for improving outcomes in children with autism spectrum disorder (ASD). As such, the need for timely assessments and diagnoses remains despite COVID‐19‐relate...

The Program for the Education and Enrichment of Relational Skills (PEERS) social skills intervention has demonstrated effectiveness for adolescents with autism spectrum disorder (ASD). However, studies have been limited by a lack of objective outcome measures and an underrepresentation of Latinx families. This pilot study extends the PEERS literatu...

Background Considering the COVID-19 pandemic, understanding the reliability, validity, social validity, and feasibility of using telehealth to diagnose ASD is a critical public health issue. This paper examines evidence supporting the use of telehealth methods to diagnose ASD and outlines the necessary modifications and adaptations to support teleh...

Background: The Social Motivation Hypothesis proposes that individuals with autism spectrum disorder (ASD) experience social interactions as less rewarding than their neurotypical (TD) peers, which may lead to reduced social initiation. Existing studies of the brain's reward system in individuals with ASD report varied findings for anticipation of...

Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the Autism Diagnostic Observation Schedule—Second Edition, includes three items (“E-codes”) for EBPs that are frequently associated with ASD. Few empirical...

Limited research has explored mothers’ perceptions of teachers’ pedagogical practices that may or may not support the learning and development of their child with autism spectrum disorder (ASD). Mothers of children with ASD were asked to describe their perspective regarding three questions: (1) How do teachers structure the classroom environment to...

Objective: Transition from school to early adulthood incurs many changes and may be associated with deterioration in general health in youth with autism. We aimed to investigate this. Method: The National Longitudinal Transitions Study-2 is a USA nationally representative sample of youth receiving special education services, aged 13–17 at wave 1, f...

Purpose Professionals working with community populations are often presented with complicated cases where it is difficult to determine which diagnosis or diagnoses are appropriate. Differentiating among neurodevelopmental disorders such as autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder and intellectual disability can be a...

ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children’s behavior problems may provide clinically relevant information. We examined parent–teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the...

Background: Challenges in adaptive behaviors are present in individuals with autism spectrum disorder (ASD), while variation in IQ, social skills, and comorbidities are possible influences on adaptive behaviors. However, adaptive behaviors do not consistently map onto cognitive abilities in ASD, as high IQ is not protective against challenges in ad...

Emerging research suggests that caregiving environments and genetic variants independently contribute to social functioning in children with typical development or autism spectrum disorder (ASD). However, biologically plausible interactive models and complimentary assessment of mechanisms are needed to: (a) explain considerable social heterogeneity...

Background: Teenage youth with co-morbid intellectual disability (ID) and autism spectrum disorder (ASD) could be at higher risk for behavioral and social difficulties than youth with ID only. Methods: Youth aged 13 years were diagnosed with ID (n = 37), ID/ASD (n = 26), or typical development (TD, n = 98). Mothers and teachers completed measures o...

Background There has been little prior investigation of the general health of young people with intellectual disabilities across transition, nor separately for youth with intellectual disabilities with or without Down syndrome, despite general health being a strong predictor of subsequent health service use, hospital admissions and mortality in th...

The transition to school can be difficult for any child, but children with autism spectrum disorder (ASD) encounter additional problems and obstacles during this time. ASD is a lifelong disorder. Yet, the earlier a child with ASD receives intervention, the more promising the long-term outcomes. One way for children to be identified with ASD before...

The reward system has been implicated as a potential neural mechanism underlying social-communication deficits in individuals with autism spectrum disorder (ASD). However, it remains unclear whether the neural reward system in ASD is sensitive to behavioral interventions. The current study measured the reward positivity (RewP) in response to social...

This study examined the prevalence of ADHD symptoms and anxiety as reported by parents and teachers for 180 preschool children (ages 4–5) and school-aged children (ages 6–7) with ASD using the Child Behavior Checklist—Parent and Teacher Report Forms (Achenbach and Rescorla, Manual for ASEBA school-age forms & profiles, Research Center for Children,...

The language and social skill deficits associated with autism spectrum disorder (ASD) warrant further study. Existing research has focused on the contributions of pragmatic language to social skills, with little attention to other aspects of language. We examined the associations across three language domains (semantics, syntax, and pragmatics) and...

There is minimal research regarding the personal experiences and perceptions of youth with autism spectrum disorder (ASD). Yet, the positive and negative perceptions that youth internalize about their diagnoses are crucial, as they may have a strong impact on individuals’ self-concept and well-being. This paper utilizes mixed methods to describe th...

Background: The successful inclusion of youth with autism spectrum disorder (ASD) in neuroimaging research is imperative for advancing our understanding of the neurobiological underpinnings of ASD. In order to generate knowledge that is representative of all affected youth, it is essential to include participants who are culturally and linguistical...

Purpose Historically, children with autism spectrum disorder (ASD) were sometimes diagnosed with schizophrenia or major psychosis. Although significant advancements in the process of differential diagnosis have been made since 1950s, there still exists a problematic delay in diagnosis due to overlap of symptoms. Negative symptoms of schizophrenia c...

Introduction: We examined the development of anxiety in youth with or without intellectual disabilities (ID). We also examined the effects of child delay status, temperament, ethnicity, and negative parenting on anxiety symptom trajectory. Method: Participants were 177 families in (blinded). We employed latent growth curve modeling to examine the t...

Student–teacher relationship (STR) quality during the early school years has important implications for student adjustment and outcomes. Studies with typically developing (TD) children have identified links between parent behaviors and STRs, but these connections remain unexplored for children with autism spectrum disorder (ASD). The present study...

In an evaluation of Anglo and Latina mothers and their children at risk of autism, this study compared mother-reported child behavioral concerns to staff-observed symptoms of autism. Within Latina mothers, the impact of primary language (English/Spanish), mothers’ education, and child age on ratings of developmental concerns was examined. Participa...

Children with autism spectrum disorder (ASD) vary greatly in social functioning, and in turn, long-term relational and academic outcomes. Responsive parenting which follows a child’s lead and focus of attention is predictive of language and social gains for children with or without developmental risk. The present study prospectively assessed 176 fa...

Disruptive behavior disorders were assessed in 160 youth aged 13 years, with Autism Spectrum Disorder (ASD, n = 48), intellectual disability (ID, n = 28), or typical development (TD, n = 84). Mothers’ reported collateral effects on their psychological adjustment were related to both youth disability status and clinical level behavior disorders. Mor...

This chapter reviews educational strategies and legal policies impacting effective schooling for children, youth, and young adults. Emphasis is on the classroom manifestation of autism spectrum disorder (ASD), and how general education teachers can effectively facilitate learning. Within early school years, the importance of positive student-teache...

Background and aims: High quality student-teacher relationships (STR) are important for children's academic and social development. We explore how individual child language domains (semantics, syntax, pragmatics), teacher years of experience, and classroom placement (general or special education) relate to STR quality for children with autism spec...

Increasingly, young adults with autism spectrum disorder are attending 4-year universities. The transition to adulthood can be challenging for these students, and university life poses its own set of demands. The present article takes a mixed-methods approach by including two studies utilizing complementary methodologies. Through in-depth interview...

Disruptive behavior disorders and social skills were assessed in 187 youth aged 13 years, with typical cognitive development (TD n = 98), intellectual disability (ID n = 37), autism spectrum disorder (ASD, IQ > = 85, n = 26), or Autism Spectrum Disorder with ID (ASD/ID; IQ < 85, n = 26). The primary question was whether youth with ASD and co-morbid...

Relatively limited research has been devoted to understanding the postsecondary experience from the students’ perspectives. In the current study, individual interviews were conducted with university students with autism spectrum disorder (n = 13) and students with Attention Deficit/Hyperactivity Disorder (n = 18) to investigate likely factors imped...

Relationships between early literacy measures (i.e., curriculum-based measurement) and advanced literacy measures (i.e., reading comprehension) were examined in young children with autism spectrum disorders (ASDs). Participants in this study were 167 children between the ages of 4 and 7 years ( M = 5 years 8 months), who were assessed at 2 time poi...

Background: It is known that children with disabilities, especially adolescents with autism spectrum disorder (ASD), are at increased risk for victimization. However, little is known about the impact of victimization over time. Aims: Primary aims included identifying to what extent risk factors (i.e., internalizing behavior problems and conflict...

Autism spectrum disorder (ASD) is estimated to affect one in 68 children. Given the increase in both prevalence and awareness of ASD, it is critical to provide accurate and timely diagnosis. However, ASD often co-occurs with other disorders, making diagnosis difficult. The objective of the current case study was to provide two examples of different...

Background Despite studies of how parent–child interactions relate to early child language development, few have examined the continued contribution of parenting to more complex language skills through the preschool years. The current study explored how positive and negative parenting behaviours relate to growth in complex syntax learning from chil...

It has been well documented that individuals with autism spectrum disorder or intellectual disabilities demonstrate comorbid behavior problems, or behaviors that are not specified by the criteria for the diagnosis. Co-occurring behavior problems can substantially interfere with the child's educational and social functioning, lead to poor long-term...

We examined parents’ satisfaction with multiple aspects of their children’s individualized education programs (IEPs). Parents (n = 142) raising children ages 4 to 8 years old with autism spectrum disorder (ASD) reported their satisfaction with four aspects of their children’s IEPs: (a) content of the IEP document, (b) services provided, (c) perceiv...

Among typically developing children, many characteristics have been associated with parents' expectations for their children's adjustment to school and academic progress. Despite the history of increased parental involvement in the education of children with autism spectrum disorder (ASD) relative to parents of children without ASD, there is little...

Children with autism spectrum disorder (ASD) are at heightened risk for developing comorbid psychological disorders, including anxiety disorders, which may be further exacerbated by the presence of externalizing behaviors. Here, we examined how structural language and pragmatic language predicted anxiety and externalizing behaviors. Participants we...

This study identified trajectories of depressive symptoms among mothers of children with or without intellectual disability longitudinally across eight time points. Results of fitting a linear growth model to the data from child ages 3–9 indicated that child behavior problems, negative financial impact, and low dispositional optimism all significan...

Individual differences in emotion regulation are central to social, academic, occupational, and psychological development, and emotion dysregulation (ED) in childhood is a risk factor for numerous developmental outcomes. The present study aimed to (a) describe the developmental trajectory of ED across early childhood (3–6 years) and (b) examine its...

Though ethnic and racial disparities have been reported in both diagnosis and treatment of mental health disorders, few studies have explored potential differences in how parents of varying cultural backgrounds perceive symptoms of autism spectrum disorder (ASD). Most have relied on hypotheses of socioeconomic and access barriers to explain finding...

Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent...

There has been little research connecting underlying emotion processes (e.g., emotion regulation) to frequent behavior problems in young children with autism spectrum disorder (ASD). This study examined the stability of emotion regulation and its relationship with other aspects of child functioning. Participants included 108 children with ASD, ages...

The purpose of this study was to identify how parents’ use of language and literacy strategies during an adapted shared book reading activity relate to social, behavioral, and cognitive skills for their children with autism spectrum disorder (ASD). Participants were 111 young children (ages 4–7 years) with ASD and their mothers. A factor analysis o...

The quality of early student-teacher relationships (STRs) has been shown to predict children's school adjustment, and children with autism spectrum disorder (ASD) are at risk for poor quality STRs. The present study examined 162 children with ASD (ages 4-7) and their teachers to evaluate student, teacher, and classroom characteristics that predicte...

Background Having a child with intellectual disability impacts all family members, with both parents and siblings having to adjust. Negative impact on the typically developing sibling, specifically, has been shown to vary based on caregiving responsibilities and mothers? stress level. Method This study gathered information from 238 Latina and Anglo...

The study of the impact of children or youth with intellectual and developmental disabilities on their families has grown increasingly complex. This is due, in part, to the multiple perspectives represented in research (e.g., mothers, fathers, siblings) and to the myriad of outcomes examined (e.g., negative vs. positive impact on families). Basic t...

Youth with autism spectrum disorder (ASD) present with an array of deficits in social interactions, as well as with manifestations of problem behaviors. Despite the significant challenges that these diagnostic features can create for an individual’s personal and academic development, many youth with high-functioning ASD are testing their independen...

Self-and professor-perspectives of college experiences among university students with ASD/ADHD

Previous research of parents and children with ASD found that with greater severity of child behavior problems, parents are more likely to experience greater psychological distress and to develop mental health issues, such as anxiety and depression (Hastings & Brown, 2002; Hodapp et al., 1997). In fact, mothers of children with ASD are more likely...

Background: Researchers have primarily relied on mother report to understand the parenting contexts of rearing children with intellectual disabilities. Fathers are increasingly being considered as equally important reporters of their child's behaviours, as they have unique and independent relationships with their children. The purpose of this stud...

Perceived loneliness and social competence were assessed for 127 children with ASD without comorbid ID, 4-7 years old, through child self-report. Using an abbreviated version of the Loneliness and Social Dissatisfaction Questionnaire (LSDQ; Cassidy and Asher in Child Dev 63:250-365, 1992), the majority of children reported friendships, yet a consid...

Although young adults with Autism Spectrum Disorder (ASD) are increasingly attending college, many fall short of graduating (Shattuck et al., 2012). The purpose of this study is to investigate the factors impeding graduation, a metric for academic success, in youth with ASD. Ten undergraduate/graduate students were interviewed about their experienc...

In this conceptual article, we integrate existing literature on early school transitions, ecological systems theory, and student-teacher relationships to propose a framework for investigating the transition to school for children with autism spectrum disorders (ASD).A review of the literature suggests that the quality of early student-teacher relat...

This study explores accurate conceptualization of the adaptation construct in families of children with developmental delay aged 3 to 8 years. Parents' self-reported measures of adaptation and observed dyadic relationship variables were examined. Confirmatory factor analysis and longitudinal growth modeling were used to evaluate the nature of adapt...

Dual diagnosis of autism spectrum disorder (ASD) and behavior problems and/or mental disorders has become increasingly recognized and studied. Reported rates in samples of mixed-age youth with ASD are often above 70%, making this comorbidity more the rule than the exception. The present study compared rates of disruptive behavior disorder diagnosis...

It is widely acknowledged that mothers of children with intellectual and developmental disabilities (IDD) experience increased levels of stress and depression when compared with mothers of typically developing children. In cross-sectional work addressing the relationship between child behavior problems and maternal depression, it is more often the...

Professional schools are responsible for training students in how to deliver high-quality services equitably to diverse families. This chapter describes the role of educational professionals in meeting the needs of diverse families who have children with autism and the training process needed to prepare them. We set the stage by presenting an overv...

Parenting research is frequently conducted without a thorough examination of socio-economic characteristics. In this study, longitudinal observations of positive parenting were conducted across six time points. Participants were 219 mothers of children with and without developmental delays. Mothers’ positive parenting increased during early and mid...

In-depth interviews conducted separately with 13-year-olds with autism spectrum disorder (ASD), intellectual disability (ID), or typical development (TD) and their mothers investigated the experiences of victimization in the form of bullying. Coded constructs from the interviews were utilized to compare groups on the frequency, type, and impact of...

Background: While tantrums, “meltdowns,” and other behavior problems have been studied extensively among children with autism spectrum disorders (ASD; e.g., Bauminger, Solomon, & Rogers, 2010; Mayes, et al., 2012), the underlying emotional dysregulation that often spurs these behavioral symptoms is not well understood. Furthermore, emotion dysregul...

Background: Little is known regarding the factors that affect student-teacher relationship (STR) quality in children with Autism Spectrum Disorder (ASD). However, positive STRs have been demonstrated to be important predictors of social, academic and behavioral outcomes in typical-developing populations (Hamre & Pianta, 2001). Few studies have exam...

This article provides direction for educational decision making specifically for individuals with autism spectrum disorder (ASD), who have the cognitive and adaptive capabilities required to pursue postsecondary college education. The purpose is to draw attention to the available postsecondary pathways, 2- and 4-year college options, by addressing...

There is a consensus that parenting a child with a developmental disorder can contribute to high levels of stress on the family (Eisenhower et al. 2005; Minnes 1998). The well-being of the parents can be compromised due to a number of factors (e.g., impact of the initial diagnosis, characteristics and behaviors associated with the disorder; Singer...
