Purpose: Cross-informant ratings are considered best practice for assessing children with autism spectrum disorder (ASD). However, informant disagreement often occurs, which can pose significant challenges to various aspects of clinical services. This study explored the degree of parent and speech-language pathologist (SLP) agreement on ratings of…

While the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is considered a "reference standard" measure to observe symptoms of autism spectrum disorder (ASD), little is known about the utility of its Other Abnormal Behaviors or "E codes." This study investigated the unique influence of each E code (overactivity,…

For individuals with autism spectrum disorder (ASD) daily living skills (DLS) fall below chronological age and have been linked to factors such as language. Given the impact of DLS on daily life, it is critical to gain a comprehensive understanding of DLS profiles in children to guide effective treatment. Using a large dataset from the Autism…

Elevated parenting stress among parents of children with autism spectrum disorder is well-documented; however, there is limited information about variability in parenting stress and relationships with parent ratings of child functioning. The aim of this study was to explore profiles of parenting stress among 100 parents of young children with…

Autism spectrum disorder symptom emergence is heterogeneous, yet literature comparing young children diagnosed early versus later is relatively scant. Toddlers diagnosed with autism spectrum disorder between 12 and 18 months (n = 20), 19 and 24 months (n = 65), or 25 and 41 months (n = 27) were compared on demographics, developmental functioning,…

Children with autism spectrum disorder exhibit challenges in regulating negativity and modifying emotional responses, a process known as emotion regulation. Such challenges affect social outcomes and response to intervention in children with autism spectrum disorder. Caregivers of children with autism spectrum disorder facilitate children's…

This community effectiveness trial examined the feasibility and efficacy of a comprehensive psychosocial treatment for 28 children, aged 7 to 10 years with high-functioning autism spectrum disorders (HFASDs). Treatment included instruction and therapeutic activities targeting social skills, face-emotion recognition skills, interest expansion, and…

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…

Many children with autism spectrum disorder display challenging behaviors. These behaviors are not limited to those with cognitive and/or language impairments. The Collaborative and Proactive Solutions framework proposes that challenging behaviors result from an incompatibility between environmental demands and a child's "lagging…

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.…

Little is known about their stability and the factors that influence their persistence or change over the life-course. To address this, we use data from 158 participants from the Special Needs and Autism Project cohort studied at three time-points from 12 to 23 years. We used latent growth models to study the role of child, family, and contextual…

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,…

Parent-Child Interaction Therapy is an empirically based, behavioral parent training program for young children exhibiting disruptive behaviors. Parent--Child Interaction Therapy shows promise for treating disruptive behaviors in children with autism spectrum disorder. Treatment processes (i.e. treatment length and homework compliance), parenting…

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,…

This study aimed to assess physiological arousal and behavioral regulation of emotion in the context of frustration in 29 children with Autism Spectrum Disorders (ASD) and 45 typically developing children (41-81 months). Heart rate was continuously measured and emotion strategies were coded, during a locked-box task. Results revealed increases in…
