Motor stereotypies are frequently reported in individuals with autism spectrum disorder, but determinants of stereotypies remain poorly understood. In this study, a randomized sample of children with diagnosis of autism spectrum disorder was investigated to identify the prevalence and determinants of stereotypies. A total of 134 children who…

Understanding the overlap of symptoms between oppositional defiant disorder (ODD) and obsessivecompulsive disorder (OCD) experienced by youth is pertinent for accurate diagnosis. A quantitative, retrospective, cross-sectional design format was used to assess the relationship between ODD and OCD in addition to evaluating the difference in ODD…

This study explored predictors of community-based providers' adherence to MATCH, a modular cognitive behavioral therapy for children and adolescents. Provider-reported adherence to MATCH was measured using three increasingly strict criteria: (1) "session content" (whether the session covered MATCH content consistent with the client's…

Autism is a lifelong condition characterized by repetitive and restrictive behaviors and differences in social communication. The reported prevalence of autism has risen exponentially in the past years. Early identification and subsequent early intervention are key to promoting better outcomes for autistic individuals. However, there is a dearth…

Verbal fluency tasks have been useful in characterizing the cognitive and language impairments in individuals with autism spectrum disorder (ASD). However, we have a limited understanding of verbal fluency in children and adolescents with comorbid ASD and attention-deficit/hyperactivity disorder (ADHD). The current study investigates whether the…

Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

Social communication and executive functioning challenges as well as co-occurring anxiety/depression may make acquiring the skills needed to manage daily life tasks difficult for diploma-track autistic youth, thus limiting their participation in adult roles. This study describes the associations between executive function, social communication…

Children and adolescents with Autism Spectrum Disorder (ASD) often show comorbid emotional and behavior problems. The aim of this longitudinal study is to examine the relation between emotion control (i.e., negative emotionality, emotion awareness, and worry/rumination) and the development of internalizing and externalizing problems. Boys with and…

High rates of attention deficit/hyperactivity disorder (ADHD) comorbidity have been described in autism spectrum disorder (ASD). This study searched for predictors at toddlerhood of the severity of ADHD symptoms at adolescence. The study included 65 participants, (mean age = 13:8 year), diagnosed with ASD at toddlerhood. Participants underwent a…

Many males with FXS meet criteria for ASD. This study was designed to (1) describe ASD symptoms in adolescent and young adult males with FXS (n = 44) and (2) evaluate the contributions to ASD severity of cognitive, language, and psychiatric factors, as well as FMRP (the protein deficient in FXS). A few ASD symptoms on the ADOS-2 were universal in…

The inclusion challenge of students with special educational needs does not end in the classroom. Mandatory community services in Israel may present unique challenges and supportive demands from their teachers. The goals of this study were to examine the risks experienced by youth with ADHD who joined rescue workers such as ambulance teams. The…

Adolescent risk-taking can potentially result in serious individual and societal consequences. Previous research demonstrates that emotional and behavioral problems, particularly externalizing behaviors, are significantly associated with an array of risky behaviors such as substance use, sexual behavior, injury, and violence. However, the…

Background: Among adolescents, depressive symptoms commonly co-occur with social anxiety, with social anxiety often developmentally preceding depressive symptoms. Thus, evidence-based assessments of adolescent social anxiety should be augmented with assessments of depressive symptoms using measures that can be administered across developmental…

The current study was a 7-year follow-up of 74 6-12 year old children with Pervasive Developmental Disorder-Not Otherwise Specified. We examined the rates and 7 year stability of comorbid psychiatric diagnoses as ascertained with the Diagnostic Interview Schedule for Children: Parent version at ages 6-12 and again at ages 12-20. Also, we examined…

Young people with autism spectrum disorder (ASD) have a high prevalence (~40 %) of anxiety disorders compared to their non-ASD peers. It is unclear whether cognitive and biological processes associated with anxiety in ASD are analogous to anxiety in typically developing (TD) populations. In this study 55 boys with ASD (34 with a co-occurring…
