Self-determination (SD) is linked to autonomy and better adult outcomes. Adults with autism spectrum disorder (ASD) are often less independent than cognitively matched peers. Given the frequency with which depression co-occurs in ASD and the established association between depression and SD, we sought to evaluate the influence of both ASD severity…

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…

Anxiety/obsessive-compulsive disorders are common among youth with autism spectrum disorder (ASD). Two versions of cognitive behavior therapy (CBT) are effective, with some advantage for a personalized, adapted version. This study evaluated predictors and moderators of standard CBT and adapted CBT. Youth (N = 167) ages 7-13 were randomized to…

Children with ASD are more likely to be involved in bullying compared to typically developing peers; however, studies rarely examine bullying perpetration and the contributing factors among this population. The primary aim of this study was to examine the extent to which parent-reported ASD symptoms, social skills, and comorbid externalizing and…

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…

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

We investigated the presentation and correlates of hoarding behaviors in 204 children aged 7-13 with autism spectrum disorder (ASD) and comorbid anxiety or obsessive-compulsive disorder (OCD) symptoms. Approximately 34% of the sample presented at least moderate levels, and with 7% presenting severe to extreme levels of hoarding. Child gender…

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…

Although executive functioning (EF) difficulties are well documented among children and adolescents with autism spectrum disorder (ASD), little is known about real-world measures of EF among adults with ASD. Therefore, this study examined parent-reported real-world EF problems among 35 adults with ASD without intellectual disability and their…

We examined co-occurrence of autism spectrum disorder (ASD) with (traits of) attention-deficit/hyperactivity (ADHD), obsessive-compulsive (OCD) and inhibition deficits in a community sample (n = 16,676) and tested whether having a sibling with ASD manifested in increased features of ADHD, OCD or inhibition deficits. Individuals with ASD had…

Samson et al. ("Journal of Autism and Developmental Disorders" 41:475-483, 2011) conducted the first empirical investigation examining the fear of being laughed at (gelotophobia) and its prevalence in individuals with high-functioning autism spectrum disorder (hfASD). The present research examined gelotophobia in relation to social…

The aim of this study was to explore the influence of parental intolerance of Uncertainty (IU), sensory sensitivity (SS) and Broader Autism Phenotype (BAP), as well as the severity of their children's autism symptoms and co-morbid symptoms, on the mental health of Chinese parents of children with autism spectrum disorder (ASD). One hundred 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…
