One-hundred nine children 3-16 years of age diagnosed with Autistic Disorder, Pervasive Developmental Disorder Not Otherwise Specified, or Asperger's Syndrome were studied. Children resided in six states in the United States. Using moderation analysis via multiple regression, verbal communication and challenging behaviors and how they interact…

Although intense fears have been reported in up to 64% of children with an autism spectrum disorder (ASD), little is known about the phenomenology of fear in this population. This study assessed the relationship between fear and core symptoms of autism in children with an ASD. In Phase I of this study, parents of 41 children with an ASD completed…

Early identification of autism spectrum disorders (ASDs) is facilitated by the use of standardized screening scales that assess the social emotional behaviors associated with ASD. Authors examined accuracy of Brief Infant-Toddler Social and Emotional Assessment (BITSEA) subscales in detecting Modified Checklist for Autism in Toddlers (M-CHAT) risk…

There is a paucity of evidence concerning the patterns of multi-informant agreement in populations with Autism Spectrum Disorders (ASD). This study compared ratings of behaviour and emotional problems and social functioning provided by 45 adolescents aged 12-18 years, with Autistic or Asperger's Disorder with ratings by their parents and teachers.…

Multiple sleep problems have been reported in children with Autism Spectrum Disorder (ASD). The association of poor sleep with problematic daytime behaviors has been shown in small studies of younger children. We assessed the relationship between sleep and behavior in 1784 children, ages 2-18, with confirmed diagnosis of ASD participating in the…

There is very little known about how sibling characteristics may influence the social functioning of a child with an autism spectrum disorder (ASD). The current study utilized data from the Simons Simplex Collection (SSC; n=1355 children with ASD and 1351 siblings) to investigate this relationship. Phenotypic measures included (a) the "Autism…

Autism has become one of the most heavily researched topics in the field of mental health and education. While genetics has been the most studied of all topics, applied behavior analysis (ABA) has also received a great deal of attention, and has arguably yielded the most promising results of any research area to date. The current paper provides a…

Autism Spectrum Disorder (ASD) is a neurodevelopmental disability characterized by deficits in social interaction and communication and by repetitive behaviors and restricted interests. Prior research has revealed executive function (EF) deficits in children with ASD. It has been suggested that these EF impairments are associated with language…

Children with autism spectrum disorder (ASD) have particular difficulty with behavioral flexibility, but the knowledge base on behavioral flexibility in children with a diagnosis of ASD plus intellectual disability (ID) compared to children with ID only is still scarce. The aim of the present study was to assess behavioral flexibility in 111…

The relationship between social deficits and challenging behaviors were studied in adults with severe intellectual disability (ID) and autism spectrum disorders (ASD). These issues are of paramount importance because they are core features for persons with these disabilities, and markedly effect normal adjustment and community integration. To…

Symptoms of repetitive, obsessive and compulsive behaviour were explored in a group of adolescents and young adults with Asperger syndrome and compared to a typically developing group. By means of self-evaluations and an interview regarding such symptoms with the adolescents and young adults and parental evaluations, the parents retrospectively…

To determine maternal stress and child variables predicting maternal stress, 104 mothers of children with autism spectrum disorder (ASD) and intellectual disability (ID) completed the Dutch version of the Parental Stress Index (PSI; De Brock, Vermulst, Gerris, & Abidin, 1992) every six months over a period of two years. The level of maternal…

Deficits in social skills are characteristic of children with autism. Clinicians often include teaching these skills as part of comprehensive curriculum. One method of developing social skills for children with autism is the teaching interaction procedure. This procedure involves describing the behavior, providing a rational and cues when to use…

Autism Spectrum Disorders (ASD) are a group of neurodevelopmental disorders characterized by deficits in socialization, communication, and restricted interests and repetitive behaviors. In addition to these core deficits, individuals with ASD also experience co-occurring conditions such as problem behaviors. Problem behaviors are common to this…

Although early recognition of autism spectrum disorder (ASD) is important, the age of children at diagnosis is variable. Forty-five participants diagnosed with ASD were divided into groups based on age at diagnosis and compared on age when parents first became concerned about various aspects of their development. Results demonstrated no…
