Autistic disorder and pervasive developmental disorder-not otherwise specified (PDD-NOS) are types of Autism Spectrum Disorders (ASDs) characterized by social deficits, communication impairments, as well as stereotyped and repetitive interests and behaviors (Matson, 2007a, 2007b; Matson, Matson, & Rivet, 2007a). Although motor impairments are not a core(More)
BACKGROUND The Autism Spectrum Disorder Observation for Children (ASD-OC) is a new observation scale used to assess autistic symptomatology. As the publication of the fifth edition Diagnostic and Statistical Manual (DSM) is approaching, exploring the effect of the changing DSM criteria has begun to occur. OBJECTIVE The aim of this study was to compare(More)
OBJECTIVE To provide an overview and critical assessment of common problems and best evidence practice in treatments for the challenging behaviours (CBs) of adults with intellectual disabilities (IDs). METHOD Commonly observed problems that present obstacles to successful treatment plans are discussed, followed by an analysis of available research on the(More)
PURPOSE Autism Spectrum Disorders (ASD) and seizures are highly comorbid conditions. However, little research has been done to examine this relationship. The purpose of the current study was to examine the effect that seizure disorder has on symptom presentation in children with autism spectrum disorders as compared to atypically developing children.

OBJECTIVE The aim of the current study was to examine the effects of symptom severity of ASD and symptom severity of inattention and impulsivity in toddlers to determine the potential impact on social skills. METHODS A total of 240 toddlers diagnosed with ASD, ranging in age from 17-36 months, were included in this study. Parents or legal guardians were(More)
OBJECTIVE Investigations about first concerns among parents of toddlers with ASD and comparisons of the same with children diagnosed with other developmental disorders are scarce. METHOD The current study utilized a sample of toddlers diagnosed with an ASD or other developmental delay and examined the nature of parents' first concern and the age of first(More)
OBJECTIVE The diagnostic stability of Autism Spectrum Disorders (ASD) at very young ages continues to be debated, despite empirical evidence that ASDs can be reliably diagnosed in children under the age of 3 years. This topic is of the upmost importance given that early intervention increases long-term outcomes in this population. METHODS The goal of the(More)
PURPOSE Autism Spectrum Disorders (ASD) are a group of conditions characterized by symptoms that onset in early childhood. Deficits in social skills and communication are two of the core features of ASD and, if not remediated, can lead to poor long-term outcomes. Few researchers have examined characteristics of social skills and communication in infants(More)
PURPOSE To run a discriminant analysis on the individual items and the total scale of the ASD-OC to determine if they significantly discriminated between ASD and atypical groups. METHOD The measure was administered to 78 children as part of an outpatient evaluation. RESULTS The DA revealed that all of the items, excluding five, were significant(More)
OBJECTIVE Best assessment practices for Autism Spectrum Disorders (ASD) incorporate both multimodal and multi-informant assessments. However, differences in symptoms reports from multiple informants can lead to diagnostic decision-making problems. METHODS Thus, the purpose of this paper was to examine differences in the reports of symptoms of ASD between(More)
