Children with autism often demonstrate disruptive behaviors during demanding teaching tasks. Language intervention can be particularly difficult as it involves social and communicative areas, which are challenging for this population. The purpose of this study was to compare two intervention conditions, a naturalistic approach, Pivotal Response…

Early intervention for autism spectrum disorder (ASD) tends to focus on enhancing social-communication skills. We report the acceptability, feasibility and impact on child functioning of a new 8 weeks parent-group intervention to manage restricted and repetitive behaviours (RRB) in young children with ASD aged 3-7 years. Forty-five families took…

A network conceptualization might contribute to understanding the occurrence and interacting nature of behavioral traits in the autism realm. Networks were constructed based on correlations of item scores of the Autism Diagnostic Observation Schedule for Modules 1, 2 and 3 obtained for a group of 477 Dutch individuals with developmental disorders.…

Autism spectrum disorders (ASD) are characterized by difficulties with social interaction, verbal and nonverbal communication, and the development and maintenance of interpersonal relationships. As a result, individuals with ASD are at an increased risk of bullying victimization, compared to typically developing peers. This paper reviews the…

This paper presents an overview of 5 meta-analyses of early intensive behavioral intervention (EIBI) for young children with autism spectrum disorders (ASDs) published in 2009 and 2010. There were many differences between meta-analyses, leading to different estimates of effect and overall conclusions. The weighted mean effect sizes across…

Characteristics of autism research were examined in the survey of a subset of studies (1971-1982). Results indicated inadequacies of subject selection procedures and omission of important descriptive information. The authors stress the need for increased use of objective, quantitative measures of diagnosis and assessment of intellectual abilities.…

This paper reviews the methodology in articles that have reported structural neuroimaging or neuropsychological data in adolescent patients with schizophrenia. Identification of methodological issues led to the finding that, at present, no conclusions can be made regarding the presence or absence of neuropsychologic dysfunction or structural…

There has been much research concerning functional assessment over the past 20 years, but several important research considerations have yet to be explained. One is the comparison of different types of functional assessment (e.g., experimental functional analysis and non-experimental functional assessment). The current study aims to compare the…

Several different methodological approaches that have been used in studying language in children with autism are outlined. In classic studies, children with autism are compared to comparison groups typically matched on age, IQ, or mental age in order to identify which aspects of language are uniquely impaired in autism. Several methodological…

The possibility of differential sex proportions as a confounding factor in the Lovaas (1987) study is raised. It is argued that the chi-square analysis was inadequate and that the appropriate comparison should be made between the experimental and the control group using population data to estimate expected cell frequencies.
