People diagnosed with autism spectrum disorder (ASD) deserve the same respect as any other person and should be free to benefit from scientific research that can help them achieve skills which enable them to reach their full potential. Over the past 40 years Applied Behaviour Analysis (ABA) has utilised inductive, natural science methods to…

Although, recent reviews and outcome research support empirical evidence for Early Intensive Behavior Intervention in University and community settings, research has also indicated that not all intensive behavioral service provisions are equally effective. Therefore, it was necessary to comprehend key variables that are common to empirically…

This study reports on predictors of outcome in 332 children, aged 2-7 years, enrolled in the community-based Intensive Behavioral Intervention (IBI) program in Ontario, Canada. Data documenting children's progress were reported in an earlier publication (Perry et al., 2008). The present paper explores the degree to which four predictors (measured…

This study examined the previous and current range of educational, therapy, medical and CAM interventions used by a clearly described Australian sample of 84 families of preschool-aged children with autism spectrum disorders who were enrolled in a controlled trial of early intervention services. With regard to educational and therapy…

The aim of this study was to identify risk factors for the occurrence of challenging behavior along with the specific topographies of challenging behavior shown by a sample of children with autism spectrum disorder in Ireland. The occurrence of challenging behavior was examined in comparison with the following variables: gender, age, level of…

The current study evaluated risk factors for the occurrence, frequency and severity of challenging behavior among a sample of individuals with a diagnosis of autism, under the age of eighteen, in Ireland. Age, gender, hours of intervention received, age at diagnosis, presence of challenging behavior at diagnosis and treatment type at diagnosis…

This study explored the best predictors of the progress of children with autistic spectrum disorders (ASD), on some developmental domains (autistic severity, language, communication and socialisation), which are related to the core features of ASD. Eighty-six children (2.5-14 years old) with ASD, from 10 schools in Greece, were included in the…

Although the "efficacy" of Intensive Behavioral Intervention (IBI) for young children with Autism Spectrum Disorders (ASD) has been well documented in small model programs, IBI's "effectiveness" (i.e., does it work in the "real world"?) has been less studied and may not be as impressive, e.g. Bibby, Eikeseth, Martin,…
