At this point there is sufficient research to demonstrate the efficacy of Early Intensive Behavior Interventions (EIBI) for young children with autism spectrum disorders (ASDs). However, also of great importance is the value of these early efforts over time. The purpose of this review was to assess existing EIBI papers with respect to follow-up…

Functional assessment has now entered the mainstream for evaluation and to aid in the treatment of challenging behaviors, while experimental functional analysis was at the forefront of this movement, this particular methodology has proven to be impractical, and thus has limited utility in real world settings. As a result of these factors…

Psychopathology prior to the last four decades was generally viewed as a set of problems and disorders that did not occur in persons with intellectual disabilities (ID).

A preponderance of males with autism spectrum disorders (ASD) has been evident since the initial writings on the topic. This male predominance has consistently emerged in all ASD research to date in epidemiological as well as clinical populations. Despite this long recognized gender disparity in ASD, surprisingly there is a paucity of research…

One-hundred seventy-three studies that employed functional assessment were evaluated with respect to types of challenging behaviors studied and the functions identified that maintained those behaviors. For most studies, two to three behaviors were targeted. Of the 38 different challenging behaviors identified, self-injurious behavior (SIB) and…

An extensive literature on the causes of challenging behaviors has been developed, primarily in the applied behavior analysis literature. One hundred and seventy-three empirical studies were reviewed where functional assessment serves as the primary method of identifying these causes. Most of the studies were able to identify a clear function or…

Asperger's syndrome has gained tremendous recognition and popularity in the last 20 years. However, controversy around the nature of the disorder, whether it is distinct from high functioning autism, and whether it can be reliably and validly diagnosed has continued throughout this period unabated.

Great strides have been made in the development of skills and procedures to aid children with developmental disabilities to establish maximum independence and quality of life. Paramount among the treatment methods that have empirical support are treatments based on applied behavior analysis. These methods are often very labor intensive. Thus,…

Intellectual disability (ID) and autism spectrum disorders (ASDs) covary at very high rates. Similarly, greater severity of one of these two disorders appears to have effects on the other disorder on a host of factors. A good deal of research has appeared on the topic with respect to nosology, prevalence, adaptive functioning, challenging…
