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.

Children with Autism Spectrum Disorders (ASDs) are well-known for engagement in challenging behaviors. Unfortunately, due to its absence as a criterion for diagnosis in the "DSM-IV-TR", little attention has been paid to the endorsement rates of such behaviors. However, a recently developed measure to assist in the diagnosis of infants and toddlers…

Pica is a very serious and often life threatening problem which occurs largely in persons with developmental disabilities. The topic has received sporadic attention from researchers for several decades. This paper reviews definitions, diagnostic implications, causes, prevalence, and assessment methods that have been described in the research…

A lack of toileting skills is one of many impairments that individuals with intellectual and developmental disabilities experience. Unfortunately, little research has focused on problems in this area including assessment, function, and treatment.

Autism spectrum disorders (ASD) and intellectual disabilities (ID) are high prevalence developmental disabilities that co-occur at high rates. Furthermore, Axis I psychopathology is known to occur more frequently in individuals with ID than the general population. The problems are lifelong and can be major impediments to independent living.…

Independent living is a goal for everyone, but often persons with intellectual disabilities (ID) have major challenges in this respect.

Due to the heterogeneity of ASD symptoms, communication deficits, and impairments in intellectual functioning, assessing symptoms of psychopathology is complicated. The "Autism Spectrum Disorders-Comorbidity for…

A substantial research literature is beginning to develop regarding social skills excesses and deficits for children with autism spectrum disorders. These developments are likely to continue given the increasing recognition that these behaviors are among the most critical core symptoms of these disorders. A review is provided of developments in…
