In recent years there has been a shift to recognise the needs of siblings and a growth in sibling support largely for under 16s. However, siblings will often require support into adulthood as they undertake additional responsibilities from parents in the care or advocacy of their brother or sister. Therefore this project aimed to investigate what…

Exploratory factor analysis (EFA) is a widely used but poorly understood statistical procedure. This paper described EFA and its methodological variations. Then, key methodological variations were used to evaluate EFA usage over a 10-year period in five leading developmental disabilities journals. Sixty-six studies were located and evaluated on…

Safety skills are an important but often neglected area of training for persons with developmental disabilities (DD). The present study reviewed the literature on teaching safety skills to persons with DD. Safety skills involve a variety of behaviors such as knowing how to cross the street or what to do in case of a house fire. A number of studies…

The purpose of the present investigation was to evaluate the relative effectiveness of three item presentation methods during noncontingent reinforcement (NCR). Four individuals with developmental disabilities and problem behavior maintained by automatic reinforcement were recruited for the study. Single-item stimulus preference assessments were…

Extension educators and volunteers provide programs to people of all ages and abilities. This includes individuals with developmental disabilities. Individuals with autism and other developmental disabilities often have difficulty communicating verbally but have strong visual learning skills. This article describes the importance of using visual…

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…

Developmental coordination disorder (DCD) has been classified as a specific learning disability, nonetheless the underlying cognitive mechanisms are still a matter of discussion. After a summary of the main hypotheses on the principal neuromotor causes of DCD, this study applies a causal model framework to describe the possible coexistence of more…

Participation is recognized as a key to one's health and well-being and is considered to be a vital part of the development of children and youth. The purpose of this study was to examine the participation patterns of children with and without Developmental Coordination Disorder (DCD) in their out-of-school-time (OST) activities, and to see…

The characteristics of early developmental regression (EDR) were investigated in individuals with ASD from affected relative pairs recruited to the International Molecular Genetic Study of Autism Consortium (IMGSAC). Four hundred and fifty-eight individuals with ASD were recruited from 226 IMGSAC families. Regression before age 36 months occurred…

The Movement Assessment Battery for Children-2 (M-ABC-2) is one of the most commonly used tests for the diagnosis of specific developmental disorders of motor function (F82). The M-ABC-2 comprises eight subtests per age band (AB) that are assigned to three dimensions: manual dexterity, aiming and catching, and balance. However, while previous…

The defining feature of Developmental Coordination Disorder (DCD) is the marked impairment in the development of motor coordination (DSM-IV-TR, American Psychiatric Association, 2000). In the current study, we focused on one core aspect of motor coordination: learning to correctly sequence movements. We investigated the procedural, visuo-motor…

Choice making represents the central element of self-determination, and efforts are being made across all service programs to promote choice making for consumers with intellectual and developmental disabilities. Although choice making appears to be a relatively simple response for a consumer to perform (selecting one stimulus over another), it is…

This cumulative author index was developed as a service for the readership of Education and Training in Autism and Developmental Disabilities. It was prepared as a resource for scholars wishing to access the 391 articles published in volumes 36-45 of this journal. It also serves as a timely supplement to the 25-year (1966-1990) cumulative author…

Data from 368 families of children with autism and other developmental disabilities in the People's Republic of China were gathered to understand the stresses that families experience and the coping strategies they employ. Chinese families of children with developmental disabilities perceived high levels of stress related to pessimism, child…

The present study tested whether parents caring for children with developmental disabilities would have higher blood pressure compared to parents of typically developing children (controls). It also examined the psychosocial factors underlying this observation. Thirty-five parents of children with developmental disability and thirty controls…
