Content validity describes the extent to which a measure represents, and is relevant to, the construct it aims to assess. The International Classification of Functioning, Disability and Health and derived Core/Code Sets (Sets) for autism, attention deficit-hyperactivity disorder, cerebral palsy and early developmental delay and disability are…

The Parent-Child Relationally Informed Early Intervention was developed from the clinical application of attachment theory. The premise is to expand the responsiveness of parents and clinicians working with children who have developmental delays. It was evaluated via four single case studies (children aged 18-months to 6 years) using an AB(A)…

Children with developmental disorders often have poor motor performance. This study aimed to address the association between tactile localization ability, an indicator of body image, and motor function in children with motor deficits. Eighteen children with motor deficits participated, and their upper and lower limbs were assessed. To assess the…

Covert self-injurious behavior (i.e., behavior that occurs in the absence of other people) can be difficult to treat. Traditional treatments typically have involved sophisticated methods of observation and often have employed positive punishment procedures. The current study evaluated the effectiveness of a variable momentary differential…

Self-injurious behavior (SIB) is a devastating condition associated with intellectual and developmental disabilities (IDD). Efforts to understand its development are focused on early childhood when the behavior first emerges. Limited prevalence data on SIB during early childhood are currently available. The purpose of this study was to determine…

Background: Can ratings of temperament be a way of identifying young children with intellectual disabilities (ID) who are at risk for being experienced as difficult? We aimed to explore parents' reports of temperament in their young children with or without ID, as well as positive and negative impact of the child on parents. Method: Mothers and…

A prospective study of the families of young severely disabled children applying to a non-governmental organization for financial support examined the respective contributions of a child's intrinsic impairment and the family's environment to their participation. The study population comprised the families of 600 children of median age 2 years 8…

This study assessed differences in oromotor development between 10 verbal and 10 nonverbal young children (ages 30 to 48 months), all with autism. A variety of oromotor difficulties were found in both groups, similar to those seen in children with cerebral palsy and Down syndrome. (DB)
