OBJECTIVE To evaluate the impact of a family-based group intervention for young siblings of children with chronic illness and developmental disability (CI/DD). METHODS Forty-three healthy siblings (ages 4-7 years) of children with CI/DD and their parents participated in an intervention designed to address sibling challenges that cut across types of diagnostic conditions. The intervention cons...

The current study examined whether stimuli of different preference levels would be associated with different amounts of work maintained by the stimuli, as determined through progressive-ratio schedule break points. Using a paired-choice preference assessment, stimuli were classified as high, moderate, or low preference for 4 individuals with developmental disabilities. The stimuli were then tes...

BACKGROUND The Bayley Scales of Infant and Toddler Development (III) is a tool developed in a Western setting. AIM To evaluate the development of a group of inner city children in South Africa with no neonatal risk factors using the Bayley Scales of Infant and Toddler Development (III), to determine an appropriate cut-off to define developmental delay, and to establish variation in scores don...

Results of longitudinal studies suggest that the stability of preferences varies across individuals, although it is unclear what variables account for these differences. We extended this work by conducting periodic assessments of preference for leisure activities over 3 to 6 months with 10 adults with developmental disabilities. Although previous research has collectively shown that preferences...

This paper describes the use of a combination of intra-oral sensory stimulation and electropalatography (EPG) in the treatment of a case with severe developmental verbal dyspraxia. A multiple-baseline design was used. The treatment duration was 11 months and started when the subject was 5 years old. The efficacy of the treatment was assessed by calculations of percentage of correctly articulate...

Evaluations of competency to stand trial (CST) in defendants with mental retardation or borderline intellectual functioning can be difficult when deficits are masked by the type of adaptations seen in many with developmental disabilities. Accordingly, many evaluators have used validated test instruments, such as the CAST*MR (Competence Assessment to Stand Trial for Defendants with Mental Retard...

This article discusses screening of language development in a pediatric office setting. It describes the relationship between language delay and various developmental disorders. It provides recent recommendations regarding the efficacy of formal language screening instruments, and suggests developmental guidelines for clinical observations. Referrals for specialty evaluations and services for e...

Background An evaluation of the developmental competence of vitrified mouse germinal vesicle (GV) oocytes with various equilibration and vitrification times; in the presence or absence of cumulus cells and by comparison between the cryotop method and straws was performed. MaterialsAndMethods Mouse GV oocytes were considered in cumulus-denuded oocytes (CDOs) and cumulus-oocyte complexes (COCs) g...

Past research has demonstrated that pictorial preference assessments can predict subsequent reinforcement effects for individuals with developmental disabilities only when access to the selected stimulus is provided contingent on a pictorial selection. The purpose of the present investigation was to assess more comprehensively the feasibility of the pictorial format with children with developme...

According to the literature, 12 to 16 percent of children in the United States have at least one developmental delay, yet as many as one-half of affected children will not be identified by the time they enter kindergarten. If developmental delays are detected too late, opportunities for early intervention may be lost. Empirical literature on clinical recommendations for developmental delay scre...
