Paired and group presentation methods of preference testing were compared with eight adults with severe-profound developmental disabilities. Each presentation method was also compared with staff rankings of learners' preferences. Similar preferences were identified with both methods. Staff preference rankings were not highly correlated with those…

Available information is reviewed on defining features and diagnostic issues related to autism and related developmental disorders. Controversies over both the boundaries and the heterogeneity within the autism syndrome are evaluated. Diagnostic rating instruments for expediting systematic sample selection are critiqued.

This analysis of the descriptive information on subjects provided by 266 research reports on autism and developmental disabilities found a continuing trend toward more complete descriptive information; increased use of control or comparison groups; less research in biological, physiological, and neurological areas; and more research in the social,…

This study assessed the criterion validity of the photographic adaptive communication device (ACD) used in Oklahoma to interview individuals with developmental disabilities receiving services. The back-translation process identified photographs that were frequently incorrectly identified resulting in revision of the ACD for greater validity.…

Analog baselines are an experimental methodology for identifying the functions of maladaptive behavior of individuals with developmental disabilities in naturally occurring environments. This article identifies potential limitations of this methodology, including: fidelity of baseline design conditions, a narrow analysis of behavior, and limited…

Aimed to determine to what degree newborns' auditory brainstem evoked responses (ABRs) predict delayed or impaired development during the first year. When 93 infants' ABRs were evaluated at three, six, and nine months, newborn ABR was moderately sensitive for detecting hearing impairment and more sensitive than other indicators in detecting…

This article discusses clinical application of functional analysis in developmental disabilities, reviewing issues related to treatment logic and development. The article then approaches functional analysis as a research method, reviewing three areas of research: analysis of diverse response topographies, analysis of basic behavioral processes,…

Data are summarized from 152 single-subject analyses of the reinforcing functions of self-injurious behavior (SIB) in individuals with developmental disabilities. Overall results indicated that functional analysis methodologies are extremely effective in identifying the environmental determinants of SIB on an individual basis and, subsequently, in…

This meta-analysis of the developmental disabilities literature on remediation of problem behaviors evaluated relations between standards of practice, intervention and participant characteristics, and treatment validity. Results largely failed to support widespread assumptions of clinical practice such as the superiority of more intrusive…

A review of studies that used the Questionnaire on Resources and Stress with families rearing children with developmental disabilities identified three primary difficulties: (1) definitional problems: (2) multiple measures of the same construct that do not converge: and (3) failure to replicate. Solution strategies include separating demands,…

This study reviewed 113 research articles involving 299 subjects and a corresponding sample of 299 adaptive skill programs implemented in state-funded residential facilities for adults with developmental disabilities. Statistical analysis revealed significant differences between researchers and clinicians in adaptive and maladaptive behavior…

This compilation presents five papers on issues and research in special education. "Qualitative Research in Special Education: An Evaluative Review" (Charles A. Peck and Gail C. Furman) explicates some of the epistemological assumptions underlying qualitative research methods, reviews examples of qualitative research, evaluates the contributions…
