This study assessed the validity of idiosyncratic choice-making behaviors of three children with multiple disabilities. Children were given either their "choice" of food or drink or were given the opposite. Direct observations of children's acceptance or refusal revealed the children consistently indicated choices during both conditions.…

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

A review of research on state behavior among students with profound disabilities is presented, and a model depicting interactions of state with endogenous and exogenous variables is offered. Applications of the model are illustrated through four case studies displaying different state patterns. Measurable attributes of state having implications…

Individuals with developmental disability (n=400) were assessed with the "Dyskinesia Identification System: Condensed User Scale" (DISCUS), a 15-item tardive dyskinesia rating scale shortened from the "Dyskinesia Identification System-Coldwater." Based on interrater reliability, 2-week stability, and other analyses, DISCUS is…

This study evaluated a method for assessing the behavioral function of severe self-injury in four adults with severe/profound mental retardation. Initial assessment included analyzing within-session trends and fluctuations in rates of self-injury by plotting the frequency within each minute of the session. (DB)

Examines relations between Matthews Youth Test for Health ratings on hyperactive boys and diverse measures obtained from five sources: direct behavior observations; staff evaluations, nonparticipant observer ratings, peer nominations, and self-reports. (HOD)

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,…

Youth violence is a serious global public health problem. Despite a decline in homicide rates across the United States during the 1990s, homicide rates are again rising and continue to claim the lives of many young people. The human and economic toll of violence on young people, their families, and society is high. Homicide is the second leading…

The representativeness of behavioral observation samples with durations of less than the whole time of interest was investigated with five profoundly mentally retarded physically handicapped adults in an institutional setting. It was found that the session representativeness was a function of the relative duration of the behavioral categories and…

Functional analysis of the aggressive behavior of 2 boys (ages 10 and 12) with autism involved 20 brief functional assessment trials in the classroom under 3 conditions. Results showed a clear pattern in each child's aggressive behavior and suggested logical intervention strategies. The discrete-trial approach presented a practical, ecologically…

This study examined whether teacher-implemented classroom measurement procedures of short duration are as reliable as methods used in research studies to determine behavior state (e.g., awake active, awake inactive, asleep, drowsed) of six students with profound mental disabilities. Results indicated that more frequent but briefer measurements…

This paper summarizes brief functional assessments of 79 cases of people with developmental disabilities and self-injurious, aggressive, stereotypic, or other aberrant behavior. Outcomes were evaluated across three variables: (1) referring topography, (2) control over behavior, and (3) the identified maintaining conditions for aberrant behavior.…

Education is one important role of zoos, but there is relatively little research on the extent to which zoos are serving this role. Traditional methods for collecting and analyzing such information have significant disadvantages in zoo settings and should be supplemented (not replaced) by nonreactive measures. To test this concept, teams of…

Evaluation of 26 children (ages 24-55 months) with pervasive developmental disorder (PDD) while interacting with either the mother, a familiar female teacher, and an unfamiliar male doctor. PDD subjects were most severely impaired during the mother episode. During the teacher episode, PDD subjects were twice as variable in interpersonal response…

Health risk behaviors (substance use, violence, suicide, and car safety) of 194 African American urban adolescents with mild mental retardation were measured using either a confidential individual interview or an anonymous group survey. The survey methodology resulted in disclosure of more risk behaviors than the interview methodology. Elevated…
