This study assessed teachers' abilities to conduct functional assessments and functional interventions in the classroom setting with students who had developmental disabilities and behavior problems. The results showed that information on antecedents and consequences was consistent when derived from a structured behavioral questionnaire completed by the teacher or when the questionnaire was administered in an interview format by a behavior analyst. Although raters agreed on the hypothesized function of problem behaviors of three students with disabilities based on information from the questionnaire and interview, behavioral functions hypothesized by separate raters for the questionnaire and interview varied for one student, indicating problems with interrrater reliability. Results also revealed that teachers without specialized training in applied behavior analysis are able to carry out direct observations of behavior problems, antecedents, and consequences, and produce information on antecedents and consequences comparable to that of graduate students with 2 years of training in applied behavior analysis. Lastly, implementation of functional and nonfunctional interventions (likely to be implemented in typical classrooms) provided support for the hypothesized functions from both indirect and direct methods of assessment.

Conventional structural imaging is often normal after mild traumatic brain injury (mTBI). There is a need for structural neuroimaging biomarkers that facilitate detection of milder injuries, allow recovery trajectory monitoring, and identify those at risk for poor functional outcome and disability. We present a novel approach to quantifying volumes of candidate brain regions at risk for injury. Compared to controls, patients with mTBI had significantly smaller volumes in several regions including the caudate, putamen, and thalamus when assessed 2 months after injury. These differences persisted but were reduced in magnitude 1 year after injury, suggesting the possibility of normalization over time in the affected regions. More pronounced differences, however, were found in the amygdala and hippocampus, suggesting the possibility of regionally specific responses to injury.

This study utilized descriptive assessment methods to develop hypotheses regarding the function of mealtime behavior problems for three typically developing children. Functional treatment was evaluated in the natural setting with caregivers as change agents. Overall, results of the descriptive assessment suggested that each child's problem behavior was maintained by escape and, to a lesser extent, attention. In addition, this study suggested that direct observation was more reliable than a behavioral interview or questionnaire in acquiring the information necessary to develop hypotheses on factors maintaining a child's mealtime behavior problems. Finally, a functional treatment package consisting of extinction, stimulus fading, and reinforcement of appropriate eating behaviors implemented by the caregivers was effective in decreasing the mealtime behavior problems for two of the children who continued in the study, thus providing support for the hypotheses developed from the assessment.

We analyzed and treated the finger sucking of 2 developmentally typical children aged 7 and 10 years. The functional analysis revealed that the finger sucking of both children was exhibited primarily during alone conditions, suggesting that the behavior was maintained by automatic reinforcement. An extended analysis provided support for this hypothesis and demonstrated that attenuation of stimulation produced by the finger sucking resulted in behavior reductions for both children. Treatment consisted of having each child wear a glove on the relevant hand during periods when he or she was alone. Use of the glove produced zero levels of finger sucking for 1 participant, whereas only moderate reductions were obtained for the other. Subsequently, an awareness enhancement device was used that produced an immediate reduction in finger sucking.
