The use of behavioral skills training (BST) to educate 3 adolescent boys on the risks of lighters and fire setting was evaluated using in situ assessment in a school setting. Two participants had a history of fire setting. After training, all participants adhered to established rules: (a) avoid a deactivated lighter, (b) leave the training area,…

Two studies were conducted that examined the preference of a student diagnosed with a brain injury. In Study 1, a preference assessment was followed by a three-choice concurrent operants reinforcer assessment. Two choices resulted in access to preferred activities for completing work, and a third choice resulted in access to nothing (i.e., no…

Repetitive behaviors such as excessive straightening are commonly observed among individuals with autism. Attempts to prevent these behaviors may increase the likelihood of other problem behaviors. The present study was designed to assess and treat the excessive straightening and associated destructive behaviors of a 16-year-old boy who had been…

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e.,…

Functional analysis conducted during a 90-minute evaluation session identified maintaining variables for aggressive behavior and an alternative replacement response in 3 individuals with severe handicaps. During a subsequent contingency reversal phase, aggressive behavior was substantially reduced and alternative behavior increased. Results…

Four experiments involving 18 individuals (ages 14-55) with profound multiple handicaps found that 12 stimuli used in a preference assessment represented a comprehensive stimulus set for identifying preferences, though the utility of the set could sometimes be enhanced by caregiver opinion. Results also indicated that preferences identified were…

A behavioral assessment procedure was evaluated with five children with severe/profound mental retardation who exhibited feeding problems of limited intake. Subjects were fed various types of foods. Results indicated each subject fit into one of four categories: (1) total food refusal, (2) food type selectivity, (3) food texture selectivity, or…

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…

Tangible preference assessments were compared with verbal preference assessments for six individuals (ages 15-20) with mental retardation, behavior disorders, or both. The two assessments yielded similar high-preference items for 4 of the 6 participants. The verbal assessment was typically completed in less time than the tangible assessment.…

A procedure enabling 19 adolescents/adults with profound mental retardation to express food and drink preferences was evaluated. Results indicated that active choice making occurred, and caregiver opinion was not predictive of participant preferences. Choices made using the procedure were similar to choices made when less structured opportunities…

A study involving three individuals (ages 13-20) with developmental disabilities and problem behaviors examined the influential role that unanticipated idiosyncratic stimulus variables play in affecting the outcome of a functional analysis. Guidelines are discussed concerning when to suspect that idiosyncratic stimuli might be acting to influence…

A socially valid behavior-change intervention is broadly defined to be directed to a problem of verifiable importance, be accepted and used appropriately by target groups, and reduce substantially the probability of the problem's occurrence in target populations. The definition is applied to a family-based program to prevent human immunodeficiency…
