Abstract
This study was designed to determine whether behavioral treatments would be preferred over no treatment (baseline) conditions. Functional analyses and descriptive observations were conducted to determine the variables that maintained each participant's problem behavior. Next, treatments were implemented based on assessment results. Finally, participants were provided a choice between baseline and treatment conditions to determine whether they preferred to participate in treatment. Baseline conditions were in place on one side of a room and treatment conditions were in place on the other side of the room. Assessment results suggested that problem behavior was automatically reinforced for one participant and multiply controlled for another participant. The treatment results showed that differential reinforcement and extinction (extinction was not implemented for automatically reinforced behavior) were effective in reducing problem behavior for each participant. Results of the choice between baseline and treatment phase showed that both participants chose treatment over baseline conditions. Copyright ยฉ 2007 John Wiley & Sons, Ltd.
