Functional analysis procedures refer to the assessment of behavior using systematic manipulation of environmental events in an attempt to identity the antecedents and consequence that evoke and maintain problem behavior. Functional analysis procedures were conducted in a clinical setting using an analog approximation of the natural environment. In the current study we first conducted a functional analysis to determine whether the type of attention (high-volume/enthusiastic versus low-volume attention) resulted in behavior change. During the functional analysis sessions three different treatments were implemented based upon the assessment results from problem behavior: Negative Punishment Base Treatment (Treatment A), Positive Reinforcement Base Treatment (Treatment B) and a combination of Treatment A and B (Treatment C).Treatment A involved a free play session where problem behavior (aggression, destruction, elopement) resulted in loss of attention, but appropriate behavior resulted in continued attention. Treatment B involved the contingency where-by appropriate behavior would result in access to attention as a reward or reinforcer. The data suggested that problem behavior occurred at a relatively high rate (9.4) during Treatment A, than increased upon going to Treatment B with a rate of 18.2. This pattern treatment remained consistent and led to Treatment C. Treatment C required to first complete a work task (folding towels, or work sheet) with no attention, than once the task was completed the patient received attention for three minutes. The overall linings indicated that Treatment C resulted in a decrease of problem behavior in the clinical setting when problem behavior was previously evoked a regular basis.
