Combining descriptive and experimental analyses of young children with behavior problems in preschool settings.

This investigation shows the merits of preceding experimental analyses with descriptive analyses of functional variables with preschool children who engage in problematic behavior. A two-phase descriptive analysis was conducted in daycare settings with three children. In Phase 1, the authors assessed the relation between child behavior and structural events. During Phase 2, the same behavior was replotted by functional variables. The results showed that when the descriptive data were plotted via functional variables, specific hypotheses could be generated regarding the variables controlling appropriate behavior. This procedure permitted the subsequent use of very brief experimental analyses to further identify functional relations. The use of descriptive analyses of functional rather than structural variables may be an important component in the assessment of problem behavior in community settings.
