The Effects of Positive Behavior Support(PBS) on the Inattentive & Disruptive Behaviors of an At-risk Child

The purpose of this study is to investigate the effect of positive behavioral support on the behaviour of children with at risk for disability. One at risk child with disability belonging to the public kindergarten was selected for the study & a functional assessment was conducted using the method of interview, direct observation, hypothesis setting, & verification to understand the function of the child's distracting behaviors and interference behavior. Based on the results, multiple elements including background & prior event mediation, replacement technical professor intervention, & subsequent outcome arbitration were conducted. In this study, multiple baseline across conditions design was used between situations, & measurements were taken using partial interval recording for 10 minutes each session. Basic lines & intervention were conducted in three situations, including story-sharing activity, free play activity, & lunch-time, focusing on kindergarten classrooms where activities of the children were conducted. In order to investigate the maintenance effect of the behavioral change after one week after the intervention, maintenance observation was performed in the same experimental environment as the baseline, and treatment fidelity and social validity were measured. The results of this study were derived as follows. First, the distracting behaviors of target child were effectively reduced through positive behavior support based on functional evaluation. Second, positive behavioral support based on functional assessment effectively reduced the interfering behavior of the target child. Third, even after ending positive behavioral support interventions, the effects of changes in the attention-based behaviour & interference behavior of the target child were maintained. As above, positive behavioral support has had a positive effect on the reduction of distracting behavior & disruptive behavior for at risk child. This result suggests that positive behavior support is effective in reducing the problem behaviors of young children with disabilities. The study was meaningful in that positive behavior support reduced the incidence of problem behavior in target child proved positive behavior support to be a useful strategy for managing behaviour for young children with disabilities in early childhood special education setting.
