Exploring the Incredible 5-Point Scale: Impact on Target Behaviors in Preschool
In the following experimental study, a multiple-probe, single subject design (SSD) was used to evaluate the effectiveness of the Incredible 5-Point Scale (Buron & Curtis, 2012) as an intervention tool for a preschool aged child with developmental delays (DD). The scale, originally designed for individuals with Autism Spectrum Disorder (ASD) but found through noted experiences to have positive effects for individuals with other disabilities as well, is a teaching tool that aids teachers, therapists, and families in encouraging positive social and behavioral development in individuals (Buron & Curtis, 2012). While not an identified evidence-based practice (EBP) itself, the Incredible 5-Point Scale does utilize many EBP in its implementation and development. Therefore, the purpose of this study was to determine the effectiveness of the scale in modifying the target behavior of a four-year-old male with DD by using visual analysis, percentage of nonoverlapping data points (PND), and percentage of data exceeding the median (PEM) to indicate whether or not the scale was effective. After the implementation of the intervention, the participant’s target behavior (inappropriate play with peers) decreased between baseline and intervention phases across all three activities. Practice and research implications as well as study limitations are discussed.
