Evaluating the Effects of Function-Based Interventions with D/HH Students

Abstract

This study examined the effectiveness of function-based interventions applied within a school for the deaf. The participants were elementary-aged males diagnosed as deaf or hard of hearing (D/HH) who exhibited chronic off-task behaviors throughout the school day. This study was conducted across two phases: (a) a descriptive functional behavior assessment (FBA) was conducted for each participant and (b) individualized function-based interventions were developed based on the results of the FBAs followed by the implementation of the interventions in each classroom using a single-subject, ABAB reversal design. The function-based interventions significantly improved each participant's on-task behavior in his classroom environment. Furthermore, social validity ratings by each teacher revealed that the interventions were effective, easy to implement, and appropriate for each participant. Implications for application of the procedures used in this study with the D/HH population, limitations, and directions for future research are discussed.
