Abstract

Given the importance of competencies in functional behavior assessment (FBA) and behavioral interventions among teachers for managing problem behaviors among children with autism spectrum disorder (ASD) and other developmental disabilities, a previously reported ability in behavior assessment and interventions for teachers (ABAIT) needed improvements in the multiple-choices by adding a 'don't know' option. This study reports on the psychometric properties of this revised scale (ABAIT-R) among 102 special educators assessed using Rasch models. It was found that the model had good fit and a wide spread of difficulties (3.63 to - 2.60). ABAIT-R had good targeting (over 85%) and high reliability (0.79). The assumptions of the model were met recommending sufficiency for the use of summated score from ABAIT-R among teachers.
