We examined the psychometric properties of the behavior flexibility rating scale-revised (BFRS-R), a new scale intended for assessing behavioral flexibility in individuals with developmental disabilities. Seventy-six direct care staff members and 56 parents completed the BFRS-R for 70 children with developmental disabilities. Factor analysis revealed three factors (i.e., Flexibility towards objects, Flexibility towards the environment, and Flexibility towards persons) and results of several analyses indicated an excellent internal consistency and good intra-rater and inter-rater reliability of the total scale. These data suggest that the BFRS-R may provide a reliable rating of behavioral flexibility when used by direct-care staff and parents of children with developmental disabilities.
