Identification of the Function of Problem Behavior Using Functional Assessment: Based on Types of Observer and Problem Behavior

Although identification of the function of problem behavior can be influenced by observers or types of problem behaviors, there is lack of studies analyzing these factors. The purpose of this study, which is focused on people with developmental disabilities, was to identify the functions of problem behaviors reported by three different groups of caregivers(teachers, staff/therapists, and parents), and types of problem behaviors(self-injurious, attack, destroy, stereotype, tantrum, others). Total of 473 participants answered basic information record and Functional Assessment for the Challenging/Problem Behaviors (FAPB). Results show that there was no significant difference in function of problem behavior across observers, but the main effect of the problem behavior type was observed. As a result of post-analysis of observer variables, demand was reported the least in the parent group. Attack and self-injurious behavior were significantly related to demand and avoidance, which was consistent with previous studies. interaction between two independent variables was not significant. Utilization of the result in the clinical field and further research was suggested.
