Functional Analysis and Effects of Precursor Behavior Intervention of a Student With Profound Autism: A Preliminary Study in Taiwan

Abstract:

Literature on severe challenging behavior and precursor assessment is unexplored in Taiwan. The authors conducted functional analysis and intervention on precursor behavior in order to improve a series of challenging behaviors (i.e., constant tapping objects, biting or hitting a person, hitting floor with head, and vigorously hopping on chair) of a vocational high school student with profound autism. We selected the tapping objects as the precursor behavior. A single subject multi-element research design with functional analysis and constant reversal design to establish internal validity of the effectiveness of the intervention was used. We found precursor behavior itself served as a function of automatic reinforcement. Sponge and ear plug were selected to investigate the effects. A functional relationship was found between using ear plugs as an alternative sensory input and decreasing precursor behavior. Furthermore, based on anecdotal observation, all other severe challenging behaviors were then eliminated. This study established initial evidence of effectiveness in precursor behavior assessment in Taiwan. Future practitioners as well as researchers can ensure implementation of more proactive education strategies, such as expanding students’ interest and teaching social-communication skills.

 
Target Audience:

Attendees should be familiar with Iwata's functional analysis. 

Learning Objectives: At the conclusion of the presentation, participants will be able to: (1) provide an overview on precursor behavior assessment literature; (2) discuss the first preliminary study on precursor in Taiwan and the challenges encountered.
