| The purposes of this study were to analyze the functions of problem behaviors exhibited by study with autism and to identify the functions maintaining problem behaviors. A total of 818 behavior samplings from 53students with autism were observed for analyzing the function.
The main findings were as follows:
1.Inthe eight categories of problem behaviors, the main functions of problem behaviors maintained by antecedent stimuli were similar. Attention seeking, automatic reinforcement, tangible reinforcement and demand avoidance were the four main functions. Noncompliance and self-injuring functioned less frequently to seek attention. Ritualistic behavior, odd behavior and self-injuring also served as functions of automatic reinforcement and anxiety avoidance.
2.In the eight categories of problem behaviors, the main functions of problem behaviors maintained by consequence stimuli were similar. Except the noncompliance which was maintained by doing the things he wanted and seeking rest, the seven others categories of problem behaviors served as functions of attention seeking, automatic reinforcement, anxiety avoidance, and demand avoidance. The function of problem behaviors showed by students with autism was wide variety.
3.The inter-observer (include videotaped observation and naturalistic observation) reliability of Behavior assessment checklist which developed by researcher were .88 to .92.
