Consultation on the Functional Assessment of Students with Severe Challenging Behavior in a Japanese Special School for Intellectual Disabilities.

Background: It is important to intervene early and treat children and individuals with behavioral disorders. We conducted a functional assessment-based consultation for teachers of several students with severe behavioral disorders and examined the effects of the consultation.

Methods: Eight students with severe behavioral disorders were selected from two special schools for intellectual disabilities in western Japan. An external consultant team conducted a functional assessment-based consultation in cooperation with a team of teachers. Consultations were held once a month, and comprised three to six sessions per student.

Results: As a result of the functional assessment, only 8 out of 10 behaviors with some communication function, and 2 with only sensory enhancements were estimated. The Effects of consultations based on functional assessment were presented. It was found that 6 out of 10 target behaviors had obtained high effects. The total score for each behavioral scale showed a statistically significant improvement.

Conclusion: Although consultations lasted for only six months and occurred from three to six times for each student, scale scores for problem behavior before and after intervention were improved, overall. Each case report suggested that many factors influence the difference in the effects of consultation among individual students. This study is significant in that it provides a model for the consultation system that operates on a short-term basis, and presents a means for small-scale group consultations for students with intellectual disabilities and autism in cooperation with external specialized institutions in special schools in Japan.
