Abstract
[Purpose] In this study, examines the intra-rater reliability of the Japanese version of the Aberrant Behavior Checklist (ABC-J) was examined with physical therapists and occupational therapists serving as the raters. [Subjects] The subjects were 12 mentally retarded children. Physical therapists rated all 12 subjects, whereas occupational therapists rated 11 of the 12 subjects. Fifteen physical and occupational therapists subjects, excluding one subject. Raters were 15 PT and OT working at T Hospital who knew the subject children well served as the raters. [Method] Each rater individually assessed the subject children using the ABC-J. One month after the initial assessment, the same rater assessed the same children again. The first and second ABC-J scores were statistically analyzed using the Intraclass Correlation Coefficient (ICC). [Results] The ICCs (1.2) for the ABC-J scores ranged from 0.745 to 0.975, except for the inappropriate speech scores. [Conclusion] The ABC-J allows anyone to be a rater as long as he/she knows the subject well. The results showed that the assessments by the physical and occupational therapists were relatively reliable.
