The Reliability of the Japanese Manuals for the Aberrant Behavior Checklist in Daycare Center for Handicapped Children

Abstract

[Purpose] The purpose of the present study was to investigate the reliability of Japanese manuals for the Aberrant Behavior Checklist (ABC-J) in daycare centers for handicapped children. [Subjects] Nine handicapped children with mental retardation, cerebral paralysis, etc were the subjects. [Methods] Four raters (one physical therapist: PT, one occupational therapist: OT, and two nursery teachers) individually used the ABC-J in an inter-rater reliability to determine the reliability of the result between different raters. Intra-rater and inter-rater reliability were examined using the Intraclass Correlation Coefficient (ICC). [Results] Inter-rater reliability ICC (2.1) were 0.582, 0.144, 0, 0.494 and 0.467 for Irritability, Lethargy, Stereotypy, Hyperactivity, and respectively. In intra-rater reliability ICC (1.1), the ICCs of the PT were 0.720, 0.991, 0.996, 0.902, and 0.261 for each item, and those of the OT were 0.578, 0, 0.636, 0.288, and 1. [Conclusion] Some items had inter-rater reliability. In the intra-rater reliability, the score was 0.7 or more, excluding the item of Inappropriate speech for the PT and were 0.57 or more, excluding the items of Lethargy and Hyperactivity for the OT.
