Abstract

Background: The Eyberg Child Behavior Inventory (ECBI) is one of the standardized parent rating scales used to identify disruptive behavior problems in children in Western countries. This study aimed to determine norms for the Japanese version of the ECBI, including clinical cutoff scores among the general population in Japan.

Methods: This study established norms for the Japanese version of the ECBI using a sample of 1,992 parents of children aged 2-7, living in Japan. The research evaluates the validity and the reliability of the ECBI scores for the Intensity Scale and the Problem Scale. After validation, a clinical cutoff value of the ECBI scores was calculated, setting the cutoff to above the +1 standard deviation (SD) level based on the population distribution.

Results: The means of the Intensity and Problem Scale scores were 100.07 and 6.57, respectively. Cronbach's α for both the Intensity and the Problem scores was 0.91. At this point, we propose cutoff scores of 125 for the Intensity Scale and 14 for the Problem Scale.

Conclusions: Our results suggest that the Japanese version of the ECBI is highly reliable and may be useful as a tool for assessing behavior problems in children.
