Objectives: The purpose of this study was to examine the reliability and validity of the Korean version of the Behavior Problems Inventory (BPI-01) among children and adolescents aged between 3 and 18.
Methods: The control group consisting of one hundred children and adolescents was recruited from schools and the patient group consisting of forty one children and adolescents with autism spectrum disorder were recruited from a hospital. We compared the measurements of both groups. To assess the concurrent validity of the BPI-01, we compared the problem behavior index of the Korean Scale of Independent Behavior-Revised (K-SIB-R) and, to assess the discriminant validity, we compared the Korean version of the Child Behavior Checklist (K-CBCL). The Cronbach’s alpha of the BPI-01 was measured to assess its reliability. Correlation analyses between the BPI-01 and the other scale were carried out to examine the former’s concurrent and discriminant validity.
Results: The patient group showed a significantly higher score for all three subscales of the BPI than the control group. The Cronbach’s alpha was 0.92 for the total severity score of the BPI and ranged between 0.67–0.89 for each subscale in the patient group. All subscales of the BPI-01’s, i.e., self injurious behavior, stereotyped behavior and aggressive/destructive behavior, were significantly correlated with the corresponding subscales of the K-SIB-R. The BPI-01 generally did not demonstrate any significant correlation with emotional items such as anxiety/depression in the K-CBCL. Especially, the BPI-01’s stereotyped behavior subscale showed little correlation with externalizing behaviors such as social problems and aggressive behaviors.
Conclusion: This study found that the Korean version of BPI-01 is a reliable and valid behavior rating instrument for problem behavior in developmental disabilities among children and adolescents.
