Objective:
Disruptive behavior disorder (DBD) adversely impacts children and adolescents. However, a comprehensive and cost-effective scale to assess DBD is lacking in Korea. Therefore, this study translated the Disruptive Behavior Disorders Rating Scale (DBDRS) into Korean and analyzed its psychometric properties.
Methods:
Parents and primary caregivers of non-clinical (n=429) and clinical (n=28) children and adolescents aged 6-15 years were included in the analysis. Confirmatory factor analysis was conducted; further, concurrent validity and internal consistency were investigated using correlation analysis and Cronbach's alpha, respectively. Furthermore, discriminative capacity was estimated using receiver operating characteristic curve analysis.
Results:
The four-factor model of K-DBDRS showed good model fit indices and factor loadings, which supported the construct validity of the scale. Strong correlations between K-DBDRS and related measurements were observed, and a robust level of Cronbach's alpha was confirmed (0.891-0.933). The discriminative capacity of the scale was good, based on the area under the curve values (0.933-0.953).
Conclusion:
This study indicated that the K-DBDRS is an appropriate screening tool for Korean children and adolescents. Thus, this scale can be applied in clinical and community settings to identify children and adolescents with disruptive behavior disorders.
