Abstract
OBJECTIVES
This study was conducted to develop the Korean version of the IOWA Conners rating scale (K-IOWA), and to examine its reliability and validity.
METHODS
The subjects were 41 normal children and 40 ADHD children between the ages of 5 and 12. All of the teachers administered the K-IOWA and the abbreviated Conners' rating scale to calculate the internal consistency coefficient of the K-IOWA and to examine its validity.
RESULTS
The reliability coefficient of the K-IOWA (Cronbach's alpha) was .913. The range of correlation coefficients between K-IOWA scores and the Abbreviated Conners Rating Scale scores were from .81 to .93. The mean score of the ADHD group on the K-IOWA was significantly higher than that of the normal group. The result of factor analysis showed that the K-IOWA was composed of 2 factors (Inattention/Overactive and Oppositional/Defiant).
CONCLUSION
These results suggest that the K-IOWA rating scale is a very reliable and valid test and it would be useful in diagnostic evaluation and the treatment effect for ADHD children.
