Abstract

OBJECTIVES
This study was conducted in order to determine the validity and reliability of the Korean Version of the Conners Adult ADHD Rating Scales-42 items & 26 items (K-CAARS-42 & K-CAARS-26) in nonclinical adult subjects.
METHODS
The K-CAARS-42 & K-CAARS-26 was tested in non-clinical (n=270) native Korean-speakers. Internal consistency reliability was calculated using Cronbach's alpha and test-retest reliability was measured using Pearson correlations. To see validity, we performed the confirmatory factor analysis for determination of whether the four-factor model fit the data.
RESULTS
The results showed that the subscales had acceptable internal consistency reliability and high test-retest reliability ; and the second-order scores showed significant correlation with the Korean version of the Barratt Impulsiveness Scale-11-Revised and Prospective and Retrospective Memory Questionnaire. The Confirmatory factor analysis revealed a four-factor structure of both K-CAARS-42 and K-CAARS-26.
CONCLUSION
The K-CAARS-42 & K-CAARS-26 is reliable and has possible utility for symptom assessment of attention deficit and hyperactivity disorder in nonclinical adult subjects. Further research is needed in order to determine the cutoff score for administration of the K-CAARS-42 & K-CAARS-26 to clinical adult subjects.
