Abstract


OBJECTIVES
Symptoms of attention-deficit hyperactivity disorder (ADHD) during childhood may persist into adulthood. This study included the development and validation process of the Korean Adult ADHD Rating Scale (K-AARS), which was developed for screening and monitoring treatment of adults with ADHD.
METHODS
Preliminary questionnaires of the K-AARS were based on the reviews of previous adult ADHD scales and clinical experiences of the board certified child and adolescent psychiatrists in Korea. For this study, 136 adults (18-50 years old) with inattention, hyperactivity and/or impulsivity symptoms were enrolled as ADHD subjects, and compared with 406 control subjects (18-50 years old) without ADHD symptoms. Construct validity was examined using explorative factor analysis and Cronbach's alpha to obtain internal reliability coefficients. Concurrent validity was evaluated by comparison with the Conners' Adult ADHD Rating Scale (CAARS).
RESULTS
An explorative factor analysis showed that the K-AARS had 8 factors (inattention, hyperactivity, impulsivity, antisocial personality disorder/conduct disorder/oppositional defiant disorder, impairment, driving, emotional dysregulation, disorganization). K-AARS was highly reliable in terms of internal consistency (Cronbach's alpha 0.77-0.95) and correlation between factors (0.57-0.86). Concurrent validity with the CAARS and discriminant validity were statistically significant.
CONCLUSION
The K-AARS is a valid and reliable measure for assessment of Korean adults with ADHD.
