Objective: The purpose of this study is to assess the psychometric properties and to investigate factor structure of the Korean version of the Young ADHD Questionnaire-Self-Report (K-YAQ-S) and the Young ADHD Questionnaire-Informant-Report (K-YAQ-I).
Methods: 269 normal college students completed the K-YAQ-S and the Lee Ji-Yeon’s adult ADHD scale (1996). 213 informants of the subjects completed the K-YAQ-I.
Results: The K-YAQ-S and the K-YAQ-I had good internal consistency (Cronbach’s =.957, .965). An ADHD symptomatology and emotional problem subscales of the K-YAQ-S showed strong correlation with the Lee Ji-Yeon’s adult ADHD scale. The delinquency and social functioning subscales of the K-YAQ-S and all subscales of the K-YAQ-I correlated significantly but were relatively lower. An exploratory factor analysis showed that the K-YAQ-S revealed 4 factors (ADHD symptomatology, emotional problems, delinquency, social functioning) and the K-YAQ-I being composed of 3 factors (ADHD symptomatology/ aggressive behavior, emotional problem/social functioning, illegal act).
Conclusion: These results suggest that the K-YAQ-S and the K-YAQ-I rating scale is a reliable and a valid test. These scales would be useful in diagnostic evaluation and in measuring the treatment effect for ADHD adult.
