The authors applied ADDES-HV parent evaluation scale for the purpose of screeing test to 538 2nd grade elementary school students from March 1994 to May. The results were as follows: There was no differences in scores of ADHD between schools. In comparing the male and female between three school students, male students showed signifieant high scores (p<0.05) than female students in the score of ADDES-HV subscale and total. There was no significant differences in ADDES-HV scale between male students and female students in both ADHD patients and normal controls. In reliability test for test and retest, the reliability coefficient was higher satisfatorily and that of inattention was 0.80, inpulsivity was 0.69, hyperactivity was 0.63 and the total score was 0.82. In reliability test by internal consistancy, the Cronbach a coefficient of patient group was 0.85(p<0.05) and that of normal control was 0.84(p<0.05). The Concurrent validity between ADDES-HV scale and DSM- III -R scale was 0.57(p<0.05) in ADHD patient group and 0.84(p<0.05) in normal control group. In discriminant validity test between ADHD patient group and normal control, the ADHD patient group showed higher score(p<0.05). The total disciminant capacity of the patient group in ADDES-HV scale was 94.44%. When we regard the cut off point as standard deviation 1.5, the male student was 80 score and the female student was 69 score. In this point of view, ADDES-HV scale was proved to be the useful screening test tool for ADHD research and showed higher reliability and validity in applying to Korean subjects.
