Objective:
The purpose of the present study was to compare psychometric properties of the Substance Abuse (SUB) Scale on the Korean Minnesota Multiphasic Personality Inventory-Adolescent-Restructured Form (MMPI-A-RF) with those on the Korean MMPI-A (the Alcohol/Drug Problem Acknowledgment Scale [ACK]), the Alcohol/Drug Problem Proneness Scale [PRO], and the MacAndrew Alcoholism Scale-Revised Scale [MAC-R]).
Method:
Participants consisted of 237 Korean adolescent psychiatric patients whose scores on these measures were compared in terms of internal consistency and predictive validity.
Results:
Scores on SUB exhibited superior internal consistency to that of the MMPI-A substance abuse scales. Further, scores on SUB predicted substance abuse more accurately than did the optimal combination of scores on the MMPI-A substance abuse scales.
Conclusion:
Results provide strong support for the use of the Korean MMPI-A-RF SUB scale when assessing substance abuse in Korean youth.
