Minnesota Multiphasic Personality Inventory‐Adolescent‐Restructured Form (MMPI‐A‐RF) characteristics of ADHD in a Korean psychiatric sample

Abstract

Global rates of attention-deficit/hyperactivity disorder (ADHD) have risen. In Korea, ADHD is associated with functional impairments and comorbidity with other psychological disorders. This study examined the correlates of ADHD in a psychiatric sample of Korean adolescents on the Minnesota Multiphasic Personality Inventory-Adolescent-Restructured Form (MMPI-A-RF). In a clinical sample of 247 adolescents, MMPI-A-RF scores from 46 patients diagnosed with ADHD were compared to the remainder of the clinical sample and to the Korean MMPI-A-RF norms. Results demonstrated significantly different scores for the ADHD group on scales indicating externalizing concerns and behavior dysfunction compared with the clinical group with other disorders and to a normative sample. Notable differences were also observed between clinical groups on scales reflecting interpersonal functioning. Relative risk ratio analyses demonstrated that an MMPI-A-RF T-score of 55 was generally most effective for predicting risk for an ADHD diagnosis in the clinical sample.

Clinical Utility of the Minnesota Multiphasic Personality Inventory-Adolescent Restructured Form in the Assessment of Internalizing and Externalizing Disorders in Adolescents: A Preliminary Approach

“…Regarding the scales associated with externalizing disorder, our study showed higher scores on the Externalizing Scales (CNP and NPI) in the externalizing group. Among the five main domains, the externalizing problem is related to the Behavioral Dysfunction domain of the MMPI-A-RF [ 22 ]. Furthermore, in a recent MMPI-A-RF study on ADHD, which is the most typical externalizing disorder, an ADHD group reported significantly different scores on scales indicating externalizing concerns and behavioral dysfunction compared with a non-ADHD group [ 22 ].…”

The findings of the present study, which showed significantly higher CNP and NPI scores in the externalizing disorder group, are consistent with those of Chakranarayan et al [ 22 ], demonstrating that the BXD, RC4, CNP, NPI, and DISC-r scales have diagnostic relevance for ADHD.…”

In another study by Fertitta [ 23 ], the externalizing disorder group showed significantly higher scores than the internalizing disorder group on BXD, Antisocial Attitudes, CNP, SUB, AGG, DISC-r, and AGGR-r.…”
