본 연구에서는 MMPI-2와 MMPI-2-RF의 PSY-5 척도 점수를 비교한 뒤 PSY-5 성격모델에 비추어볼 때 성격장애 군집별 특징이 어떠한지 탐색하였다. 이후 두 개의 PSY-5 척도가 성격장애를 평가하는데 갖는 유용성을 비교해보았다. 성격장애로 진단받은 154명의 정신건강의학과 환자중 A, B, C 성격장애군으로 진단된 환자들(각 군집별 54, 59, 41명)의 PSY-5 점수들을 다변량분석과 사후분석으로 분석하였다. 그 결과, MMPI-2와 MMPI-2-RF 모두 PSY-5 중 내향성 척도를제외한 모든 하위 척도에서 세 군집 간에 유의한 차이를 보였다. 사후분석에서 B군은 C군에 비해AGGR(AGGR-r), PSYC(PSYC-r) 척도 점수가 유의하게 높았고 A군과 C군에 비해 DISC (DISC-r), NEGE(NEGE-r) 척도 점수가 유의하게 높았다. 또한 C군은 MMPI-2에서만 DISC 점수가 A군보다 유의하게 낮았다. MMPI-2-RF의 PSY-5는 MMPI-2의 PSY-5보다 적은 문항으로 유사한 수준의 성격병리적 정보를 제공할 수 있을 것으로 시사된다. 연구의 한계점과 후속 연구를위한 제안 등이 논의되었다.
The purpose of this study was to compare the clinical utility of the PSY-5 scales in the MMPI-2-RF and MMPI-2. According to the DSM-IV-TR, the sample consisted of cluster A, B and C personality disorder groups (N = 154). The results, based on multivariate ANOVAs showed that there were significant differences among the groups in the scales except for INTR (INTR-r). Post hoc analyses, Scheffe's and Dunnett's tests, revealed that cluster B scored higher than cluster C in AGGR (AGGR-r) and PSYC (PSYC-r). The scores of DISC (DISC-r) and NEGE (NEGE-r) in cluster B were higher than those of other groups. The results of the two PSY-5 scales were generally similar, but cluster C scored lower than cluster A in DISC of MMPI-2. The results suggest that the PSY-5 scale in the MMPI-2-RF can measure clinical range personality as much as the PSY-5 in the MMPI-2 with fewer questions. Implications and limitations of these findings are also discussed.
