Objectives：This study aimed to examine the validity scales of Minnesota Multiphasic Personality Inventory?2 Restructured Form (MMPI-2-RF) in Predicting premature termination and treatment duration in psychiatric outpatients.
Methods：The MMPI?2 was administered to 202 patients with psychiatric medication, and its data converted to MMPI-2-RF was used for analysis. An independent t-test used to determine whether there was a difference in validity scales between premature termination group and treatment continued group. Then, logistic regression analysis was performed to determine the degree of effect on premature termination. Moreover, correlation analysis and multiple regression analysis were performed to confirm the relationship between treatment duration and validity scales.
Results：The premature termination group showed higher score in variable response inconsistency (Vrin-r), adjustment validity (K-r) and lower score in infrequent responses (F-r) compared to the treatment continued groups. In logistic regression analysis, however, none of MMPI-2-RF validity scales predicted premature termination. Also, it was found that higher K-r score was associated with shorter treatment duration.
Conclusion：The study showed that the MMPI-2-RF validity scales can predict whether to continue medication and treatment. Therefore, it is expected that more thorough studies of the attitudes toward treatment with respect to the validity scales provides the opportunity to find patients at high risk of premature treatment prior to medication and to strengthen their motivation for treatment, thereby leading to more effective and lasting treatment.
