Examining the Internal Structure of the Korean MMPI-2-RF Specific Problems Scales with the Korean Adult Psychiatric and Normative Samples

A central feature of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) is its hierarchical structure, which links to contemporary models of psychopathology. Sellbom (2017) recently showed that the hierarchical structure can be recovered by factor analyses of the MMPI-2-RF SP and interest scales, which produce four factors representing: internalizing, externalizing, interpersonal detachment, and somatization. Extending this work with the Korean MMPI-2-RF, the present study aims to examine the internal structure of the SP and Interest scales in Korean adult clinical (<i>n</i> = 394) and normative (<i>n </i>= 1,287) samples.<br> <br>Using the same analytic strategies (maximum likelihood estimation and geomin oblique rotation), we will extract four factors to examine whether the four-factor model previously identified is robust in the Korean samples. If the four-factor model is judged to be inadequate, multiple extraction and rotation methods will be employed to identify an optimal factor model for the Korean samples. Second, the working model (Sellbom, 2019) that linked the MMPI-2-RF scales to the HiTOP (Hierarchical Taxonomy of Psychopathology; Kotov et al., 2017) structure will be tested using the SP scales, RC6, and RC8 via a series of confirmatory analyses (CFA).
