The structure of dimensions of psychopathology in normative and clinical samples: Applying causal discovery to MMPI-2-RF scales to investigate clustering of psychopathology spectra and -factors.

We applied a Bayesian Constraint-based Causal Discovery method (BCCD) to examine the hierarchical structure of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) Restructured Clinical (RC) scales. Two different general psychopathology super spectra (-factor) scales were extracted from (1) all RC scales and (2) all RC scales except the RCd (Demoralization) scale. These -factor scales were included in separate models to investigate the structure of dimensions of psychopathology in a normative ( = 3,242) and clinical ( = 2,466) sample, as well as the combined normative/clinical sample ( = 5,708), by applying the BCCD algorithm to obtain a data-driven reconstruction of the internal hierarchical structure of the MMPI-2-RF.

Robustness of the Maladaptive Personality Plaster: An Investigation of Stability of the PSY-5-r in Adults over 20 Years.

The long-term stability of maladaptive personality traits in the general population has been under-investigated. The current study examined the longitudinal 20-year mean-level stability and rank-order consistency of five maladaptive personality traits-as measured with the Personality Psychopathology-5-r scales. Correlations and regression analysis were conducted to test both types of stability comparing raw scores of scale administrations in a general population sample in both 1992 and 2012 ( = 65).
