Criterion A of the DSM-5 Alternative Model for Personality Disorders in MMPI-2/RF Personality Disorder Scales

The Minnesota Multiphasic Personality Inventory (MMPI) instruments are frequently used to assess personality and psychopathology. Recent publications of personality disorder (PD) spectra scales for dimensionalized PD syndromes with MMPI instruments may advance PD assessment. To this end, we examined MMPI-Second Edition (2) and MMPI-2-Restructured Form (-RF) PD Spectra scales within the lens of a contemporary dimensional model of PDs, the alternative model for personality disorders (AMPD). The core dimension of PD, Criterion A of the AMPD or level of personality functioning (LPF), was characterized quantitatively within the PD Spectra scales. By sequentially factor analyzing the scales of the Severity Indices of Personality Problems (SIPP-118) to a common general factor of PD, an index of LPF external to the MMPI item pool was established. This LPF dimension was strongly represented across most PD Spectra scales. LPF variances within the PD Spectra scales were deconstructed using measures of general demoralization (RCdemoralization) and maladaptive personality traits indexed by the Personality Psychopathology-5 (PSY-5). Nuanced LPF and PD Spectra scale relationships were discerned. Dimensionalized Antisocial PD, Borderline PD, Dependent PD, and Paranoid PD showed meaningful association with LPF after demoralization, and maladaptive trait variances were removed. The examination of the MMPI-3 item pool reveals that the existing PD Spectra scale item sets are largely carried forward in the new edition of the MMPI. This suggests PD Spectra scale correlates, including LPF relationships, may be discernable in the newest edition of the MMPI, pending future study.

Five Factor Model and Personality Disorder

The purpose of this chapter is to provide an overview of the relationship of the Five Factor Model (FFM) to personality disorder. The FFM has traditionally been viewed as a dimensional model of normal personality structure. However, it should probably be viewed as a dimensional model of general personality structure, including maladaptive as well as adaptive personality traits. Discussed herein is the empirical support for the coverage of personality disorders within the FFM; the ability of the FFM to explain the convergence and divergence among personality disorder scales; the relationship of the FFM to the DSM-5 dimensional trait model; the empirical support for maladaptivity within both poles of each FFM domain (focusing in particular on agreeableness, conscientiousness, and openness); and the development of scales for the assessment of maladaptive variants of the FFM.

Reciprocal interaction between sexuality and personality: parallel assessment of patients with QSAF- 2009 and MCMI-III

ObjectiveTo evaluate mutual interaction between sexuality and personality we tried to study 111 patients with QSAF 2009 and MCMI-III.MethodsHundred and eleven consecutive patients with sexual problems (76) or personality disorders (35) were examined with two tests. Only volunteer personality disorder patients were enrolled to this trial. The results were compared with 325 examinees evaluated with QSAF and 1600 patients evaluated with MCMI-III.ResultsAll patients with sexual problems showed at least two scores higher than 72 in their MCMI-III. This was more prominent in sexual deviations than dysfunctions. Homosexuals had higher scores in schizoid and schizotypal, pedophiles in schizoid and antisocial, voyeurs in schizoid and avoidant, masochists in dependent and self defeating personality scales …. Sexually deviated persons remain clinically latent and show themselves as alien, aloof and eccentric. Almost all deviated persons show high scores in personality disorder scales. On the contrary, only a minority of personality disorder patients show prominent sexual problems in the form of deviation. They predominantly have disturbed sexual self image, show inhibited sexual desire problems (dependent, schizoid and avoidant) personality, dyspareunia and vaginism (avoidant and schizotypal personality), spouse abuse (borderline and antisocial personality) postcoital disorders (borderline, dependent and narcissistic personality) and extramarital relationship in a series of disorders including histrionic personality …. as studied by the QSAF 2009 which evaluates 64 sexual scales.ConclusionEvaluation of personality disordered patients in regard to sexuality and vice versa is essential for better understanding the pathogenesis of each disease and helps in smoother treatments.
