Psychological assessment research concerns how to describe psychological dysfunction in ways that are both valid and useful. Recent advances in assessment research hold the promise of facilitating significant improvements in description and diagnosis. One such contribution is in the classification of personality disorder symptomatology. The…

In this reply the authors address comments by C. R. Cloninger (2008) related to their report (R. F. Farmer & L. R. Goldberg, 2008) on the psychometric properties of the revised Temperament and Character Inventory (TCI-R) and a short inventory derivative, the TCI-140. Even though Cloninger's psychobiological model has undergone substantial…

Exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; S. O. Lilienfeld, 1990; S. O. Lilienfeld & B. P. Andrews, 1996) with a community sample has suggested that the PPI subscales may comprise 2 higher order factors (S. D. Benning, C. J. Patrick, B. M. Hicks, D. M. Blonigen, & R. F. Krueger, 2003). However,…

The development of Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) scales to measure the Personality Psychopathology Five (PSY-5), a model of personality, is reported. Preliminary scales were refined with the MMPI-A normative sample of 1,620 and a clinical sample of 713 adolescents, and their construct validity was supported. (SLD)

This study assessed the construct validity of the circumplex model of the Inventory of Interpersonal Problems (IIP-C) in Norwegian clinical and nonclinical samples. Structure was examined by evaluating the fit of the circumplex model to data obtained by the IIP-C. Observer-rated personality disorder criteria (DSM-IV, Axis II) were used as external…

The contributions of specific scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) to the classification of 180 adolescent substance abusers into groups characterized by aspects of behavioral control were studied. Seven scales made significant contributions to the classification of substance abusers into three groups, with…

Two personality models are compared regarding their relationship with personality disorder (PD) symptom counts and with lifetime Axis I diagnoses. These models share 5 similar domains, and the Big 7 model also includes 2 domains assessing self-evaluation: positive and negative valence. The Big 7 model accounted for more variance in PDs than the…

The Personality Psychopathology Five (PSY-5) is a dimensional descriptive system for personality and its disorders. The development of the scales, based on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), is described. Results with 3 clinical samples (total 1,680), a college sample of 2,928, and a normative sample of 2,567 support the…

Dimensional measures of aspects of personality disorders (PD) were developed. Convergence of these measures with the "Big Five" personality factors was studied in 300 general population subjects. Results suggest substantial similarity between the five factors and PD measures, though the latter cannot be entirely subsumed by the Big Five…

Reports on the psychometric properties of a new semistructured interview, the Structured Interview for the Five-Factor Model of Personality (T. Trull and T. Widiger, 1997). Data from clinical and nonclinical samples (187 undergraduates and 46 mental health outpatients) support the reliability and validity of the measure's scores. (SLD)

Longitudinal validity of Brief Symptom Inventory subscales was examined in a sample (N = 318) with schizophrenia-related illness measured at baseline and every 6 months for 3 years. Nonlinear factor analysis of items was used to test graded response models (GRMs) for subscales in isolation. The models varied in their within-time and between-times…

Thurstone's scaling based on judgments of 527 students and 37 clinical faculty members was applied to the Beck Depression Inventory, the Zung Depression Scale, and the Minnesota Multiphasic Personality Inventory and fitted the observed data well. A psychological continuum was derived for severity of depression. (SLD)
