  • Validation of the Hierarchical Taxonomy of Psychopathology Brief Report (HiTOP-BR) in Two German-Speaking Samples

    Open AccessJonas Schmitt, Matthias Volz et al.ARTICLEJournal of Personality Assessment2026

    601). Confirmatory factor analyses and exploratory factor analyses with target rotation supported the hypothesized six-factor structure across both samples, although observed cross-loadings suggested scope for item refinement. Scalar measurement invariance was established between the clinical and nonclinical samples. Scale scores showed acceptable to good reliability (ω = .77-.88). Convergent and discriminant validity were examined via correlatio…

  • CAT-PD and MMPI-3 Validity Scales Detect Simulated Overreporting and Underreporting

    Omeed Tartak, Leah T Emery et al.ARTICLEJournal of Personality Assessment2025

    Individuals can sway legal, medical, employment, or other decisions by dishonestly self-reporting on psychological tests. Accordingly, the Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD) and the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) include validity scales to detect overreporting and underreporting. Although many studies have empirically tested the validity scales of the MMPI-2 and the MMPI-2-RF, fewe…

  • Understanding the association between normal and maladaptive personality traits

    Open AccessLeah T Emery, Chloe M Evans et al.ARTICLEJournal of Personality2024

    BACKGROUND/OBJECTIVE: The Alternative Model for Personality Disorders (AMPD) within the DSM-5 includes separable components representing general personality dysfunction (Criterion A) and maladaptive personality traits (Criterion B). Some critique Criterion A for accounting for little incremental variance in PD beyond Criterion B. However, Morey et al. (2020) hypothesized that personality dysfunction is a key mechanism through which normal-range t…

  • A Peer Trade-off Model of Personality Disorder Traits During Adolescence

    Jenna P Weingarten, Julie C Bowker et al.ARTICLEInternational Journal of…2024

    This Viewpoint paper argues for a peer trade-off model of personality disorder (PD) traits during adolescence that allows for both positive (e.g., popularity, peer acceptance) and negative (e.g., peer rejection, peer victimization, peer exclusion) peer outcomes. The need for new interpersonal (dsy)function models of PD traits during adolescence is urgent because most research has focused on internalizing and externalizing psychopathology, as well…

    Version IV, Narcissistic Admiration and Rivalry Questionnaire-Short Form, Single-Item Narcissism Scale, and brief version of the Pathological Narcissism Inventory). The findings of Study 1 (N = 5,736) revealed heterogeneity in how strongly the measures are correlated. Some instruments loaded clearly on one of the three factors proposed by previous research (i.e., Neuroticism, Extraversion, Antagonism), while others cross-loaded across factors and…

  • Does the number of response options matter? Psychometric perspectives using personality questionnaire data.

    Open AccessLeonard J Simms, Kerry Zelazny et al.ARTICLEPsychological Assessment2019

    Psychological tests typically include a response scale whose purpose it is to organize and constrain the options available to respondents and facilitate scoring. One such response scale is the Likert scale, which initially was introduced to have a specific 5-point form. In practice, such scales have varied considerably in the nature and number of response options. However, relatively little consensus exists regarding several questions that have e…

  • Personality traits and maladaptivity

    Open AccessTrevor F Williams, Leonard J SimmsARTICLEJournal of Personality2018

    OBJECTIVE: Dimensional personality trait models have gained favor as an alternative to categorical personality disorder (PD) diagnosis; however, debate persists regarding whether these traits should be conceptualized as maladaptive at both extremes (i.e., maladaptively bipolar) or just one trait pole (i.e., unipolar). METHOD: To inform the debate on maladaptive bipolarity, linear and nonlinear relations between personality traits and dysfunction …

  • Clarifying the Links of Conscientiousness With Internalizing and Externalizing Psychopathology

    Open AccessKristin Naragon-Gainey, Kristin Naragon‐Gainey et al.ARTICLEJournal of Personality2017

    OBJECTIVE: Although Conscientiousness/disinhibition plays a substantial role in internalizing and externalizing psychopathology, the underlying mechanisms are not well understood. We aim to clarify facet-level associations and to examine whether (a) impairment mediates the link of Conscientiousness with internalizing and externalizing symptoms, and (b) demoralization (assessed via Neuroticism) accounts for their associations. METHOD: = 42; primar…

  • Psychometric properties of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA)

    Daniel F Gros, Martin M Antony et al.ARTICLEPsychological Assessment2007

    The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; M. J. Ree, C. MacLeod, D. French, & V. Locke, 2000) was designed to assess cognitive and somatic symptoms of anxiety as they pertain to one's mood in the moment (state) and in general (trait). This study extended the previous psychometric findings to a clinical sample and validated the STICSA against a well-published measure of anxiety, the State-Trait Anxiety Inventory (STAI; C…

  • Development and validation of the Inventory of Depression and Anxiety Symptoms (Idas).

    David Watson, David C Watson et al.ARTICLEPsychological Assessment2007

    The authors describe a new self-report instrument, the Inventory of Depression and Anxiety Symptoms (IDAS), which was designed to assess specific symptom dimensions of major depression and related anxiety disorders. They created the IDAS by conducting principal factor analyses in 3 large samples (college students, psychiatric patients, community adults); the authors also examined the robustness of its psychometric properties in 5 additional sampl…

  • The Big Seven Model of Personality and Its Relevance to Personality Pathology

    Open AccessLeonard J SimmsARTICLEJournal of Personality2007

    Proponents of the Big Seven model of personality have suggested that Positive Valence (PV) and Negative Valence (NV) are independent of the Big Five personality dimensions and may be particularly relevant to personality disorder. These hypotheses were tested with 403 undergraduates who completed a Big Seven measure and markers of the Big Five and personality pathology. Results revealed that PV and NV incrementally predicted personality pathology …
