Implementing Argument‐Based Validity in Second Language Research on Individual Differences

TESOL Quarterly, EarlyView.
Abstract Quantitative meta‐syntheses focusing on the psychometric properties of measurement tools in second and foreign language (L2) individual differences (ID) research have drawn scholars' attention to the quality of data collection instruments (Plonsky & Derrick, 2016; Sudina, 2023).

A Bifactor Approach to Modeling the Structure of the Psychopathy Checklist-Revised [PDF]

Journal of Personality Disorders, 2007
To date, models of the structure of psychopathy as assessed by the Psychopathy Checklist-Revised (PCL-R) have taken a higher-order approach in which the factors of the PCL-R are modeled as correlated elements of a higher-order psychopathy construct. Here, we propose an alternative structural model of the PCL-R, the bifactor model, which accounts for ...

Level‐specific reliability coefficients from the perspective of latent state‐trait theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The growing popularity of the ecological momentary assessment method in psychological research requires adequate statistical models for intensive longitudinal data (ILD), with multilevel latent state‐trait (ML‐LST) models based on the latent state‐trait theory revised (LST‐R theory) as one possible alternative.

Psychometric evaluation of the PCL-5: assessing validity, diagnostic utility, and bifactor structures

European Journal of Psychotraumatology
Background: The changes DSM-5 brought to the diagnostic criteria for posttraumatic stress disorder (PTSD) resulted in revising the most widely used instrument in assessing PTSD, namely the Posttraumatic Checklist for DSM-5 (PCL-5).Objective: This study ...

The General Psychopathology Factor: Structural Stability and Generalizability to Within-Individual Changes

Frontiers in Psychiatry, 2019
Objectives: Although cross-sectional investigations have found a bifactor structure of psychiatric comorbidity that includes a general psychopathology factor plus more specific factors, prospective evidence supporting the bifactor structure is still ...

Extending reliability to intensive longitudinal data with the Kalman filter

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is central to how researchers approach measurement in standard, group‐based analyses of single‐time‐point data, yet this critical aspect is often overlooked in the analysis of repeated observations. Since its inception, reliability has been a between‐person concept, but we redevelop this notion for within‐person designs by ...

Approximating multidimensionality with asymmetric unidimensional IRT models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Unidimensional item response theory (IRT) models are widely used even in settings where assessment data exhibit subtle forms of multidimensionality. Recent empirical evidence suggests that when item difficulty is associated with dimensionality, asymmetric item characteristic curves (ICCs) emerge in the unidimensional approximation.

External validation of a bifactor model of oppositional defiant disorder [PDF]

Molecular Psychiatry, 2018
AbstractDimensions of irritability and defiant behavior, though correlated within the structure of ODD, convey separable developmental risks through adolescence and adulthood. Irritability predicts depression and anxiety, whereas defiant behavior is a precursor to antisocial outcomes.
