Forced-choice Assessment of Maladaptive Traits 1 In press at Assessment Forced Choice Assessment of Work Related Maladaptive Personality Traits: Preliminary Evidence from an Application of Thurstonian Item Response Modeling

چکیده
This article describes an investigation of whether Thurstonian item response modeling is a viable method for assessment of maladaptive traits. Forced-choice responses from 420 working adults to a broad-range personality inventory assessing six maladaptive traits were considered. The Thurstonian item response model’s fit to the forced-choice data was adequate, while the fit of a counterpart item response model to responses to the same items but arranged in a single-stimulus design was poor. Mono-trait hetero-method correlations indicated corresponding traits in the two formats overlapped substantially, although they did not measure equivalent constructs. A better goodness of fit and higher factor loadings for the Thurstonian item response model, coupled with a clearer conceptual alignment to the theoretical trait definitions, suggested that the single-stimulus item responses were influenced by biases that the independent clusters measurement model did not account for. Researchers may wish to consider forced-choice designs and appropriate item response modeling techniques such as Thurstonian item response modeling for personality questionnaire applications in industrial psychology, especially when assessing maladaptive traits. We recommend further investigation of this approach in actual selection situations and with different assessment instruments.

متن کاملIntegration of the Forced-Choice Questionnaire and the Likert Scale: A Simulation Study
The Thurstonian item response theory (IRT) model allows estimating the latent trait scores of respondents directly through their responses in forced-choice questionnaires. It solves a part of problems brought by the traditional scoring methods of this kind of questionnaires. However, the forced-choice designs may still have their own limitations: The model may encounter underidentification and ...
متن کاملThe Role of Dimensional Maladaptive Personality Traits and Severity of Personality Pathology in the Prediction of Substance Use in an Iranian Mixed Sample
Background:In recent decades, the relationship between personality traits and attitudes toward substance use has attracted much attention, and research has shown that there is a significant direct relationship between personality factors and the tendency to substance use. However, the studies on the relationship between the PID-5 model, personality pathology, and tendency to addiction are scant...
متن کاملAn item response theory integration of normal and abnormal personality scales.
The Diagnostic and Statistical Manual of Mental Disorders (DSM–IV–TR) currently conceptualizes personality disorders (PDs) as categorical syndromes that are distinct from normal personality. However, an alternative dimensional viewpoint is that PDs are maladaptive expressions of general personality traits. The dimensional perspective postulates that personality pathology exists at a more extrem...
متن کاملDSM-5 alternative personality disorder model traits as maladaptive extreme variants of the five-factor model: An item-response theory analysis.
Over the past two decades, evidence has suggested that personality disorders (PDs) can be conceptualized as extreme, maladaptive variants of general personality dimensions, rather than discrete categorical entities. Recognizing this literature, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alternative PD model in Section III defines PDs partially through 25 ma...
