An Examination of the Reliability and Validity of the Comprehensive Assessment of Traits Relevant to Personality Disorder–Static Form (CAT-PD-SF)

Abstract

The current study examined the reliability and validity of the Comprehensive Assessment of Traits Relevant to Personality Disorder–Static Form (CAT-PD-SF), a dimensional measure of personality psychopathology. Specifically, we used exploratory factor analysis to determine the best higher order structure for the CAT-PD-SF traits. Results suggested a five-factor structure, albeit with marginal model fit. Second, we used correlation analyses to compare the CAT-PD-SF with two additional dimensional measures of personality, the Personality Inventory for DSM-5–Brief Form and the Five-Factor Model Rating Form. The results demonstrated the CAT-PD-SF scale scores were associated with domain and facet scores from these two models in a conceptually expected manner. Finally, we explored the association between the CAT-PD-SF scores and functional impairment and found moderate associations between CAT-PD-SF trait and functional impairment scores (as measured by the Measure of Disordered Personality Functioning Scale). Overall, findings add support to the structure of the CAT-PD model, and the use of the CAT-PD-SF in measuring dimensional personality psychopathology and impairment.

Pathological personality, situations, and their joint influences on daily emotional symptoms

“…The means of the CAT‐PD‐SF trait dimensions were reported in Table 1. To determine the extent this sample exhibited elevated pathological trait levels, these means were compared to a combined sample of college students and community adults (Long et al., 2021) and a sample of current or recent psychiatric patients (Williams & Simms, 2016). The current means showed less differences with the means from the psychiatric patients (i.e., d s < .20 for NA, DET, and ANT) but were higher compared to the student/community sample means (i.e., all d s > .20).…”

“…A few exceptions included (a) Fantasy proneness and Peculiarity loading onto NA rather than PSY, (b) Norm violation and Risk taking loading onto PSY rather than DIS, and (c) Non‐Perseverance, Perfectionism, and Workholism had cross loadings on domains other than DIS. Although these loadings were theoretically unexpected, past factor analytic studies have provided empirical evidence for them (see Crego & Widiger, 2016; Crego et al., 2018; Long et al., 2021; Thimm, 2020; Wright & Simms, 2014). Internal consistency reliabilities of the facet scales were good (mean = .83; ranged between .72 for Fantasy Proneness and .91 for Self‐Harm).…”

“…These studies also provided evidence for strong convergent and discriminant validity of the CAT‐PD‐SF in relation to PID‐5 and other inventories (see also Yalch & Hopwood, 2016). Factor analyses of CAT‐PD‐SF on its own have yielded a five‐factor structural model consistent with the AMPD, though there are some ambiguity in the placement of certain facets (Long et al., 2021; Thimm, 2020). Importantly, the CAT‐PD‐SF confers several advantages over the PID‐5, including a more comprehensive coverage of pathological traits and incremental validity in relevant criterion prediction (Simms et al., 2011; Yalch & Hopwood, 2016).…”

The use of MMPI-3 scales to assess personality-based vulnerabilities for alcohol use and problems.

“…Items are rated from 1 ( very untrue of me ) to 5 ( very true of me ). Subscales of the CAT-PD demonstrate acceptable reliability (McDonald’s ω ranges from .79 to .94; Long et al, 2021). The CMT construct of impulsivity explicitly incorporates acting on impulsive urges in light of strong emotional states (Finn, 2002), so we expected that it would be captured by CAT-PD Affective Lability, as it assesses a vulnerability to act impulsively in light of negative affective states.…”

Associations Between MMPI-3 Scale Scores and the DSM-5 AMPD and ICD-11 Dimensional Personality Traits

“…The overall AMPD and ICD-11 trait domain scores were calculated through the inclusion of all CAT-PD-SF trait scales relevant to each domain (see Table S3), as ascertained through facets included in the AMPD, ICD-11 criteria, and consultation of the CAT-PD literature on higher order structure (e.g., Long et al, 2021; Simms et al, 2011; Wright & Simms, 2014).…”
