The Personality Inventory for ICD-11 (PiCD) was recently developed to assess the ICD-11 model of personality disorders. The purpose of this study was to examine the construct validity of the PiCD using the Minnesota Multiphasic Personality Inventory (MMPI)-2-Restructured Form (MMPI-2-RF) and the Computerized Adaptive Test of Personality Disorders Static Form (CAT-PD-SF). We administered these tests to 328 college students (150 males, 178 females). We found that the PiCD had adequate internal consistency reliability. Correlations between scores from the PiCD scales and the criterion measures generally indicated adequate discriminant validity. Along the same lines, convergent validity was adequate for the PiCD Negative Affective, Disinhibition, and Dissocial scales. However, the evidence was more mixed for the PiCD Detachment and Anankastic domains, which may be due to limitations with the content domains for these scales. Consistent with other research and theoretical expectations, a conjoint exploratory factor analysis utilizing the PiCD and MMPI-2-RF PSY-5 scales also indicated that anankastic and disinhibition may be more appropriately conceptualized as measuring opposite poles of one construct. Implications of these findings for the PiCD and the ICD-11 model are discussed. [ABSTRACT FROM AUTHOR]

To assess the psychometric properties of the Personality Inventory for ICD-11 (PiCD, where ICD-11 is the International Classification of Diseases, 11th Revision), a sample of Italian community-dwelling adult participants (N = 1,122) was administered the PiCD, the Five-Factor Model Rating Form, the Big Five Inventory, the Personality Inventory for DSM-5 Short Form (where DSM-5 is the Diagnostic and Statistical Manual of Mental Disorders, fifth edition), and the Measure of Disordered Personality Functioning. Our findings supported the unidimensionality hypothesis for the PiCD Negative Affectivity, Detachment, and Dissocial scale items, whereas adequate fit indices were observed for the bifactor model of the PiCD Disinhibition and Anankastic item joint polychoric correlation matrix. The PiCD scales showed adequate internal consistency, test-retest reliability (n = 262), and meaningful relationships with five-factor model domains and their maladaptive variants. A four-factor model of the joint correlation matrix of the PiCD, Personality Inventory for DSM-5 Short Form, and the five-factor model composite score was provided with adequate fit. All PiCD scales were significantly associated with the impairment in personality functioning. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The International Classification of Diseases, 11th edition (ICD-11) adopted a fully dimensional model of personality disorder. The Personality Inventory for ICD-11 (PiCD) and Informant-Personality Inventory for ICD-11 (IPiC) were developed to assess the ICD-11 trait model, and the PiCD has since received significant validation support. However, there has only been one prior study of longitudinal predictive validity of the PiCD, two relatively short test–retest reliability studies of the PiCD, and no prior longitudinal tests of the IPiC. Longitudinal psychometric support for psychological assessment measures is essential. The present study provides a longer, larger, 2-year psychometric validation test of the PiCD and IPiC. Participants (N = 711) and their informants (N = 569) were recruited in the St. Louis Personality and Aging Network. The results demonstrated strong 2-year retest reliability for the PiCD and IPiC, as well as mean-level stability. Additionally, we explored the relationships between the PiCD and IPiC and important life outcome measures (depressive symptoms, satisfaction with life, and health status). The analysis revealed several significant associations between PiCD and IPiC scales and the outcome variables across time. Further, the PiCD Negative Affectivity and IPiC Detachment scales demonstrated incremental validity over each other and the outcome variables at Wave 1 in the prediction of depressive symptoms and satisfaction with life, respectively. The findings provide essential longitudinal test–retest reliability and predictive validity support for the PiCD and IPiC. Public Significance Statement: This 2-year study on the Personality Inventory for ICD-11 (PiCD) and Informant-Personality Inventory for ICD-11 (IPiC) highlights robust retest reliability for both scales in a sample of older community adults. Evidence is also found for mean-level stability and associations between the scales and depressive symptoms, satisfaction with life, and health status. This research provides essential, foundational longitudinal psychometric support for both the PiCD and IPiC scales. [ABSTRACT FROM AUTHOR]

The International Classification of Diseases-11th Edition (ICD-11) includes a dimensional trait model of personality disorder. The Personality Inventory for ICD-11 (PiCD) was the first self-report measure developed for its assessment. The present study examines the validity of an informant-report version of the PiCD, the Informant-Personality Inventory for ICD-11 (the IPiC), and is the first study to test self–other agreement, ratings from close others, and the criterion validity of both the IPiC and the PiCD for several popular and well-validated measures of life functioning: Life and romantic relationship satisfaction, social support, physical and mental health, depressive symptoms, insomnia symptoms, and cognitive decline. The present study is also the first to examine the IPiC and PiCD in a sample of older adults in the community. Results suggest that the IPiC and the PiCD show moderate self–other agreement, are associated significantly with several important life functioning areas, and have structural validity even at the item level. Further replication and validation are necessary for these instruments, but the IPiC and the PiCD have shown strong validation evidence to date, now including evidence of consensual and criterion validity, in addition to structural validity. Public Significance Statement: This study provides convergent, criterion, and structural validity for the self-report and informant-report Personality Inventories for ICD-11. It further shows that the ICD-11 personality traits are associated with important life variables. [ABSTRACT FROM AUTHOR]

A central innovation in the International Classification of Diseases 11th Revision (ICD-11) is a dimensional personality disorder model differentiating five personality trait domains. The Personality Inventory for ICD-11 (PiCD) is a frequently used measure to assess these components of the ICD-11 personality disorder model. Conceptually, the ICD-11 personality trait domains correspond to trait domains from the five-factor model (FFM) of personality. However, empirically, it is unclear how the PiCD scales align with the FFM. In this questionnaire study with 480 German community adults, we assessed the joint factor structure of the PiCD trait domain scales and the FFM personality facets (assessed with the Big Five Inventory-2 [BFI-2]). A principal axis factor analysis revealed a joint five-factorial structure. The PiCD trait domain scales and the BFI-2 facet scales of the respectively corresponding FFM trait domains were almost perfectly aligned, including a bipolar anankastia–disinhibition factor along the conscientiousness dimension. Facets of openness to experience formed a fifth factor, separate from the PiCD scales. Together, these findings demonstrate structural correspondences of the PiCD trait domain scales and the respective BFI-2 facet scales, mirroring conceptual analogies between the ICD-11 and FFM personality models. Public Significance Statement: The study suggests that the Personality Inventory for ICD-11 (PiCD) aligns with the five-factor model (FFM) of personality. Thus, the PiCD appears to reflect theoretically postulated correspondences between the FFM and the ICD-11 personality disorder model, which supports the validity of the PiCD trait domain scores for assessing the ICD-11 personality trait domains.

The International Classification of Diseases-11th Edition (ICD-11) Classification of Personality Disorders provides the option of coding 5 trait domain qualifiers that contribute to the individual expression of personality dysfunction (i.e., Negative Affectivity, Detachment, Dissociality, Disinhibition, and Anankastia). Previous investigations of these trait domains are based on self-reported data, and so is much of the research literature from which the ICD-11 trait model has evolved. However, the ICD-11 itself involves judgments made by clinicians about their patients. Thus, it is important to examine whether the trait domains identified in self-report studies can also be obtained from clinician-reported data. A sample of 238 mental health patients were characterized by clinicians using an informant-report form of the Personality Inventory for ICD-11 (PiCD-IRF). As expected, exploratory factor analysis (EFA) indicated that clinician-reported ICD-11 trait domains could be captured by both 4- and 5-factor structures, of which the 5-factor solution seemed less conceptually sound relative to the 4-factor solution. The 4-factor model captured the unipolar domains of Negative Affectivity, Detachment, Dissociality, along with a bipolar domain of Disinhibition versus Anankastia, whereas the 5-factor model furthermore captured features of Disinhibition and Anankastia as 2 separate factors. The hierarchical structure from 1 to 5 factors partially resembled previously reported trait structures and models of psychopathology. These findings overall support the multimethod robustness of ICD-11 trait domain qualifiers and the potential for their valid ratings by mental health clinicians. The PiCD-IRF is provided in the online supplementary material - for clinical or research purposes. (PsycINFO Database Record (c) 2019 APA, all rights reserved). [ABSTRACT FROM AUTHOR]

At present, there are two models of pathological personality represented in two measurement instruments, the Personality Inventory for DSM-5 (PID-5) and the Personality Inventory for ICD-11 (PiCD). Although both instruments have shown high convergence, the PID-5 has the advantage of including facets that might offer greater predictive capacity. An alternative to the PiCD has recently been proposed to overcome this drawback, namely the Five-Factor Personality Inventory for ICD-11 (FFiCD). The present study aims to explore its internal structure and to offer additional validity evidence. Data were collected for a total of 1,409 community individuals from two populations in Spain. They responded to the FFiCD, PiCD, the PID-5/SF, and measures of personality functioning and personality disorder screening (Level of Personality Functioning Scale Self-Report [LPFS-SR] and International Personality Disorder Examination [IPDE]). The internal structure of the FFiCD was analyzed through exploratory factor analysis with oblique and bifactor rotations. The predictive capacity of the domains and facets was examined. The structure reported in the original study was replicated, as were the convergent validity data with respect to the PID-5/SF and the PiCD. Facets were grouped into four factors corresponding to the theoretical domains, including a bipolar Anankastia/Disinhibition factor. High correlations were found with the LPFS-SR, and the patterns of relationships with the IPDE shed light on which aspects of pathological personality contribute most to the 10 traditional personality disorders. In general, validity evidence is provided to support the use of the FFiCD, though four of the 20 facets merit revision so that a simpler factor structure can be obtained. Public Significance Statement: The present study investigated the internal structure of the FFiCD in a large sample and sought to provide additional validity evidence using the PiCD, the PID-5/SF, LPFS-SR, and a measure for screening personality disorders (IPDE). The results support the use of the FFiCD, although four of the 20 facets could be revised for enhanced performance. [ABSTRACT FROM AUTHOR]

The ICD-11 model of personality disorder consists of a level of severity, 5 trait domains, and a borderline pattern qualifier. Level of severity is assessed by the Standardized Assessment of Severity of Personality Disorder (SASPD; Olajide et al., 2018), the trait model by the Personality Inventory for ICD-11 (PiCD; Oltmanns & Widiger, 2018), and the borderline pattern qualifier by the Borderline Pattern Specifier inventory (BPS; Oltmanns & Widiger, 2019). The DSM-5 Section III Alternative Model of Personality Disorder includes a level of personality functioning and the five-domain trait model. These two components are assessed by the Level of Personality Functioning Scale (LPFS; Morey, 2017) and the Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012). Components of each model have been related to one another, but no study has yet considered all of the components for both models within one study. The current study considers the convergent, discriminant, and structural validity of the relationship of the LPFS and PID-5 with the SASPD, PiCD, and BPS. Also included were multiple measures of borderline personality disorder to determine if the BPS obtains incremental validity in accounting for borderline personality disorder variance above and beyond the trait models.

The predominant maladaptive trait models are now provided by Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) Section III, assessed by the Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012), and the International Classification of Diseases-11th Revision (ICD-11; assessed by the Personality Inventory for ICD-11 (PiCD; Oltmanns & Widiger, 2018). However, 2 historical precedents are the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley & Jackson, 2009) and the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993). The current study administered the DAPP-BQ, SNAP, PiCD, and PID-5 to a sample of 323 persons with a history of mental health treatment. The results provided support for the historical precedence of the DAPP-BQ and SNAP, although also suggest that additional traits should perhaps be included in current models. The results also bear on additional ongoing issues, including (but not limited to) the bipolarity of maladaptive personality structure, the conceptualization of identity problems as a trait, and the discriminant validity of maladaptive trait models and their assessment.

The 11th edition of the International Classification of Diseases and Related Health Problems (ICD-11), recently approved by the World Health Organization, contains a new diagnostic approach for personality disorders. This approach partly involves the consideration of 5 dimensional trait domain qualifiers-Negative Affectivity, Detachment, Dissocial, Disinhibition, and Anankastia. Oltmanns and Widiger (2018) recently developed a self-report measure, the Personality Inventory for ICD-11 (PiCD), to assess the 5 domains; however, further examination of the psychometric properties of the PiCD is warranted due to its limited research base. The present study aimed to further examine the reliability, structural and concurrent validity, and method variance of the PiCD in an ethnically diverse undergraduate sample (N = 518), who were also administered the Minnesota Multiphasic Personality Inventory-2-Restructured Form. First, results suggested that the PiCD domain scales exhibited adequate internal consistency reliability via coefficient categorical omega (range = .77-.87). Next, exploratory structural equation modeling results suggested support for a 4-factor solution, with the 4th factor thought to represent a bipolar continuum of Anankastia to Disinhibition severity. Random-intercept factor analysis results suggested a small amount of variance in items (4.88%) attributable to idiosyncratic scale usage. Lastly, relations between PiCD domains and Minnesota Multiphasic Personality Inventory-2-Restructured Form scales (Personality Psychopathology-5 and Higher Order scales) provided support for the validity of the Negative Affectivity, Detachment, and Dissocial domains, though relatively less support for the Disinhibition and Anankastia domains. Further examination of other psychometric properties and the nomological network of the PiCD is recommended. (PsycINFO Database Record (c) 2019 APA, all rights reserved). [ABSTRACT FROM AUTHOR]

Proposed for the ICD-11 is a dimensional model of personality disorder that, if approved, would be a paradigm shift in the conceptualization of personality disorder. The proposal consists of a general severity rating, 5 maladaptive personality trait domains, and a borderline pattern qualifier. The general severity rating can be assessed by the Standardized Assessment of Severity of Personality Disorder (SASPD), the trait domains by the Personality Inventory for ICD-11 (PiCD), and the borderline pattern by the Borderline Pattern Scale (BPS), which is developed in the present study. To date, no study has examined the relations among all 3 components, due in part to the absence of direct measures for each component (until recently). The current study develops and provides initial validation evidence for the BPS, and examines the relations among the BPS, SASPD, and PiCD. Also considered is their relationship with the 5-factor model of general personality as well as with 2 other measures of personality disorder severity (including the DSM-5 Level of Personality Functioning Scale [LPFS]). Further, an alternative trait-based coding of the DSM-5 LPFS is examined (modeled after the ICD-11 SASPD), suggesting that its coverage of diverse maladaptivity may not be because it assesses the core of personality disorder, but rather because it has items specific to the different domains of personality.

Proposed for the 11th edition of the World Health Organization's International Classification of Diseases (ICD-11) is a dimensional trait model for the classification of personality disorder (Tyrer, Reed, & Crawford, 2015). The ICD-11 proposal consists of 5 broad domains: negative affective, detachment, dissocial, disinhibition, and anankastic (Mulder, Horwood, Tyrer, Carter, & Joyce, 2016). Several field trials have examined this proposal, yet none has included a direct measure of the trait model. The purpose of the current study was to develop and provide initial validation for the Personality Inventory for ICD-11 (PiCD), a self-report measure of this proposed 5-domain maladaptive trait model. Item selection and scale construction proceeded through 3 initial data collections assessing potential item performance. Two subsequent studies were conducted for scale validation. In Study 1, the PiCD was evaluated in a sample of 259 MTurk participants (who were or had been receiving mental health treatment) with respect to 2 measures of general personality structure: The Eysenck Personality Questionnaire-Revised and the 5-Dimensional Personality Test. In Study 2, the PiCD was evaluated in an additional sample of 285 participants with respect to 2 measures of maladaptive personality traits: The Personality Inventory for DSM-5 and the Computerized Adaptive Test for Personality Disorders. Study 3 provides an item-level exploratory structural equation model with the combined samples from Studies 1 and 2. The results are discussed with respect to the validity of the measure and the potential benefits for future research in having a direct, self-report measure of the ICD-11 trait proposal.
