Assessing Criterion A in adolescents using the Semistructured Interview for Personality Functioning DSM–5.

Accumulating evidence supports the reliability and validity of the diagnosis of personality disorders (PDs) in adolescents, but whether the current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), criteria are optimal to capture and help detect emerging PDs in this age-group remains controversial. The Level of Personality Functioning Scale (LPFS), included in the alternative model for personality disorders, may provide a more developmentally sensitive way to identify impaired personality features in young people. This study investigates the feasibility of the LPFS in adolescents by examining the psychometric properties of the Semistructured Interview for Personality Functioning DSM-5 in a clinical sample of referred adolescents (N = 84) and in a community sample (N = 12). Additionally, referred adolescents completed self-report questionnaires pertaining to symptom severity, personality functioning, and personality traits. In general, good interrater reliability and internal consistency were observed, and the associations with external variables largely followed theoretical prediction. Interestingly, and in contrast to data on adults, we found no significant associations between the LPFS scores on the one hand and traditional DSM-5 PD diagnoses in the clinical sample on the other (except for borderline PD criteria). In discussing these findings, we argue that the assessment of personality functioning may be better suited for detecting personality pathology in adolescence than the traditional Section II criteria.

Social impairment and personality disorder features among older adults: An application of the circumplex model.

The interpersonal circumplex is a model that places interpersonal problems along two axes (communion and agency), resulting in eight theoretically derived patterns. Application of the circumplex to older adults is poorly understood. Subsequently, this study examined relationships between the interpersonal circumplex and personality disorder (PD) features among older adults, since social impairments are core components of PDs. Two models of PDs were examined: the traditional model of 10 PDs and the Alternative Model of PDs (AMPD) with its personality functioning and pathological personality trait features. Older adults (N = 202) completed the Inventory of Interpersonal Problems-Short Circumplex, Coolidge Axis II Inventory, Levels of Personality Functioning Scale-Self-Report, and Personality Inventory for DSM-5. Overlap between the interpersonal circumplex and PD features were detected, but patterns were distinct from prior studies with younger samples. Cluster B and C PD features showed meaningful relationships, whereas Cluster A did not. The circumplex was limited in its relation to the AMPD's personality functioning. The communion component of the circumplex significantly related to the AMPD's pathological trait model, whereas the agency component was limited in its association with pathological traits. Overall, the circumplex meaningfully related to PD features across two different PD models, providing some evidence of validity.

Analysis of the interaction between personality dysfunction and traits in the statistical prediction of physical aggression: Results from outpatient and community samples.

The Alternative Model for Personality Disorders (AMPD), included in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and the World Health Organization's International Classification of Diseases (11th ed.; ICD-11) are, respectively, hybrid categorical-dimensional and dimensional frameworks for personality disorders (PDs). Both models emphasize personality dysfunction and personality traits. Previous studies investigating the links between the AMPD and ICD-11, and self-reported physical aggression have mostly focused on traits and did not take into account the potential interaction between personality dysfunction and traits. Thus, the aim of this study is to identify dysfunction*trait interactions using regression-based analysis. Outpatients with personality disorder from a specialized public clinic (N = 285) and community participants (N = 995) were recruited to complete self-report questionnaires. Some small-size, albeit significant and clinically/conceptually meaningful personality dysfunction*trait interactions were found to predict physical aggression in both samples. Interaction analyses might further inform, to some degree, about the current discussion pertaining to the potential redundancy between dysfunction and traits, the optimal personality dysfunction structure (in the case of the AMPD), as well as clinical assessment based on AMPD/ICD-11 PD frameworks.

The “Lost” Personality Disorders and Their Relationships to the Alternative Model of Personality Disorders Among Older Adults

Abstract. Four personality disorders (PD) have become “lost” throughout the various editions of the DSM: Depressive, Passive-Aggressive, Sadistic, and Self-Defeating. The Alternative Model of Personality Disorders (AMPD) is a novel approach to PD classification, containing two diagnostic criteria: personality functioning and pathological personality traits. This study identifies the personality functioning and pathological personality trait features of the Lost PDs among older adults ( N = 202; Mage = 67.47 years). Results indicate that the Lost PDs related more strongly with the self-functioning domains (versus the interpersonal domains). Some pathological traits emerged in expected directions, whereas others did not, which is consistent with research on the traditional PDs. The AMPD appears to have mixed validity in capturing the Lost PDs in older adults, though overall it performed comparably well and warrants further examination.

ICD-11 Personality Disorders: Utility and Implications of the New Model.

The ICD-11 classification of personality disorders represents a paradigm shift in diagnosis. This was felt necessary because previous personality disorder classifications had major problems. These included unnecessary complexity, inconsistency with data on normal personality traits, and minimal consideration of severity despite this being shown to be the major predictor of outcome. The ICD-11 classification abolishes all categories of personality disorder except for a general description of personality disorder. This diagnosis can be further specified as “mild,” “moderate,” or “severe.” Patient behavior can be described using one or more of five personality trait domains; negative affectivity, dissociality, anankastia, detachment, and disinhibition. Clinicians may also specify a borderline pattern qualifier. The ICD-11 shows considerable alignment with the DSM-5 Alternative Model for Personality Disorders. Early evidence around the reliability and validity of the new model appear promising, although at present there is still limited specific evidence due to the model being so recently finalized. However, for the model to be successful, it needs to be embraced by clinicians and used widely in normal clinical practice.

The Role of Personality Functioning on Early Drop out in Outpatient Substance Misuse Treatment

Background Treatment initiation is a major factor contributing to positive outcomes, but the supporting literature remains limited. It is difficult to draw conclusions regarding predictors of dropout, and there is a need to target clients’ major early attrition vulnerabilities. Despite empirically validated models for assessing personality, little is known about its role in the treatment process. Studies that have been conducted in this area have focused mainly on stable personality traits and provide conflicting evidence. Aims: The aim of this study is to examine to what extent service users’ personality functioning are potential determinants of early drop out. Methodology: A cross-sectional multi-site design examined the therapy process in a naturalistic setting in 5 outpatient preparation treatment centers with 210 service users. The current study adopts a contemporary dimensional-based framework, similar to the Alternative Model of Personality Disorder of the DSM-V and examines the role of characteristic adaptations (SIPP-118) on early drop out (CEST-Intake). Findings: From the broad spectrum of personality traits, only Depression remained significant predictor of drop out. Higher dysfunctional levels in Social Concordance [OR] = 1.85, Wald =19.87, p =.002, 95% CI [1.1, 1.9] as well as the facets Aggression Regulation, Respect and Purposefulness were also predictors of early drop out, while Treatment Readiness and Desire for Help accounted for a significant amount of variance. Conclusions: These findings extend our knowledge of the predictive role of characteristic adaptations in treatment and suggest it may be important to assess these individual differences early on and to design personalized-informed interventions.

The Utility of ICD-11 and DSM-5 Traits for Differentiating Patients With Personality Disorders From Other Clinical Groups.

The ICD-11 Classification of Personality Disorders delineates five trait domain qualifiers (i.e., negative affectivity, detachment, dissociality, disinhibition, and anankastia), whereas the DSM-5 Alternative Model of Personality Disorders also delineates a separate domain of psychoticism. These six combined traits not only characterize individual stylistic features, but also the severity of their maladaptive expressions. It was, therefore, the aim of this study to investigate the utility of ICD-11 and DSM-5 trait domains to differentiate patients with personality disorders (PD) from patients with other mental disorders (non-PD). The Personality Inventory for DSM-5 Brief Form Plus (PID5BF+M) was administered to a sample of patients diagnosed with a personality disorder (N = 124, Mage = 42.21, 42.7% females) along with a sample of patients diagnosed with other mental disorders (N = 335, Mage = 44.83, 46.6% females). Group differences were explored using the independent sample t test or the Mann–Whitney U test for independent samples, and discriminant factor analysis was used to maximize group differences for each trait domain and facet score. The PD group showed significantly higher scores for the total PID5BF+M composite score, for the trait domains of negative affectivity, antagonism/dissociality, and disinhibition and for the trait facets of emotional lability, manipulativeness, deceitfulness, and impulsivity. The trait domains of disinhibition, negative affectivity, and antagonism/dissociality as well as the trait facets of impulsivity, deceitfulness, emotional lability, and manipulativeness were the best discriminators between PD and non-PD patients. The global PID5BF+M composite score was also one of the best discriminators supporting its potential as a global severity index for detecting personality dysfunction. Finally, high scores in three or more of the 18 PID5BF+M facets suggested the possible presence of a PD diagnosis. Despite some limitations, our findings suggest that the ICD-11 and DSM-5 traits have the potential to specifically describe the stylistic features that characterize individuals with PD, including the severity of their maladaptive expressions.

Semi-structured interview for personality functioning DSM-5 (STiP-5.1): Psychometric evaluation of the Czech version.

The DSM-5 Alternative Model for Personality Disorders introduced a dimensional perspective on personality disorders and their assessment by measuring personality functioning in the following domains: Identity, Self-Direction, Empathy, and Intimacy. This study provides a replication of the psychometric evaluation of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) within a mixed clinical sample and a community sample. The sample consisted of 188 adults: 86 participants from the general population and 102 people from a mixed clinical sample. All participants completed the STiP-5.1 and Level of Personality Functioning Scale-Brief Form (LPFS-BF 2.0). Results showed good internal consistency (McDonald's ω = 0.89-0.94) and promising convergent validity (correlations with LPFS-BF 2.0 above 0.6) of the STiP-5.1. Its scores differentiated participants within the community sample from those in the mixed clinical sample with large effect sizes (rrb = 0.77-0.88). Moreover, the impairment in personality functioning was more pronounced in people with personality disorders than in other psychiatric disorders (medium effect size, rrb = 0.46-0.57), supporting the notion of a continuum of personality functioning impairment. The STiP-5.1 therefore offers an instrument with satisfactory psychometric properties for the assessment of personality functioning both for research and clinical practice.

Stability and Change in Relations Between Personality Traits and the Interpersonal Problems Circumplex During Cognitive Therapy for Recurrent Depression.

Both personality impairment and maladaptive-range traits are necessary for diagnosis in the alternative model of personality disorder. We clarified personality impairment-trait connections using measures of the interpersonal problems circumplex and personality traits among adult outpatients (N = 351) with major depressive disorder receiving cognitive therapy (CT). The trait scales' circumplex projections were summarized by elevation (correlations with general interpersonal problems), amplitude (specific relations to the circumplex dimensions of dominance and affiliation), and angle (predominant orientation in the two-dimensional circumplex). Most trait scales showed hypothesized circumplex relations, including substantive elevation (e.g., negative temperament, mistrust), amplitude (e.g., aggression, detachment), and expected angles (e.g., positive temperament and manipulativeness oriented toward overly nurturant/intrusive or domineering/vindictive problems, respectively), that were stable across time during CT. These results revealed meaningful and consistent impairment-trait connections, even during CT when mean depressive affect decreased substantially.

The ICD-11 Personality Disorder Trait Model Fits the Kurdish Population Better Than the DSM-5 Trait Model.

The ICD-11 Classification of Personality Disorders and the DSM-5 Alternative Model of Personality Disorders (AMPD) operate with trait domains that contribute to the individual expression of personality disturbance (i.e., negative affectivity, detachment, dissociality, disinhibition, anankastia, and psychoticism). To date, these trait frameworks have not been investigated sufficiently in Middle Eastern cultures. Thus, the present study explored the structure of the ICD-11 and AMPD personality disorder (PD) trait domains in a large mixed sample from the Kurdistan zone of Iran. The ICD-11 and AMPD trait domains were operationalized using empirically supported algorithms for the Personality Inventory for DSM-5 (PID-5). The PID-5 was administered to a large mixed sample (N = 3,196) composed of 2,678 community and 518 clinical participants. Structural validity was investigated using Exploratory Factor Analysis (EFA), whereas differential construct validity was explored by comparing clinical and community scores. Model fit and the expected factor structure were deemed appropriate for the ICD-11 trait model, but less adequate for the DSM-5 trait model (i.e., disinhibition did not emerge as a separate factor). All domain and facet scores showed significant differences between clinical and community subsamples with moderate to large effects, mostly for disinhibition and dissociality/antagonism while least for anankastia. The findings of the present study may suggest that the ICD-11 trait model is more cross-culturally fitting than the DSM-5 AMPD trait model, at least with respect to a large mixed sample from the region of Kurdistan. Accordingly, there is evidence for using PID-5 data for WHO ICD-11 purposes in this part of the World.

Assessing Self-Definition and Relatedness in Level of Personality Functioning.

The two polarities model (TPM) of personality organizes psychological assessment and psychotherapy and connects to personality disorder diagnosis using the DSM-5 Alternative Model for Personality Disorders (AMPD). The authors developed scales assessing the TPM from an existing self-report measure for level of personality functioning (LPF), a core component of the AMPD. Iterative content analyses of the LPF measure yielded scales for Autonomy and Communion corresponding to dimensions of the TPM. The scales were refined via internal consistency analyses using a measure of psychological attachment and studied in development and validation samples. Associations with relevant external criteria were explored in a series of multiple regressions. The new content-based LPF scales were illustrated with a case vignette. Although the new Autonomy/Communion scales await further validation prior to clinical use, initial evidence suggests that they may bridge the nomological nets of the TPM and AMPD and potentially offer clinical utility in assessment and treatment planning.

Interpersonal Problems in Parents and Adolescent Borderline Personality Disorder Features.

Research shows that parental personality pathology is associated with borderline personality disorder features and internalizing/externalizing symptoms in offspring. However, studies have been limited by DSM-IV-based assessments of parental personality pathology. The authors leveraged evidence that interpersonal problems described by the Interpersonal Circumplex align with Criterion A of the DSM-5 Alternative Model for Personality Disorders and therefore used a measure of interpersonal problems to capture parental personality pathology. The authors hypothesized that parental interpersonal problems would be associated with a latent variable of borderline features in adolescent offspring. They also examined whether this relation with offspring borderline features existed above and beyond relations with offspring internalizing/externalizing symptoms, age, and gender. The sample included 524 inpatient adolescents (Mage = 15.31, 62.4% female) and their parents (80.5% female). Parental interpersonal problems demonstrated unique relationships with adolescent borderline features and externalizing symptoms, but not internalizing symptoms. Implications of the results, limitations, and future directions are discussed.

A Proposed Classification of ICD-11 Severity Degrees of Personality Pathology Using the Self and Interpersonal Functioning Scale.

Background: The 11th version of the World Health Organization's International Classification of Diseases (ICD-11) has adopted a dimensional approach to personality disorder (PD) nosology. Notably, it includes an assessment of PD degree of severity, which can be classified according to five categories. To date, there is no gold standard measure for assessing degree of PD severity based on the ICD-11 model, and there are no empirically-based anchor points to delineate the proposed categories. With the operationalization of PD degrees of severity in the ICD-11 PD model now being closely aligned with Criterion A of the DSM-5 Alternative Model for Personality Disorders (AMPD), sharing a focus on self and interpersonal dysfunction, self-report instruments developed for the latter model might prove useful as screening tools to determine degrees of severity in the former.Methods: The Self and Interpersonal Functioning Scale, a brief validated self-report questionnaire originally designed to assess level of personality pathology according to the AMPD framework, was used to derive anchor points to delineate the five severity degrees from the ICD-11 PD model. Data from five clinical and non-clinical samples (total N = 2,240) allowed identifying anchor points for classification, based on Receiver Operating Characteristic curve analysis, Latent Class Analysis, and data distribution statistics. Categories were validated using multiple indices pertaining to externalizing and internalizing symptoms relevant to PD.Results: Analyses yielded the following anchor points for PD degrees of severity: No PD = 0–1.04; Personality Difficulty = 1.05–1.29; Mild PD = 1.30–1.89; Moderate PD = 1.90–2.49; and Severe PD = 2.50 and above. A clear gradient of severity across the five categories was observed in all samples. A high number of significant contrasts among PD categories were also observed on external variables, consistent with the ICD-11 PD degree of severity operationalization.Conclusions: The present study provides potentially useful guidelines to determine severity of personality pathology based on the ICD-11 model. The use of a brief self-report questionnaire as a screening tool for assessing PD degrees of severity should be seen as a time-efficient support for clinical decision and treatment planning.

The Self-Concept and Identity Measure in Adolescents

Abstract. Identity difficulties have been associated with various psychiatric conditions and are considered a central issue in personality pathology. Following the Alternative Model for Personality Disorders, measures of self- and interpersonal functioning have been developed. Although these measures were intended to be separate ratings of self-other deficits, only a global rating was obtained. Moreover, these measures fall short in bridging the gap between developmental and clinical identity work. To capture both adaptive and disturbed identity dimensions, Kaufman et al. (2015) developed the Self-Concept and Identity Measure (SCIM) that assesses consolidated identity, disturbed identity, and lack of identity. Using two-wave longitudinal data (2,150 adolescents; 54.2% girls; age range = 12–19), this study investigated the factor structure and reliability of the Dutch SCIM, its measurement invariance across time, its longitudinal measurement invariance across gender and age groups, and associations of the SCIM with identity synthesis and confusion, Big-Five personality traits, and borderline personality disorder features. Consolidated identity scores were positively related to identity synthesis and adaptive Big-Five traits, whereas negatively related to identity confusion, neuroticism, and borderline features. Opposite associations were obtained for disturbed identity and lack of identity scores. The Dutch SCIM appeared to produce valid and reliable scores and seemed suited to assess longitudinal identity functioning in Belgian adolescents.

The longitudinal impact of DSM–5 Section III specific personality disorders on relationship satisfaction.

Maladaptive personality features, in the form of dimensional traits or symptoms of personality disorders, have been linked with lower levels of relationship satisfaction. Most of this research, however, has been cross-sectional, and little is known about the effect of specific personality disorder types, as measured dimensionally, on relationship satisfaction. In the current study, we used actor partner interdependence modeling (APIM) with self-reported personality traits from the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and spouse-reported traits from the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Informant Report Form. Composite scores for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Section III Specific Personality Disorder Types, based on combinations of PID facets as outlined in the Section III criteria, were used to predict relationship satisfaction 1 year after personality was assessed. The alternative model of personality disorders composites significantly predicted relationship satisfaction both cross-sectionally and longitudinally. Results indicated that spouse reports of personality disorder types from the alternative model of personality disorders framework were robust predictors of satisfaction. Thus, individuals who perceive their partners as high in personality pathology (at any point in a relationship) are likely to be subsequently dissatisfied in the relationship. Interventions targeting perceptions of one's partner might be an effective way to improve marital satisfaction for these individuals. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Temperaments and characters: incompatible or complementary components for criterion B of the alternative model in predicting DSM-5 section II personality disorders?

Many studies have found clear correspondence among the domains of the five-factor model of personality (FFM) and the alternative model of personality disorders (AMPD) in DSM-5-III, which is assessed with the Personality Inventory for DSM-5 (PID-5). However, very few studies have compared the PID-5 with the other well-known established dimensional models of personality such as Cloninger's model. The present study examined whether the Temperament and Character Inventory (TCI-125) dimensions, PID-5 dimensions, or a combination would represent PD-scale scores more accurately. In this regard, 437 college students completed the Persian version of the PID-5, TCI-125 and SCID-II Screening Questionnaire.RESULTS The results indicated that cooperativeness (low), self-directedness (low), and self-transcendence (high) characters of the TCI-125 and the psychoticism (high) domain of the PID-5 are the most consistent predictors of all PD-scale scores. Overall, the findings showed that an integrative model, combining dimensions of the TCI-125 and PID-5, represented the features of PD-scale scores most effectively.

Psychometric Properties of the Personality Inventory for DSM-5 in a Romanian Community Sample

The Personality Inventory for DSM-5 (PID-5) evaluates 25 maladaptive personality traits proposed in the Alternative Model of Personality Disorders. The questionnaire has been extensively investigated and validated in several languages. The current research sought to examine the psychometric properties of the instrument in a sample of nonclinical Romanian participants (N = 1276). Results indicated excellent internal consistency for the domain level, and very good reliability for the facet level. The assumption of unidimensionality was supported at both the domain and facet levels, apart from Risk Taking. Two domain scoring methods were also compared. One of them takes into consideration all the 25 lower order facets, whereas the other uses only 15 facets. Results show that mean differences across the two scoring methods were small, except for Disinhibition. Moreover, confirmatory factor analyses revealed slightly better fit indices for the model which uses 15 facets only. Lastly, the hierarchical structure of maladaptive personality traits was explored. Results are discussed in the light of previous literature.

Psychopathy and the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition alternative model of personality disorder: a synthesis and critique of the emergent literature.

Including the psychopathic specifier within the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition alternative model of personality disorder (AMPD) trait conceptualization of antisocial personality disorder (ASPD) represents a significant development in the history of the conceptualization of ASPD and its relationship to psychopathy. This review presents a synthesis and critique of emerging literature pertaining to AMPD ASPD and the psychopathic specifier. The current review draws attention to the utility of ASPD impairment ratings and traits to effectively measure psychopathy, shortcomings of the psychopathic specifier, research efforts to improve upon the conceptualization of AMPD psychopathy, and ASPD and psychopathic specifier trait complexity. AMPD domains and ASPD designated traits converge with interpersonal, antagonistic, and disinhibitory domains of psychopathy but demonstrate poorer convergence with boldness/fearless dominance. The separate assessment of ASPD impairment adds little to the prediction of psychopathy beyond ASPD trait severity. Although the psychopathic specifier maps onto boldness/fearless dominance domains of psychopathy, theoretical and empirical limitations hinder the utility of the psychopathic specifier and reconceptualization will likely be required. Finally, complex ASPD and psychopathic specifier facet interrelationships and diverse relationships with externalizing outcomes suggests the development of advanced interpretive guides for clinical practice should be a high priority.

Differences between ICD-11 PTSD and complex PTSD on DSM-5 section III personality traits

ABSTRACT Background: The formulations of post-traumatic stress disorder (PTSD) and the newly included disorder complex PTSD (CPTSD) in the 11th edition of the International Classification of Diseases (ICD-11) have not been evaluated on a broad range of maladaptive personality traits. Objective: The aim of this study was to evaluate ICD-11 PTSD and CPTSD on maladaptive personality traits. Method: In a cross-sectional study of 106 Danish outpatients with ICD-10 PTSD, we used the International Trauma Questionnaire (ITQ) to identify patients with either ICD-11 PTSD or CPTSD (N = 84). We utilized the Personality Inventory for DSM-5 (PID-5) from the alternative model of personality disorders in DSM-5, section III, to evaluate personality trait differences between ICD-11 PTSD and CPTSD. Furthermore, PID-5 was also used to investigate relationships between personality traits and ICD-11 PTSD/CPTSD symptom clusters. The Life Event Checklist was used to assess traumatic experiences, and the MINI International Neuropsychiatric Interview was applied to assess comorbidity. Results: Patients with ICD-11 PTSD or CPTSD had elevated scores on personality traits indicative of internalizing psychopathology. However, higher impairment levels of the trait domains Negative Affectivity (d= 0.75) and Psychoticism (d = 0.80) discriminated patients with ICD-11 CPTSD from patients with PTSD. The PID-5 trait domain Detachment was moderately positively correlated to most of the ITQ symptom clusters and, the ITQ Negative Self-concept symptom cluster showed a relatively high number of significant correlations across all the PID-5 trait domains and facets. The PID-5 domain Negative Affectivity and almost all the encompassing facets were significantly correlated with DSO symptom clusters. Conclusions: The findings demonstrate the relevance of applying dimensional assessment of personality features to study the psychopathology of ICD-11 PTSD and CPTSD and potential differences. The results suggest that CPTSD is a more debilitating disorder than PTSD considering the severity of the personality features.

DSM-5 alternative personality disorder model traits as extreme variants of five-factor model traits in adolescents.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) recognizes a developmental perspective on personality pathology owing to its proposal to conceptualize personality pathology in terms of maladaptive personality traits. Previous research has found that the DSM-5 maladaptive traits and the five-factor model (FFM) for normative personality traits share common underlying dimensions. Although the DSM-5 generally assumes DSM-5 traits to be extreme versions of FFM traits, empirical evidence is scarce in adolescents. The present study therefore extended previous studies by comparing the Personality Inventory for DSM-5 and the Big Five Inventory-2 (BFI-2) in an adolescent sample (n = 353), using item response theory. Results indicated an underlying dimension for all domain pairs except for FFM Openness and Psychoticism. Consistent with the general assumption, IRT results demonstrated that Personality Inventory for DSM-5 scales generally provided more information than the BFI-2 scales at the upper levels of the latent dimension. The BFI-2 scales provided more information at the lower levels. For FFM Conscientiousness and Disinhibition, however, the BFI-2 scale provided more information for almost the entire range of the latent dimension. The findings indicate similarities in the DSM-5 conceptualization of personality pathology between adults and adolescents and at the same time identify important differences that need to be considered.
