DSM-5 Level of Personality Functioning: Refocusing Personality Disorder on What It Means to Be Human

Unravelling the Longitudinal Relations Between Developmental Milestones, General Psychopathology, and Personality Functioning in a Youth Clinical Sample

Personality functioning, general psychopathology, and developmental milestones achievement are critical domains in the field of young people's mental health; however, no prior research has considered these variables jointly or examined the temporal dynamics between them. To fill these gaps, the present study aimed to investigate the longitudinal associations between the above constructs in a clinical sample of Dutch youth. 525 outpatients (72.5% women; age range: 12-26 years, M = 18.8 ± 2.83) diagnosed with different psychological difficulties were recruited from specialized mental health care services in The Netherlands. They completed self-report measures assessing personality functioning, psychopathological symptoms, and the achievement of youth-specific developmental milestones. Data were collected on three occasions within a year and modelled using a Cross-Lagged Panel Model approach. The levels of personality dysfunction, general psychopathology, and developmental milestones achievement were found to fluctuate from one wave to the other. Personality dysfunction and general psychopathology were positively interrelated at each time point, while both constructs were negatively associated with developmental milestones achievement. Importantly, difficulties achieving developmental milestones predicted a worsening in personality functioning 6 months later. This result would suggest that the achievement of developmental milestones precedes personality functioning, supporting the importance of interventions promoting age-adequate functioning in youth.

Socially isolated, but not lonely in lockdown: Exploring the role of reflective functioning as a protective factor in the early days of the COVID-19 pandemic in Germany

INTRODUCTION

Loneliness is a pressing public mental health issue. So far, there has been a paucity of investigations focused on the individual differences modulating this subjective feeling in the face of difficult circumstances, e.g., the COVID-19 pandemic. As such, the present study aimed to investigate the role of mentalization; given that the construct comprises reflection abilities that might be particularly relevant to the pandemic's interpersonal challenges.

METHODS

A survey representative of the German population was conducted from May to June 2020 (N = 2503). We examined mentalization, operationalized as reflective functioning (RF) and measured using the Mentalization Questionnaire (MZQ), both as a protective factor against loneliness on its own and as a moderator of the association of social isolation with loneliness.

RESULTS

Of the overall sample, 822 (32.8 %) individuals reported social isolation. Worse RF was moderately associated with higher levels of loneliness (r = 0.433, p < .001). A linear regression model (controlling for sociodemographic characteristics and general personality pathology) confirmed this positive association, but also indicated an interaction effect of RF and social isolation in the statistical prediction of loneliness. Stratified models showed that RF was a comparatively weaker statistical predictor of loneliness among the socially isolated.

DISCUSSION

This representative population study expanded our knowledge about the factors shaping loneliness in the population. RF emerged as a potentially modifiable protective influence. Further research needs to clarify the mechanisms through which it mitigates loneliness.

LIMITATIONS

The cross-sectional design does not give insight into the temporal association of RF and loneliness.

First Psychometric Evaluation of the English Version of the Semi-Structured Interview for Personality Functioning (STiP-5.1)

The Alternative Model for Personality Disorders provides a dimensional framework for the conceptualization of personality disorders where Criterion A concerns the assessment of one's level of personality functioning (LPF). This study examines the psychometric properties of the English translation of the Semi-Structured Interview for Personality Functioning (STiP-5.1) to validate this translation for the assessment of LPF in English-speaking populations; and examine whether this measure increments self-report measures of LPF and personality pathology in predicting general functioning. The sample consisted of 129 emerging adults between 18 and 25 years of age (M = 20.54, SD = 2.08) from a mixed college and clinical sample. Results support a unidimensional factor structure of the STiP-5.1, good internal consistency, and high inter-rater reliability. Construct validity was supported through associations of the STiP-5.1 with self-report measures of LPF and personality pathology. The STiP-5.1 incremented self-report measures of personality pathology in predicting functional impairment, though additional variance explained was modest. Finally, STiP-5.1 scores differentiated individuals who obtained a score at or above the clinical cutoff from those below on self-report measures of personality pathology and LPF with large effect sizes. Findings support the validity of the English translation of the STiP-5.1 for the assessment of LPF.

Maladaptive personality traits are associated with burnout risk in Italian anesthesiologists and intensivists: a secondary analysis from a cross-sectional study

BACKGROUND

Burnout is a maladaptive response to chronic stress, particularly prevalent among clinicians. Anesthesiologists are at risk of burnout, but the role of maladaptive traits in their vulnerability to burnout remains understudied.

METHODS

A secondary analysis was performed on data from the Italian Association of Hospital Anesthesiologists, Pain Medicine Specialists, Critical Care, and Emergency (AAROI-EMAC) physicians. The survey included demographic data, burnout assessment using the Maslach Burnout Inventory (MBI) and subscales (emotional exhaustion, MBI-EE; depersonalization, MBI-DP; personal accomplishment, MBI-PA), and evaluation of personality disorders (PDs) based on DSM-IV (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition) criteria using the assessment of DSM-IV PDs (ADP-IV). We investigated the aggregated scores of maladaptive personality traits as predictor variables of burnout. Subsequently, the components of personality traits were individually assessed.

RESULTS

Out of 310 respondents, 300 (96.77%) provided complete information. The maladaptive personality traits global score was associated with the MBI-EE and MBI-DP components. There was a significant negative correlation with the MBI-PA component. Significant positive correlations were found between the MBI-EE subscale and the paranoid (r = 0.42), borderline (r = 0.39), and dependent (r = 0.39) maladaptive personality traits. MBI-DP was significantly associated with the passive-aggressive (r = 0.35), borderline (r = 0.33), and avoidant (r = 0.32) traits. Moreover, MBI-PA was negatively associated with dependent (r =  - 0.26) and avoidant (r =  - 0.25) maladaptive personality features.

CONCLUSIONS

There is a significant association between different maladaptive personality traits and the risk of experiencing burnout among anesthesiologists. This underscores the importance of understanding and addressing personality traits in healthcare professionals to promote their well-being and prevent this serious emotional, mental, and physical exhaustion state.

Competing Models of Personality Disorder: Relations With Psychosocial Functioning

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013), includes 10 categorical personality disorders (PD) in Section II (Section II PD) and a dimensional alternative model of PD (AMPD) in Section III. We compared the two models in explaining concurrent psychosocial functioning levels in psychiatric outpatients and community residents screened as at risk for PD pathology (N = 600). The AMPD's fully dimensional form showed stronger associations with psychosocial difficulties and explained more of their variance compared with the categorical Section II PD. AMPD Criterion A (personality functioning impairment) and Criterion B (pathological traits) incrementally predicted psychosocial functioning about equally with some unique predictions. Finally, AMPD's six categorical PD diagnoses did not show stronger associations with psychosocial functioning than the corresponding Section II PD diagnoses. Findings directly comparing the two models remain important and timely for informing future conceptualizations of PD in the diagnostic system.

The sensitivity of the ICD-11 trait model to the symptoms of clinical disorders in young adults

Hierarchical psychopathology contributes to providing a broader picture of the links between emerging personality structures such as the DSM-5/ICD-11 trait models and clinical disorders. The present study aimed to predict the specific and general clinical symptoms by the less studied constructs of the ICD-11 model (negative affectivity, detachment, dissociality, disinhibition, and anankastia). Data from 642 young adults from Iran (63% female, 18-34 years) were collected by three mental symptom scales and the Personality Inventory for DSM-5 (PID-5), which was recently used to harmonize the constructs of the DSM-5 and ICD-11 trait models. Multiple linear regressions showed that the ICD-11 model significantly predicted both the specific clinical symptoms (ranging from R2 = 0.15 to 0.40) and the general factor of clinical symptoms extracted by exploratory factor analysis (R2 = 0.40, all p < 0.001). Negative affectivity was the strongest construct correlated with both the specific symptoms (ranging from β = 0.36 to 0.69) and the general symptom factor (β = 0.59, all p < 0.001). Because the ICD-11 trait model is a practical structure related to the clinical psychopathology in young adults, screening for maladaptive traits can help clinicians in case formulation for diagnosis and treatment.

Personality Functioning, Problems in Living, and Personality Traits

The publication of the Alternative Model of Personality Disorder (AMPD) was a signpost achievement in the personality assessment. However, research on the AMPD has generally not led to either a deeper understanding of personality disorder or personality assessment or new ideas about how to provide better care for people with personality disorder diagnoses. A significant portion of research has focused on narrow issues and appears to be driven in part by ideological differences between scholars who prefer Criterion A (personality functioning) or Criterion B (maladaptive traits). I trace these issues to ambiguity about the concept of personality functioning as defined in the AMPD and its conceptual distinction from personality traits and problems in living. In this paper, I reground these concepts in coherent and distinct definitions, elaborate upon the implications of their differences, and show how these differences can help clarify and reorient AMPD research to focus on generating clinically useful models for personality pathology and personality assessment.

Awareness of Narrative Identity Questionnaire (ANIQ) in Early Adolescents: Psychometric Evaluation and Association with Features of Personality Disorder

Identity formation is central to adolescent development. Challenges in establishing a stable sense of self is associated with maladaptive identity function, which has been recognized as a core feature of personality pathology. The narrative identity framework offers a unique lens to garner salient information about one's sense of self. The Awareness of Narrative Identity Questionnaire (ANIQ) is a self-report measure of narrative identity validated in adults but is yet to be validated in adolescents. The current study aimed to conduct the first psychometric evaluation of the ANIQ in a sample of 205 youth aged 10-14 years (M = 12.1 ± 1.06 years; 50.7% female; 73.7% Hispanic) recruited from a public charter school. Results confirmed the four-factor structure of the ANIQ and showed high internal consistency. Convergent validity was supported through negative associations between the ANIQ and borderline personality features and identity diffusion. Incremental validity of the ANIQ over identity diffusion in predicting borderline personality features was also examined, but not supported. Overall, results support the ANIQ as a promising instrument for the assessment of narrative identity in youth. However, some improvements to the ANIQ might be necessary in order to use it as a clinical tool in identifying youth with personality pathology.

Clinical profiles of adolescent personality pathology: a latent structure examination of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) in a help-seeking sample

BACKGROUND

Despite the introduction of dimensional conceptualisations of personality functioning in the latest classification systems, such as Criterion A of the Alternative Model of Personality Disorders in the DSM-5, heterogeneous clinical presentation of personality pathology remains a challenge. Relatedly, the latent structure of personality pathology as assessed by the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) has not yet been comprehensively examined in adolescents. Therefore, this study aimed to examine the latent structure of the STiP-5.1, and, based on those findings, to describe any unique clinical profiles that might emerge.

METHODS

The final sample comprised 502 participants aged 11-18 years consecutively recruited from a specialised personality disorder outpatient service, as well as general day clinic and inpatient wards at the University Hospital University Hospital of Child and Adolescent Psychiatry and Psychotherapy, University Hospital Bern, Switzerland. Participants were assessed using the STiP-5.1, as well as a battery of other psychological measures by clinical psychologists or trained doctoral students. Variations of Factor Analysis, Latent Class Analysis and Factor Mixture Models (FMM) were applied to the STiP-5.1 to determine the most appropriate structure.

RESULTS

The best fitting model was an FMM comprising four-classes and two factors (corresponding to self- and interpersonal-functioning). The classes differed in both overall severity of personality functioning impairment, and in their scores and clinical relevance on each element of the STiP-5.1. When compared to the overall sample, classes differed in their unique clinical presentation: class 1 had low impairment, class 2 had impairments primarily in self-functioning with high depressivity, class 3 had mixed levels of impairment with emerging problems in identity and empathy, and class 4 had severe overall personality functioning impairment.

CONCLUSIONS

A complex model incorporating both dimensional and categorical components most adequately describes the latent structure of the STiP-5.1 in our adolescent sample. We conclude that Criterion A provides clinically useful information beyond severity (as a dimensional continuum) alone, and that the hybrid model found for personality functioning in our sample warrants further attention. Findings can help to parse out clinical heterogeneity in personality pathology in adolescents, and help to inform early identification and intervention efforts.

Social and Monetary Reward Processing in Youth with Early Emerging Personality Pathology: An RDoC-Informed Study

Very little is known about the mechanisms underlying the development of personality disorders, hindering efforts to address early risk for these costly and stigmatized disorders. In this study, we examined associations between social and monetary reward processing, measured at the neurophysiological level, and personality pathology, operationalized through the Level of Personality Functioning (LPF), in a sample of early adolescent females (Mage = 12.21 years old, SD = 1.21). Female youth with (n = 80) and without (n = 30) a mental health history completed laboratory tasks assessing social and monetary reward responsiveness using electroencephalogram (EEG) and completed ratings of personality pathology. Commonly co-occurring psychopathology, including depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) were also assessed. At the bivariate level, significant associations did not emerge between psychopathology and reward processing variables. When covarying symptoms of depression, anxiety, ADHD, ODD, and CD, an enhanced reward positivity (RewP) component to social reward feedback (accounting for response to social rejection) was associated with higher levels of personality impairment. Results were specific to social rather than monetary reward processing. Depression, anxiety, and ODD also explained unique variance in LPF. These findings suggest that alterations in social reward processing may be a key marker for early emerging personality pathology. Future work examining the role of social reward processing on the development of LPF across adolescence may guide efforts to prevent the profound social dysfunction associated with personality pathology.

Assessing Criterion A of the Alternative Model for Personality Disorders: The Potential of Performance-Based Personality Measures

The conceptualization of personality disorder has been refined through recent nosological advances introduced in the Alternative Model for Personality Disorders (AMPD). These advances locate self and interpersonal (dys)function at the core of personality pathology. Self-report personality assessment instruments have demonstrated promise in the assessment of Criterion A domains. However, research highlighting the utility of performance-based personality assessment instruments has been largely absent in these advances, despite acknowledgment of their potential. We adhered to PRISMA review guidelines to survey and assess the potential relevance and utility of select performance-based personality instruments in assessing Criterion A domains of the AMPD. We conclude that performance-based personality measures are uniquely positioned to assess maladaptive self- and interpersonal functioning and may address some limitations of self-report measures. Toward this end, we propose a working model that provides ranges of test scores that correspond to the 5-point scale of the Criterion A domains of the AMPD.

The Dimensional Conceptualization of Personality Disorders: Personality Organization, Personality Functioning, and Personality Disorders

Over the past several decades, significant criticism of the categorical classification system for personality disorders has highlighted the need to transition to a dimensional classification system. This study reviewed key issues involved in the potential conversion of the diagnostic system of personality disorders from a categorical to a dimensional model. The result suggests that Kernberg's concept of personality organization can be used to indicate the overall severity of personality pathology.

Patient personality and therapist responses in the psychotherapy of adolescents with depressive disorders: toward the Psychodynamic Diagnostic Manual - third edition

Depressive disorders in adolescence pose unique challenges for assessment and treatment, particularly due to their high comorbidity with various personality disorders. Moreover, young depressed patients may elicit very intense and difficult-to-manage emotional responses in therapists (in this context, countertransference). This study aimed at empirically identifying specific personality disorders (or subtypes) among adolescents with depressive pathology and exploring distinct countertransference patterns emerging in their psychotherapy: 100 adolescents (58 with depressive disorders; 42 with other clinical conditions) were assessed by their respective clinicians (n=100) using the psychodiagnostic chart-adolescent of the Psychodynamic Diagnostic Manual (PDM) - second edition, and the therapist response questionnaire for adolescents. Results showed that depressed adolescent patients exhibited marked traits of four personality subtypes (i.e., depressive, anxious-avoidant, narcissistic, and borderline) characterized by different levels of mental functioning and personality organization. These subtypes were predictably related to specific clinicians' emotional responses, even when controlling for the intensity of depressive symptomatology. Patients with depressive or anxious-avoidant personality subtypes evoked more positive countertransference responses, whereas patients with narcissistic or borderline subtypes elicited strong and hard-to-face emotional responses in therapists. Consistent with the next edition of the PDM, the study emphasizes the importance of comprehensive psychodynamic assessment in the developmental age, which frames depressive disorders in the context of accurate emerging personality and mental functioning profiles. This approach, which also relies heavily on the clinician's subjective experience in therapy, provides crucial information on how to specifically tailor interventions that more effectively meet the needs of adolescents with these heterogeneous and complex clinical conditions.

Personality disorder coverage, prevalence, and convergence: do the DSM-5's two models of personality disorder identify the same patients?

BACKGROUND

Research on the Alternative DSM-5 Model for Personality Disorders (AMPD) in DSM-5's Section-III has demonstrated acceptable interrater reliability, a largely consistent latent structure, substantial correlations with theoretically and clinically relevant measures, and evidence for incremental concurrent and predictive validity after controlling for DSM-5's Section II categorical personality disorders (PDs). However, the AMPD is not yet widely used clinically. One clinician concern may be caseness - that the new model will diagnose a different set of PD patients from that with which they are familiar. The primary aim of this study is to determine whether this concern is valid, by testing how well the two models converge in terms of prevalence and coverage.

METHOD

Participants were 305 psychiatric outpatients and 302 community residents not currently in mental-health treatment who scored above threshold on the Iowa Personality Disorder Screen (Langbehn et al., ). Participants were administered a semi-structured interview for DSM-5 PD, which was scored for both Section II and III PDs.

RESULTS

Convergence across the two PD models was variable for specific PDs, Good when specific PDs were aggregated, and Very Good for 'any PD.'

CONCLUSIONS

Results provide strong evidence that the AMPD yields the same overall prevalence of PD as the current model and, further, identifies largely the same overall population. It also addresses well-known problems of the current model, is more consistent with the ICD-11 PD model, and provides more complete, individualized characterizations of persons with PD, thereby offering multiple reasons for its implementation in clinical settings.

A Longitudinal Network of Borderline-Related Trait Vulnerabilities from Childhood to Adolescence

Early maladaptive traits are predictive of later borderline personality pathology (BPP), but little is known about their dynamic interplay over time. This is an important issue to address, however, as significant differences in the 'clinical weight' of various traits constituting the early BPP trait phenotype may inform the field on important target constructs from an early intervention perspective. Therefore, the current study aims to uncover the complex dependencies between BPP traits across the crucial developmental period of childhood and adolescence, by using longitudinal network analysis. Both between- and within-person networks were constructed to identify how early mother-reported borderline-related traits are connected across a timespan of six years (ntime 1 = 718, Mtime1 = 10.73 years, SDtime1 = 1.39, 55.1% girls). Overall, the temporal network suggested various trait interdependencies, with internalizing traits being particularly influential in the development of the BPP trait network structure. At the same time, externalizing traits likely inhibit the negative effects of these core traits. In addition, results also revealed that internalizing and externalizing clusters of early borderline-related traits are linked through emotional lability. Implications of these findings are discussed in view of the change mechanisms at play and potential targets for early intervention.

Taking stock to move forward: Where the field of developmental psychopathology might be heading

In this paper, dedicated to Dante Cicchetti's contributions and enduring influence, we explore the prospective directions of developmental psychopathology. Our focus centers on key domains where Cicchetti's significant achievements have continually shaped our evolving thinking about psychological development. These domains include (a) the concepts of equifinality and multifinality, along with the challenges in predicting developmental trajectories, (b) the imperative to integrate wider sociocultural viewpoints into developmental psychopathology frameworks, (c) the interplay of genetic and environmental influences in developmental courses, (d) the significance of mental state language, and (e) the progress, or its absence, in the development of prevention and intervention tactics for children, adolescents, and their caregivers. While many of our forecasts regarding the future of developmental psychopathology may not materialize, we maintain optimistic that the essential ideas presented will influence the research agenda in this field and contribute to its growth over the next fifty years.

Unresolved attachment and identity diffusion in adolescence

This study examined the severity of unresolved attachment underlying adolescent identity diffusion. Our sample consisted of 180 inpatient adolescents aged 14 to 18 years (77% female, M age = 15.13, SD = 1.35; 23% male, M age = 14.85, SD = 1.41) and 84 age-matched non-clinical adolescents (52% female, M age = 16.14, SD = 1.21; 48% males, M age = 15.98, SD = 1.07). We used the Adult Attachment Projective Picture System (AAP) interview to assess attachment representations and the Assessment of Identity Development in Adolescence (AIDA) questionnaire to evaluate the severity of identity diffusion. Our results demonstrate a higher amount of unresolved attachment and identity diffusion in the patient sample than in the control sample. Furthermore, patients with an unresolved attachment status scored higher on identity diffusion than those with no unresolved attachment pattern. Interestingly, this was not found in the control group. Furthermore, patients with a greater severity of unresolved attachment showed the highest maladaptive identity development scores. Psychotherapeutic interventions integrating attachment-related aspects might be useful to treat young people with identity diffusion.

Borderline personality disorder: a comprehensive review of diagnosis and clinical presentation, etiology, treatment, and current controversies

Borderline personality disorder (BPD) was introduced in the DSM-III in 1980. From the DSM-III to the DSM-5, no major changes have occurred in its defining criteria. The disorder is characterized by instability of self-image, interpersonal relationships and affects. Further symptoms include impulsivity, intense anger, feelings of emptiness, strong abandonment fears, suicidal or self-mutilation behavior, and transient stress-related paranoid ideation or severe dissociative symptoms. There is evidence that BPD can be reliably diagnosed and differentiated from other mental disorders by semi-structured interviews. The disorder is associated with considerable functional impairment, intensive treatment utilization, and high societal costs. The risk of self-mutilation and suicide is high. In the general adult population, the lifetime prevalence of BPD has been reported to be from 0.7 to 2.7%, while its prevalence is about 12% in outpatient and 22% in inpatient psychiatric services. BPD is significantly associated with other mental disorders, including depressive disorders, substance use disorders, post-traumatic stress disorder, attention-deficit/hyperactivity disorder, bipolar disorder, bulimia nervosa, and other personality disorders. There is convincing evidence to suggest that the interaction between genetic factors and adverse childhood experiences plays a central role in the etiology of BPD. In spite of considerable research, the neurobiological underpinnings of the disorder remain to be clarified. Psychotherapy is the treatment of choice for BPD. Various approaches have been empirically supported in randomized controlled trials, including dialectical behavior therapy, mentalization-based therapy, transference-focused therapy, and schema therapy. No approach has proved to be superior to others. Compared to treatment as usual, psychotherapy has proved to be more efficacious, with effect sizes between 0.50 and 0.65 with regard to core BPD symptom severity. However, almost half of the patients do not respond sufficiently to psychotherapy, and further research in this area is warranted. It is not clear whether some patients may benefit more from one psychotherapeutic approach than from others. No evidence is available consistently showing that any psychoactive medication is efficacious for the core features of BPD. For discrete and severe comorbid anxiety or depressive symptoms or psychotic-like features, pharmacotherapy may be useful. Early diagnosis and treatment of BPD can reduce individual suffering and societal costs. However, more high-quality studies are required, in both adolescents and adults. This review provides a comprehensive update of the BPD diagnosis and clinical characterization, risk factors, neurobiology, cognition, and management. It also discusses the current controversies concerning the disorder, and highlights the areas in which further research is needed.

Differentiation of Self and Interpersonal Functioning with the Level of Personality Functioning Scale - Brief Form 2.0

Research on Criterion A of the alternative model for personality disorders is recently expanding and provides mixed results concerning the unidimensional operational definition of severity by the model, characterized by impaired self (identity and self-direction) and interpersonal (empathy and intimacy) functioning. Studies resulted in one, as well as two or more factor structures. The present study demonstrated the importance of the structural and relational differentiation of self and interpersonal dimensions of personality functioning. One thousand seventy-four participants (community and clinical mixed sample) completed the Level of Personality Functioning Scale - Brief Form 2.0 (LPFS-BF 2.0), the Personality Inventory for DSM-5 Short Form and the Questionnaire for the World Health Organization Disability Assessment. An LPFS-BF 2.0 two-factor structure with self and interpersonal functioning factors was corroborated by confirmatory factor analyses and bifactor modeling. Joint Exploratory Factor Analysis of the LPFS-BF 2.0 domains with maladaptive personality domains clearly differentiated the personality functioning factors. While the self-functioning factor was more closely linked to negative affect (and to disinhibition and psychoticism), the interpersonal functioning factor connected to detachment. Self-functioning predicted functional impairment along and beyond personality domains. The LPFS-BF 2.0 appears a useful tool for clinical routine monitoring of both self and interpersonal functioning.

Evidence-Based Assessment of Personality Disorder

The purpose of this article is to provide a description and discussion of the evidence-based assessment of personality disorder. Considered herein is the assessment of the Section II personality disorders included within the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (5th ed., text rev.; DSM-5-TR), within Section III of DSM-5-TR, and within the 11th edition of the World Health Organization's International Classification of Diseases (WHO). The recommendation for an evidence-based assessment is for a multimethod approach: first administer a self-report inventory to alert the clinician to maladaptive personality functioning that might not have otherwise been anticipated, followed by a semi-structured interview to verify the personality disorder's presence. The validity of this multimethod strategy can be improved further by considering the impact of other disorders on the assessment, documenting temporal stability, and establishing a compelling, empirical basis for cutoff points.

Evaluating the Psychometric Properties of the German Self and Interpersonal Functioning Scale (SIFS)

The Self and Interpersonal Functioning Scale (SIFS) is a 24-item self-report questionnaire assessing personality functioning according to the alternative DSM-5 model for personality disorders. We evaluated the German SIFS version in a total sample of 886 participants from Germany and Switzerland. Its factor structure was investigated with confirmatory factor analysis comparing bifactor models with two specific factors (self- and interpersonal functioning) and four specific factors (identity, self-direction, empathy, and intimacy). The SIFS sum and domain scores were tested for reliability and convergent validity with self-report questionnaires and interviews for personality functioning, -organization, -traits, -disorder categories, and well-being. None of the bifactor models yielded good model fit, even after excluding two items with low factor loadings and including a method factor for reverse-keyed items. Based on a shortened 22-item SIFS version, models suggested that the g-factor explained 52.9-59.6% of the common variance and that the SIFS sum score measured the g-factor with a reliability of .68-.81. Even though the SIFS sum score showed large test-retest reliability and correlated strongly with well-established self-report questionnaires and interviews, the lack of structural validity appears to be a serious disadvantage of the SIFS compared to existing self-reports questionnaires of personality functioning.

Loneliness Is Associated With Lower Self- and Clinician-Rated Levels of Personality Functioning

Personality disorders (PDs) are associated with interpersonal dysfunction, loneliness, and reduced social embeddedness. This study investigates loneliness and social network size in association with self- and clinician-rated personality functioning regarding the DSM-5's Alternative Model for Personality Disorders (AMPD). Eighty psychiatric inpatients including participants with and without PDs completed the Semi-structured Interview for Personality Functioning, the Level of Personality Functioning Scale - Brief Form, the UCLA Loneliness Scale, and the Social Network Index. Patients with PDs reported more loneliness and personality dysfunctioning than patients without PDs. Social network size did not differ between patient groups and showed lower correlations with personality functioning compared to loneliness. Loneliness was further associated with deficits in personality functioning. Deficits in distinct AMPD domains and loneliness may constitute transdiagnostically relevant factors that are related and mutually reinforcing. This could be important for identifying patients beyond PD diagnoses who are at risk of poor psychosocial functioning and require tailored psychotherapy.

A re-introduction of the psychodynamic approach to the standard clinical psychology curriculum

OBJECTIVE

There is a strong evidence-base for a psychodynamic approach, supporting primary theoretical tenets as well as the treatment effectiveness. Additionally, there are increasing calls from the field for more individualized treatment for clients, and the lack of training in multiple orientations limits the ability of students in clinical psychology Ph.D. programs in the United States to personalize their treatments. The accumulated evidence-base for contemporary relational psychodynamic theory and therapy places it in good standing to return to the standard clinical psychology curriculum, along with other evidence-based approaches.

METHODS

We use data from the Insider's Guide (which describes clinical Ph.D. programs in the United States) from three time points over 20 years to document the waning psychodynamic approach in clinical psychology programs. We review the scientific evidence for four primary tenets of a contemporary psychodynamic approach: three related to development-from healthy to psychopathological: (1) unconscious processes; (2) internal representations of self and other; (3) dimensional model of psychopathology, and a fourth tenet that builds on these three and is the foundation for a contemporary psychodynamic approach to psychotherapy: (4) therapeutic relationship as a primary mechanism of change.

RESULTS/CONCLUSIONS

Based on the review of the evidence, we make specific recommendations for clinical psychology training programs about how to include a psychodynamic approach in the curriculum.

The social domains organization of mentalizing processes in adolescents: a contribution to the conceptualization of personality function and dysfunction in young people

BACKGROUND

We propose and evaluate a contribution to the conceptualization and assessment of personality functioning based on social domains and mentalizing hypotheses. Social domains are distinct social contexts, such as with acquaintances and friends, with differentiated expectations regarding participants' behaviours and social attributions. The capacity to organize social participation according to these expectations requires the ability, we suggest, to modulate mentalizing processes domain by domain. Drawing on evidence that social domain organization is impaired in borderline personality disorder (BPD) and that hypermentalizing, a heightened interpretation of others' motives, thoughts or emotions, is elevated in adolescent BPD, we hypothesized that hypermentalizing levels in adolescents will vary by social domain and that elevated BPD features will be associated with impairment of this domain organization of hypermentalizing.

METHODS

Measures including the borderline personality features scale for children (BPFSC) and the movie for the assessment of social cognition (MASC) were administered to 171 adolescents aged 12-17 recruited from public schools and community organizations in a large metropolitan area in southwestern United States. Mean hypermentalizing scores were computed for adolescent interpretations of sequences in the MASC focusing on the social domains of acquaintance, friends and romantic interactions.

RESULTS

There was a progressive increase in hypermentalizing scores across the acquaintance, friends and romantic interactions (repeated measures ANOVA, p < .001, all pairwise comparisons, p ≤ .02), which was markedly reduced in the presence of elevated BPD features (interaction term, p = .007).

CONCLUSIONS

Hypermentalizing is organized according to social domain and this organization is impaired in the presence of elevated BPD features. The findings are consistent with the proposal that personality functioning entails a social domains organization of hypermentalizing, which is impaired in personality dysfunction. Identifying mentalizing processes domain by domain has the potential to create a personalized focus for the treatment of adolescents with personality difficulties.

The Self-Concept and Identity Measure in Patients with Personality Disorders: A Psychometric Evaluation and Associations With Identity Processes, Core Domains of Self-Functioning, and Personality Disorder Symptoms

As developmental and clinical research on identity has largely developed in disconnect, scholars recommend adopting a developmental psychopathology perspective on identity, which considers adaptive and pathological identity functioning. Such a perspective has also been introduced in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) Alternative Model for Personality Disorders (AMPD), which suggests that all personality disorders (PDs) are marked by moderate to extreme deficits in self-functioning (i.e., identity and self-direction). The present study aims to validate the Dutch Self-Concept and Identity Measure (SCIM), a 27-item self-report questionnaire that assesses consolidated identity, disturbed identity, and lack of identity, in 153 psychiatric inpatients with PDs (75.2% female; Mage = 31.73). We investigated the factor structure and reliability of the SCIM, and examined associations of SCIM scales with typical identity processes, AMPD domains of self-functioning, and symptoms of all PDs. Results indicated that a 23-item Dutch SCIM produced valid and reliable scores among patients with PDs. Furthermore, SCIM scales were significantly and differentially related to identity commitment processes, ruminative identity exploration, domains of self-functioning, and symptoms of all PDs. Moreover, findings indicated that PDs varied regarding the severity of identity impairment.

Shame-coping clusters: comparisons regarding attachment insecurities, mentalizing deficits, and personality pathology, controlling for general emotion dysregulation

BACKGROUND

General Emotion Dysregulation (GED) is increasingly implicated as an underlying factor in personality pathology; however, the regulation of specific emotions, such as shame, has been relatively overlooked in the literature. We aimed to identify distinct clusters of shame-coping/regulation and compare them regarding attachment insecurities, mentalizing deficits, and personality pathology, controlling for GED.

METHODS

A convenience sample of 600 participants (351 females and 249 males) from the general population with ages ranging from 18 to 65 (M = 33.78, SD = 12.80) completed a battery of self-report instruments, measuring shame-coping styles, GED, attachment insecurities, mentalizing deficits, criteria A and B of the alternative model for personality disorders, and borderline personality traits. A two-stage clustering method was employed, with shame-coping styles as the clustering variables. The identified clusters were then compared for their effects on dependent variables using multivariate and univariate analyses. These comparisons were also performed after controlling for GED.

RESULTS

Multiple determination methods suggested a two-cluster solution: maladaptive and adaptive shame-coping. Attack-self, withdrawal, and attack-other styles were the main discriminators. Compared with the adaptive cluster, the maladaptive cluster was characterized by higher use of maladaptive and lower use of adaptive shame-coping styles. Multivariate analyses demonstrated significant differences for all the between-cluster comparisons, with and without GED as the covariate (p < .001).

CONCLUSIONS

The current study provides evidence for the presence of homogenous clusters of shame-coping in community-based adults. Between-cluster contrasts after controlling for GED suggest that addressing shame-coping could have incremental utility over and above GED.

Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18): Factor Structure, Validity, and Clinical Cut-Offs

The Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18) is the only self-report measure informed by the Level of Personality Functioning (Diagnostic and Statistical Manual of Mental Disorders [5th ed.; DSM-5; American Psychiatric Association, 2013]) Alternative Model of Personality Disorders developed for adolescents. The present investigation includes two studies evaluating the English LoPF-Q 12-18. In Study 1, single-factor and bifactor structures (unidimensional severity criterion and four specific factors: identity, self-direction, empathy, intimacy) were evaluated in an ethnically diverse community sample (N = 453; age 10-18; 57% female). Study 2 used a community control (n = 298; age 10-18; 54.4% female) and clinical sample (n = 94; age 11-18; 58.5% female) to examine reliability, validity, and clinical utility. Study 1 results supported the bifactor model, with a robust general factor and little multidimensionality caused by the group factors, suggesting an essentially unidimensional structure. Study 2 revealed good internal consistency and construct validity and provided clinical cut-offs, supporting the use of the LoPF-Q 12-18 total score in research and clinical applications.

Adverse childhood experiences and personality functioning interact substantially in predicting depression, anxiety, and somatization

Etiological theories on the development of psychopathology often incorporate adverse childhood experiences (ACE) as an important contributing factor. Recent studies suggest personality functioning (PF; i.e., stability of the self and interpersonal relationships) as an important transdiagnostic construct that could be useful in better understanding when persons with ACE do (not) develop psychopathological symptoms. A representative sample of N = 2363 was assessed by questionnaires on ACE, PF (Level of Personality Functioning Scale-Brief Form 2.0), and current symptoms of depression, anxiety, and somatization (Brief Symptom Inventory 18). The interaction between ACE and PF on symptoms was investigated using multiple group models and Bayesian structural equation modeling. ACE were positively associated with psychopathology and PF impairments. The interaction effect between ACE and PF explained incremental variance in current symptoms, ranging from 26% for somatization to 49% for depression with the complete model explaining up to 91% of the latent variance in psychopathology. Our findings indicate a diathesis-stress model with PF as a resource or resilience that may buffer against the development of symptoms in the face of adversity. Treatments of depression and anxiety targeting self and interpersonal functioning therefore may lead to improvements in resilience and relapse prevention.

Investigation of the role of personality traits and emotion regulation on personality functioning in patients with depression/anxiety disorder

The relationship between the dimensional assessment of personality and difficulties in emotion regulation has yet to be made clear. The present study aimed to investigate the role of personality traits and emotion regulation on personality functioning. Difficulties in Emotion Regulation Scale (DERS), Beck Anxiety Inventory, Beck Depression Inventory, Personality Inventory for DSM-5 (PID-5) and Level of Personality Functioning Scale (LPFS) were rated for 220 patients with depression and/or anxiety disorder diagnosis and 100 healthy controls. Stepwise regression analyses (SRA) were used to find potential predictors of personality functioning, and generalized linear analyses (GLA) were used to find mediators between the traits and personality functioning. SRA results in the clinical group showed that higher depression, antagonism, difficulties in impulse control and difficulties in awareness predicted higher levels of dysfunction in personality. According to GLA results in the clinical group, the impulse subscale of DERS partially mediated the relationship between antagonism and level of impairment in personality functioning. Our results indicate that certain emotion regulation styles and personality traits play an important role in predicting personality functioning in the clinical sample of depression and anxiety patients. Future studies should focus on specific emotion dysregulation strategies and broaden the dimensional personality literature in different samples.

Impaired Personality Functioning in Children and Adolescents Assessed with the LoPF-Q 6-18 PR in Parent-Report and Convergence with Maladaptive Personality Traits and Personality Structure in School and Clinic Samples

To investigate if the Personality Disorder (PD) severity concept (Criterion A) of the ICD-11 and DSM-5 AMPD is applicable to children and adolescents, following the ICD-11 lifespan perspective of mental disorders, age-specific and informant-adapted assessment tools are needed. The LoPF-Q 6-18 PR (Levels of Personality Functioning Questionnaire Parent Rating) was developed to assess Impaired Personality Functioning (IPF) in children aged 6-18 in parent-reported form. It is based on the established self-report questionnaire LoPF-Q 12-18. Psychometric properties were investigated in a German-speaking clinical and school sample containing 599 subjects. The final 36-item version of LoPF-Q 6-18 PR showed good scale reliabilities with 0.96 for the total scale IPF and 0.90-0.87 for the domain scales Identity, Self-direction, Empathy, and Intimacy/Attachment and an acceptable model fit in a hierarchical CFA with CFI = 0.936, RMSEA = 0.078, and SRMR = 0.068. The total score discriminated significantly and with large effect sizes between the school population and (a) adolescent PD patients (d = 2.7 standard deviations) and (b) the younger patients (6-11-year-olds) with internalizing and externalizing disorders (d = 2.2 standard deviations). Informant agreement between parent and self-report was good at 0.47. Good construct validity can be assumed given sound covariation with related measures of psychopathology (CBCL 4-18, STiP-5.1, OPD-CA2-SQ PR) and maladaptive traits (PID5BF+ M CA IRF) in line with theory and matching the result patterns obtained in older samples in self-report. The results suggest that parent-reported assessments of IPF and maladaptive traits are equivalent to self-reported measures for Criterion A and B. Assessing IPF as early as age six might be a valuable step to foster early detection of PD, or maladaptive personality development, respectively individuals at risk.

Are We Thinking about the Same Disorder? A Trifactor Model Approach to Understand Parents' and Their Adolescents' Reports of Borderline Personality Pathology

Multiple informant assessment is the norm when evaluating borderline personality pathology (BPP) in adolescence, especially by including reports from both parents and adolescents. However, these reports tend to be discrepant, and it is unclear how to integrate. The current study used a trifactor model to isolate sources of variance in parents' and adolescents' reports of BPP due to their shared and unique perspectives in a sample of 652 inpatient adolescents (63% female; Mage = 15.31, SD = 1.45) and their parents (81% mothers). Consensus/agreement was characterized by the externalizing features of BPP whereas idiosyncratic views of adolescent BPP covered the full latent BPP construct, suggesting that simple aggregation of parent and adolescent reports is inappropriate. Measurement invariance suggested that unique perspectives were characterized by slightly different operationalizations of BPP and response biases for specific features of BPP. Attachment security and parents' interpersonal problems predicted shared and unique perspectives differently for female and male adolescents. Lastly, we found that shared and unique perspectives differentially predicted interview based BPP, length of stay, and adolescent mentalizing. In sum, findings replicate previous evidence of parent-child informant discrepancy in youth psychopathology, broadly, and provide insights specific to BPP. Discussion includes practical recommendations for assessment and interpretation of BPP assessment.

Key insights from studies on the stability of personality disorders in different age groups

While for decades, temporal stability has been conceived as a defining feature of personality disorders (PDs), cumulative findings appear to question the stability of PDs and PD symptoms over time. However, stability itself is a complex notion and findings are highly heterogenous. Building upon a literature search from a systematic review and meta-analysis, this narrative review aims to capture key findings in order to provide critical implications, both for clinical practice and future research. Taken together, this narrative review revealed that unlike previous assumptions, stability estimates in adolescence are comparable to stability estimates in adulthood and PDs and PD symptoms are not that stable. The extent of stability itself depends yet on various conceptual, methodological, environmental, and genetic factors. While findings were thus highly heterogenous, they all seem to converge in a notable trend towards symptomatic remission, except for high-risk-samples. This challenges the current understanding of PDs in terms of disorders and symptoms and argues instead in favor of the AMPD and ICD-11 reintroducing the idea of self and interpersonal functioning as the core feature of PDs.

A Bridge Between DSM-5 Section II Personality Disorder Criteria and ICD-11 Personality Disorder Trait Domains

The organization of personality pathology into trait domains (vs. specific disorders) in ICD-11 represents an important shift in personality disorder (PD) nosology. However, to facilitate clinical implementation, a bridge is needed between this system and the DSM-5 Section II system familiar to many researchers and clinicians. In this study, individual DSM-5 PD criteria were assigned to ICD-11 trait domains based on the published Clinical Descriptions and Diagnostic Requirements. This scoring scheme was examined empirically alongside DSM-5 PD dimensions (using SIDP ratings from the MIDAS project; N = 2,147 outpatients) in terms of descriptive properties and relations with psychosocial morbidity and functioning. Most PD criteria could be matched to at least one ICD-11 trait domain, indicating considerable cross-system continuity. However, points of incongruity are noteworthy for research and clinical applications. Results provide key information for bridging categorical and dimensional frameworks, indicating that the shift toward trait-based PD models need not be as disruptive as feared.

Narrative Identity within Mentalization-Based Group Therapy for Adolescents: A Feasibility Study

Borderline personality disorder (BPD) is characterized by severe disturbances related to understanding oneself and other people and can be reliably detected and treated in adolescence. In this feasibility study, we aimed to focus on the features of, and changes in, narrative identity throughout the course of Mentalization-Based Treatment in Groups (MBT-G) for adolescents with BPD. Six female patients (M = 15.2, SD = 0.75) joined between 16 and 31 (M = 23.83) MBT g sessions. The narrated events within each session across sessions were coded for themes of agency and communion and the narrated reactions were coded for personality functioning. The patients and their parents also completed several self-report measures before and after therapy. Themes of diminished agency and communion were identified, with communion as the dominating theme. When comparing the patients' first five sessions with their last five sessions, there was an increase in themes related to agency and decreased in communion. The narrated reactions were dominated by themes related to thwarted self-functioning and primarily identity, although intimacy was also present. Patients improved in terms of self-reported functioning and internalizing and externalizing behavior before and after end of treatment. The importance of narration in BPD (group) therapy is discussed alongside clinical implications.

Improvement of personality functioning among people treated within personality disorder mental health services. A longitudinal, observational study

Objective

Evidence-based personality disorder (PD) treatments are dominated by interventions targeting Borderline PD, although clinical populations characteristically include different PD features and severity. Personality functioning is a new concept intended to capture common features across PDs. This study aimed to investigate longitudinal improvement of personality functioning in a clinical sample assigned to PD treatment.

Method

An observational, large, longitudinal study of patients in PD treatments on specialist mental health service levels (N = 1,051). DSM-5 PDs were systematically assessed on referral. Personality functioning was repeatedly assessed (LPFS-BF-2.0), supplemented by symptom distress (anxiety: PHQ-GAD-7, depression: PHQ-9), and social/occupational activity (WSAS, work/study activity). Statistics were linear mixed models.

Results

Thirty per cent had personality difficulties below PD threshold. Among PDs, 31% had Borderline (BPD), 39% Avoidant (AvPD), 15% not otherwise specified, 15% other PDs, and 24% > one PD. More severe initial LPFS-BF was associated with younger age, presence of PD and increasing number of total PD criteria. Across PD conditions, LPFS-BF, PHQ-9 and GAD-7 improved significantly (overall effect size 0.9). Mean duration of PD treatment was 15 (SD 9) months. Drop-out rates were low (12%). LPFS-BF improvement-rates were higher for BPD. Younger age was moderately associated with slower PHQ-9 improvement. Work/study activity was initially poor, poorer levels associated with AvPD and younger age, and improvement was non-significant across PD conditions. AvPD was associated with slower WSAS improvement-rates.

Conclusion

Personality functioning improved across PD conditions. The results highlight BPD improvements. The study points to challenges concerning AvPD treatment, poor occupational activity and age-related differences.

Personality traits as risk factors for relapse or recurrence in major depression: a systematic review

Background

Major depressive disorder (MDD) is highly recurrent. Identifying risk factors for relapse in depression is essential to improve prevention plans and therapeutic outcomes. Personality traits and personality disorders are widely considered to impact outcomes in MDD. We aimed to evaluate the role of personality aspects in the risk of relapse and recurrence in MDD.

Method

A PROSPERO-registered systematic review was conducted using Medline, Embase, PsycINFO, Web of Science and CINAHL as data sources, together with hand searching of four journals over the five years till 2022. There was independent abstract selection, quality assessment and data extraction from each study.

Results

Twenty two studies me t eligibility criteria involving 12,393 participants. Neurotic personality features are significantly associated with the risk of relapse and recurrence of depression, though the data is not uniform. There is some, though limited, evidence that borderline, obsessive-compulsive and dependent personality traits or disorders increase the risk for relapse in depression.

Limitations

The small number, in addition to the methodological heterogeneity of the included studies, did not allow further analysis, such as meta-analysis.

Conclusion

People with high neuroticism and dependent personality traits, borderline personality disorder or obsessive-compulsive personality disorder, compared to those without, may be at a higher risk of experiencing relapse or recurrence of MDD. Specific and targeted interventions may potentially reduce relapse and recurrence rates in these groups and could improve outcomes.

The stability of personality disorders and personality disorder criteria: A systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up. Effect sizes included proportion of enduring cases (i.e., diagnostic stability), test-retest correlations (i.e., dimensional rank-order stability), and within-group standardized mean differences (i.e., dimensional mean-level stability), based on the first and last available measurement occasion. From an initial pool of 1473 studies, 40 were included in our analyses, covering 38,432 participants. 56.7% maintained the diagnosis of any PD, and 45.2% maintained the diagnosis of borderline PD over time. Findings on the dimensional mean-level stability indicate that most PD criteria significantly decreased from baseline to follow-up, except for antisocial, obsessive-compulsive, and schizoid PD criteria. Findings on the dimensional rank-order stability suggested moderate estimates, except for antisocial PD criteria, which were found to be high. Findings indicated that both PDs and PD criteria were only moderately stable, although between study heterogeneity was high, and stability itself depended on several methodological factors.

Mentalization in Typically and Atypically Developing Iranian Children and Its Associations with Age, Sex, and Externalizing/Internalizing Symptoms

Mentalization refers to the ability to understand the mental states of oneself and those of others that motivate action and behavior. Mentalization has generally been linked to adaptive development and healthy functioning whereas diminished mentalization has been associated with maladaptive development and psychopathology. The vast majority of research on mentalization and developmental trajectories, however, is based on Western countries. The overall aim of this study was therefore to examine mentalizing abilities in a novel sample of 153 typically developing and atypically developing Iranian children (Mage = 9.41, SDage = 1.10, Range = 8–11, 54.2% females) recruited from a primary school and health clinic in Tehran. The children completed semi-structured interviews that were later transcribed and coded for mentalization. The parents provided reports on internalizing and externalizing symptoms, demographic information, and all formal diagnoses of the children. The results pointed at general age and sex differences across the two groups. Older children showed more adaptive mentalization compared to the younger children; boys and girls used different mentalizing strategies when facing difficult situations. The typically developing children were better at mentalizing than the atypically developing children. Finally, more adaptive mentalization was associated with lower externalizing and internalizing symptoms among all children. The findings of this study contributes with expanding mentalization research to also encompass non-Western populations and the results hold crucial educational and therapeutic implications.

Evaluating a Comprehensive Model of Euthymia

INTRODUCTION

In research and treatment of mood disorders, "euthymia" traditionally denotes the absence of clinically significant mood disturbance. A newer, expanded definition of euthymia also includes positive affect and psychological well-being.

OBJECTIVE

We aimed to test this comprehensive model of euthymia and estimate the coherence and predictive power of each factor in the model.

METHODS

Community-dwelling adults (N = 601), including both mental health outpatients and non-patients at high risk for personality pathology, completed a battery of interviews and questionnaires at time 1. Most (n = 497) were reassessed on average 8 months later (time 2). We modeled euthymia using standard mood, personality, and psychosocial functioning assessments rather than measures designed specifically for euthymia.

RESULTS

The hypothesized model of euthymia was supported by confirmatory factor analysis: specific measures loaded on three lower order factors (mood disturbance, positive affect, and psychological well-being) that reflected general euthymia at time 1. Each factor (general euthymia plus lower order factors) demonstrated moderately strong concurrent (time 1) and predictive (time 1-2) correlations with outcomes, including employment status, income, mental health treatment consumption, and disability. Compared to positive affect and psychological well-being, mood disturbance had stronger incremental (i.e., nonoverlapping) relations with these outcomes.

CONCLUSIONS

Support for a comprehensive model of euthymia reinforces efforts to improve assessment and treatment of mood and other disorders. Beyond dampening of psychological distress, euthymia-informed treatment goals encompass full recovery, including enjoyment and meaning in life.

Nature and Assessment of Personality Pathology and Diagnosis

This article demonstrates the contribution of Otto Kernberg's object relations theory of personality pathology to the current understanding of the nature and assessment of personality pathology and diagnosis. The article introduces recent advances in psychiatric nosology and presents differing views on the meaning of the general severity criterion common to all personality pathology (i.e., level of personality functioning as described in criterion A of the Alternative DSM-5 Model for Personality Disorders). Next, the significance of Kernberg's theory to recent nosological advances is discussed, with a focus on two important features: first, a definition of personality that goes beyond signs and symptoms to include structural motivational components, in the domains of self- and interpersonal functioning, that are common to all personality manifestations and that fulfill an intrapsychic, organizing function; second, identity formation and consolidation as the ultimate end point of healthy personality functioning. That these cornerstone features of Kernberg's theory, articulated more than 50 years ago, align with the most up-to-date conceptualization of personality pathology confirms that Kernberg's theory represents an idea whose time has finally come.

Examining individual differences in personality trait changes after negative life events

Personality traits can change throughout the entire life span, but people differ in their personality trait changes. To better understand individual differences in personality changes, we examined personal (personality functioning), environmental (environmental changes), and event-related moderators (e.g., perceived event characteristics) of personality trait changes. Therefore, we used a sample of 1069 participants who experienced a negative life event in the last 5 weeks and assessed their personality traits at five measurement occasions over 6 months. Employing preregistered multilevel lasso estimation, we did not find any significant effects. While exploratory analyses generally confirmed this conclusion, they also identified some effects that might being worth to be considered in future research (e.g., perceived impact and perceived social status changes were associated with changes in agreeableness after experiencing a relationship breakup). In total, our moderators explained less than 2% of variance in personality traits. Nonetheless, our study has several important implications for future research on individual differences in personality change. For example, future research should consider personal, environmental, and event-related moderators, use different analytical methods, and rely on highly powered samples to detect very small effects.

How can the DSM-5 alternative model of personality disorders advance understanding of depression?

BACKGROUND

The DSM-5 introduced an alternative model of personality disorder (AMPD) that includes personality dysfunction plus maladaptive-range traits. This study clarifies relations of depression diagnoses and symptoms with AMPD personality pathology.

METHOD

Two samples (Ns 402 and 601) of outpatients and community-dwelling adults completed four depression (criteria met for major depressive disorder and dysthymia; dysphoria and low well-being scales), ten trait (two scales for each of five domains-negative affectivity, detachment, disinhibition, antagonism, psychoticism), and eight dysfunction (four scales for each of two domains-self- and interpersonal pathology) measures. Diagnoses were made using a semi-structured interview; other measures were self-reports. We quantified cross-sectional relations between depression and personality pathology with correlation and multiple regression analyses.

RESULTS

Collectively (median R²; ps < 0.0001), the trait (0.46) and dysfunction (0.50) scales predicted the depression measures strongly, with most predictive power shared (0.41) between traits and dysfunction. However, trait and dysfunction scales altogether predicted depression (median R² = 0.54) more strongly than either domain alone, ps < 0.0001. Participants with depression diagnoses showed elevations on all nonadaptive trait and personality dysfunction measures, particularly negative temperament/affectivity and self-pathology measures.

LIMITATIONS

Generalization of findings to other populations (e.g., adolescents), settings (e.g., primary care), and measures (e.g., traditional personality disorder diagnoses) is uncertain. Cross-sectional analyses did not test changes over time or establish causality.

CONCLUSIONS

The AMPD is highly relevant to depression. Assessment of personality pathology, including both personality dysfunction and maladaptive-range traits, stands to advance understanding of depression in adults.

Operationalizing intimacy and identity aspects of personality functioning in relation to personality disorder in adolescents

According to dimensional models of personality pathology, deficits in interpersonal (intimacy and empathy) and self (identity and self-direction) function (Criterion A) are core to all personality disorders. These aspects of personality functioning (Criterion A) have seldom been evaluated for how they might relate to one another in the context of personality pathology in adolescents. Moreover, the use of performance-based measures to evaluate aspects of Criterion A function remains an untapped resource. Therefore, the present study aimed to evaluate relations between two features of Criterion A, maladaptive intimacy and maladaptive (or diffused) identity, in adolescence. For intimacy, we leverage a performance-based approach to studying intimacy, operationalized in a developmentally relevant way (perceived parental closeness). For identity, we rely on a validated self-report measure of identity diffusion. We examined the relationship between these features with each other and their relations with borderline features. Additionally, we explored whether identity diffusion mediated the expected relationship between perceived parental closeness and borderline features. We hypothesized that greater distance in perceived parental closeness would be associated with higher levels of borderline features, as well as higher levels of identity diffusion, and that identity diffusion would account for the relationship between intimacy and personality pathology. The sample included 131 inpatient adolescents (M _age = 15.35, 70.2% female). Results indicated that intimacy, operationalized as perceived parental closeness, with both mothers and fathers was significantly associated with levels of identity diffusion and borderline features. In addition, greater feelings of closeness with parents were associated with lower severity of borderline features via healthier identity function. Implications of the results, limitations, and future directions are discussed.

Personality Disorder Diagnoses in ICD-11: Transforming Conceptualisations and Practice

Background

Until the advent of the ICD-11, classification of personality disorders was based on categorical prototypes with a long history. These prototypes, whilst familiar, were not based in the science of personality. Prototypical classifications were also complex to administer in non-specialist settings requiring knowledge of many signs and symptoms.

Method

This article introduces the new structure of ICD-11 for personality disorders, describing the different severity levels and trait domain specifiers. Case studies illustrate the main aspects of the classification.

Results

The new ICD-11 system acknowledges the fundamentally dimensional nature of personality and its disturbances whilst requiring clinicians to make categorical decisions on the presence or absence of personality disorder and severity (mild, moderate or severe). The connection between normal personality functioning and personality disorder is established by identifying five trait domain specifiers to describe the pattern of a person's personality disturbance (negative affectivity, detachment, dissociality, disinhibition, and anankastia) that connect to the Big 5 personality traits established in the broader study of personality.

Conclusions

Whilst new assessment measures have been and are in development, the success of the new system will rely on clinicians and researchers embracing the new system to conceptualise and describe personality disturbances and to utilise the classification in the investigation of treatment outcome.

Adolescent borderline personality disorder: Does early intervention 'bend the curve'?

OBJECTIVE

The Global Alliance for Prevention and Early Intervention for Borderline Personality Disorder (BPD) proposed a major change for youth mental health services. The Alliance recommended that early detection and specialised treatment for youth BPD becomes a major focus of their clinical activities. Since structured psychotherapies for BPD are complex and lengthy, this proposal has significant implications for youth policy, planning and resource allocation. Our commentary addresses whether BPD is diagnosable and treatable in youth, and whether early intervention results in longer-term benefits.

CONCLUSION

People diagnosed with BPD are highly heterogeneous and experience high levels of comorbidity. The low quality of the evidence for the treatment of BPD in adolescence limits our ability to develop evidence-based guidelines. Accordingly, there is no clear case for BPD early intervention as a major component of youth mental health services. The introduction of ICD-11 classification system may facilitate further empirical studies of personality disorders in adolescence and emerging adulthood.

The Development of Criterion A Personality Pathology: The Relevance of Childhood Social Functioning for Young Adult Daily Self-Functioning

The DSM-5 alternative model for the diagnosis of personality disorders (AMPD) states that self- and interpersonal (Criterion A) dysfunction is necessary to diagnose a personality disorder, qualified by maladaptive personality trait profiles (Criterion B). This study tested whether childhood maladaptive personality traits predict interpersonal dysfunction during adolescence, which further predicts lower self-functioning in young adulthood. A mixed clinical-community sample of 157 10-year-olds participated for ten years. Social problems and personality traits were rated by parents at age 10 and 12. At age 20, young adults completed 14 daily ratings of self-functioning. Traits of emotional instability and disagreeableness predicted social problems and self-problems. Social problems predicted worse self-functioning in adulthood. An indirect effect of childhood narcissistic traits on higher levels of self-functioning via lower levels of social problems was found. Results are discussed in terms of their contribution to our understanding of the AMPD from a developmental perspective.
