Abstract
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.

Abstract
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.

Abstract
Personality disorders (PDs) are associated with an inferior quality of life, poor health, and premature mortality, leading to heavy clinical, familial, and societal burdens. The International Classification of Diseases-11 (ICD-11) makes a thorough, dramatic paradigm shift from the categorical to dimensional diagnosis of PD and expands the application into adolescence. We have reviewed the recent literature on practical implications, and severity and trait measures of ICD-11 defined PDs, by comparing with the alternative model of personality disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), by mentioning the relevance in forensic and social concerns, and by referencing the developmental implication of life span, especially in adolescence. Study results strongly support the dimensional utility of ICD-11 PD diagnosis and application in adolescence which warrants early detection and intervention. More evidence-based research is needed along the ICD-11 PD application, such as its social relevance, measurement simplification, and longitudinal design of lifespan observation and treatment.

Abstract
With the implementation of new dimensional models of personality disorder (PD) in the DSM-5 and ICD-11, several investigators have developed and evaluated the psychometric properties of measures of severity. The diagnostic accuracy of these measures, an important cross-cultural metric that falls between validity and clinical utility, remains unclear. This study aimed to analyze and synthesize the diagnostic performance of the measures designed for both models. For this purpose, searches were carried out using three databases: Scopus, PubMed, and Web of Science. Studies that presented sensitivity and specificity parameters for cut-off points were selected. There were no restrictions on the age and gender of the participants nor on the reference standard used or the settings. Study quality and synthesis were assessed using QUADAS-2 and MetaDTA software, respectively. Twelve studies were eligible covering self-reported and clinician-rated measures based on the ICD-11 and DSM-5 PD severity models. A total of 66.7% of the studies showed a risk of bias in more than 2 domains. The 10th and 12th studies provided additional metrics, resulting in a total of 21 studies for evidence synthesis. Adequate overall sensitivity and specificity (Se = 0.84, Sp = 0.69) of these measures were obtained; however, the cross-cultural performance of specific cut-off points could not be assessed due to the paucity of studies on the same measure. Evidence suggests that patient selection processes should mainly be improved (avoid case-control design), use adequate reference standards, and avoid only reporting metrics for the optimal cut-off point.

Cervantes BR, Kerr S, Vanwoerden S, Sharp C. Operationalizing intimacy and identity aspects of personality functioning in relation to personality disorder in adolescents. Front Psychiatry 2023; 14:1153274.

Abstract
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.

Maladaptive Self- and Interpersonal Functioning Increments General Psychiatric Severity in the Association with Adolescent Personality Pathology. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10010120.

Abstract
Dimensionalized diagnostic systems, especially the entry criterion of maladaptive self and interpersonal functioning, hold particular advantages for the downward extension of personality pathology to young persons, but require conceptual clarification. The current study evaluated the distinctiveness of maladaptive self and interpersonal functioning by examining its incremental value over and above general psychiatric severity in the association with personality pathology. A community sample of N = 419 youth (50.4% female; Mage = 11.91, SD = 1.19) between the ages of 10 and 14 completed measures of maladaptive self- and interpersonal functioning, general psychiatric severity (internalizing-externalizing spectrum), and personality pathology. Results showed that, as expected, maladaptive self- and interpersonal functioning incremented general psychiatric severity in the association with personality pathology in adolescents. Results contribute to the literature base illustrating the value of the entry criterion of the ICD-11 and AMPD diagnostic system.

Borderline Personal Disord Emot Dysregul 2022; 9:31.

Abstract
BACKGROUND The dimensional approach to personality pathology opens up the possibility to investigate adolescence as a significant period for the development of personality pathology. Recent evidence suggests that symptoms of personality pathology may change during adolescence, but the negative consequences such as impaired social functioning persist later on in life. Thus, we think that problems in social functioning may further predict personality impairments. The current study aimed at investigating the role of relationship quality with parents and peers for the prediction of the level of personality functioning across adolescence. We hypothesized that 1) relationship quality with both parents and peers will significantly account for the level of personality functioning in adolescence and 2) the importance of relationship quality with peers for the relation to impairments in personality functioning will increase with age. METHODS A community sample consisting of 855 adolescents aged 11-18 (M = 14.44, SD = 1.60; 62.5% female) from different regions in Lithuania participated in this study. Self-report questionnaires included the Levels of Personality Functioning Questionnaire to investigate personality impairments and the Network of Relationships Questionnaire to assess the quality of dyadic relationships. RESULTS Discord in the parent, but not peer relationships, was related to a more severe level of personality functioning across adolescence. Lower levels of closeness with parents accounted for higher impairments in personality functioning. The importance of closeness with peers for the explanation of the level of personality functioning increased with age. CONCLUSIONS During the sensitive period for the development of a personality disorder, relationship quality with the closest adults and peers both remain important for the explanation of impairments in personality functioning.
