This commentary critically evaluates the usefulness of the standards employed by Gunderson et al. (2018) for theory evaluation and comparison and calls into question their adequacy, based both on the lack of scientific evidence supporting the assertions these standards imply and on the availability of alternative standard for theory evaluation and comparison. In so doing, the commentary calls for a redefinition of "borderlineness" as well as the use of standard criteria for theory evaluation and comparison...

The present study sought to assess the performance of the Borderline Features (BOR) Scale of the adolescent version of the Personality Assessment Inventory (Morey, 2007b) in 2 high-risk samples: inpatient and justice-involved adolescents. This study is the first to evaluate the BOR scale in high-risk adolescent samples, outside the initial standardization studies. Across both samples (NClinical = 327, NForensic = 151), results indicated good internal consistency. Confirmatory factor analysis indicated poor fit of the 4-factor structure proposed by the measure's authors...

Borderline personality disorder (BPD) in adolescents is highly complex and heterogeneous. Within the disorder, research has suggested the existence of at least two subgroups: one with predominantly internalizing psychopathology features and one with predominantly externalizing psychopathology features. One process that may differentiate these groups is executive functioning (EF), given that poor EF is linked to externalizing psychopathology. Against this background, the current study used a multi-informant approach to examine whether adolescent patients with predominantly externalizing BPD presentations experience greater deficits in EF than adolescent patients with predominantly internalizing presentations...

The identification of theoretically and empirically supported correlates of suicide ideation is important to improve treatment approaches to suicide. This study sought to examine the association between interpersonal trust (theoretically conceptualized as a distal risk marker) and suicide ideation in adolescence. Specifically, it was hypothesized that interpersonal trust would be negatively associated with suicide ideation via perceived burdensomeness and thwarted belongingness (conceptualized as more proximal risk markers)...

The aim of the study was to examine whether Borderline Personality Disorder (BPD) features moderate the relation between dating violence victimization (DVV) experiences and nonsuicidal self-injury (NSSI) in adolescent inpatients. A total of 184 adolescent inpatients completed measures on DVV, BPD features, and NSSI at admission to treatment. Bivariate analyses revealed significant relations between DVV, BPD features, and NSSI. Hierarchical multiple regression analyses demonstrated a moderating effect of BPD features such that in the low BPD features group, more severe DVV was associated with greater NSSI frequency; adolescents in the high BPD group endorsed elevated, though stable, levels of NSSI at all levels of DVV...

Research has just begun to study associations between sexual fluidity and health among cisgender individuals; only one cross-sectional study examined these links among transgender individuals. The goals of the current study were to prospectively examine fluidity in sexual attractions and fluidity in sexual orientation identity, and associations with health-related outcomes. Participants were a community-based sample of 45 transgender men, ages 16-51 years, who had recently begun testosterone, and 95 cisgender individuals (53 women, 42 men), ages 18-55 years, who completed surveys either in-person or via mail...

Research suggests that oxytocin, a neuropeptide implicated in attachment, is a promising clinical tool because it increases affiliation and attachment behaviors, which are reduced in a range of psychiatric disorders. Oxytocin has been recommended as a psychiatric treatment for adolescents, but this remains largely unstudied. Skepticism is warranted, based on mixed findings in adults and absence of data across development. The objective of this study was to examine the effect of intranasal oxytocin on attachment-related and non-attachment-related trust in an interactive game, determining how this effect differs among inpatient adolescents and healthy controls and whether this effect is moderated by attachment security...

Although convergence in parent-youth reports of adolescent psychopathology is critical for treatment planning, research documents a pervasive lack of agreement in ratings of adolescents' symptoms. Attachment insecurity (particularly disorganized attachment) and impoverished reflective functioning (RF) are 2 theoretically implicated predictors of low convergence that have not been examined in the literature. In a cross-sectional investigation of adolescents receiving inpatient psychiatric treatment, we examined whether disorganized attachment and low (adolescent and parent) RF were associated with patterns of convergence in adolescent internalizing and externalizing symptoms...

There is mounting evidence that personality pathology, in particular, borderline pathology is a valid and reliable construct in adolescence, with prevalence, phenomenology, stability and risk factors similar to that of adult borderline personality disorder. Scientific evidence also delineates a marked separation of course and outcome of adolescent borderline personality disorder from other disorders and supports the efficacy of disorder-specific treatment. The current article addresses recent findings in these areas which point to adolescence as a sensitive period for the development for personality pathology...

Background: Insecure attachment is a precursor and correlate of borderline personality disorder. According to the mentalization-based theory of borderline personality disorder, the presence of insecure attachment derails the development of the capacity to mentalize, potentially resulting in borderline pathology. While one prior study found support for this notion in adolescents, it neglected a focus on peer attachment. Separation from primary caregivers and formation of stronger bonds to peers are key developmental achievements during adolescence and peer attachment warrants attention as a separate concept...

OBJECTIVES: Recent work has highlighted the link between acculturative stress and depression/anxiety symptoms among Hispanic young adults, but the nature of these relations is not well understood. The present study aimed to clarify the relation between acculturative stress and depression/anxiety symptoms by examining anxiety sensitivity, globally and via subfactors, as an explanatory variable. METHOD: A cross-sectional sample of 788 Hispanic college students (80...

Adult neurogenesis involves the generation of new neurons, particularly in the dentate gyrus of the hippocampus. Decreased hippocampal neurogenesis has been implicated in both animal models of depression and in patients with major depressive disorder (MDD), despite some inconsistency in the literature. Here, we build upon current models to generate a new testable hypothesis, linking impaired neurogenesis to downstream psychological outcomes commonly observed in MDD. We contend that disruption in adult neurogenesis impairs pattern separation, a hippocampus-dependent function requiring the careful discrimination and storage of highly similar, but not identical, sensory inputs...

The dark triad of personality has traditionally been defined by 3 interrelated constructs, defined as Narcissism, Machiavellianism, and Psychopathy. Although the content of each of these constructs is clearly represented in childhood maladaptive trait measures, no studies have jointly addressed the prospective developmental course of this core set of maladaptive characteristics throughout childhood and adolescence. The current study uses latent growth modeling to explore how early dark traits develop over time, relying on a selected set of 6 childhood maladaptive traits that conceptually cover the adult dark triad...

BACKGROUND: With the publication of DSM 5 alternative model for personality disorders it is critical to assess the components of the model against evidence-based models such as the five factor model and the DSM-IV-TR categorical model. This study explored the relative clinical utility of these models in screening for borderline personality disorder (BPD). METHODS: Receiver operator characteristics and diagnostic efficiency statistics were calculated for three personality measures to ascertain the relative diagnostic efficiency of each measure...

Understanding predictors of adolescent inpatient length of stay (LOS) is important in informing treatment outcomes for this age group. The current literature on adolescent LOS remains limited and has been characterized by methodological limitations. In the study described here, we examined a wide range of predictors for LOS in a psychiatric unit for adolescents (N=285), including severity of disorder (previous hospitalizations, self-harm, cognitive impairment and thought disorder, severe depression, history of trauma), types of psychotropic medication, and diagnoses...

Assessing attachment in adolescents is important due to relations between insecurity and psychopathology. The child attachment interview (CAI) holds promise in this regard, but is time-consuming to code, which may render it inaccessible. The aim of this study was to develop computerized neural network models to predict attachment classifications on the CAI and to determine whether the models could achieve the CAI's benchmark qualification of 80% on reliability training cases. Four hundred and ninety interviews from inpatient adolescents served as model training and testing samples...

While the DSM-5 alternative model of personality disorder (PD) diagnosis allows the field to systematically compare categorical and dimensional classifications, the ICD-11 proposal suggests a radical change by restricting the classification of PDs to one category, deleting all specific types, basing clinical service provision exclusively upon a severity dimension, and restricting trait domains to secondary qualifiers without defining cutoff points. This article reflects broad international agreement about the state of PD diagnosis...
