Borderline (BPD) and schizotypal personality disorder (SPD) were introduced in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III). However, the clinical differentiation of the 2 diagnoses (e.g., psychotic-like features) was challenging for diagnostic classification and clinical management. With the introduction of the alternative model for personality disorders (AMPD) in DSM-5 Section III, a dimensional approach was proposed, which potentially holds promise for be...
Despite clinical theory suggesting that individuals are largely unaware of personality-related problems (Gallrein et al., 2013; Oltmanns & Powers, 2012); work in this area shows that individuals possess insight into their pathological traits and the impairment they may cause. Individuals generally dislike pathological traits and desire change in the direction of greater adaptivity (Lamkin et al., 2018; Miller et al., 2018). Individuals may also be able to make small, intentional changes in some ...
Young adults presenting with personality disorders (PDs) featuring overcontrol and social inhibition urgently require effective psychological interventions to help them navigate important life transitions. metacognitive interpersonal therapy-group (MIT-G) is a time-limited group program designed to enable individuals to find adaptive solutions to their social difficulties. A small randomized clinical trial (RCT) of MIT-G versus treatment as usual (TAU) was conducted with the primary outcomes of ...
Cluster B personality traits often co-occur with psychopathic traits. However, few investigations have been conducted to understand the high co-occurrence of antisocial (ASPD), borderline (BPD), narcissistic (NPD), and histrionic (HPD) personality disorder traits and psychopathy. The triarchic model of psychopathy is a framework that focuses on dispositional constructs (meanness, boldness, and disinhibition) with neurobiological and developmental correlates that may be particularly useful in elu...
A model of personality pathology including both general and specific components distinguishes severity of personality dysfunction from the characteristic style of its expression. This model has been proposed as an empirically based, dimensional alternative to categorical models. In this study, we evaluated this conceptual structure by examining associations between general and specific features of personality pathology and momentary interpersonal dynamics. By assessing whether dynamic variabilit...
Accumulating evidence supports the reliability and validity of the diagnosis of personality disorders (PDs) in adolescents, but whether the current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), criteria are optimal to capture and help detect emerging PDs in this age-group remains controversial. The Level of Personality Functioning Scale (LPFS), included in the alternative model for personality disorders, may provide a more developmentally sensitive way to identify...
Participants (n = 134) treated in a randomized controlled trial with mentalization-based treatment (MBT) compared with structured clinical management were followed up for 8 years after starting treatment in terms of the initial primary outcome of the trial-namely, suicide attempts, self-harm, and hospitalization-as well as service use and functional outcomes. Patients in the study group were interviewed by research assistants who remained masked to the original group allocation. Interviews were ...
