Personality disorders: the impact of severity on societal costs.

Personality disorders (PDs) are associated with high levels of societal costs. However, previous research has found limited or no evidence of unique contributions of individual PD categories on the overall level of societal costs. Recent research supports the validity of PD as a dimensional construct, and PD severity may be a better predictor of societal costs than specific PD categories.

Group-based comprehensive behavioral intervention for tics (CBIT) for adults with Tourette syndrome or chronic tic disorders: A pilot study.

Comprehensive behavioral intervention for tics (CBIT) administered individually is an effective treatment for tics. However, the effectiveness of CBIT administered in groups for adults with Tourette syndrome and chronic tic disorders has not been investigated yet. This pilot study examined the effectiveness of group-based CBIT with respect to reduction of tic severity and tic-related impairment, as well as improvement of tic-related quality of life.

A systematic review of measurement uncertainty visualizations in the context of standardized assessments.

This systematic review summarized findings of 29 studies evaluating visual presentation formats appropriate for communicating measurement uncertainty associated with standardized clinical assessment instruments. Studies were identified through systematic searches of multiple databases (Medline, Embase, PsycInfo, ERIC, Scopus, and Web of Science). Strikingly, we found no studies which were conducted using samples of clinicians and included clinical decision-making scenarios.

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.

Evaluating the Construct Validity of the Norwegian Version of the Level of Personality Functioning Scale - Brief Form 2.0 in a Large Clinical Sample.

The Level of Personality Functioning - Brief Form 2.0 (LPFS-BF 2.0) is a 12-item self-report questionnaire developed to gain a quick impression of the severity of personality pathology according to the DSM-5 Alternative Model for Personality Disorders (AMPD).

Visualizing Uncertainty to Promote Clinicians' Understanding of Measurement Error.

Measurement error is an inherent part of any test score. This uncertainty is generally communicated in ways that can be difficult to understand for clinical practitioners. In this empirical study, we evaluate the impact of several communication formats on the interpretation of measurement accuracy and its influence on the decision-making process in clinical practice.

Do Flexible Administration Procedures Promote Individualized Clinical Assessments? An Explorative Analysis of How Clinicians Utilize the Funnel Structure of the SCID-5-AMPD Module I: LPFS.

The current study examined clinicians' utilization of the SCID-5-AMPD-I funnel structure. Across 237 interviews, conducted as part of the NorAMP study, we found that clinicians administered on average 2-3 adjacent levels under each subdomain, effectively administering only about 50% of available items. Comparing administration patterns of interviews, no two interviews contained the exact same set of administered items.

The Norwegian network for personality disorders - development, contributions and challenges through 30 years.

Background: Established in 1992, the Norwegian Network for Personality Disorders (The Network) is a clinical research collaboration of specialist mental health and addiction services in Norway. Its primary focus is to facilitate systematic and relevant clinical assessment for patients with personality disorder and evaluate progress in psychotherapeutic treatment. However, large-scale data registers for personality disorder are still unique.

Personality Disorders as a Possible Moderator of the Effects of Relational Interventions in Short-Term Psychoanalytic Psychotherapy with Depressed Adolescents.

Unlabelled: A significant proportion of adolescents suffering from major depressive disorder (MDD) are likely to have a co-morbid personality disorder (PD). Short-term psychoanalytic psychotherapy (STPP) was found to be one treatment of choice for adolescents suffering from MDD.

Background: The first experimental study of transference work-in teenagers (FEST-IT) demonstrated the efficaciousness of transference work in STPP with adolescents suffering from MDD.

Avoidant and borderline personality disorder patients during the first Covid-19 wave in Norway - a survey-based comparison of therapy changes and patients' accommodations.

Background: Patients with personality disorders (PDs) often have insecure attachment patterns and may be especially vulnerable to abrupt treatment changes. Patients with borderline PD (BPD) are often considered vulnerable to treatment interruption due to chronic fear of abandonment. Nonetheless, other PDs are poorly investigated.

Is the alternative model for personality disorders able to capture avoidant personality disorder according to Section II of the DSM-5? A systematic review.

This review aims at examining the continuity between the categorical model for personality disorders (PDs) as defined by Section II of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and the alternative model for personality disorders (AMPD) with respect to Section II avoidant personality disorder (AvPD). Because the Criterion A of the AMPD, that is, the Level of Personality Functioning Scale (LPFS), is a prerequisite for a PD diagnosis, only studies assessing the LPFS were included, whether or not the Criterion B, that is, pathological personality traits, were assessed as well. A total of 13 studies met the inclusion criteria, with 6 studies comprising community/undergraduate samples and 7 studies comprising clinical samples.

The Incremental Utility of Criteria A and B of the DSM-5 Alternative Model for Personality Disorders for Predicting DSM-IV/DSM-5 Section II Personality Disorders.

The DSM-5 Alternative Model for Personality Disorders (AMPD) includes two main criteria: moderate or greater impairment in personality functioning (Criterion A) and the presence of one or more pathological personality traits (Criterion B). The aim of the study was to investigate the incremental utility of Criteria A and B for predicting DSM-5 Section II personality disorders (PD). The sample (N = 317) consisted of three well-defined groups: non-clinical participants (n = 35), psychiatric patients with PD (n = 193), and without PD (n = 83).

Do Sleep Disturbances Improve Following Psychoanalytic Psychotherapy for Adolescent Depression?

Sleep disturbance is often a prominent symptom in adolescents diagnosed with major depressive disorder (MDD). Recent evidence indicates that short-term psychoanalytic psychotherapy (STPP) for depression may have an effect in reducing co-occurring sleep disturbance in youth. It is unknown if transference work (exploration of the patient-therapist relationship) has an additional effect in reducing sleep disturbance.

Norwegian Clinicians' Experiences of Learnability and Usability of SCID-II, SCID-5-PD and SCID-5-AMPD-I Interviews: A Sequential Multi-Group Qualitative Approach.

The DSM-5 presents two competing diagnostic frameworks for personality disorders: the standard categorical model and the Alternative Model of Personality Disorders (AMPD). The AMPD was initially criticized for being too complex and theory laden for clinical implementation. Though inter-rater reliability studies have contested initial claims of the model's complexity, little attention has been paid to how clinicians experience the usability and learnability of either model.

Vulnerability of personality disorder during COVID-19 crises: a multicenter survey of mental and social distress among patients referred to treatment.

Background: Relational and emotional problems, dysregulation, self-harming or substance abuse often characterize personality disorders (PD). In Norway, COVID-19 restrictions led to an abrupt shutdown of services from 12 March 2020 also including specialized PD treatments.

Aims: The objective of this study was to investigate social and mental distress among patients with PDs during the first COVID-19 wave.

Vulnerability of personality disorder during the Covid-19 crises - a multicenter survey of treatment experiences among patients referred to treatment.

Background: The societal shutdown due to the Covid-19 pandemic involved mental health services for personality disorder (PD) and was introduced from 12 March 2020 in Norway. Rapid implementation of treatment modifications was required for patients typically characterized by insecure attachment and vulnerability to separation.

Aim: To investigate immediate reactions to the shutdown of services; alternative treatment received; and differences related to age in a clinical sample of patients with PD.

More is more: Evidence for the incremental value of the SCID-II/SCID-5-PD specific factors over and above a general personality disorder factor.

Currently, 3 competing conceptualizations of personality dysfunction can be distinguished: the () categorical model delineating 10 distinct types of personality disorders (PDs); the alternative model for PDs ( Section III), which assesses personality functioning and traits separately; and the , conceptualization, which provides 1 single code for the presence of a PD (which is based on problems in functioning) as well as codes that specify the level of the disorder (mild/moderate/severe), and prominent trait domains or patterns (5 domains and 1 pattern). The current study aims to assess the incremental value of the PDs over and above a global personality dysfunction factor, using expert ratings obtained with the Structured Clinical Interview for PDs and the Structured Clinical Interview for PDs interview in a large sample of clinical patients ( = 3,851). All estimated bifactor models provided adequate fit to the data.

The first experimental study of transference work-in teenagers (FEST-IT): a multicentre, observer- and patient-blind, randomised controlled component study.

Background: Little is known about the influence on outcome of exploration of the patient-therapist relationship (that is, transference work) in psychoanalytic psychotherapy. We hypothesized that depressed adolescents would have better long-term effects from psychoanalytic psychotherapy with than without transference work.

Methods: Depressed adolescent (16 to 18 years) were recruited in health authority funded out-patient clinics in Oslo and Vestfold County, Norway.

The Test-Retest Reliability of Heart Rate Variability and Its Association With Personality Functioning.

Heart rate variability (HRV) is a widely used non-invasive index of emotion regulation ability. The main aim of our study was to investigate the relationship between HRV and level of personality functioning in a clinical sample, most of whom had a personality disorder. Our secondary aim was to examine the test-retest reliability of HRV in our sample as there is a lack of knowledge regarding the test-retest reliability in psychiatric populations.

A Psychometric Analysis of the Structured Clinical Interview for the Alternative Model for Personality Disorders Module I (SCID-5-AMPD-I): Level of Personality Functioning Scale.

The current study aims to examine the psychometric properties of the Structured Clinical Interview for the Alternative Model for Personality Disorders Module I (SCID-5-AMPD-I) assessing the Level of Personality Functioning Scale (LPFS) in a heterogeneous sample of 282 nonpsychotic patients. Latent variable models were used to investigate the dimensionality of the LPFS. The results indicate that the LPFS, as assessed by the SCID-5-AMPD-I, can be considered as a unidimensional construct that can be measured reliably across a wide range of the latent trait.

A multi-center psychometric evaluation of the Severity Indices of Personality Problems 118 (SIPP-118): Do we really need all those facets?

Purpose: The Severity Indices of Personality Problems 118 (SIPP-118) is a self-report questionnaire that aims to measure core components of (mal)adaptive personality functioning that can change over time. In this study, we aimed to assess the facet strength of the 16 facets across three large clinical samples.

Methods: Data from Norwegian and Dutch psychiatric patients were analyzed in this international multi-center study (N = 2814, N = 4751, N = 2217).

Cognitive behavior therapy in early psychosis with a focus on depression and low self-esteem: A randomized controlled trial.

Background: Patients in early phases of psychosis often struggle with depressive symptoms and low self-esteem. The main aims of the present study were to examine whether cognitive behavior therapy (CBT) compared to treatment as usual (TAU) would reduce depressive symptoms (primary outcome) and increase self-esteem (secondary outcome). Furthermore, we wanted to examine whether CBT reduces symptoms measured with the PANSS (positive, negative, cognitive, or excited symptoms) or increases general functioning compared to TAU.
