Psychometric Evaluation of the Norwegian Difficulties in Emotion Regulation Scale in a Multi‐Site Sample of Patients With Personality Disorders and Personality Problems
OBJECTIVE: The validity and psychometric qualities of the Difficulties in Emotion Regulation Scale (DERS) in populations with a broader range of personality disorders (PDs) are still unclear. The aim of the current study was to analyze the factor structure and validity of DERS and two of its short-forms (DERS-SF and DERS-18), their relation to PD features and personality functioning, gender differences, and the overlap between concepts of alexith…
Childhood predictors of avoidant personality disorder traits in adolescence
BACKGROUND: Although it is widely assumed that avoidant personality disorder (AvPD) originates in childhood, there is little prospective research to substantiate this claim. We therefore aimed to determine whether presumed childhood risk factors predict AvPD traits at 16 years. METHODS: A population-based sample (n = 1,077; 50.9% female) from the 2003 and 2004 birth cohorts in Trondheim, Norway was examined biennially from 4 to 16 years. The numb…
Improvement of alexithymia in patients treated in mental health services for personality disorders
Alexithymia is a common problem among patients with PDs and is associated with mental health difficulties and psychosocial dysfunction, with rates varying across PD type and severity. The study demonstrates moderate improvement of alexithymia during treatment in specialized PD mental health services. Further research should evaluate the effectiveness of different treatments and interventions in reducing alexithymia among PD patients
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). The current study evaluated the construct validity and reliability of the Norwegian version of the LPFS-BF 2.0 in a large clinical sample (N = 1673). Dimensionality was examined using confir…
Countertransference, alliance, and outcome in the treatment of patients with personality disorder
The study demonstrates significant associations between negative CTs and lower patient-rated WAI in the early phase of therapy, and a development of increasingly more negative CTs during therapy in treatments which were not completed according to schedule. The results indicate high clinical relevance of monitoring therapeutic relationships in PD treatments. Further research on the emotional and relational quality of psychotherapeutic relationship…
Minding mentalizing - convergent validity of the Mentalization Breakdown Interview
ClinicalTrials.gov ID NCT04157907
Combined group and individual therapy for patients with avoidant personality disorder—A pilot study
This pilot study shows promising results for combined group- and individual therapy for AvPD patients with moderate to severe impairment. Larger scale studies should be conducted to increase empirically based knowledge to guide development of differentiated treatments adapted to patients' various levels of AvPD severity and profiles of personality dysfunction
Mental health disorders, functioning and health-related quality of life among extensively hospitalized patients due to severe self-harm – results from the Extreme Challenges project
The study reveals that severe self-harm inpatients have complex psychopathology and highlights the importance of individualized and thorough assessment among patients with severe and/or repetitive self-harm
Improvement of personality functioning among people treated within personality disorder mental health services. A longitudinal, observational study
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
Social Cognition Capacities as Predictors of Outcome in Mentalization-Based Treatment (MBT)
This study demonstrates considerable variation of social cognitive capacity among BPD patients and good outcomes for patients with mainly ToM errors of hypermentalizing. It also indicates that poorly responding patients may represent a cohort with more complex problems of social cognition and insufficient mentalizing
The relationship between reflective functioning and affect consciousness in patients with avoidant and borderline personality disorders
