Background: Extensive psychiatric hospitalization due to repeated severe self-harm (SH), is a poorly researched area, but a challenge within health services (HS). Recent studies have demonstrated high levels of involuntary treatment among patients with severe personality disorder (PD) and complex comorbidity. Keeping focus on extensively hospitalized SH patients, this study aimed to investigate patients' and clinicians' evaluation of HS and treatment alliance.

Background: Severe self-harm leading to extensive hospitalization generates extreme challenges for patients, families, and health services. Controversies regarding diagnoses and health care often follow. Most evidence-based treatments targeting self-harm are designed for borderline personality disorder (BPD).

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 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).

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.

The Level of Personality Functioning Scale (LPFS) of the Alternative Model for Personality Disorders (AMPD) was formulated to assess the presence and severity of personality disorders (PDs). Moderate impairment (Level 2) in personality functioning, as measured by the LPFS, was incorporated into the AMPD as a diagnostic threshold for PD in Criterion A of the general criteria, as well as for the "any two areas present" rule for assigning a specific PD diagnosis. This study represents the first evaluation of the diagnostic decision rules for Criterion A, in a clinical sample ( = 282).

The alternative model for personality disorders (AMPD) in the defines personality functioning by assessment of impairment in Identity and Self-direction (Self component) and in Empathy and Intimacy (Interpersonal). These four domains constitute the Level of Personality Functioning Scale, a trans-diagnostic measure of PD severity. The association between the Level of Personality Functioning Scale and psychosocial impairment based on other previously established psychosocial functioning instruments has not been reported.

Background: Norway authorised out-patient commitment in 1961, but there is a lack of representative and complete data on the use of out-patient commitment orders.

Aims: To establish the incidence and prevalence rates on the use of out-patient commitment in Norway, and how these vary across service areas. Further, to study variations in out-patient commitment across service areas, and use of in-patient services before and after implementation of out-patient commitment orders.

Purpose: Despite one of the longest histories of using Outpatient Commitment (OC), little is known about the use in the Norwegian context. Reporting from the Norwegian Outpatient Commitment Study, this article aims to: establish the profile of the OC population in Norway; ascertain the legal justification for the use of OC and what OC involves for patients; investigate possible associations between selected patient and service characteristics and duration of OC, and; explore potential differences based on gender or rurality.

Methods: A retrospective multi-site study, extracting data from the medical records of all patients on OC in six large regional hospitals in 2008-12, with detailed investigation over 36 months of the subsample of patients on first ever OC-order in 2008-09.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) presents an alternative model for personality disorders in which severity of personality pathology is evaluated by the Level of Personality Functioning Scale (LPFS). The Structured Interview for the DSM-5 Alternative Model for Personality Disorders, Module I (SCID-5-AMPD I) is a new tool for LPFS assessment, but its interrater reliability (IRR) has not yet been tested. Here we examined the reliability of the Norwegian translation of the SCID-5-AMPD I, applying two different designs: IRR assessment based on ratings of 17 video-recorded SCID-5-AMPD I interviews by five raters; and test-retest IRR based on interviews of 33 patients administered by two different raters within a short interval.
