Abstract
Personality disorders (PDs) are prevalent in about one in every 10 adults. Prior to the introduction of the ICD-10 in Denmark, the incidence rate for PD (including schizotypal) among psychiatric patients was approximately 12% and the prevalence rate 14%.
The aim of the present clinical epidemiology study is to investigate the use of ICD-10 PD as primary and secondary diagnoses in years 1995, 2000 and 2006, comorbid disorders and their relation to age and gender.
The study includes all adult patients admitted to any psychiatric hospital (inpatients and outpatients) in Denmark.
Both incidence and prevalence rates of PD diagnoses decrease over the study period. It is evident that all specific diagnoses significantly decrease or remain stable whereas the unspecified and mixed type significantly increases constituting up to 50% of diagnoses. Emotionally unstable PD stands out as the single most prevalent covering around one third of PD diagnoses. A decrease is found in the prevalence of patients receiving a PD diagnosis as a primary diagnosis, but an increase as a secondary diagnosis (most often as comorbid to depression or anxiety disorder). Differences are found in relation to gender and age.
PDs are among the most prevalent disorders; however, rates are decreasing in psychiatric settings. There seem to be a rather huge gap between clinical evaluation and research data on prevalence of PDs. Clinicians need more education and sufficient time for in-depth personality assessment of PDs in all patient groups.

Abstract
The factor structure of the Millon Clinical Multiaxial Inventory-III (Millon, Millon, Davis, & Grossman, 2006) personality disorder scales was analyzed using multigroup confirmatory factor analysis on data obtained from a Danish (N = 2030) and a Belgian (N = 1210) sample. Two-, three-, and four factor models, a priori specified using structures found by Dyce, O'Connor, Parkins, and Janzen (1997), were fitted to the data. The best fitting model was a four factor structure (RMSEA = .066, GFI = .98, CFI = .93) with partially invariant factor loadings. The robustness of this four-factor model clearly supports the efforts to organize future personality disorder description in a four-factor framework by corroborating four domains that were predominant in dimensional models (Widiger & Simonsen, 2005): Factor 1, 2, 3, and 4 respectively corresponded to emotional dysregulation versus stability, antagonism versus compliance, extraversion versus introversion, and constraint versus impulsivity.

Abstract
Dysfunction in affect regulation is a prominent feature that grossly impairs behavioural and interpersonal domains of experience and underlies a great deal of the psychopathology in borderline personality disorder (BPD). However, no study has yet been published that evaluates the psychometric properties of the translated Danish version of self-report measures sensitive to the different aspects and dimensions of dysfunction in affect regulation prevalent in BPD.
This study comprised a group of women diagnosed with BPD (n = 29) and a comparison group of healthy subjects (n = 29) who reported psychopathology and levels of affective instability, aggression, impulsivity and alexithymia by self-report measures.
Our results demonstrated that women with BPD have significant psychopathology and report significantly higher levels of dysfunction in separate components of affect regulation by self-report measures than the comparison group of healthy subjects. Our results also provided partial support for the psychometric appropriateness and clinical relevance of the translated Danish version of affect regulation measures.
The normative reference range indicated by our results makes the measures useful as a practical assessment tool.

Abstract
The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013a) offers an alternative model for Personality Disorders (PDs) in Section III, which consists in part of a pathological personality traits criterion measured with the Personality Inventory for DSM-5 (PID-5). The PID-5 selfreport instrument currently exists in the original 220-item form, a short 100-item form, and a brief 25-item form. For clinicians and researchers, the choice of a particular PID- 5 form depends on feasibility, but also reliability and validity. The goal of the present study was to examine the psychometric qualities of all 3 PID-5 forms, simultaneously, based on a Danish sample (N = 1376) of 451 psychiatric outpatients and 925 community-dwelling participants. Scale reliability and factorial validity were satisfactory across all 3 PID-5 forms. The correlational profiles of the short and brief PID-5 forms with clinician-rated PD dimensions were nearly identical with that of the original PID-5 (rICC = .99 and .95, respectively). All 3 forms discriminated appropriately between psychiatric patients and community-dwelling individuals. This supports that all 3 PID-5 forms can be used to reliably and validly assess PD traits and provides initial support for the use of the abbreviated PID-5 forms in a European population. However, only the original 220-item form and the short 100-item form capture all 25 trait facets, and the brief 25-item form may be ideally limited to preliminary screening or situations with substantial time restrictions.

Abstract
Information about the cost-effectiveness of early intervention programmes for first-episode psychosis is limited.
To evaluate the cost-effectiveness of an intensive early-intervention programme (called OPUS) (trial registration NCT00157313) consisting of enriched assertive community treatment, psychoeducational family treatment and social skills training for individuals with first-episode psychosis compared with standard treatment.
An incremental cost-effectiveness analysis of a randomised controlled trial, adopting a public sector perspective was undertaken.
The mean total costs of OPUS over 5 years (€123,683, s.e. = 8970) were not significantly different from that of standard treatment (€148,751, s.e. = 13073). At 2-year follow-up the mean Global Assessment of Functioning (GAF) score in the OPUS group (55.16, s.d. = 15.15) was significantly higher than in standard treatment group (51.13, s.d. = 15.92). However, the mean GAF did not differ significantly between the groups at 5-year follow-up (55.35 (s.d. = 18.28) and 54.16 (s.d. = 18.41), respectively). Cost-effectiveness planes based on non-parametric bootstrapping showed that OPUS was less costly and more effective in 70% of the replications. For a willingness-to-pay up to €50,000 the probability that OPUS was cost-effective was more than 80%.
The incremental cost-effectiveness analysis showed that there was a high probability of OPUS being cost-effective compared with standard treatment.

Abstract
BACKGROUND: Early detection programmes aim to reduce the duration of untreated psychosis (DUP) by public education and by prompt access to treatment via active outreach detection teams. AIMS: To determine whether those with first-episode psychosis in an early detection healthcare area with existing referral channels differ from those who access care via detection teams. METHOD: Those with first-episode psychosis recruited via detection teams were compared with those accessing treatment via conventional channels, at baseline and after 3 months of acute treatment. RESULTS: Patients recruited via detection teams are younger males with a longer DUP, a less dramatic symptom picture and better functioning; however they recover more slowly, and have more symptoms at 3-month follow-up. CONCLUSIONS: After establishing low threshold active case-seeking detection teams, we found clear differences between those patients entering treatment via detection teams v. those obtaining treatment via the usual channels. Such profiling may be informative for early detection service development.

Abstract
First episode psychosis (FEP) patients have an increased risk for violence and criminal activity prior to initial treatment. However, little is known about the prevalence of criminality and acts of violence many years after implementation of treatment for a first episode psychosis.
To assess the prevalence of criminal and violent behaviors during a 10-year follow-up period after the debut of a first psychosis episode, and to identify early predictors and concomitant risk factors of violent behavior.
A prospective design was used with comprehensive assessments of criminal behavior, drug abuse, clinical, social and treatment variables at baseline, five, and 10-year follow-up. Additionally, threatening and violent behavior was assessed at 10-year follow-up. A clinical epidemiological sample of first-episode psychosis patients (n=178) was studied.
During the 10-year follow-up period, 20% of subjects had been apprehended or incarcerated. At 10-year follow-up, 15% of subjects had exposed others to threats or violence during the year before assessment. Illegal drug use at baseline and five-year follow-up, and a longer duration of psychotic symptoms were found to be predictive of violent behavior during the year preceding the 10-year follow-up.
After treatment initiation, the overall prevalence of violence in psychotic patients drops gradually to rates close to those of the general population. However, persistent illicit drug abuse is a serious risk factor for violent behavior, even long after the start of treatment. Achieving remission early and reducing substance abuse may contribute to a lower long-term risk for violent behavior in FEP patients.

Abstract
Identifying patients at risk of poor outcome at an early stage of illness can aid in treatment planning. This study sought to create a best-fit statistical model of known baseline and early-course risk factors to predict time in psychosis during a ten-year follow-up period after a first psychotic episode.
Between 1997 and 2000, 301 patients with DSM-IV nonorganic, nonaffective first-episode psychosis were recruited consecutively from catchment area-based sectors in Norway and Denmark. Specialized mental health personnel evaluated patients at baseline, three months, and one, two, five, and ten years (N=186 at ten years). Time in psychosis was defined as time with scores =4 on any of the Positive and Negative Syndrome Scale items P1, P3, P5, P6, and G9. Evaluations were retrospective, based on clinical interviews and all available clinical information. During the first two years, patients were also evaluated by their clinicians at least biweekly. Baseline and early-course predictors of long-term course were identified with linear mixed-model analyses.
Four variables provided significant, additive predictions of longer time in psychosis during the ten-year follow-up: deterioration in premorbid social functioning, duration of untreated psychosis (DUP) of =26 weeks, core schizophrenia spectrum disorder, and no remission within three months.
First-episode psychosis patients should be followed carefully after the start of treatment. If symptoms do not remit within three months with adequate treatment, there is a considerable risk of a poor long-term outcome, particularly for patients with a deterioration in premorbid social functioning, a DUP of at least half a year, and a diagnosis within the core schizophrenia spectrum.
