Results of the search for personality disorder screening tools: clinical implications.

Objective: To examine the characteristics, validity, posttest probabilities, and screening capabilities of 8 different instruments used to predict personality disorders.

Method: Screening instruments were examined in 3 prospective, observational, test-development studies in 3 random samples of Dutch psychiatric outpatients, using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) as the "gold standard." The studies were performed from March 2004 to March 2005 (study 1: N = 195, mean age = 32.

Quick Personality Assessment Schedule (PAS-Q): validation of a brief screening test for personality disorders in a population of psychiatric outpatients.

Objective: The internal consistency, test-retest reliability, and validity of the Quick Personality Assessment Schedule (PAS-Q), as a screening instrument for personality disorders were studied in a random sample of 195 Dutch psychiatric outpatients, using the SCID-II as a gold standard.

Method: All patients were interviewed with the PAS-Q. With an interval of 1 to 2 weeks, they were interviewed with the SCID-II.

Perceiving emotions from bodily expressions and multisensory integration of emotion cues in schizophrenia.

Most studies investigating emotion recognition in schizophrenia have focused on facial expressions and neglected bodily and vocal expressions. Furthermore, little is known about affective multisensory integration in schizophrenia. In the first experiment, the authors investigated recognition of static, face-blurred, whole-body expressions (instrumental, angry, fearful, and sad) with a two-alternative, forced-choice, simultaneous matching task in a sample of schizophrenia patients, nonschizophrenic psychotic patients, and matched controls.

Diagnostic efficiency among psychiatric outpatients of a self-report version of a subset of screen items of the Structured Clinical Interview for DSM-IV-TR Personality Disorders (SCID-II).

This article describes the identification of a 10-item set of the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) items, which proved to be effective as a self-report assessment instrument in screening personality disorders. The item selection was based on the retrospective analyses of 495 SCID-II interviews. The psychometric properties were studied in a prospective validation study in a random sample of Dutch adult psychiatric outpatients, using the SCID-II interview as the gold standard.

Internal and external validity of attention-deficit hyperactivity disorder in a population-based sample of adults.

Background: Follow-up studies of childhood ADHD have shown persistence of the disorder into adulthood, but no epidemiological data are yet available.

Method: ADHD DSM-IV symptoms were obtained by self-report in an adult population-based sample of 1813 adults (aged 18-75 years), that was drawn from an automated general practitioner system used in Nijmegen, The Netherlands. The structure of ADHD symptoms was analysed by means of confirmatory factor analyses.

Association between antidepressant drug use and hyponatraemia: a case-control study.

Aims: To estimate the risk of, and risk factors for, hyponatraemia associated with the use of selective serotonin reuptake inhibitors (SSRIs) compared with the use of other antidepressant drugs.

Methods: A case-control study of psychiatric in- and out-patients on antidepressant drugs performed in the mid-southern part of The Netherlands over a 2 year period. Cases (n=29) were all using antidepressant drugs with a serum sodium concentration of < or = 130 mmol l(-1) while controls (n=78) were patients on antidepressants with a normal sodium concentration (136-144 mmol l(-1)).
