[Joint study of seclusion, mechanical restraint and chemical restraint: Pilot study in three French psychiatric hospitals]. / Étudier conjointement l'isolement, la contention mécanique et la contention chimique : étude pilote dans trois établissements psychiatriques français.

Psychiatric wards that only exceptionally use isolation and mechanical restraint may be suspected of using "chemical restraint". However, in the case of these services, the hypothesis of a reduction in the general level of restraint can also be formulated. Prior to a comprehensive study to test these hypotheses, the current research aims to assess indicators which define high levels of the use of these measures and a relevant sample. The study was conducted in three facilities with 254 hospitalized patients over a week. Five per cent experienced isolation, 2% mechanical restraint, and 13% received high doses of medication (including "as needed" treatments). These figures are below literature data and national averages. Variances exist among centers, with one showing higher percentages for all three measures. While confirming the feasibility of studying these measures together, the study suggests the need for longer observations and continuous evaluation of prescription practices to better reflect yearly isolation and restraint trends. Future studies should involve more centers and include case studies for a nuanced understanding of administration practices in relation to prescriptions.

The clinician-administered PTSD Scale for DSM-5 (CAPS-5) structured interview for PTSD: A French language validation study.

The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is a structured interview that assesses the frequency and severity of each symptom of posttraumatic stress disorder (PTSD) in relation to a single traumatic stressor over a 1-month period, allowing the trained interviewer to infer a current or lifetime diagnosis congruent with the 5th Edition of the Diagnostic and Statistical Manual of the American Psychiatric Association. This study evaluated the psychometric properties of the original English language CAPS-5 translated to French. Participants (N = 168) were recruited in clinical settings of France, Lebanon, and Canada. The psychometric properties of the measure were found to be excellent, as good-to-strong interitem consistency was found (α = .90; ITC = .52; ICC = .30), while also finding strong convergent validity between the CAPS-5 total score and the severity score of a self-report PTSD measure (r = .82): the PCL-5. The test-retest reliability was excellent, with Cohen's κ = 1.00 and the intraclass coefficient (ICC) = .95. However, no latent factor structure model was deemed a strong fit to the data. Overall, the reliability and validity of the French CAPS-5 and are consistent with those of the original CAPS-5. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Understanding the link between childhood trauma and schizophrenia: A systematic review of neuroimaging studies.

Increasing evidence suggests that childhood trauma (CT) is a major risk factor for schizophrenia but the underpinning mechanisms of their association remain unclear. Our aim is to review the literature on the association between CT and brain imaging measurements in adult schizophrenia subjects. We conducted a systematic review of the existing neuroimaging literature on CT and schizophrenia. We reviewed studies considering adult subjects with schizophrenia, schizoaffective disorder or first episode schizophrenia. A total of 15 studies were included. The most replicated result was the association in schizophrenia patients between CT and decreased total cerebral grey matter, particularly in the prefrontal cortex. In addition, studies suggest a different sensitivity to early stressors between schizophrenia subjects, their sibling and healthy unrelated subjects. In schizophrenia, CT is associated with alterations of white matter integrity in the inferior and superior longitudinal fasciculus, the inferior fronto-occipital fasciculus and the forceps major. Functional connectivity studies suggest an association between CT and a network including the amygdala, the anterior cingulate cortex, the precuneus/posterior cingulate cortex region and the temporo-parietal junction.
