The effectiveness of psychological interventions delivered by health professionals for adult cannabis use in community settings
Open AccessSabrina Giguère, Stéphane Potvin et al.ARTICLEFrontiers in Psychiatry2026
Evidence supporting the effectiveness of psychological interventions for problematic cannabis use remains limited. Findings should be interpreted with caution, highlight the need for further high-quality research focusing on clinically meaningful outcomes beyond consumption patterns, as well as on the development and rigorous evaluation of innovative interventions targeting cannabis-related harms
Beyond individual factors
Open AccessAudrey-Ann Journault, Alexe Bilodeau-Houle et al.ARTICLEJournal of School Psychology2025
This study explored the simultaneous role of selected individual, parental, and school factors in student's test anxiety. In 2019, both members of 339 Canadian parent-child dyads ( N = 626; 209 girls, 260 mothers, mostly White, child M age = 15.2) from 13 schools completed self-report validated scales at two time points (May/June 2019 and October/November 2019). Results from multilevel mixed-effects models revealed that negative stress mindsets, …
Web-enhanced return-to-work coordination for employees with common mental disorders
Open AccessMarc Corbière, Maud Mazaniello-Chézol et al.ARTICLEBMC Public Health2025
The findings suggest that incorporating PRATICA dr into RTW-C intervention can lead to substantial cost savings by facilitating coordination among stakeholders and guiding the RTW process with validated tools. Initiation of RTW-C intervention alongside PRATICA dr within the first month of absence is recommended for optimal health and work outcomes
The Association of Cortisol and Testosterone Interaction With Inpatient Violence
Open AccessYasmine Zerroug, Arianne Imbeault et al.ARTICLEAggressive Behavior2025References: 43
Psychiatric inpatient aggression is a concern as it poses a threat to safety of both patients and staff. While psychosocial and behavioral approaches are often put forward, the role of biological factors remains underexplored in a clinical context such as psychiatric hospitals. The dual‐hormone hypothesis (DHH) posits that low levels of cortisol combined with high levels of testosterone promote status‐seeking behaviors with some differences betwe…

Insomnie et risque suicidaire dans les troubles de la personnalité du groupe B
Open AccessMagali Tisseyre, Alexandre Hudon et al.ARTICLESanté mentale au Québec2023
Objectif Le taux de mortalité par suicide parmi les personnes souffrant d’un trouble de la personnalité du groupe B (TPB) se situe autour de 20 %. La haute prévalence de comorbidités anxiodépressives ainsi que l’abus de substances majorent ce risque. Selon des études récentes, l’insomnie persistante serait aussi un facteur de risque suicidaire dans ce groupe clinique. Les mécanismes expliquant cette association sont peu connus.

The Association of Childhood Maltreatment, Sex, and Hair Cortisol Concentrations With Trajectories of Depressive and Anxious Symptoms Among Adult Psychiatric Inpatients
Open AccessChristina Y Cantave, Isabelle Ouellet-Morin et al.ARTICLEPsychosomatic Medicine2022
OBJECTIVE: Depression and anxiety symptoms are commonly observed among clinical populations, especially among women and maltreated individuals. Few investigations have, however, assessed the existence of distinct symptoms trajectories among clinical populations and how these relate to childhood maltreatment, sex differences, and stress physiology indexed by hair cortisol concentrations (HCCs). The current study a) identified distinct depression a…
Comparing Childhood Characteristics of Adopted and Non-adopted Individuals Deceased by Suicide
Open AccessFabienne Ligier, Festus Body Lawson et al.ARTICLEFrontiers in Psychiatry2022
This study underlines the fact that adoptive families need to be supported throughout adoption. Health care professionals need specialized training on this matter, and the psychological challenges adopted individuals face need to be treated at the earliest juncture
Anxiety in the Classroom
Open AccessSandrine Charbonneau, Audrey‐ann Journault et al.ARTICLEInternational Journal of…2022
Many teens report experiencing anxiety in school, which can negatively impact their well-being. Considering that adolescents tend to adopt the same behaviors as their classmates with whom they spend, on average, 923 h every year, the current exploratory study (1) assessed whether an association exists between a student’s state anxiety score and his/her classmates’ average trait anxiety scores and (2) examined whether this association differed bet…
Peripheral Endogenous Cannabinoid Levels Are Increased in Schizophrenia Patients Evaluated in a Psychiatric Emergency Setting
Open AccessStéphane Potvin, Louiza Mahrouche et al.ARTICLEFrontiers in Psychiatry2020
The current results add to the growing body of evidence of endocannabinoid alterations in schizophrenia. The strong elevation of plasma anandamide levels in schizophrenia patients assessed in the psychiatric emergency setting suggests that anandamide and OEA area potential biomarkers of the psychological turmoil associated with this context

Trajectories of Dynamic Risk Factors as Predictors of Violence and Criminality in Patients Discharged From Mental Health Services
Open AccessMélissa Beaudoin, Stéphane Potvin et al.ARTICLEFrontiers in Psychiatry2019
Background: Individuals with severe mental illnesses are at greater risk of offenses and violence, though the relationship remains unclear due to the interplay of static and dynamic risk factors. Static factors have generally been emphasized, leaving little room for temporal changes in risk. Hence, this longitudinal study aims to identify subgroups of psychiatric populations at risk of violence and criminality by taking into account the dynamic c…
The Psychometric Properties of a Short UPPS-P Impulsive Behavior Scale Among Psychiatric Patients Evaluated in an Emergency Setting
Open AccessJules R Dugré, Charles‐Édouard Giguère et al.ARTICLEFrontiers in Psychiatry2019
Objective: Impulsivity is a multidimensional construct that has an important role for the understanding of diverse psychopathologies and problematic behaviors. The UPPS-P impulsive behavior scale, measuring five distinct facets of impulsivity, has been subject to several studies. No study has investigated the clinical utility of this questionnaire amongst an unstable psychiatric population. The aim of the current study is to examine the psychomet…
Persistency of Cannabis Use Predicts Violence following Acute Psychiatric Discharge
Open AccessJules R Dugré, Laura Dellazizzo et al.ARTICLEFrontiers in Psychiatry2017
These findings are particularly relevant as they suggest that the longer individuals report having used cannabis after a psychiatric discharge, the more likely they are of being violent in the following time waves. These results add to our understanding of the negative consequences of chronic cannabis use amid psychiatric patients
