Lab name: Impact of traumatic stress on mental health
Dr. Brunet studies the impact of traumatic stress on mental health. His main focus has been on characterizing the risk factors and developing effective treatments for Posttraumatic stress disorder (PTSD). He is also interested in the epidemiology, the neurobiology of PTSD, as well as in the uses of Internet for research/intervention purposes.
In 2001, Alain Brunet developed the first instrument designed to assess the recalled amount of distress experienced at the time of a traumatic event. This measure has been used by dozens of teams across the world and has been translated into twelve languages.
A major interest in Dr. Brunet’s research stems from a breakthrough that he and colleagues from McGill and Harvard University made when they used the common blood pressure drug, propranolol, to treat PTSD: when individuals recall their traumatic event under propranolol, the emotional strenght of the memory is subsequently and durably reduced, thereby leading to a PTSD symptom reduction.

However, a limited number of studies have examined its effects on mental health workers, a population at increased risk for vicarious traumatization.nnMETHODS: A mediation model was tested using longitudinal self-report data (N=1597). The association among occupation, severity of trauma-related and stressor-related (TSR) symptoms during the first wave of the COVID-19 pandemic, and self-efficacy was explored.nnRESULTS: Mental health workers reported greater self-efficacy than other survey participants (health care workers, general population) (unstandardized β=1.53, P<0.001), and greater self-efficacy was associated with lower TSR symptoms (-0.09, P<0.001). Hence, mental health workers reported lower TSR symptoms through both direct (-0.80, P=0.005) and indirect associations (-0.94, P<0.001), with higher self-efficacy compared with other survey participants.nnCONCLUSIONS: Despite being at greater risk for vicarious traumatization, mental health workers fared well during the first wave of COVID-19. Increasing self-efficacy in high-risk populations in the context of stressful/traumatic events may have some value, an avenue requiring further investigation.},

Accumulating evidence suggests shared neurobiological mechanisms. Trauma-focused interventions targeting maladaptive memory processes may therefore represent a relevant therapeutic approach in this population. : To evaluate the feasibility, tolerability, and preliminary clinical associations of a brief reconsolidation-based therapy in women with comorbid FMS and PTSD. : This multicenter pilot study included adult women diagnosed with FMS and PTSD who underwent six sessions of reconsolidation therapy combining traumatic memory reactivation with propranolol administration. Clinical outcomes were assessed at baseline and at 3-month follow-up using the Fibromyalgia Impact Questionnaire (FIQ), the Impact of Event Scale-Revised (IES-R), the Montgomery-Åsberg Depression Rating Scale (MADRS), the Beck Depression Inventory (BDI), the Rosenberg Self-Esteem Scale (RSES), and the SF-36. Changes over time were analyzed using paired statistical tests and linear mixed-effects models. : Fourteen participants completed the intervention and follow-up assessments. The intervention was feasible and well tolerated. Changes over time were observed in fibromyalgia-related quality of life (FIQ scores), PTSD symptom severity (IES-R), and depressive symptoms (MADRS, BDI), as well as in selected SF-36 domains, including vitality, social functioning, and mental health. A progressive decrease in IES-R scores was observed across treatment sessions. : This pilot study suggests that reconsolidation-based therapy is feasible in women with comorbid FMS and PTSD and was associated with changes in PTSD symptoms and fibromyalgia-related functional impact. Given the exploratory design and absence of a control group, these findings should be interpreted cautiously and warrant confirmation in larger, controlled trials.},

Given the barriers to traditional services, remote and online technologies are increasingly used in treating TSRD.nnAIMS: This mixed-methods systematic review aimed to identify remote technologies and assessed their feasibility and acceptability in treating adults with post-traumatic stress disorder (PTSD), acute stress disorder and adjustment disorder (AjD).nnMETHOD: The databases MEDLINE, CINAHL, Embase, PsycInfo, PubMed and the Cochrane Library were screened to identify studies investigating the feasibility and acceptability of remote interventions for PTSD, acute stress disorder and AjD in adults. Studies that obtained poor-quality ratings on critical appraisal tools were excluded. Results were synthesised using a narrative review approach.nnRESULTS: In total, there were 74 studies evaluating 27 remote interventions for TSRD: online interventions ( = 47, 63.51%), mobile applications ( = 17, 22.97%), video conferencing ( = 9, 12.16%) and message-based systems = 1, 1.35%). Findings from the review showed higher feasibility and acceptability for interventions with an interactive clinician-patient component. Among self-directed interventions, only two applications and eight online interventions provided a clinician component. Most studies targeted PTSD, with few targeting other diagnoses.nnCONCLUSIONS: Recommendations related to remote interventions for TSRDs should be broadened to include AjD and other underrepresented diagnoses, and tailored to individual patients' profiles, including their ability to sustain engagement and clinical needs, using a stepped-care approach.},

Emotional Resilience Skills Training (ERST) is a cognitive behavioural training program for PSP based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (i.e. Unified Protocol). The current study was designed to assess whether ERST is associated with reduced putative risk factors for mental disorders and increased individual resilience. The PSP-PTSI Study used a longitudinal prospective sequential experimental cohort design that engaged each participant for approximately 16 months. PSP from diverse sectors (i.e. firefighters, municipal police, paramedics, public safety communicators) completed self-report measures of several putative risk variables (i.e. anxiety sensitivity, fear of negative evaluation, pain anxiety, illness and injury sensitivity, intolerance of uncertainty, state anger) and resilience at three time points: pre-training ( = 191), post-training ( = 103), and 1-year follow-up ( = 41). Participant scores were statistically compared across time points. Participants reported statistically significantly lower scores on all putative risk variables except pain anxiety, and statistically significantly higher resilience from pre- to post-training. Changes were sustained at 1-year follow-up. The results indicate that ERST is associated with reductions in several putative risk variables and improvement in resilience among PSP.},

The current study assessed PPTE exposures during the CTP and examined associations with mental disorders among RCMP cadets. Participants were cadets (n = 449, 24.7% women) from the larger RCMP Longitudinal Study who self-reported critical incidents, PPTE exposures, and mental health disorder symptoms at pretraining and predeployment. Most participants reported no exposures to a PPTE (n = 374, 83.3%) during the CTP. Participants who reported any PPTE exposure (n = 75, 16.7%; i.e., direct or indirect) most commonly reported serious transport accidents, physical assault, and sudden accidental death. The most common direct PPTEs (i.e., "happened to me") during the CTP were physical assault (n = 13), other unwanted or uncomfortable sexual experience (n = 11), and serious transportation accident (n = 8). The total number of PPTE types reported at predeployment was associated with increased odds of screening positive for any mental health disorder, aOR = 1.22, 95% CI [1.01, 1.49], p = .049, and positively associated with mental health disorder symptoms, ps < .001. These results provide the first assessment of PPTE exposure among RCMP cadets during the CTP, indicating that 16.7% of cadets experience PPTEs directly or indirectly. The PPTEs reported by cadets may help inform additional opportunities to further increase safety during training.},

This review summarizes the different theories and models of mental illness and health pertaining to the breast cancer experience and proposes an integrative phasic model applicable to the breast cancer trajectory. Five databases were searched for studies related to breast cancer mental health and illness theories and models. The PRISMA checklist form was used to extract the essential information from the included studies. Eleven theories and models on the experience of breast cancer were found. The integrative model based on these theories and models illustrates that the breast cancer experience is conceptualized as a trajectory with seven landmark '', each associated with a pathogenic '' leading to six possible '', 1) psychological distress with anxious features, 2) psychological distress with depressive features, 3) non-specific distress 4) psychological distress with trauma-related features 5) low health-related quality of life, and 6) fear of recurrence. The Breast Cancer Psychological Integrative Phasic Model is supported by a simple clinical tool (BreastCancerPsych - Integrative Clinical Tool) that serves as a valuable resource throughout the care trajectory. These integrative phasic model and clinical tool are designed to help mental health clinicians formulate treatments that are tailored to the needs of their patients, especially for trajectories that are not marked by resilience.},

Databases were searched in October 2022 and updated in February 2023 to find empirical studies reporting psychosocial intervention targeting body image efficacy. The results from 24 studies show many similarities and differences between the definitions (e.g. characteristics) and questionnaires (e.g. Cronbach's alpha coefficient) used to evaluate this concept. Most definitions include thoughts, feelings, and behaviors related to body image. Finally, the psychosocial implications are discussed.

Mental health challenges for military and paramilitary populations have historically been attributed to insufficient recruit screening; however, cadet mental health when starting the Cadet Training Program (CTP) was unknown. Our objective was to estimate RCMP Cadet mental health when starting the CTP and test for sociodemographic differences.nnMETHOD: Cadets starting the CTP completed a survey assessing self-reported mental health symptoms ( = 772, 72.0% male) and a clinical interview ( = 736, 74.4% male) with a clinician or supervised trainee using the Mini-International Neuropsychiatric Interview to assess current and past mental health.nnRESULTS: The percentage of participants screening positive for one or more current mental disorders based on self-reported symptoms (15.0%) was higher than the diagnostic prevalence for the general population (10.1%); however, based on clinical interviews, participants were less likely to screen positive for any current mental disorder (6.3%) than the general population. Participants were also less likely to screen positive for any past mental disorder based on self-report (3.9%) and clinical interviews (12.5%) than the general population (33.1%). Females were more likely to score higher than males (all s<.01; Cohen's s .23 to .32) on several self-report mental disorder symptom measures.nnCONCLUSIONS: The current results are the first to describe RCMP cadet mental health when starting the CTP. The data evidenced a lower prevalence of anxiety, depressive, and trauma-related mental disorders than the general population based on clinical interviews, contrasting notions that more rigorous mental health screening would reduce the high prevalence of mental disorders among serving RCMP. Instead, protecting RCMP mental health may require ongoing efforts to mitigate operational and organizational stressors.},

Although sociodemographic factors contributing to peritraumatic distress have been previously investigated, no research has examined the nature and severity of peritraumatic distress reactions in a non-clinical, community sample as a function of age. An international sample of 5621 adult participants were grouped according the World Health Organization's age stratification protocol. Mean scores and item endorsement on the PDI were compared across groups with respect to their worst experience of the COVID-19 pandemic. A significant between-group difference was found, F(55,615) = 30.74, p < 0.001, n = 0.027 whereby participants aged 18-39 years old reported the highest levels of peritraumatic distress. This group also endorsed a higher proportion of items on the PDI's two main factors (emotional distress and physical reactions), and were more likely to endorse feelings of helplessness, than older participants. It appears that severity of peritraumatic distress during the pandemic has affected younger people the most. Results are discussed in light of clinical implications.},

The estimates of suicidal behaviours appear lower than the general population and lower than reports from serving RCMP. Higher prevalence estimates of suicidal behaviours reported by serving RCMP, relative to lower estimates among cadets starting the CTP in the current study, may be related to age, cumulative experiences or protracted exposures to operational and organizational stressors, rather than insufficient screening of recruits.},

abstract = {OBJECTIVE: Royal Canadian Mounted Police (RCMP) report extremely frequent and varied exposures to potentially psychologically traumatic events (PPTEs). While occupational exposures to PPTEs may be one explanation for the symptoms of mental disorders prevalent among serving RCMP, exposures occurring prior to service may also play a role. The objective of the current study was to provide estimates of lifetime PPTE exposures among RCMP cadets in training and assess for associations with mental disorders or sociodemographic variables.nnMETHODS: RCMP cadets ( = 772; 72.0% male) beginning the Cadet Training Program (CTP) completed a survey assessing self-reported PPTE exposures as measured by the Life Events Checklist for the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition-Extended. Binomial tests were conducted to compare the current results to previously collected data from the general population, a diverse sample of public safety personnel (PSP) and serving RCMP.nnRESULTS: Cadets reported statistically significantly fewer PPTE exposures for all PPTE types than serving RCMP (all s < 0.001) and PSP (all s < 0.001) but more PPTE exposures for all PPTE types than the general population (all s < 0.001). Cadets also endorsed fewer PPTE types (6.00 ± 4.47) than serving RCMP (11.64 ± 3.40; < 0.001) and other PSP (11.08 ± 3.23) but more types than the general population (2.31 ± 2.33; < 0.001). Participants who reported being exposed to any PPTE type reported the exposures occurred 1-5 times (29.1% of participants), 6-10 times (18.3%) or 10 + times (43.1%) before starting the CTP. Several PPTE types were associated with positive screens for one or more mental disorders. There were associations between PPTE types and increased odds of screening positive for post-traumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD) and social anxiety disorder (SAD) (all < 0.05). Serious transport accident (11.1%), physical assault (9.5%) and sudden accidental death (8.4%) were the PPTEs most identified as the worst event, and all were associated with positive screens for one or more mental disorders.nnCONCLUSION: The current results provide the first information describing PPTE histories of cadets, evidencing exposure frequencies and types much higher than the general population. PPTE exposures may have contributed to the cadet's vocational choices. The current results support the growing evidence that PPTEs can be associated with diverse mental disorders; however, the results also suggest cadets may be uncommonly resilient, based on how few screened positive for mental disorders, despite reporting higher frequencies of PPTE exposures prior to CTP than the general population.},

abstract = {BACKGROUND: Royal Canadian Mounted Police (RCMP) officers experience an elevated risk for mental health disorders due to inherent work-related exposures to potentially psychologically traumatic events and occupational stressors. RCMP officers also report high levels of stigma and low levels of intentions to seek mental health services. In contrast, very little is known about the levels of mental health knowledge and stigma of RCMP cadets starting the Cadet Training Program (CTP). The current study was designed to: (1) obtain baseline levels of mental health knowledge, stigma against peers in the workplace, and service use intentions in RCMP cadets; (2) determine the relationship among mental health knowledge, stigma against peers in the workplace, and service use intentions among RCMP cadets; (3) examine differences across sociodemographic characteristics; and (4) compare cadets to a sample of previously surveyed serving RCMP.nnMETHODS: Participants were RCMP cadets ( = 772) starting the 26-week CTP. Cadets completed questionnaires assessing mental health knowledge, stigma against coworkers with mental health challenges, and mental health service use intentions.nnRESULTS: RCMP cadets reported statistically significantly lower levels of mental health knowledge ( = 0.233) and stigma ( = 0.127), and higher service use intentions ( = 0.148) than serving RCMP (all s < 0.001). Female cadets reported statistically significantly higher scores on mental health knowledge and service use and lower scores on stigma compared to male cadets. Mental health knowledge and service use intentions were statistically significantly positively associated. For the total sample, stigma was inversely statistically significantly associated with mental health knowledge and service use intentions.nnCONCLUSION: The current results indicate that higher levels of mental health knowledge were associated with lower stigma and higher intention to use professional mental health services. Differences between cadets and serving RCMP highlight the need for regular ongoing training starting from the CTP, designed to reduce stigma and increase mental health knowledge. Differences between male and female cadets suggest differential barriers to help-seeking behaviors. The current results provide a baseline to monitor cadet mental health knowledge and service use intentions and stigma as they progress throughout their careers.},

abstract = {INTRODUCTION: Royal Canadian Mounted Police (RCMP) officers self-report high levels of mental health disorder symptoms, such as alcohol use disorder, generalized anxiety disorder, major depressive disorder, panic disorder, and posttraumatic stress disorder. Participation in regular mental health monitoring has been associated with improved mental health disorder symptom reporting and may provide an accessible tool to support RCMP mental health. The current study assessed relationships between self-reported mental health disorder symptoms and the completion of daily surveys (i.e., daily mental health disorder symptom monitoring) by RCMP cadets during the Cadet Training Program (CTP).nnMETHODS: Participants were RCMP cadets ( = 394; 76.1% men) in the Standard Training Program who completed the 26-week CTP and daily self-monitoring surveys, as well as full mental health assessments at pre-training (i.e., starting the CTP) and pre-deployment (i.e., ~2 weeks prior to deployment to the field). Symptoms of alcohol use disorder, generalized anxiety disorder, major depressive disorder, panic disorder, and posttraumatic stress disorder were assessed. Changes in mental health disorder symptom reporting from pre-training to pre-deployment were calculated. Spearman's rank correlations were estimated for number of daily surveys completed and change in mental health disorder symptom scores between pre-training and pre-deployment.nnRESULTS: There were statistically significant inverse relationships between number of daily surveys completed and number of mental health disorder symptoms reported; specifically, cadets who completed more daily surveys during CTP reported fewer symptoms of alcohol use disorder, generalized anxiety disorder, major depressive disorder, panic disorder, and posttraumatic stress disorder.nnCONCLUSION: An inverse correlation between number of daily surveys completed and mental health disorder symptom scores indicated that participation in daily mental health monitoring was associated with improvements in self-reported mental health disorder symptoms between pre-training and pre-deployment. Regular self-monitoring of mental health disorder symptoms may help to mitigate mental health challenges among RCMP cadets and officers.},

abstract = {BACKGROUND: Public safety personnel (PSP; e.g., border services personnel, correctional workers, firefighters, paramedics, police, public safety communicators) are frequently exposed to potentially psychologically traumatic events. Such events contribute to substantial and growing challenges from posttraumatic stress injuries (PTSIs), including but not limited to posttraumatic stress disorder.nnMETHODS: The current protocol paper describes the PSP PTSI Study (i.e., design, measures, materials, hypotheses, planned analyses, expected implications, and limitations), which was originally designed to evaluate an evidence-informed, proactive system of mental health assessment and training among Royal Canadian Mounted Police for delivery among diverse PSP (i.e., firefighters, municipal police, paramedics, public safety communicators). Specifically, the PSP PTSI Study will: (1) adapt, implement, and assess the impact of a system for ongoing (i.e., annual, monthly, daily) evidence-based assessments; (2) evaluate associations between demographic variables and PTSI; (3) longitudinally assess individual differences associated with PTSI; and, (4) assess the impact of providing diverse PSP with a tailored version of the Emotional Resilience Skills Training originally developed for the Royal Canadian Mounted Police in mitigating PTSIs based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders. Participants are assessed pre- and post-training, and then at a follow-up 1-year after training. The assessments include clinical interviews, self-report surveys including brief daily and monthly assessments, and daily biometric data. The current protocol paper also describes participant recruitment and developments to date.nnDISCUSSION: The PSP PTSI Study is an opportunity to implement, test, and improve a set of evidence-based tools and training as part of an evidence-informed solution to protect PSP mental health. The current protocol paper provides details to inform and support translation of the PSP PTSI Study results as well as informing and supporting replication efforts by other researchers.nnTRIAL REGISTRATION: Hypotheses Registration: aspredicted.org, #90136.

abstract = {OBJECTIVES: In a sustained relationship, romantic betrayal is a catastrophic event that can precipitate an adjustment disorder (AD). Surprisingly, there exists no empirically validated treatment for AD, despite its high prevalence in clinical practice. Considering the promise of memory reactivation under propranolol (i.e., reconsolidation interference) for treating posttraumatic stress disorder, we sought to extend this finding to AD, given that in both disorders, symptoms stem from an identified stressor.nnMETHOD: A single-blind interrupted time series design was used to examine the efficacy of memory reactivation under propranolol to alleviate symptoms of AD. After being placed on a 4-week waitlist, sixty-one participants received 5 weekly 25-min treatments during which they recalled the betrayal event, 1 h after having orally ingested the beta-blocker propranolol.nnRESULTS: Segmented regression analyses on the intent-to-treat sample revealed that AD symptoms significantly decreased during the treatment phase (pre/post Cohen's d = 1.44), compared to the waitlist phase (d = 0.01). Significant pre/post reductions in anxio-depressive symptomatology were also found. Improvement was maintained at the 4-month follow-up on all outcomes.nnCONCLUSION: Memory reactivation under propranolol shows promise in reducing symptoms of AD. This study provides the theoretical framework and necessary effect sizes to inform larger, double-blind, placebo-controlled clinical trials.},
