Meet our team

DEPRESSD is an international collaborative project involving experts in health policy, psychiatry and statistics as well as investigators who have collected depression screening data. Our mission is to synthesize the global depression screening data in order to develop and apply rigourous methods on assessing depression screening tool accuracy that minimize bias and provide evidence to inform research and policy to improve mental health care. The project builds a database for shared usage and also provides a unique platform for trainee development, including skills in evidence synthesis and statistical modelling.

We are happy to share that the COVID-19 LSR team's paper on sex and gender differences in mental health symptom changes from pre-pandemic to early-pandemic is now published in Scientific Reports. This paper, led by Tiffany, identified 12 studies that reported dichotomized sex or gender data both prior to and during the COVID-19 pandemic. Assessed outcomes included anxiety symptoms, depression symptoms, general mental health, and stress. The paper concludes that mental health outcomes did not differ or were worse by small amounts among females/women compared to males/men during early COVID-19. Mental health changes should continue to be monitored longitudinally in COVID-19 taking into consideration sex and gender, as well as other population subgroups.

Congratulations to Elsa on receiving the McGill Post-Graduate Student Society Travel Award!



Team member Elsa-Lynn Nassar was recently awarded the McGill Post-Graduate Student Society Travel Award to attend the Canadian Psychological Association's annual conference being held this June in Calgary. Elsa will be presenting results from her master's thesis work on the methodological quality and reporting transparency of depression screening accuracy studies through three posters and an oral presentation. Congratulations, Elsa!

Congratulations to Amina and COVID LSR team on their publication in General Hospital Psychiatry!



We are excited to share that the COVID-19 LSR team's paper, led by Amina, on effects of mental health interventions among people hospitalized with COVID-19 , is now published in General hospital Psychiatry. This paper identified 47 randomized controlled trials from 3 countries, of which 21 tested the effects of psychological interventions, 5 physical and breathing exercises, and 21 a combination of interventions. It concludes that due to poor quality reporting there is insufficient evidence to make clinical recommendations based on included trials. Read more about the paper here.

Congratulations to the DEPRESSD Team on receiving new funding from CRCC and SSHRC!



We are thrilled to share that our DEPRESSD team was awarded a 1-year grant ($237,861) of New Frontiers in Research Fund. 2021 Innovative Approaches to Research in the Pandemic Context by Canada Research Coordinating Committee (CRCC) and the Social Sciences and Humanities Research Council (SSHRC) for our project “Comparison of depression research diagnoses and symptom scores obtained via conventional in-person and alternative methodologies”. This funding will allow the team to robustly evaluate how data collection methods, especially alternative methods increasingly used in COVID-19 may influence sensitive mental health assessments. Thanks to Yin for leading this!

Elsa's meta-research review is now published in the International Journal of Methods in Psychiatric Research!



Another review, led by team member Elsa-Lynn Nassar and co-authored by team members Dr. Brooke Levis, Marieke Neyer, and Danielle Rice, is published in the International Journal of Methods in Psychiatric Research. The team examined 106 primary studies on the accuracy of depression screening tools. The team found that only 11% described a viable sample size calculation and 34% provided reasonably accurate confidence intervals (CIs). Overall, the number of included individuals in most studies was too small to generate reasonably precise accuracy estimates; of 103 studies where 95% CIs were provided or could be calculated, only 7% had sensitivity CI widths of ≤10%, whereas 58 (56%) had widths of ≥21%. The team recommends that future studies of the diagnostic accuracy of depression screening tools should conduct precision-based a priori sample size calculations to either attain desired precision levels or to understand limitations prior to initiating a study.

Congratulations to Dr. Yin Wu for receiving the McGill MedStar Award!



We are excited to share that Dr. Yin Wu (DEPRESSD’s postdoctoral research fellow) has earned the McGill Medstar Award for Trainees for her publication in BMJ entitled: Accuracy of the Hospital Anxiety and Depression Scale Depression Subscale (HADS-D) to screen for major depression: systematic review and individual participant data meta-analysis, in recognition of the excellent research carried out in the Faculty of Medicine and Health Sciences at McGill University. The winning papers were selected to demonstrate excellence at all levels and to represent all disciplines of our training programs in the Faculty of Medicine and Health Sciences.

Congratulations to Olivia and the COVID-19 LSR team on their publication in the Canadian Journal of Psychiatry!



We are happy to share that the COVID-19 LSR team's paper on the effects of COVID-19 mental health interventions among children, adolescents, and adultsis now published in the Canadian Journal of Psychiatry. This paper, led by Olivia Bonardi, included randomised-controlled trials of interventions to address COVID-19 mental health challenges among people not hospitalised or quarantined due to COVID-19 infection. It identified 9 eligible trials, including 3 well-conducted, well-reported trials that tested interventions designed specifically for COVID-19 mental health challenges, plus 6 other trials with high risk of bias and reporting concerns, all of which tested standard interventions (e.g., individual or group therapy, expressive writing, mindfulness recordings) minimally adapted or not specifically adapted for COVID-19. The paper concluded that interventions that adapt evidence-based strategies for feasible delivery may be effective to address mental health in COVID-19. More well-conducted trials, including for children and adolescents, are needed. Read more about the publication here.

Congratulations to Diana et al. on their publication in the Clinical and Experimental Rheumatology!



We are excited to share that Diana et al.’s Letter to Editors: The Hospital Anxiety and

Depression Scale in patients with systemic sclerosis: a psychometric and factor analysis in a monocentric cohort, is now published in the Clinical and Experimental Rheumatology. The letter describes that mental health symptom questionnaires like the HADS are not intended nor calibrated to estimate prevalence; in most cases, they tend to overestimate the true prevalence of psychiatric disorders, often dramatically. It also discusses the evidence that would be needed to recommend mental health screening, which is labour intensive and can lead to unnecessary harms, like all screening programs. Read the letter here.

Meta-research study led by Elsa-Lynn Nassar is accepted for publication in General Hospital Psychiatry!



A meta-research study led by Elsa-Lynn Nassar (MSc Trainee) and co-authored by other team members, including Dr. Brooke Levis (Research Associate) and Danielle Rice (PhD Candidate), was recently accepted for publication in General Hospital Psychiatry. The aims of the study were to assess (1) the proportion of recently published studies of depression screening accuracy that appropriately excluded individuals with a confirmed depression diagnosis or who were already undergoing treatment and (2) whether this has improved since the last review of studies published in 2013-2015. A total of 106 primary studies were identified and assessed. Eighteen of 106 (17%) studies appropriately excluded already diagnosed or treated individuals, representing an 11% improvement since the last review. The proportion of depression screening accuracy studies that appropriately exclude individuals already known to have depression remains low. This may significantly bias research findings intended to inform clinical practice, where known depression cases are not screened. To learn more about the study, click here!

Congratulations to the COVID-19 Living Systematic Review (LSR) Team on receiving new CIHR funding!



We are excited to share that our LSR team was awarded a two-year grant ($368,998) by CIHR’s Addressing the Wider Health Impacts of COVID-19 program for conducting our project “Loneliness Among Older Adults in COVID-19: A Living Systematic Review of Changes in Loneliness from Pre-COVID-19, Association with Mental Health Outcomes, and Effects of Interventions.” This funding will allow the team to continue to update its synthesis of evidence on mental health in COVID-19 and to specifically evaluate changes in loneliness and the effectiveness of interventions to reduce or prevent loneliness in older adults during COVID-19.
