Thombs Team Photo 2021 - Homepage.png

Welcome to the Thombs Research Team Website!

Dr. Brett Thombs is a Professor in the Faculty of Medicine at McGill University, a Senior Investigator at the Lady Davis Institute for Medical Research at the Jewish General Hospital, Chair of the Canadian Task Force on Preventive Health Care and Director of the Scleroderma Patient-centered Intervention Network (SPIN) and Director of the DEPRESsion Screening Data (DEPRESSD) Project.

Members of the Thombs Research Team work in three projects or areas: (1) SPIN, (2) the DEPRESSD Project, and (3) meta research and policy, which includes the Canadian Task Force on Preventive Health Care (CTFPHC), the development of an extension of the CONsolidated Standards of Reporting Trials (CONSORT) statement for trials conducted in cohorts and other routinely collected data, and other meta-research projects.

Each project group includes research coordinators, research assistants, postdoctoral fellows, graduate and undergraduate students who collaboratively work on various aspects of the projects. Check out the individual project sections to learn more about each project team and our current team members.

Congratulations to Yin Wu and the DEPRESSD team on their publication in Psychological Assessment!

| 2023/01/31

Dr. Wu and the team compared the accuracy of the 7-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) with the 14-item full scale (HADS-T) to screen for depression. In this study, 20,700 participants (2,285 major depression cases) from 98 studies were included. We found that sensitivity and specificity of the HADS-T were not superior to the HADS-D for detecting major depression. Thus, using the full 14-item HADS-T for depression screening would require additional time and patient burden without improving accuracy.

Congratulations to the SPIN team on receiving a CIHR grant!

| 2023/01/25

The SPIN team has been awarded a 1-year $20,000 Planning and Dissemination Grant-Institute Community Support for its project titled “Towards Understanding Pain Sources, Patterns, and Barriers to Effective Management in Systemic Sclerosis: A Patient-Researcher Partnership Musculoskeletal Health and Arthritis.” Thanks to team member Elsa-Lynn Nassar for her leadership on the proposal. This project will involve SPIN researchers and patient partners to jointly develop a tool to assess sources of pain in systemic sclerosis (SSc), pain management services, and barriers to improving pain management. Congrats to the SPIN team!

Congratulations to Marc on receiving the MUHC 2023 Studentship!
| 2023/01/17

We are excited to share that Marc Parsons (McGill PhD candidate in biostatistics and DEPRESSD team member) has been granted a McGill University Health Centre Research Institute (RI-MUHC) 2023 Studentship for his proposed thesis work entitled: Using flexible regression methods to analyse depression trajectories in an individual participant data meta-analysis of pregnant and postpartum women. This studentship was awarded based on the basis of academic performance, publications, research experience, training environment, and the merits of the proposed research project.

Congratulations to the SPIN team on receiving Arthritis Society of Canada Innovation Grant!
| 2022/11/28

The SPIN Team was awarded a $100,000 Arthritis Society of Canada Innovation Grant for its project titled “A Scleroderma Patient-centered Intervention Network patient-researcher partnership to understand pain sources, patterns, and barriers to effective management in systemic sclerosis”. Thanks to team member Elsa-Lynn Nassar for her work on the proposal. The project will involve a patient-researcher partnership to jointly develop a pain assessment tool for scleroderma and administer the final version of the tool to the SPIN cohort. This will provide improved techniques for pain assessment in scleroderma and improved understanding of the multi-faceted nature of scleroderma pain, which is critical for improving management. Congrats to the SPIN Team!

SPIN-SSLED Trial Results Published in Orphanet Journal of Rare Diseases!
| 2022/10/31

The SPIN Scleroderma Support group Leader Education (SPIN-SSLED) Program Trial results were published in Orphanet Journal of Rare Diseases. In the trial, 148 existing or candidate peer support group leaders were randomised to the 13-week videoconference-based program or to waitlist, and primary outcome data were provided by 146 (99%) participants. Satisfaction with the program was extremely high (30.3 out of possible 32 points), and participants attended an average of 11.4 out of 13 sessions. The program improved support group leader self-efficacy substantially, as well as leader volunteer satisfaction. The SPIN-SSLED Program continues to be offered by SPIN in collaboration with our patient organization partners. Link

Congratulations to Elsa on her publication in the International Journal of Methods in Psychiatric Research!| 2022/09/07

A meta-research review led by team member Elsa-Lynn Nassar and co-authored by other team members, including Brooke Levis, Marieke Neyer, and Danielle Rice, was recently published in the International Journal of Methods in Psychiatric Research. The team assessed the completeness and transparency of reporting of recently published depression screening accuracy studies. A total of 106 studies were included and assessed for consistency with the Standards for Reporting of Diagnostic Accuracy Studies (STARD) statement requirements. Overall, the team found that recently published depression screening accuracy studies are not optimally reported, with individual studies adequately reporting an average of approximately a third of the items in the STARD checklist. Of the 34 STARD items or sub-items, there were 8 items adequately reported, 7 partially reported, 11 inadequately reported, and 4 not applicable in ≥ 50% of included studies; the remaining 4 items had mixed reporting. The team concluded that there is a need for attention to more fulsome reporting of methodological conduct of these studies, mostly related to test methods, test results, and analysis aspects. In order to improve the quality of reporting in depression screening accuracy studies, the research community, journal editors, reviewers, and funders should endorse and implement adherence to STARD.

Congratulations to the DEPRESSD team on receiving a new CIHR funding!
| 2022/07/14

We are excited to share that the DEPRESSD team was awarded a 5-year funding (1.4 million) by CIHR for “The DEPRESsion Screening Data (DEPRESSD) Project: A Novel International Individual Participant Data Meta-analysis Collaboration to Advance Research on Depression Screening Tool Accuracy, Develop Statistical Methodology, and Conduct Meta-Research.” This grant will allow our team to update datasets for depression screening tools and conduct related studies in three categories: clinical, development and evaluation of Statistical Methods for IPDMA (Individual participant data meta-analysis) , and meta-research.

Congratulations to Tiffany and the COVID-19 LSR team on their publication in Scientific Reports!
| 2022/07/06

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 the SPIN team on receiving new CIHR funding!
| 2022/06/29

The SPIN Team was awarded a $20,000 CIHR Planning and Dissemination Grant and ranked very high for its proposal titled “Engaging Patients to Develop a Systemic Program of Patient Engagement in Musculoskeletal and Rare Disease Research: Putting Patients First”. The proposal was led by team member Elsa-Lynn Nassar, Dr. Brett Thombs, patient partner Maureen Sauvé, and Dr. Linda Kwakkenbos. This grant will support SPIN’s patient engagement work, which will involve engaging SPIN’s patient partners, scleroderma patient organization leaders, researchers, and clinicians to jointly develop an evidence-based framework for a patient engagement program. Congrats to the SPIN Team!
