We are excited to share that the COVID-19 LSR team was awarded a 2-year funding ($233,000) by CIHR for “Recovering from the COVID-19 Pandemic, Informing Future Public Health Crises, and Building Global Evidence Base for Mental Health Research: A Systematic Review of COVID-19 related Mental Health.” This grant will allow our team to integrate new evidence into our comparison prior to and during COVID-19, evaluate mental health symptom trajectories across the pandemic, and conduct a meta-research review of COVID-19 mental health research to identify strengths and weaknesses in planning for ongoing mental health surveillance and future disaster preparedness.

A meta-analysis of primary studies employing the Geriatric Depression Scale (GDS-15) led by Marc Parsons and supported by DEPRESSD team members was published in Scientific Reports. Many studies use the GDS-15 to estimate depression prevalence. The team compared prevalence based on the GDS-15 to a gold-standard diagnostic test of depression. We found that the most used GDS-15 cutoff overestimated depression prevalence substantially and that the cutoff that most closely matched true prevalence provided estimates which were too heterogeneous to be useful in practice.

An individual-patient data meta-analysis led by Nadia González Domínguez was recently published in the Journal of Clinical Epidemiology. The study aimed to estimate the minimal detectable difference of the 15-item geriatric depression scale (GDS-15). The team found that this estimate was around 3.81 points for the highest confidence level used, and was influenced by the proportion of people with major depression in a given study. Read more here.

A cross-sectional SPIN Cohort study led by Afra Alkan was recently accepted for publication in Arthritis Care & Research. The study aimed to assess minimal detectable changes (MDCs) of the Health Assessment Questionnaire-Disability Index, Patient Reported Outcomes Measurement Information System-29 Profile version 2.0 domains, and Patient Health Questionnaire-8 in Systemic Sclerosis, as well as compare MDC estimates by age, sex, and SSc subtype. The team found that MDC95 estimates were not materially different across subgroups. For more information on this study, click here.

Dr. Thombs was quoted in a Washington Post article on menopause and depression. Similar to our team’s work, the article scrutinizes evidence and concludes that the menopause depression link is not likely much greater than for other health conditions that people experience.

Dr. Yin Wu and the team reviewed data contribution to the four depression screening tool accuracy individual participant data meta-analyses (IPDMAs). We found that 65% of 456 eligible studies contributed data overall; data contribution was associated with multiple characteristics of primary studies. Over 80% of 161 non-contributions were because authors were unreachable or data were unavailable. This was the largest study to investigate data contribution to IPDMAs that has examined characteristics of eligible studies and the first in the field of diagnostic test accuracy, which may support future research to promote data contribution to IPDMAs.

A living systematic review on COVID-19 mental health changes, led by Sheryl and co-authored by other LSR members, has been published in the BMJ. This review evaluated longitudinal studies that compared mental health outcomes prior to the pandemic and during COVID-19. The team analyzed data from 134 cohorts of people from 31 countries. They found that there are no or minimal changes in mental health among the general population and 11 subgroups (e.g., age groups, sex or gender, pre-existing medical or mental health conditions). One exception is among women for whom there were consistent negative small changes across outcome domains. The results suggest that mental health in COVID-19 is more nuanced than previously assumed and that this is largely a story of resilience.

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.
