Eligible intervention studies include randomized and non-randomized controlled trials of the effects of any intervention designed to im-prove any aspect of mental health during the COVID-19 pandemic. Only studies initiated after China’s initial declaration to the WHO on December 31, 2019, will be eligible. Eligible trials must target mental health, and mental health must be the primary trial outcome if a primary outcome is stated. Eligible interventions must be: 1) done to improve mental health with people with COVID-19; or 2) designed to specifically target COVID-19 related mental health concerns in people not identified as having COVID-19; interventions in this group that are not described as addressing mental health symptoms from COVID-19 or that are not tailored to address COVID-19 challenges will be excluded.
Please note that we have identified 55 non-randomized intervention trials. Because of small-scale population, poor reporting, and risk of bias concerns, we removed them from the current tables.
About Eligible Registered Trials
We have identified 83 registrations for trials that appear to be eligible once completed. Of the 83 trial registrations, 31 target the general population, 17 target medical staff, 2 target patients infected with COVID-19, 12 target people with pre-existing mental health conditions, 6 target people with pre-existing medical conditions, 1 targets university students, 2 target close contacts of COVID-19 patients, 1 targets US veterans, and 1 targets police personnel.
Registered trials are from Australia (N = 7), Brazil (N=3), Belgium (N=2), Canada (N = 9), China (N = 5), Denmark (N = 1), France (N = 2), Germany (N = 4), Honduras (N=1), Hungary (N=1), India (N=3), Israel (N=1), Iran (N = 7), Malaysia (N=1), Mexico (N=1), Oman (N=1), Spain (N = 5), Sweden (N = 4), Switzdrland (N=1), Turkey (N = 3), the United Kingdom (N=3), and the United States (N=16).
About Eligible Completed Trials
We have identified and extracted data from 156 eligible completed trials. The majority of identified completed trials that have reported results have not provided results that can be meaningfully interpreted due to small sample sizes, poor reporting, and risk of bias concerns. Additionally, most trials use standard interventions not adapted for COVID-19 (e.g., exercise, standard psychotherapy) which limits their potential to inform health policy during the pandemic. However, some trials (e.g. 101948) do provide evidence for feasibly implemented COVID-19 tailored interventions that may be relevant to the general population. And, trial 200001 examines that multi-faceted interventions like SPIN-CHAT have potential to address mental health needs in vulnerable groups during COVID-19, yet uncertainty remains about effectiveness.
