MIND/COVID-19: Mental health Impact and NeeDs associated with COVID-19: a comprehensive national evaluation in Spain.

A prospective cohort study of three groups: (1) COVID-19 cases or close contacts recently isolated or quarantined; (2) healthcare workers; and (3) the general population, including both adults and children / adolescents. Recruitment through epidemiologic surveillance services, hospitals, primary care centers in 6 Spanish Autonomous Communities (groups 1 & 2), a panel survey (group 3 - adults), and snowball sampling through social media (group 3 - children / adolescents). Web-based surveys at baseline and 6-month follow-up assess: current living and employment status; COVID-19 infection status; mental health (post-traumatic stress, panic, depression, anxiety, alcohol use, suicidality; services use); psychological functioning; health and quality of life. Specific modules focus on impact of isolation or quarantine (group 1) and care for COVID-19 patients (group 2). Children / adolescents receive adapted modules. Smartphone-based daily brief surveys among groups 1 & 2 will provide additional assessment of main outcomes in the two weeks following baseline assessment.
