Both questionnaires were sent by email to the relevant psychiatric centers in early January 2020. Centers that failed to reply after 6 weeks were sent a second email and were contacted by telephone to ascertain if they had received the questionnaires. After 4 more weeks, centers that had not responded were phoned again, to repeat the request for information. At this time, the SARS-CoV-2 epidemic broke out and some of these units were transformed into treatment facilities for psychiatric COVID-19 patients. During a telephone contact, a problem with access to statistical data needed to fill in the survey was reported by several units. Eventually, in late June 2020, the epidemic situation began to normalize and the last questionnaires were obtained.
