In both the 2017 and 2020 surveys, we assessed the presence of mental disorders via the fifth version of the Mini International Neuropsychiatric Interview (M.I.N.I.), a psycho-diagnostic instrument which has demonstrated a high concordance with clinician-assessed diagnosis of mental disorders (Sheehan et al., 1997, 1998). We focused on the prevalence of current (as opposed to life-time) mental disorders; i.e. the presence of examined symptoms within the past 2 weeks for major depressive episode; the past month for panic, posttraumatic stress disorder, social phobia and suicide risk (low, medium or high risk); the past 6 months for generalised anxiety disorder (GAD); and the past 12 months for alcohol use disorders. For agoraphobia, no specific periods are specified in the M.I.N.I.
