  1. GAD-7 7-item General Anxiety Disorder, GHQ-12 12-item General Health Questionnaire, MADRS Montgomery-Asberg Depression Scale, PHQ-9 9-item Patient Health Questionnaire, SF-12 12-item Short Form health survey
  2. aM0, M1, etc. refer to the time-lapse in month to the launch of the intervention while T0, T1, etc. refer to the time-lapse in month to the first connection of the user to the StopBlues program
  3. bT0’ corresponds to the first time that the MINI suicidality module is submitted to the user (this only happens if the user has a bad score at the PHQ-9 and/or at the GAD-7 and/or for the Likert scales of the mood-tracking system which are not used in the evaluation) so T0’ can, therefore, differ from T0. In the case of the level of suicidal risk, T1, T2, T3, T6, T12 and T24, therefore, corresponds to the time after T0’ and not T0
  4. cDepression and anxiety will be measured if the GHQ-12 score suggests potential psychological distress
