The objectives are as follows: To ascertain the state of the science on social support, educational, and behavioural modification interventions to improve all‐hazard household disaster preparedness: The PICO research question is as follows: in the general, non‐institutionalised, community‐dwelling population (P), do social support, educational, and behavioural modification interventions (I) compared to no intervention or usual mass public service messaging (C) improve all‐hazard household disaster preparedness behaviours, supplies, and/or knowledge (O). To assess whether social support, educational, and behavioural modification interventions have effects on healthcare utilisation (emergency department utilisation, hospitalisation, morbidity), mortality, and mental health or physical functioning post disaster.
