Effectiveness of communications in enhancing adherence to public health behavioural interventions: a COVID-19 evidence review

This review examined how communication affected public adherence to COVID-19 safety measures (like distancing, mask use, testing, and staying home) in the UK. Overall, adherence was generally high, but communication quality made a difference. Clear, consistent messages improved compliance, while mixed or confusing guidance reduced it. Trust in government and health authorities was strongly linked to better adherence. Messages that supported autonomy (explaining why actions matter) worked better than overly controlling language. The review recommends using trusted messengers, avoiding conflicting information, and balancing authority with respect to strengthen compliance in future public health emergencies
