Abstract

Public support for behavioral COVID-19 measures was essential for effective pandemic control. An initial Dutch cohort study (2020–2021) found consistently high support for most measures, with variations by type of measure and demographic subgroup. The study showed no general decline over time, suggesting support was shaped by perceived costs and benefits rather than pandemic fatigue. Building on this, a second study (2020–2022) examined both support and actual adherence, using longitudinal data aligned with shifts in pandemic severity and policy stringency. It confirmed the earlier findings and added that adherence remained relatively stable, with testing compliance increasing after official recommendations. The study also showed that support and adherence followed distinct patterns and were influenced by different factors. Together, these studies highlight that behavioral responses are dynamic and context-sensitive. Rather than reflecting fatigue, public attitudes represent nuanced evaluations, underscoring the need for adaptive, targeted communication and policy.
