BACKGROUND The way in which different communities respond to similar threats to their health can vary, from outrage to indifference and public health agencies are often taken by surprise leading to potential loss of public confidence. The objective of this systematic literature review was to seek to better understand the community-level drivers that might explain the variability in response. METHODS A vigorous systematic cross-disciplinary literature review was undertaken searching thirteen bibliographic databases and a variety of grey sources were screened. The social amplification of risk framework and the risk perception management theoretical models were used to assess evidence and data were synthesised by Narrative review. FINDINGS Sixteen studies meeting the agreed inclusion criteria described eleven different threats ranging from: infectious disease outbreaks to environmental disasters to cancer clusters, affecting two or more communities were identified from medical, psychological, social science and environmental science literature. There was wide heterogeneity between the type and quality of the studies. There was a general absence of theoretical underpinning community responses. Most studies did not report sufficient data to allow an appropriate amount of validity. Very low response rates in particular were common. Potential explanatory drivers suggested included, prior experience and visibility of threat, sociodemographic characteristics, volume and type of media coverage, government reaction and availability of social support. CONCLUSIONS This review confirmed that there are significant differences. Further work is needed to develop theoretical models that apply to the community level and do not assume that a community's response is simply the aggregate of individual level responses.
