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

Health communication has relevance for virtually every aspect of health and well-being, including disease prevention. This review explored the effectiveness of communications in enhancing the adoption of or adherence to behavioural interventions (non-pharmaceutical interventions (NPIs)) related to COVID-19. The review takes the UK as a case study and focuses on self-reported behaviours (e.g. social distancing). It also reviews the psychosocial determinants of adherence. Searches were conducted using PubMed, Scopus, CINAL, ASSIA and iCite databases. Eleven thousand five hundred records were identified and 13 were included in the final sample. Included studies suggest that NPI adoption or adherence was generally high, and communication had significant impacts, with key themes including clarity and consistency, trust and control. Based on the evidence in this review, features of effective communication in the context of NPI adoption or adherence are (i) information should be conveyed clearly and conflicting (mixed) messages should be avoided; (ii) information should be conveyed by trusted sources (e.g. health authorities) and (iii) communication should strike a balance between being authoritative but avoiding language seen as controlling (e.g. 'you must'). Future research should prioritize quantitative, experimental and longitudinal study designs, that focus specifically on communication as an intervention, and which measure behaviour. This article is part of the theme issue 'The effectiveness of non-pharmaceutical interventions on the COVID-19 pandemic: the evidence'.

Ethical leadership supports safety voice by increasing risk perception and reducing ethical ambiguity: Evidence from the COVID-19 pandemic.

Misconduct by business and political leaders during the pandemic is feared to have impacted people's adherence to protective measures that would help to safeguard against the spread of COVID-19. Addressing this concern, this article theorizes and tests a model linking ethical leadership with workplace risk communication-a practice referred to as 'safety voice' in the research literature. Our study, conducted with 511 employees from UK companies, revealed that ethical leadership is positively associated with greater intention to engage in safety voice regarding COVID-19. We also find that this association is mediated by relations with the perceived health risk of COVID-19 and ambiguity about ethical decision making in the workplace. These findings therefore underscore the importance of good ethical conduct by leaders for ensuring that health and safety risks are well understood and communicated effectively by organizational members particularly during crises. We discuss the theoretical and practical implications of our study and highlight further opportunities for future research to address the ethical dimensions of leadership, risk management, and organizational risk communication.

Anticipating or Accommodating to Public Concern? Risk Amplification and the Politics of Precaution Reexamined.

Regulatory use of the precautionary principle (PP) tends to be broadly characterized either as a responsible approach for safeguarding against health and environmental risks in the face of scientific uncertainties, or as "state mismanagement" driven by undue political bias and public anxiety. However, the "anticipatory" basis upon which governments variably draw a political warrant for adopting precautionary measures often remains ambiguous. Particularly, questions arise concerning whether the PP is employed preemptively by political elites from the "top down," or follows from more conventional democratic pressures exerted by citizens and other stakeholders from the "bottom up." This article elucidates the role and impact of citizen involvement in the precautionary politics shaping policy discourse surrounding the U.K. government's "precautionary approach" to mobile telecommunications technology and health. A case study is presented that critically reexamines the basis upon which U.K. government action has been portrayed as an instance of anticipatory policy making. Findings demonstrate that the use of the PP should not be interpreted in the preemptive terms communicated by U.K. government officials alone, but also in relation to the wider social context of risk amplification and images of public concern formed adaptively in antagonistic precautionary discourse between citizens, politicians, industry, and the media, which surrounded cycles of government policy making. The article discusses the sociocultural conditions and political dynamics underpinning public influence on government anticipation and responsiveness exemplified in this case, and concludes with research and policy implications for how society subsequently comes to terms with the emergence and precautionary governance of new technologies under conflict.

The constitution of risk communication in advanced liberal societies.

This article aims to bring to the fore some of the underlying rationales that inform common conceptions of the constitution of risk communication in academic and policy communities. "Normative,""instrumental," and "substantive" imperatives typically employed in the utilization of risk communication are first outlined. In light of these considerations, a theoretical scheme is subsequently devised leading to the articulation of four fundamental "idealized" models of risk communication termed the "risk message" model, the "risk dialogue" model, the "risk field" model, and the "risk government" model, respectively. It is contended that the diverse conceptual foundations underlying the orientation of each model suggest a further need for a more contextualized view of risk communication that takes account not only of the strengths and limitations of different formulations and functions of risk communication, but also the underlying knowledge/power dynamics that underlie its constitution. In particular, it is hoped that the reflexive theoretical understanding presented here will help to bring some much needed conceptual clarity to academic and policy discourses about the use and utility of risk communication in advanced liberal societies.

Terrorism and dispelling the myth of a panic prone public.

Governments and commentators perceive the public to be prone to panic in response to terrorist attacks--conventional or involving chemical, biological or radiological weapons. Evidence from five such incidents suggests that the public is not prone to panic, although people can change their behaviours and attitudes to reduce the risk of themselves being exposed to a terrorist incident. Behavioural responses may be divided into acts of omission, such as not making unnecessary journeys, and acts of commission, such as taking prophylactic medication despite the inherent risk of side effects. Evidence suggests that the public are aware of these differences, and tend to adopt responses proportionate to the risk. Drawing upon the literature in the social and natural sciences, our discussion encompasses differing risk perceptions of terrorist threats and consequences of attacks. How do fear and anxiety interact with behavioural responses to amplify or attenuate perceptions that can be modified through risk communication undertaken by authorities?
