Conflicted and Relevant: Systematic Processing of Information on PFAS Contamination.

Per- and polyfluoroalkyl substances (PFAS) contamination is an emerging environmental and public health crisis. Thus, it is crucial to understand public risk perception and communication behaviors surrounding this issue. Guided by the heuristic-systematic model of information processing, this study explores the impact of conflicting information and personal relevance on information insufficiency and information processing. Through an online experiment, 1,062 U.S. adults were randomly assigned to one of four conditions as part of a 2 (information type: conflicting vs. consistent) × 2 (personal relevance: high vs. low) between-subjects factorial design. Both main effect and interaction effect were detected. Specifically, information insufficiency was highest among participants in the high personal relevance and consistent information condition. Personal relevance also had a main effect on information processing. Conflicting information indirectly elevated information processing through increased information insufficiency, but only when personal relevance was low. These findings suggest the importance of providing consistent and personally relevant information related to the risk of PFAS contamination.

Monkeypox outbreak: Psychological distance, risk perception, and support for risk mitigation.

Building on construal level theory, results from a survey based on a nationally representative sample of U.S. adults (N = 1000) indicate an indirect effect of social distance and temporal distance perception on emotional response, policy support, and vaccination intention through risk perception. This study also reveals that social dominance orientation contributes to perceived psychological distance of the monkeypox outbreak. These results suggest that communication about a public health crisis such as monkeypox needs to emphasize its broader community impact, rather than focusing on the primary population affected.

PFAS Contamination: Pathway from Communication to Behavioral Outcomes.

ABSTRACTGuided by the risk information seeking and processing model, this study examines social cognitive variables that motivate individuals to actively seek and process information related to per- and polyfluoroalkyl substances (PFAS) contamination. Results indicate that information insufficiency, affective response, and informational subjective norms are positively related to information seeking and systematic processing, which are positively associated with policy support and intention to adopt risk mitigation behaviors. These findings suggest that when communicating the health risks of PFAS contamination to the general public, cognitive, affective, and normative factors are important initial steps to generate public interest in relevant information.
