Information Seeking and Risk Reduction Intentions in Response to Environmental Threat Messages: The Role of Message Processing.

Communicating complex information about environmental health risks in a single message is impossible. Thus, message designers hope that risk messages encourage people to think more about the message and risks, look for more information, and ultimately make behavior changes. The presentation of information about environmental risks using threat appeals is a common message design strategy thought to increase message engagement and influence attitudes, information seeking, and risk reduction behaviors. We compared lower threat messages, which did not include explicit statements about susceptibility and severity of a risk, to higher threat messages, which did. We combined predictions from the extended parallel process model with dual-process theories of persuasion to examine whether people respond to these types of messages differently. In an online experiment, participants (N = 892) were randomly assigned to a message condition (higher or lower threat) and topic condition (arsenic, bisphenol A, or volatile organic compounds). Overall, participants exposed to higher threat messages (regardless of risk topic) reported experiencing higher levels of fear. Higher levels of fear were associated with more positive thoughts about the message (in alignment with the message advocacy) and fewer negative thoughts about the message (against the message advocacy), both of which influenced message attitudes. Finally, message attitudes were associated with increased information seeking and intentions to engage in risk reduction behaviors.

Information Seeking Behaviors and Intentions in Response to Environmental Health Risk Messages: A Test of A Reduced Risk Information Seeking Model.

This study tests the effects of environmental health risk messages on perceived risk, information needs and decisions to seek information, testing a reduced risk information seeking and processing model (R-RISP). Participants (N = 1,823) were randomized to one of three risk conditions (arsenic, bisphenol A [BPA] or volatile organic compounds [VOCs]) and one of the three message conditions (high threat, low threat or no message); participants in the high and low threat message conditions were also randomly assigned to a seeking cue to action condition (with or without seeking cue). Overall, the results support the R-RISP model, demonstrating the importance of current knowledge perceptions and informational subjective norms in information acquisition decisions. In addition, the results also provide initial evidence that environmental health risk messages can prompt information seeking and increase intentions to seek information in the future. Avenues for future research are discussed.

Understanding Associations between Information Seeking and Scanning and Health Risk Behaviors: An Early Test of the Structural Influence Model.

This study examined proposed direct and mediating relationships in the Structural Influence Model (SIM) of Communication within the chronic disease context. Using data from the Annenberg National Health Communication Survey (N = 14,472), we tested the potential mediating roles of information seeking, information scanning, and social capital between social determinants of health and four chronic disease risk behaviors: exercise level, fruit and vegetable intake, cigarette smoking, and excessive alcohol use. Information seeking, information scanning, and social capital received support as potential mediators. Our results are largely consistent with predictions of the SIM and highlight the important role of communication in reducing health risks and increasing healthy behaviors.

An Examination of Adolescent Recall of Anti-Smoking Messages: Attitudes, Message Type, and Message Perceptions.

Delayed message recall may be influenced by currently held accessible attitudes, the nature of the message, and message perceptions (perception of bias and message elaboration). This study examined the potential of message perceptions to mediate the influence of valenced attitude accessibility and message type on unaided recall of anti-smoking Public Service Announcements (PSAs). In a field experiment, ninth grade students (N = 244) watched three PSAs and responded to items on laptop computers. Twelve weeks later, follow-up telephone surveys were conducted to assess unaided recall. Both valenced attitude accessibility and message type were associated with message perceptions. However, only perception of message bias partially mediated the relationship between message type and unaided recall.

Teens' Reactance to Anti-Smoking Public Service Announcements: How Norms Set the Stage.

Data from a study of the effects of anti-smoking ads were analyzed. This study measured the accessibility of peer and parent norms for smoking, exposed teens to three anti-smoking ads that either emphasized personal narratives of the dangers of smoking or had a surprise ending, and measured reactance to the messages. Readiness to smoke was assessed via a phone survey 3 months later. The accessibility of pro-smoking peer norms increased readiness to engage in smoking behavior through reactance toward anti-smoking messages. The accessibility of parent norms was unrelated to reactance. Reactance was particularly strong when the ads included a surprise ending. Peer norms that oppose smoking, particularly if they can be brought to mind quickly, are an important protective factor in that they may reduce reactance to anti-smoking messages.

Heart Disease and Colon Cancer Prevention Beliefs and Their Association With Information Seeking and Scanning.

Despite their understanding of the links between (a) information seeking and scanning and (b) health outcomes, researchers still know relatively little about the impact of information behaviors on people's disease-related beliefs and attitudes. The goal of this study was to validate findings linking information and health behaviors and to assess whether information seeking and scanning are associated with beliefs about the effectiveness of heart disease and colon cancer risk prevention behaviors (in regard to exercise, controlling one's diet to prevent overweight/obesity, and daily fruit and vegetable intake), as well as determine whether the effects of seeking versus scanning on these beliefs differ. Data from the Annenberg National Health Communication Survey were analyzed (N = 3,212). For colon cancer, significant main effects were detected for information scanning for each of the 3 beliefs assessed (p < .05). For heart disease, both information scanning and heart disease media exposure (p < .05) were associated with stronger beliefs. Information seeking was not associated with beliefs for either disease (p > .05). Our results suggest that disease-related cognitions and beliefs, which ultimately impact decisions to engage in prevention behaviors, may be influenced most by less purposeful forms of information acquisition.

Efficiently and Effectively Evaluating Public Service Announcements: Additional Evidence for the Utility of Perceived Effectiveness.

Recent research has made significant progress identifying measures of the perceived effectiveness (PE) of persuasive messages and providing evidence of a causal link from PE to actual effectiveness (AE). This article provides additional evidence of the utility of PE through unique analysis and consideration of another dimension of PE important to understanding the PE-AE association. Current smokers (N =1,139) watched four randomly selected anti-smoking Public Service Announcements (PSAs). PE scores aggregated by message were used instead of individual PE scores to create a summed total, minimizing the likelihood that PE perceptions are consequences of an individual's intention to quit, supporting instead the PE→AE order. Linear regression analyses provide evidence of PE's positive and significant influence on smoking cessation-related behavioral intentions.

Estimating Acceptability of Financial Health Incentives.

A growing body of evidence suggests that financial incentives can influence health behavior change, but research on the public acceptability of these programs and factors that predict public support have been limited. A representative sample of U.S. adults ( N = 526) were randomly assigned to receive an incentive program description in which the funding source of the program (public or private funding) and targeted health behavior (smoking cessation, weight loss, or colonoscopy) were manipulated. Outcome variables were attitude toward health incentives and allocation of hypothetical funding for incentive programs. Support was highest for privately funded programs. Support for incentives was also higher among ideologically liberal participants than among conservative participants. Demographics and health history differentially predicted attitude and hypothetical funding toward incentives. Incentive programs in the United States are more likely to be acceptable to the public if they are funded by private companies.
