Secondary Outcomes

BackgroundPrevention offers an effective public health strategy for cancer control. One approach that could be incorporated within general practice is the provision of personalised risk information. Few trial data are available concerning the impact of cancer risk information on behaviour.AimTo assess the short-term effects on computed cancer risk and self-reported health-related behaviours of providing personalised cancer risk information.MethodA total of 1018 participants, recruited through the online platform Prolific, were randomised to either a control group receiving cancer-specific lifestyle advice alone or one of three intervention groups receiving the same lifestyle advice alongside their estimated 10-year risk of developing one of the five most common preventable cancers. Cancer risk was calculated from self-reported behavioural risk factors and presented in one of three formats: bar-chart, pictograph, or qualitative scale. The primary outcome was change from baseline in computed risk relative to an individual with a recommended lifestyle (RRI) at 3 months. Secondary outcomes included: self-reported health-related behaviours, accuracy of risk perception, risk conviction, anxiety, worry, intention to change behaviour, self-efficacy, and response-efficacy.ResultsAt immediate follow-up, accuracy of risk perception (P<0.001), risk conviction (P <0.001), and response-efficacy (P = 0.04) increased in all intervention groups. After 3 months there were no between-group differences in change in RRI (P = 0.68) or any of the secondary outcomes.ConclusionThis study has shown that a risk communication intervention can increase short-term risk accuracy and response efficacy and for the first time that risk conviction can be manipulated through risk communication. However, these effects were not sustained over time or associated with behaviour change.

The Impact

Consumers’ food safety risk information-seeking behavior plays a vital role in improving their food quality and safety awareness and preventing food safety risks. Based on the Risk Information Seeking and Processing Model (RISP), this paper empirically analyzes the food safety risk information-seeking intention of consumers in WeChat and influencing factors under the impact of food safety incidents. We use data from 774 WeChat users and apply the Structural Equation Modeling (SEM) approach. We also conduct multigroup analysis with demographic characteristics as moderating variables. The results demonstrated that: (1) Risk perception (p ≤ 0.01) has direct significant positive effects on consumers’ intention to seek food safety information. Besides, higher risk perception (p ≤ 0.01) regarding food safety risks will make people feel more anxious and threatened, and then expand the gap between the information they need and the relevant knowledge they actually have (p ≤ 0.1), which will further stimulate them to seek more information (p ≤ 0.05). (2) Informational subjective norms (p ≤ 0.01) can not only directly affect consumers’ information-seeking about food safety, but also indirectly affect consumers’ intention through information insufficiency (p ≤ 0.01). (3) The more consumers trust the relevant channels (p ≤ 0.01), the stronger their intention to search for food safety risk information. Moreover, the multiple-group analysis also shows that the effects of consumers’ gender, age, educational background, and average monthly earnings are different among different groups. Furthermore, implications are put forward for food safety risk communication efforts in China.

Fair Balance

Purpose The purpose of the study was to examine the effects of prescription drug advertising health risk disclosure prominence and the mediating role of introspective message attention. Design/methodology/approach An experiment was conducted to test varying levels of health risk disclosure prominence in prescription drug advertising (high vs low). Findings The results showed that a more prominent health risk disclosure than a less prominent one enhanced introspective message attention, risk knowledge and risk perception of the drug’s side effects. In addition, the introspective attention mediated the health risk disclosure effects on risk knowledge and risk perception. Research limitations/implications The artificial experimental setting should be considered. In addition, various therapeutic categories and health risk disclosure formats need to be examined. Practical implications To ensure fair balance in prescription drug advertising, message designers should present a sufficient level of health risk disclosure prominence. Social implications To encourage consumers to make informed prescription drug decisions, health risk information provided through prescription drug advertising may be important. Health-marketing promotional messages should address fair balance by considering health risk disclosure prominence. Originality/value Although the FDA has issued its risk communication guidance draft for pharmaceutical manufacturers to ensure fair balance between benefit and risk information in pharmaceutical promotion, little empirical research has been conducted to test the health risk disclosure prominence effects on consumers’ health-related perception about the drug. This study fills the gap in the literature.

Personalized Risk

Abstract Background Major depressive disorder is one of the most prevalent and disabling forms of mental illness in the general population. One public health strategy that may reduce the disease burden is early identification and prevention - identifying people who are at high risk and intervening to prevent symptoms from progressing into a major depressive episode (MDE). Multivariable risk predictive algorithms (MVRP) have been developed to estimate personalized risk (probability) of an MDE. The purpose of this trial is to answer the questions: (1) Does disclosure of personalized depression risk information promote high-risk individuals to take preventive actions? (2) Will disclosure of personalized depression risk information negatively affect the mental health of those at high risk? Methods We are recruiting 350 high-risk men and 350 high-risk women across the country. Individuals are eligible, if they: (1) are 18 years or older, (2) have not had a depressive episode in the past two months, (3) are at high risk of MDE based on the MVRPs (predicted risk of 6.5% + for men and of 11.2% + for women), (4) can communicate in either English or French, and (5) agree to be contacted for follow-up interviews. The MVRPs were developed and validated using longitudinal data from over 10,000 Canadians across the country. Eligible participants are randomized into (1) the control group, and (2) the group receiving personalized depression risk information. The participants are assessed at baseline, 6 and 12 months regarding accuracy of risk perception, use of self-help strategies and changes in psychological distress and functioning. Qualitative interviews are conducted in sub-samples of the intervention groups to explore how the personalized information affects risk perception, self-help behaviors and mental health. Discussion MVRPs can be used for risk stratification and planning preventive actions. The personalized risk information produced by MVRPs may also empower users to actively engage in self-management. This trial will contribute to the knowledge base about the potential health benefits and psychological harms associated with the provision of personalized depression risk information that will inform future implementation and patient-physician communication in the clinical settings.

The Impact

Purpose. To test the hypothesis that responses to coronary heart disease (CHD) risk estimates are heightened by use of ratio formats, peer group risk information, and long time frames. Design. Cross-sectional, experimental, between-factors design. Setting. Three regions in England. Subjects. A total of 740 men and women ages 30 to 70 years. Measures. Risk perception, “emotional” response, intention to change lifestyle. Analysis. Logistic regression was used to investigate the impact of numerical format (ratio vs. percentage), peer group risk (personal vs. peer group), and time frame (10-year vs. 30-year) on risk perception. Analysis of variance was used to investigate the impact of these factors on emotional response and intention to change lifestyle questions. Results. Higher perceived risk was observed when risk was presented as a ratio (p < .001) and when it was supplemented with peer group risk estimates (p = .006). Emotional responses to risk information were heightened when risk was presented as a ratio (p = .0004) and supplemented with peer group risk estimates (p = .002). Presentation with ratios also increased intention to make lifestyle changes (p = .047). Conclusion. Perception of CHD risk information is affected by the presentation format. Where absolute risks may appear low, use of ratios and supplementation of personal risk estimates with peer group risk may increase risk perception.
