A content analysis of EPPM’s threat and efficacy information in environmental news: The impact of a community of practice and topic

The extended parallel process model summarizes the positive impact of threat and efficacy messages on behavioral intentions. In news contexts, research to date shows national journalists emphasize threat information and neglect efficacious information. Findings show U.S. university student journalists emphasized efficacy rather than threats countering past content analysis research. We also found environmental and sustainability communities of practice did not predict threat and efficacy information, but topics did.

Challenges in Media Attention toward COVID-19-Preventive Behaviors: Dual Roles of Threat and Perceived Capability for Information Systems and Health Care

Based on the extended parallel process model, this study investigated the relationship between young adults’ media exposure to COVID-19 and their adoption of protective behaviors. This study surveyed 141 college students and found that increased risk perceptions led to greater intentions to engage in COVID-19-preventive behaviors and that these intentions were mediated by normative beliefs. There was no significant difference in risk perceptions between traditional media and social media. The results showed that college students took precautions against COVID-19 because they perceived themselves to be both vulnerable and capable.

Listen to the Scientists: Effects of Exposure to Scientists and General Media Consumption on Cognitive, Affective, and Behavioral Mechanisms During the COVID-19 Pandemic

Throughout the COVID-19 crisis, scientists around the globe have engaged in science communication to an unprecedented degree to convey first-hand epidemiological knowledge and information on preventive measures. The present work is aimed at empirically investigating the impact of direct exposure to scientists as compared to general COVID-19-related media consumption (N=698) on central cognitive, affective, and behavioral variables, based on the extended parallel process model (EPPM) and its adaptations. A segment of the sample comprises individuals recruited independently, while others were sourced from an online panel. Importantly, this study sample was conducted at the outset of the COVID-19 pandemic. The results revealed that direct exposure to scientists positively affected recipients’ knowledge and self-efficacy. General media consumption, by contrast, positively affected perceived threat as well as fear and uncertainty. Both sources positively affected the adherence to protective measures.

Communicating particulate matter risk: the effects of empoweredness and trust in government information on protective behaviour

ABSTRACT In response to increasing concerns about the health risks associated with air pollution, air quality information and behavioural recommendations are more available to the public through risk communication. However, not all people are willing to change their behaviours; even when they do, the level of action varies. This study investigated how empoweredness (self-efficacy, individual response efficacy, collective response efficacy, hope, and values) and trust in government information affect the protective actions citizens take against particulate matter (PM) risk, by expanding on the extended parallel process model (EPPM). We analyzed the case of Seoul, South Korea, where nationwide environmental concern in regard to PM pollution recently led to intense policy measures and public communication efforts. To test our conceptual model, we conducted an online survey with 513 Seoul citizens on their perception of PM risk and their behaviour during high PM episodes. Our regression results revealed two key findings. First, perceived risk, self-efficacy, individual response efficacy, and trust in government information were positively associated with protective behaviours, supporting our hypotheses. Second and more importantly, trust in government information was found to be moderate the effects of self-efficacy, individual response efficacy, collective response efficacy, and hope on protective behaviour against PM pollution. This suggests trust can be a boundary condition that allows an individual’s empoweredness to be fully extended to behavioural change. Our study demonstrates the possibility of expanding EPPM applications in pro-environmental behaviour studies by adding new variables that can be factored into future risk communication. HIGHLIGHTS We explore the effects of empoweredness and trust in government information on protective behaviour against particulate matter in Korea. Empoweredness is measured by three types of efficacies, hope, and values. Survey responses are statistically analyzed to capture the associations between variables. Self-efficacy, values, and trust are positively associated with protective behaviour. Trust in government moderates some associations between empoweredness and protective action.

Predicting COVID-19 Vaccination Intentions to Inform Evidence-Based Messaging for Building Vaccine Confidence Among Rural Americans.

Examine possible message topics to promote rural vaccination using psychosocial antecedents of vaccination. Cross-sectional survey administered by Research America, Inc. West Virginia (WV). 756 WV adults via convenience sample (n = 370; ∼2% response rate from online panel of ∼20 000 WV residents), and random digit dial of landlines (n = 174; ∼1% response rate from 18 432 numbers) and cellphones (n = 212; ∼1% response rate from 20 486 numbers). Outcome measures included self-reported vaccination intention and behavior. Predictor measures, rooted in theories of social and behavioral science that have been found to be predictive of vaccination outcomes (i.e., Reasoned Action Approach, Extended Parallel Process Model), included perceived severity and susceptibility, negative affect, instrumental and affective attitudes, social norms, self-efficacy, response efficacy, and perceived control. Multivariate linear regression for intention and logistic regression for behavior. Intention was positively predicted by affective attitude, β = .30, P < .05, instrumental attitude, β = .19, P < .05, response efficacy, β = .19, P < .05, negative affect, β = .16, P < .05, self-efficacy, β = .13, P < .05, and subjective norm, β = .13, P < .05, F(10, 267) = 30.12, Adj. R2 = .53. Vaccination status was predicted by instrumental attitude, exp(B) = 2.09, and subjective norm, exp(B) = 2.00, Pseudo R2 = .29, log likelihood = 125.11, χ2(10) = 38.34, P < .05. Promising message targets were instrumental attitude, M = 3.21, SD = 1.46, and subjective norms, M = 3.76, SD = 1.71. COVID-19 vaccine confidence messages should address (1) positive feelings and safety perceptions, (2) vaccination's effectiveness in preventing serious COVID-19, and (3) subjective vaccination norms.

Linguistic agency in disaster messaging: differing strategies for threat and efficacy perceptions

ABSTRACT The purpose of this study was to determine the influence of linguistic assignment of agency on individuals’ perceptions of source credibility; specifically, this study assessed the impact of linguistic assignment of agency when encouraging the public to download a disaster-related mobile app. The experiment was a 2 (human agency and disaster agency) × 3 (low, medium, and high source credibility) between-subjects post-study design. Participants were randomly assigned to one of six messages encouraging them to download the FEMA mobile application. As predicted, high source credibility led to higher perceptions of threat in messages with linguistic agency assigned to disaster. However, when measuring perceptions of efficacy, messages with linguistic agency assigned to humans were more effective. Finally, as predicted by the extended parallel process model, high levels of perception of threat and perception of efficacy predicted a higher likelihood of participants accepting the invitation to download the mobile app.

Psychometric evaluation of a new instrument to hookah tobacco smoking-related factors in the Iranian female university students based on the Extended Parallel Process Model

BACKGROUND: The higher prevalence of hookah tobacco smoking (HTS) has become worrisome in women. Thus, it is essential to identify and measure the perceptions associated with this unhealthy behavior as well as the type of response to risk messages to design the effective programs. This study aimed to psychometric evaluation of a new instrument, named the Extended Parallel Process Model-Hookah Tobacco Smoking Questionnaire (EPPM-HTSQ), for female university students. MATERIAL AND METHODS: This methodological study was conducted in 2019–2020 in central and western Iran. The first version of the instrument was developed with 97 items. Face, Content, and construct validity methods were used to assess the EPPM-HTSQ validity. The data viability for factorability was guided through Kaiser-Meyer-Olkin (KMO) measure of sample adequacy (Values &gt;0.7) and Bartlett’s test of Sphericity (P &lt; 0.05). The Exploratory Factor Analysis (EFA) method with varimax rotation and SPSS software was performed to identify the main factors of the questionnaire and interpretable factors. The internal consistency and external reliability were determined. The test–retest was used for evaluating the stability of tools. RESULTS: During the assessment of the face and content validity 71 items remained in the questionnaire. EFA led to the extraction of nine dimensions: “Focusing on superior rewards,” “Response Efficacy,” “Perceived physical threat,” “Perceived social threat,” “Self-efficacy,” “Fear control,” “Attitude,” “Fear,” and “Intention” Kaiser-Meyer-Olkin (KMO) test (0.957) and Bartlett’s test (P &lt; 0.001). Cronbach’s alpha (0.871–0.951) and ICC (0.985–0.998) were approved for scale dimensions. CONCLUSION: Important findings of the present study were the development and validation of the EPPM-HTSQ for measuring EPPM variables in relation to HTS; introducing a new variable “focusing on superior rewards”; as well as, the new classification of the concept of “perceived threat.” The final version of the EPPM-HTSQ is a valid and reliable tool, but it is suggested to be re-evaluated in other studies with different populations and sample sizes.

Healthcare provider Communication and Data-Informed Message Strategies for Encouraging Older Adults to Stay up to Date on COVID-19 Vaccination.

Older adults are a high in risk of severe COVID-19 disease outcomes and experience "vaccine hesitancy." Guided by health communication models such as the Reasoned Action Approach and the Extended Parallel Process Model, online surveys designed to inform statewide public health communication efforts were administered in West Virginia, a primarily rural and fully Appalachian state, in Winter 2021 (n = 272) and Fall 2022 (n = 248). Adults ages 50+ years (N = 520) reported attitudes, intentions, and behaviors regarding COVID-19 vaccination and their related patient-provider communication. Vaccine usefulness/safety, perceived effectiveness, and subjective norms predicted behavior while perceived severity, efficacy, and usefulness/safety predicted intention to get a booster, specifically the updated Fall 2022 Omicron (bivalent) booster. As patient-provider communication (which a minority reported receiving) was a strong predictor of behavioral outcomes, characteristics of effective healthcare provider communication and considerations for public message construction are discussed.

The Effect of the Extended Parallel Process Model on Self-efficacy of Spouses of Veterans with Post-traumatic Stress Disorder

Background: Spouses of veterans face many psychological problems, so it is necessary to use different methods to manage the care of veterans and their spouses. Objectives: This study aimed to evaluate the effect of the extended parallel process model (EPPM) on the self-efficacy of spouses of veterans with post-traumatic stress disorder (PTSD). Methods: The present study was semi-experimental research carried out by control and intervention groups with a pre-test and post-test design. Thirty veterans' spouses were selected randomly and divided into two groups: The control group (15 people) and the group trained with EPPM (15 people). The intervention type was the training, and the method of implementation of the intervention was holding six sessions. The training was based on EPPM; each session was 30 to 40 minutes. The parenting self-agency measure (PSAM) questionnaire evaluated the self-efficacy variable before and after the intervention. Finally, the results were analyzed using statistical tests in the SPSS software Version 21 environment at the significance level (α = 0.05). Results: The independent samples t-test showed that the self-efficacy level before the intervention was not significantly different among all two study groups (P=0.18). At the same time, this difference was significant after the intervention (P

Application of the extended parallel process model and risk perception attitude framework to obesity knowledge and obesity prevention behaviors among Korean adults

BackgroundPerceiving oneself as obese has been associated with weight loss attempts. However, such a perception may not sufficiently drive significant weight reduction in many individuals. Hence, relying solely on the traditionally emphasized perceived risk of behavioral changes in obesity is challenging. This study used an extended parallel process model and a risk perception attitude framework to explore the influence of perceived risk and perceived efficacy on individual obesity knowledge and obesity prevention behaviors.MethodsData were obtained from 1,100 Korean adults aged 40–69 years through an online survey conducted in October 2022. Multinomial logistic regression and analysis of variance were employed to assess the relationships among perceived risk, perceived efficacy, obesity knowledge, and obesity prevention behaviors.ResultsSex was associated with being underweight, overweight, and obese. Moreover, perceived severity was associated with obesity, whereas perceived susceptibility was associated with overweight and obese. Response efficacy was related to being overweight alone, whereas self-efficacy was associated with being underweight, overweight, and obese. The main effects of sex and perceived risk, and their interaction effect were statistically significant for obesity knowledge. Additionally, the main effects of sex, perceived risk, and perceived efficacy on obesity prevention behaviors were statistically significant.ConclusionsThe extended parallel process model and risk perception attitude framework proved effective in classifying obesity based on body mass index, obesity knowledge, and obesity prevention behaviors.

Mechanisms of Climate Change Media Effects: Roles of Risk Perception, Negative Emotion, and Efficacy Beliefs

ABSTRACT In the context of climate change communication, this study explores the process through which exposure to media messages about a risk leads to recommended behavioral intentions. We propose a model of this process based on the Extended Parallel Process Model (EPPM) and the Risk Perception Attitude (RPA) framework. Our model analyzes how risk perception, negative emotion, and efficacy beliefs mediate and moderate the effects of media messages on people’s intention to engage in pro-environmental behaviors. A national survey among 1,000 adults in South Korea was analyzed, and the fitting of PROCESS Models 4 and 15 yielded four main findings. First, media exposure was directly and positively related to risk perception, negative emotion, and pro-environmental behavioral intention. However, the significant relation between media exposure and behavioral intention was partly conditional upon efficacy beliefs. Second, risk perception and negative emotion were also significantly related to behavioral intention conditional upon efficacy beliefs. Third, efficacy beliefs significantly moderated the relation between risk perception and behavioral intention, but not between negative emotion and behavioral intention. Fourth, efficacy beliefs served as a moderator for the indirect effect of media exposure on behavioral intention via risk perception and negative emotion.

Educational intervention based on the extended parallel process model improves adherence to diabetic diet and glycaemic control indices: a randomised, double-blind, controlled, factorial field trial.

Nutritional education is pivotal in the medical nutritional therapy of type 2 diabetes mellitus (T2DM). The extended parallel process model (EPPM) is a health education method for inducing desirable health behaviours. The present study aimed to investigate the effect of nutritional education based on the EPPM in T2DM patients on knowledge, attitude, practice, anthropometric indices, glycaemic factors, lipid profile and adherence to the diabetic diet. A randomised, double-blind, controlled, factorial field trial was designed for T2DM patients aged 30-59 years (n 88). Participants were randomly allocated into four groups to receive EPPM-based nutritional education through gain framed message (GFM), loss framed message (LFM), their combination (G\LFM) or usual diabetic education in the control group (CG). Participants were assessed before and after the study duration. After 3 months of intervention, eighty participants finished the study. The EPPM-based intervention increased participants' knowledge, behavioural intention, perceived sensitivity, severity, self-efficacy (P < 0·001 for all) and response efficacy (P = 0·029) in comparison with CG. GFM (P = 0·004) and G\FLM (P = 0·034) reduced carbohydrate intake and LFM (P = 0·034) and G\LFM (P = 0·047) decreased fat intake. Between-group analysis indicated interventions reduced weight (P = 0·046), BMI (P = 0·038), fasting blood sugar (P = 0·030), 2-hour postprandial blood glucose (P = 0·027) and TAG (P = 0·002) in comparison with the CG. Results were NS for protein intake, waist and hip circumference, waist:hip ratio, HbA1c, total cholesterol, LDL and HDL. Nutritional education based on EPPM could increase the knowledge and awareness of T2DM patients. Also, it could be beneficial for blood glucose amendment. Further investigations are recommended.

Testing the dominant mediator in EPPM: An empirical study on household anti-malware software users

A key research area in information systems security (ISec) is explaining or improving users’ IS security outcomes via the extended parallel process model (EPPM) lens. While the theoretical construct in emotional valence (e.g., fear) and cognitive valence (e.g., perceived efficacy) were deemed as mediators in previous EPPM-related ISec studies, existing research has ignored the value of testing and reporting the dominant mediator between the emotional valence and the cognitive valence. In this paper, we reintroduce the theoretical origins of the dominant mediator assumption in EPPM and highlight its merits using the multiple mediation method. Theoretically, we illustrate how testing and reporting the dominant mediator can help identify the dominant mechanism triggering specific behavioral outcomes. Further, this paper questions the dominant mediating role of fear on the behavioral outcome in ISec context. Methodologically, this study proposes to assess the dominant mediator via a multiple mediation model instead of using the discriminant value equation introduced by Witte (1995), Witte et al. (1996) and enhanced by Chen et al. (2021) when testing the EPPM theory in the ISec context.

Falling Into the Same Hole: Leaving Cigarette, Approaching E-Cigarette

Effective communication regarding the risks associated with electronic cigarettes is a crucial part of efforts to control their usage, and incorporating elements of fear is an effective method to achieve proper regulation. This research, utilizing content analysis methodology, examined three online news articles from Indonesian news portals: Kompas.com, IDNTimes.com, and Detik.com. The study aimed to describe how online news conveys the dangers of using electronic cigarettes using the Extended Parallel Process Model (EPPM). The research method employed was content analysis. EPPM explains how people manage the fear evoked by threat messages. There are two key factors that can explain how individuals respond to fear messages. The first factor is the perception of threat, consisting of the severity and vulnerability to the threat. The second factor is the perception of efficacy, consisting of response efficacy and self-efficacy. The research findings indicate that online news coverage prioritizes the perception of threat. Conversely, the aspect of efficacy perception still needs to be applied in reporting the dangers of electronic cigarettes. These results are also influenced by ethical codes, journalistic principles, and cultural influences.

Boil water notices as health-risk communication: risk perceptions, efficacy, and compliance during winter storm Uri

Winter Storm Uri was a disaster that impacted much of the United States during February of 2021. During and after the storm, Texas and Oklahoma experienced massive power grid failures. This led to cascading impacts, including water system disruptions and many boil water notices (BWNs). The breakdown of some communication channels and the inability to enact protective actions due to power outages, as well as travel limitations on public roads, complicated the dissemination and implementation of notifications. This research examined individuals’ perceptions of risk, water quality, and BWNs during Uri. Additionally, this study sought to understand if previous experience with a BWN influenced compliance during Uri and how perceived efficacy impacted these variables. Surveying 893 Texans and Oklahomans revealed that most Uri-affected respondents believed the risks associated with BWNs were severe. Income and race were two factors that influenced BWN compliance. Age, gender, and level of education did not influence compliance. Previous experience with BWNs did not increase risk perceptions. Higher levels of perceived efficacy correlated to higher levels of compliance, perceptions of risk, and water quality, much of which support propositions of the Extended Parallel Process Model. Results suggest that pre-disaster planning and communication are imperative to helping reduce risk(s) and enhancing efficacy during a disaster, especially for novel disasters that have cascading risks, like Winter Storm Uri.

COVID-19 in social media: the effect of fear appeal messages in Facebook on users’ perception of hygienic measures to prevent contracting the disease

With the outbreak of COVID-19 in late 2019, a massive wave of fear appeal messages related to this disease was published on social media platforms, including Facebook. This research uses the Extended Parallel Process Model (EPPM) to explore the impact of COVID-19 related fear appeal messages in Facebook on the perception of hygienic measures of Facebook users in Afghanistan. A nationwide paper-and-pen survey was conducted among Facebook users exposed to fear appeal messages related to COVID-19 in five highly populated cities in Afghanistan. The EPPM questionnaire was developed using the World Health Organization’s recommendations for preventive hygiene. By using the stratified random sampling method, 425 participants were selected. Pearson correlation coefficients and multilinear regression tests were used to analyze the data. The results show a significant relationship between exposure to fear appeal messages related to COVID-19 and perceptions of threat severity, susceptibility to COVID-19, self-efficacy, and response efficacy. The multilinear regression results show that exposure to fear appeal messages can help us predict the perception of threat severity and susceptibility. Finally, Facebook users in this study perceived a higher level of threat of COVID-19 than their level of perception of self-efficacy, so they were led to the process of fear control.

Investigating the factors related to protective behaviors against COVID-19 in healthcare workers: Application of extended parallel process model.

Preventive behaviors against coronavirus disease 2019 (COVID-19) are important, and messages that create a sense of danger are necessary to create these behaviors. One of the widely used models for designing risk messages is the Extended Parallel Process Model (EPPM). The present study was conducted to investigate the factors related to protective behaviors against COVID-19 in the personnel of the health department based on EPPM. In this cross-sectional study, 699 personnel of the deputy health department of Chaharmahal and Bakhtiari province were included in the study by census method. Data were collected online using valid questionnaires, including demographic questions and history of contracting COVID-19 and the questionnaire of EPPM constructs. Data were analyzed in SPSS24 software, using descriptive and analytical statistics. The results showed that there were positive correlations between the protective behaviors and the constructs of perceived severity (p < 0.001, r = 0.542), perceived susceptibility (p < 0.001, r = 0.260), self-efficacy (p < 0.001, r = 0.594), response efficiency (p > 0.001, r = 0.522), and risk control (p > 0.001, r = 0.501). There was a negative correlation between protective behaviors and fear control (p < 0.001, r = 0.329). The results of multiple linear regression showed that these six constructs explained 49.8% of protective behaviors against COVID-19, among which the role of the perceived severity construct was stronger than other constructs. Regarding the results, it is suggested that the results of this research be used in the development of training programs to improve protective behaviors in high-traffic offices, and by focusing on fear and risk control.

Understanding the Design of Fear Appeals by Applying the Extended Parallel Process Model: A Qualitative Analysis of COVID-19 Public Service Announcements.

Identify how early COVID-19 public health messages incorporated in the tenets of the extended parallel process model (EPPM). YouTube videos developed by governmental departments, medical institutions, news organizations, and non-profit organizations in the United States were aggregated. This qualitative study conducted a keyword search to identify public service announcements (PSAs). The sample was further refined after searching PSAs that contained fear appeals. A thematic analysis was performed by using the constant comparative method. A total of forty-three videos was included in the final analysis. Two themes emerged regarding messages aimed at arousing the perceived severity of threat. These themes include emphasizing the consequences of being infected and utilizing personal narratives. Perceived susceptibility of threat was aroused by emphasizing that some groups have higher risks than others. Two themes emerged around arousing perceived response efficacy: (1) the authority of professionals; and (2) altruism and personal responsibility. One way was identified to arouse perceived self-efficacy, which is informing the protective measures. Multiple strategies were used in PSAs about COVID-19 to arouse fear during the early stages of the pandemic. The utilization of self-efficacy was oversimplified, by not providing details about the rationale for the recommended behavior.

Adding hope to mitigate defensive responses: the effect of guilt+hope appeals in road safety campaigns

Purpose Guilt appeals are increasingly being used in road safety campaigns, despite recent research that has raised doubts about their effectiveness and the potential for triggering defensive responses. Building on the extended parallel process model, this study aims to add to this growing body of research by evaluating whether combining a hope message with guilt appeals can solve this problem. Design/methodology/approach An online experiment with a 2 (Appeal type: Guilt vs Guilt+hope) × 2 (Language intensity: Low vs High) between-subjects design was conducted. A total of 399 participants recruited from Amazon’s Mechanical Turk were randomized to view one of the four advertisements discouraging texting while driving (TWD). Their affective responses, perceptions about the advertisements and intentions to not TWD were measured. Findings The results showed that compared to guilt-only appeals, guilt+hope appeals directly reduced defensive responses (i.e. perceived manipulative intent and anger) across varying levels of language intensity. In addition, guilt+hope appeals mitigated the negative impacts of manipulative intent on intended emotions and intentions to not TWD. Originality/value Findings of this study mark the first to support the idea that communicating hope within guilt appeals is a promising social marketing strategy to discourage TWD.

Cardiovascular disease threat and perceived efficacy of selected preventive behaviors among Polish men: an analysis based on the extended parallel process model.

Considering the low rate of preventive behaviors (5%), it is important to increase the effectiveness of actions that motivate the public to engage in health-promoting behaviors. The purpose of this study was to assess the way in which Polish men perceive the threat of cardiovascular diseases (CVDs) and the effectiveness of five preventive behaviors in the context of CVDs. We aimed to identify groups of recipients, based on the extended parallel process model (EPPM), for five preventive behaviors and to compare the identified groups in terms of selected characteristics. We conducted the survey in November 2022, using the computer-assisted web interviewing technique, on a representative sample of 1,000 men aged 18-65 years. Polish men showed relatively low levels of perceived susceptibility to CVDs (15.1%), but at the same time tended to perceive the consequences of CVDs as severe (54.2%). Segmentation of audiences according to the EPPM showed that regardless of the type of preventive behavior, the most numerous groups are responsive (31-37%) and indifferent (29-31%). This study revealed the need to increase awareness of the importance of a healthy diet to prevent CVDs among male population. Less than half of the men indicated that they would be able to implement effective stress management (49.8%) and smoking avoidance (39.4%), indicating the need to implement measures to increase self-efficacy in the areas.
