Effectiveness of the extended parallel process model in promoting colorectal cancer screening

Improving communication to increase uptake of high-risk breast cancer prevention appointments: Building a better letter

Objective

Mailed letters to women identified as being at high-risk for developing breast cancer were not having the desired effect for encouraging appointments with prevention-focused providers at a large Midwest healthcare system. A partnership with communication scholars sought to revise the letter to increase awareness, intentions, and appointments.

Methods

Guided by the Extended Parallel Process Model, survey responses were collected from letter recipients over the course of two years, both pre and post letter revision. Appointments attributed to letters were also tracked.

Results

Recipients of the revised letter had increased knowledge regarding the length of prevention appointments and indicated greater self-efficacy and intentions to make and attend appointments compared to those who received the non-revised letter. A greater percentage who received the revised letter also made appointments.

Conclusion

Partnering with communication scholars helped with improving a letter mailed to thousands of patients each year. Finding ways to increase response-efficacy of breast cancer prevention activities within communications may assist in increasing appointments.

Innovation

Cross-disciplinary partnerships across the medical and social sciences - while not quick or simple - are essential for finding ways to improve patient wellbeing and hopefully reducing the prevalence of preventable diseases in the future.

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.

Communicating Antibiotic Resistance via Linguistic Agency Assignment

Antibiotic resistance is a serious health threat that healthcare providers must communicate to the public to decelerate its development. Prior studies have shown that linguistic agency assignment is a viable strategy to frame health threats in a way that both conveys their severity and preserves audience members' sense of self-efficacy. In the current study, we examined this messaging strategy in the context of antibiotic resistance. Individuals' perceptions of the threat and efficacy, behavioral intentions, fear appeals, and evaluations of the educational fact sheet were explored. Participants (N = 449) were randomly assigned to one of the eight conditions crossing threat agency (bacteria/human), temporal agency (antibiotic resistance/human) and imagery agency (taking antibiotics/antibiotics). The results revealed that individuals' perceived severity, susceptibility, response efficacy, and self-efficacy were positively associated with their intentions to use antibiotics judiciously. The interaction effects between perceived threat and efficacy predicted behavioral intentions and the persuasiveness of the fact sheet. Relative to bacteria threat agency, human agency assignment led to significantly higher behavioral intentions. Also, readers of the human temporal agency condition reported higher persuasiveness toward the fact sheet than readers of the resistance condition. The implications, limitations, and future research directions of the study are discussed.

Identifying Mediators of Intervention Effects Within a Randomized Controlled Trial to Motivate Cancer Genetic Risk Assessment Among Breast and Ovarian Cancer Survivors

BACKGROUND

A theory-guided Tailored Counseling and Navigation (TCN) intervention successfully increased cancer genetic risk assessment (CGRA) uptake among cancer survivors at increased risk of hereditary breast and ovarian cancer (HBOC). Understanding the pathways by which interventions motivate behavior change is important for identifying the intervention's active components.

PURPOSE

We examined whether the TCN intervention exerted effects on CGRA uptake through hypothesized theoretical mediators.

METHODS

Cancer survivors at elevated risk for HBOC were recruited from three statewide cancer registries and were randomly assigned to three arms: TCN (n = 212), Targeted Print (TP, n = 216), and Usual Care (UC, n = 213). Theoretical mediators from the Extended Parallel Process Model, Health Action Planning Approach, and Ottawa Decision Support Framework were assessed at baseline and 1-month follow-up; CGRA uptake was assessed at 6 months. Generalized structural equation modeling was used for mediation analysis.

RESULTS

The TCN effects were most strongly mediated by behavioral intention alone (β = 0.49 and 0.31) and by serial mediation through self-efficacy and intention (β = 0.041 and 0.10) when compared with UC and TP, respectively. In addition, compared with UC, the TCN also increased CGRA through increased perceived susceptibility, knowledge of HBOC, and response efficacy.

CONCLUSIONS

Risk communication and behavioral change interventions for hereditary cancer should stress a person's increased genetic risk and the potential benefits of genetic counseling and testing, as well as bolster efficacy beliefs by helping remove barriers to CGRA. System-level and policy interventions are needed to further expand access.

Embodying Temporality in Response Efficacy: How Coping Appraisal Promotes Preventive Behavioral Engagement During the Ongoing Pandemic

This study heightens the understanding of response efficacy as a determinant of engagement in preventive behavior during the ongoing COVID-19 pandemic. To achieve a more nuanced conceptualization of response efficacy, this study proposes and examines a time-based coping appraisal framework, drawing upon a part of the extended parallel process model (EPPM). The current study investigates how the temporality of coping response message features work in generating social distancing behavioral intentions and explicates the role of anticipated emotions in this motivational process. Results of the experimental study (N = 584) indicate that proximal future framed coping response message (vs. distant future message) led to greater response efficacy, which in turn led to greater anticipated guilt and pride, and by extension increased social distancing behavioral intentions. Mediation analyses also demonstrated the indirect effects of the temporality conditions (proximal future-oriented message vs. distant future-oriented message) on social distancing intentions through response efficacy, anticipated guilt, and anticipated pride. The theoretical and practical implications of this study are discussed.

When Cigarette Smoking Meets COVID-19: How the Two Types of Threat and Efficacy Perceptions Interactively Predict Danger Control and Fear Control Processes

Growing evidence indicates that communicating the combined risk of smoking and COVID-19 encourages smoking cessation. Guided by the Extended Parallel Process Model (EPPM), we examined how perceived threats of smoking and COVID-19 independently and interactively predicted danger control responses (i.e., quit intentions and COVID-19-protective behavioral intentions) and fear control responses (i.e., fear and fatalism). We also explored the direct and interactive impacts of perceived efficacy of quitting smoking and COVID-protective behaviors on message outcomes. Structural equation modeling results (N = 747 U.S. adults who smoke) indicated that the perceived efficacy of COVID-protective behaviors positively predicted quit intentions. Higher perceived threat of COVID-19 and greater quitting efficacy predicted higher quit intentions directly and indirectly via fear. As perceived COVID-protective efficacy increased, the positive association between perceived quitting efficacy and quit intentions also increased. Smoking-related threat and efficacy perceptions did not predict COVID-protective behavioral intentions. This study added to EPPM by considering how threat and efficacy perceptions deriving from two different yet closely related risks affect protective behaviors. Thus, combining multiple threats in a single message might be a promising strategy to motivate smoking cessation amid the pandemic.

Recommending Breast Cancer Screening to My Mum: Examining the Interplay of Threat, Efficacy, and Virality on Recommendation Intention in the Chinese Context

The burgeoning eHealth campaigns and the emerging daughter-to-mother health communication necessitate a close examination of the intricate mechanism behind recommending preventive behaviors in online settings. The present study addresses existing gaps by investigating how message characteristics and platform-generated virality cues jointly influence younger females' intention to recommend breast cancer screening to their mothers. Drawing on the extended parallel process model (EPPM) as the theoretical basis, a 2 (threat: low vs. high) × 2 (efficacy: low vs. high) × 2 (virality: low vs. high) randomized between-subjects experiment (n = 269) was performed. Results revealed a three-way interaction effect between threat, efficacy, and virality on message involvement. Message involvement was positively associated with recommendation intention and mediated the three-way interaction effect on recommendation intention. This study demonstrates that a high threat can initiate message involvement but fail to trigger recommendation intention. In contrast, a low-threat, high-efficacy, high-virality combination would yield a salutary outcome. Besides, the indispensable role of message involvement in the underlying psychological mechanism behind recommending preventive behaviors was reaffirmed. Theoretical and practical implications are further discussed.

Understanding cancer genetic risk assessment motivations in a remote tailored risk communication and navigation intervention randomized controlled trial

Background

National guidelines recommend cancer genetic risk assessment (CGRA) (i.e. genetic counseling prior to genetic testing) for women at increased risk for hereditary breast and ovarian cancer (HBOC). Less than one-half of eligible women obtain CGRA, leaving thousands of women and their family members without access to potentially life-saving cancer prevention interventions.

Purpose

The Genetic Risk Assessment for Cancer Education and Empowerment Project (GRACE) addressed this translational gap, testing the efficacy of a tailored counseling and navigation (TCN) intervention vs. a targeted print brochure vs. usual care on CGRA intentions. Selected behavioral variables were theorized to mediate CGRA intentions.

Methods

Breast and ovarian cancer survivors meeting criteria for guideline-based CGRA were recruited from three state cancer registries (N = 654), completed a baseline survey, and were randomized. TCN and targeted print arms received the brochure; TCN also participated in a tailored, telephone-based decision coaching and navigation session grounded in the Extended Parallel Process Model and Ottawa Decision Support Framework. Participants completed a one-month assessment. Logistic regression was used to compare the rate of CGRA intentions. CGRA intentions and theorized mediator scores (continuous level variables) were calculated using mixed model analysis.

Results

CGRA intentions increased for TCN (53.2%) vs. targeted print (26.7%) (OR = 3.129; 95% CI: 2.028, 4.827, p < .0001) and TCN vs. usual care (23.1%) (OR = 3.778, CI: 2.422, 5.894, p < .0001). Perceived risk (p = 0.023) and self-efficacy (p = 0.035) mediated CGRA intentions in TCN.

Conclusions

Improvements in CGRA intentions and theorized mediators support the use of a tailored communication intervention among women at increased HBOC risk. (Clinicaltrials.gov: NCT03326713.)Trial registration: ClinicalTrials.gov identifier: NCT03326713.

Can virtual human clinicians help close the gap in colorectal cancer screening for rural adults in the United States? The influence of rural identity on perceptions of virtual human clinicians

Rural adults experience disparities in colorectal cancer screening, a trend even more distinct among rural Black adults. Healthcare disruptions caused by COVID-19 exacerbated inequities, heightening attention on virtual communication strategies to increase screening. Yet little is known about how rural adults perceive virtual human clinicians (VHCs). Given that identifying as rural influences perceived source credibility often through appearance judgments, the goal of this pilot was to explore how to develop VHCs that individuals highly identified with rurality find attractive. Between November 2018 and April 2019, we tested a culturally tailored, VHC-led telehealth intervention delivering evidence-based colorectal cancer prevention education with White and Black adults (N = 2079) in the United States recruited through an online panel who were non-adherent to screening guidelines and between 50 and 73 years of age. Participants were randomized on three factors (VHC race-matching, VHC gender-matching, Intervention type). Ordinal logistic regression models examined VHC appearance ratings. Participants with a high rural identity (AOR = 1.12, CI = [1.02, 1.23], p =.02) rated the VHCs more attractive. High rural belonging influenced VHC attractiveness for Black participants (AOR = 1.22, CI = [1.03, 1.44], p =.02). Also, Black participants interacting with a Black VHC and reporting high rural self-concept rated the VHC as more attractive (AOR = 2.22, CI = [1.27, 3.91], p =.01). Findings suggest adults for whom rural identity is important have more positive impressions of VHC attractiveness. For patients with strong rural identities, enhancing VHC appearance is critical to tailoring colorectal cancer prevention interventions.

Risk Awareness and Impediments to Disaster Preparedness of Foreign Residents in the Tokyo Metropolitan Area, Japan

The likelihood of a mega-earthquake, the COVID-19 pandemic, and the threat of other disasters in the Tokyo Metropolitan area have necessitated collective responsibilities to take all possible actions to reduce their impacts. The experiences from past disasters have, however, highlighted the plight of foreign residents in coping with disasters and have reinvigorated calls for rigorous counteractions. As the population of foreign residents continues to increase in the metropolis, this research examines their awareness of risks and the obstacles that hinder disaster preparedness in the wake of future disasters. An Extended Parallel Process Model is utilized to analyze both secondary and primary data sources, and the results reveal that 65% perceive the severity of disaster as a threat and believe in a likelihood of occurrence in the city; however, the confidence to undertake some recommended countermeasures are lacking (with low efficacy of 70%). This is causing many to control their fear by not actively seeking further risk information or participating in disaster prevention activities. In consideration of these instances, the study recommends a collective approach built upon the merits of stakeholder engagements to provide vicarious experiences, verbal persuasions, and mastery experiences to boost the response capacities of foreign residents for disaster preparedness. This will be relevant for city authorities to enhance risk communication and foster foreigner-Japanese community integration.

Effect of fear appeal mobile phone messaging on health behaviors of caregivers with children under-five in Ghana

Social and Behavior Change Communication is a vital strategy in the control of malaria. However, the effectiveness of fear appeal tactic as a preventive strategy remains uncertain. This study examined the influence of a fear appeal mobile phone-based intervention, guided by Witte's Extended Parallel Process model, on malaria prevention among caregivers with children under-five. We conducted a quasi-experimental study of a 12-month intervention using a sample of 324 caregivers from two rural districts, assigned to either an intervention or control group. The intervention group received fear appeal voice Short Message Service (SMS), once a week for twelve (12) months, while caregivers in the control group received none. The results showed that exposure to the messages was associated with an increased odds of positive attitude [adjusted Odds ratio (aOR) = 2.58; 95% CI 1.61-4.15] and behavioral changes (aOR = 2.03, 95% CI 1.29-3.19). The intervention group exhibited lower odds of defensive avoidance (aOR = 0.44, 95% CI 0.29-0.68) and message minimization (aOR = 0.51, 95% CI 0.33-0.78) compared with the control group. These findings highlight the importance of communicating health messages via mobile phones using fear appeal for improving the health behaviors of caregivers. This strategy, however, may not be useful for influencing the intention of caregivers to engage in positive health practices to protect their children from malaria.

Predicting college students' COVID-19 vaccination behavior: an application of the extended parallel process model

The two studies reported in the paper examined (1) the extended parallel process model’s (EPPM; Witte 1992) ability to predict and explain college students’ COVID-19 vaccination behavior, and (2) the EPPM-related reasons for college students’ COVID-19 vaccine hesitancy. Study 1 was a longitudinal study that measured the EPPM constructs at Time 1 and COVID-19 vaccine behavior two months later at Time 2. For danger control, results indicate that perceived threat and perceived efficacy positively predicted intentions and that intentions positively predicted behavior. For fear control, results indicate that perceived threat positively predicted fear, that perceived efficacy did not predict fear, and that fear negatively predicted defensive avoidance, reactance, and fatalism. Study 2 was a cross-sectional survey that assessed EPPM-related reasons for vaccine hesitancy. Results indicate that the main reasons for vaccine hesitancy were related to response efficacy (i.e., participants were concerned about the safety and effectiveness of the vaccine). The theoretical and practical implications of these results are discussed.

An extended health belief model for COVID-19: understanding the media-based processes leading to social distancing and panic buying

Building on the health belief model (HBM), this research tests, over six months, how the exposure to COVID-related information in the media affects fear, which in turn conditions beliefs about the severity of the virus, susceptibility of getting the virus, and benefits of safety measures. These health beliefs ultimately lead to social distancing and panic buying. As a first contribution, we find that fear is not directly triggered by the objective severity of a crisis, but rather formed over time by the way individuals are exposed to media. Second, we show that fear affects behaviors through the components of the HBM which relate to the risks/benefits of a situation. Last, we find that critical thinking about media content amplifies the "adaptive" responses of our model (e.g., health beliefs, social distancing) and reduces its "maladaptive" responses (e.g., panic buying). Interestingly, we note that the beneficial effect of critical thinking about media content disappears as the level of fear increases over time. The implications of these findings for policymakers, media companies, and theory are further discussed.

Motivating cascade testing for familial hypercholesterolemia: applying the extended parallel process model for clinician communication

Motivating at-risk relatives to undergo cascade testing for familial hypercholesterolemia (FH) is critical for diagnosis and lifesaving treatment. As credible sources of information, clinicians can assist in family communication about FH and motivate cascade testing uptake. However, there are no guidelines regarding how clinicians should effectively communicate with probands (the first person diagnosed in the family) and at-risk relatives. Individuals and families with FH can inform our understanding of the most effective communications to promote cascade testing. Guided by the extended parallel process model (EPPM), we analyzed the perspectives of individuals and families with FH for effective messaging clinicians can use to promote cascade testing uptake. We analyzed narrative data from interviews and surveys collected as part of a larger mixed-methods study. The EPPM was used to identify message features recommended by individuals and families with FH that focus on four key constructs (severity, susceptibility, response efficacy, self-efficacy) to promote cascade testing. Participants included 22 individuals from 11 dyadic interviews and 98 survey respondents. Participants described prioritizing multiple messages that address each EPPM construct to alert relatives about their risk. They illustrated strategies clinicians could use within each EPPM construct to communicate to at-risk relatives about the importance of pursuing diagnosis via cascade testing and subsequent treatment for high cholesterol due to FH. Findings provide guidance on effective messaging to motivate cascade testing uptake for FH and demonstrates how the EPPM may guide communication with at-risk relatives about genetic risk and motivate cascade testing broadly.

Telehealth and racial disparities in colorectal cancer screening: A pilot study of how virtual clinician characteristics influence screening intentions

Introduction

Racial disparities in colorectal cancer (CRC) can be addressed through increased adherence to screening guidelines. In real-life encounters, patients may be more willing to follow screening recommendations delivered by a race concordant clinician. The growth of telehealth to deliver care provides an opportunity to explore whether these effects translate to a virtual setting. The primary purpose of this pilot study is to explore the relationships between virtual clinician (VC) characteristics and CRC screening intentions after engagement with a telehealth intervention leveraging technology to deliver tailored CRC prevention messaging.

Methods

Using a posttest-only design with three factors (VC race-matching, VC gender, intervention type), participants (N = 2267) were randomised to one of eight intervention treatments. Participants self-reported perceptions and behavioral intentions.

Results

The benefits of matching participants with a racially similar VC trended positive but did not reach statistical significance. Specifically, race-matching positively influenced screening intentions for Black participants but not for Whites (b = 0.29, p = 0.10). Importantly, perceptions of credibility, attractiveness, and message relevance significantly influenced screening intentions and the relationship with race-matching.

Conclusions

To reduce racial CRC screening disparities, investments are needed to identify patient-focused interventions to address structural barriers to screening. This study suggests that telehealth interventions that match Black patients with a Black VC can enhance perceptions of credibility and message relevance, which may then improve screening intentions. Future research is needed to examine how to increase VC credibility and attractiveness, as well as message relevance without race-matching.

Effectiveness of a tailored communication intervention on colonoscopy uptake for firstdegree relatives of colorectal cancer patients: A randomised controlled trial

Objective

To evaluate the effect of a WeChat tailored communication intervention on colonoscopy uptake and health beliefs in Chinese first-degree relatives (FDRs) of colorectal cancer patients.

Methods

This study employed a single-blinded randomized controlled trial. A total of 188 eligible FDRs were recruited and randomly assigned to the tailored intervention group or control group. Health beliefs were assessed at 1 (T1) and 3 months (T2) postintervention. The colonoscopy uptake was verified by medical records at T2. Data were analyzed using binary logistic regression and generalized estimating equation models.

Results

Compared with the participants in the control group, those in the intervention group had a significant improvement in terms of colonoscopy uptake (OR = 2.752, 95% CI: 1.428–5.303, P ​< ​0.01), perceived susceptibility (T1: β ​= ​0.298, 95% CI: ​0.052–0.402, P ​< ​0.05; T2: β ​= ​0.251, 95% CI: ​0.078–0.424, P ​< ​0.001) and cues to action (T1: β ​= ​0.0.264, 95% CI: ​0.138–0.389, P ​< ​0.001; T2: β ​= ​0.327, 95% CI: ​0.195–0.459, P ​< ​0.001) and a significant reduction in perceived barriers (T1: β ​= ​−0.237, 95% CI: ​−0.360−0.115, P ​< ​0.01; T2: β ​= ​−0.196, 95% CI: ​−0.331−0.062, P ​< ​0.01).

Conclusions

This study broadens the application of tailored communication using novel channels in the context of screening in the at-risk Chinese population. The results provide insights on how to improve the intervention by modifying its components and communication channels.

Communicating risk to promote colorectal cancer screening: a multi-method study to test tailored versus targeted message strategies

Colorectal cancer (CRC) screening rates are suboptimal, partly due to poor communication about CRC risk. More effective methods are needed to educate patients, but little research has examined best practices for communicating CRC risk. This multi-method study tests whether tailoring CRC risk information increases screening intentions. Participants (N = 738) were randomized with a 2:2:1 allocation to tailored, targeted, and control message conditions. The primary outcome was intention to screen for CRC (yes/no). Additional variables include perceived message relevance, perceived susceptibility to CRC, and free-text comments evaluating the intervention. A chi-square test determined differences in the proportion of participants who intended to complete CRC screening by condition. A logistic-based path analysis explored mediation. Free-text comments were analyzed using advanced topic modeling analysis. CRC screening intentions were highest in the tailored intervention and significantly greater than control (P = 0.006). The tailored message condition significantly increased message relevance compared with control (P = 0.027) and targeted conditions (P = 0.002). The tailored condition also increased susceptibility (P < 0.001) compared with control, which mediated the relationship between the tailored condition and intention to screen (b = 0.04, SE = 0.02, 95% confidence interval = 0.02, 0.09). The qualitative data reflect similar trends. The theoretical mechanisms and practical implications of tailoring health education materials about CRC risk are discussed.

Using Facebook to promote the uptake of colorectal cancer screening

Background

The use of social media presents a unique opportunity for cancer screening programs to motivate individuals to get screened. However, we need a better understanding of what types of social media messages for colorectal cancer (CRC) screening are preferred. The objective of this study was to develop social media messages promoting CRC screening uptake to identify messages preferred by the target audience.

Methods

We conducted a qualitative descriptive study and collected data through focus groups with Facebook users of screen-eligible age. Participants were presented with social media messages and asked to provide feedback. Messages were informed by the Health Belief Model, current evidence regarding screening communication and health communication and social media best practices. Focus groups were audio-recorded and transcribed and analysis was completed by two independent coders. If messages generated sufficient discussion, we developed a recommendation regarding the use of the message in a future social media campaign. Recommendations included: strongly consider using this message, consider using this message, proceed with caution, and do not use this message. General considerations about social media campaigns were also noted.

Results

A total of 45 individuals participated in six focus groups. We developed recommendations for 7 out of the 18 messages tested; 1 was classified as strongly consider using this message, 4 as consider using this message and 2 as proceed with caution. The data suggest that participants preferred social media messages that were believed to be credible, educational, and with a positive or reassuring tone. Preferred messages tended to increase awareness about CRC risk and screening and prompted participants to ask questions, and to want to learn more about what they could do to lower their risk. Messages that were viewed as humorous, strange or offensive or that had a negative or excessively fearful tone were less well received by study participants.

Conclusions

Facebook users prefer social media messages for CRC that have a positive or reassuring tone, are educational, and that have a credible ad sponsor. Campaign planners should proceed with caution when considering messages that use humor or a fearful tone to avoid undermining their campaign objectives.

Application of motivational interviewing strategies with the extended parallel process model to improve risk communication for parents of children with familial hypercholesterolemia

Current genetic counseling practice has not been found to significantly increase risk communication between family members. A more diverse set of genetic counseling approaches may be needed. A genetic counseling intervention based on motivational interviewing principles and the extended parallel process model was utilized to increase cascade outcomes within families with familial hypercholesterolemia, a common, underdiagnosed, and treatable condition. Parents of children with familial hypercholesterolemia were invited to participate in an online pre-survey, single-session genetic counseling intervention, and post-intervention surveys as a part of the CHEERS (Cholesterol Evaluation to Explore Risk Screening) intervention. This study investigated the efficacy of a genetic counselor delivered motivational interviewing intervention and how parents of children with familial hypercholesterolemia react by assessing family member cholesterol screening and risk communication to at-risk relatives. Transcripts were audio-recorded, transcribed, and analyzed for change talk using the Motivational Interviewing Skill Code version 2.1. Participant surveys were analyzed for self-reported extended parallel process constructs and motivations. Coincidence analysis was conducted to explore differences between those with and without positive cascade outcomes within 12 months after the intervention. On average, change talk increased during the session in order of the extended parallel process constructs (perceived severity, susceptibility, response efficacy, self-efficacy). Coincidence analysis revealed that 6 of the 7 cases with positive cascade outcomes were explained by either the presence of high change talk during the intervention or presence of positive motivations shortly after, while 5 of the 5 cases without a positive outcome lacked both of these key factors that were associated with cascade outcomes. Results of this study suggest that incorporating motivational interviewing and the extended parallel process model increases change talk and that the presence of either high levels of change talk or positive motivations is associated with positive cascade outcomes.

Extended parallel process model (EPPM) in evaluating lung Cancer risk perception among older smokers

Background

There is a lack of scientific literature on the application of fear appeals theories to evaluate lung cancer risk perception among smokers. The aim of the present study is to apply the Extended Parallel Process Model (EPPM) to discover the perception of the smokers about their lifetime risk of developing lung cancer (perceived susceptibility), their perception of lung cancer survival (perceived severity), response efficacy, self-efficacy, and readiness to quit.

Methods

In this cross-sectional study, 215 eligible smokers (aged 45 years and over who have smoked at least 1 pack per day in the last 5 years) were recruited. The data collection tool was designed using validate self-report questionnaires and it was contained items on the perceived risk of a smoker contracting lung cancer and perceived lung cancer survival rate. It also had questions to measure the main constructs of the EPPM and Readiness to quit (“Low_Readiness”, and “High_Readiness”). To test how the data support conceptual EPPM to data, Generalized Structural Equation Modeling (GSEM) was used.

Results

Findings showed a significant relationship between Perceived_Susceptibility and Perceived_Response Efficacy; (B = 1.16, P < 0.001); between Perceived_Susceptibility and Perceived_Self Efficacy, (B = -0.93, P < 0.001), Perceived_Severity, and Perceived_Response Efficacy (B = 1.07, P < 0.001). There was also a significant relationship between Perceived_Threat and Perceived_Response Efficacy; between Perceived_Threat and Perceived_Self Efficacy. The relationship between High_Readiness and Perceived_Self Efficacy, and between High_Readiness and Perceived_Severity also were significant. However, the relationships between High_Readiness and Perceived_Threat were not significant (P > 0.05).

Conclusion

Perceived_threat and Perceived_efficacy were important for smokers with low readiness to quit, while Perceived_efficacy was most important for smokers with high readiness to quit. These findings could be used in promoting lung cancer awareness and designing smoking cessation programs based on smokers’ stages of change.

Perceived Threats toward Esophageal Cancer among Immediate Relatives of Sufferers: a Qualitative Study

PURPOSE

Considering life-threatening nature of cancer and the problems that it causes for patients and families, recognizing their perspectives toward this issue is important. Therefore, the aim of this study was to determine perceived threats by immediate relatives of patients with esophageal cancer.

METHODS

Using content analysis approach, the present qualitative study was conducted in Golestan Province (north of Iran) in 2018. Through purposive sampling, 23 immediate relatives of patients with esophageal cancer were included in the study. The research techniques included semi-structured and deep interviews. We continued data collection to ensure data saturation was achieved. All interviews were recorded, transcribed, and then analyzed with Graneheim and Lundman's approach of conventional content analysis. The MAXQDA 11 software was applied to conduct the coding process.

RESULTS

Following data analysis, two main categories including "perceived susceptibility" and "perceived severity" were identified for perceived threats. The main category of "perceived susceptibility" comprised of four subcategory, namely, perception of individual, environmental, psychological, and nutritional predisposing factors to the disease. Four subcategories were also extracted for the "perceived severity," including perception of physical, psychological, therapeutic, and social consequences of the disease.

CONCLUSIONS

Immediate relatives of patients with esophagus cancer perceived high severity and susceptibility toward this disease and considered themselves vulnerable to this disease. Hence, they suffered from a lot of psychological stress. Development of appropriate interventions regarding the effects of disease-related individual and environmental factors and empowerment of individuals with regard to preventive disease behaviors can be an important step for improving the health of this group.

Outcomes from a pilot genetic counseling intervention using motivational interviewing and the extended parallel process model to increase cascade cholesterol screening

Familial hypercholesterolemia (FH) is an inherited condition resulting in increased risk of premature cardiovascular disease. This risk can be reduced with early diagnosis and treatment, but it can be challenging to identify individuals with FH. Cascade screening, the most efficient and cost-effective identification method, requires FH patients to communicate with their at-risk family and encourage them to pursue screening. Beyond FH, patients with conditions increasing disease risk to family members report barriers to the communication process such as insufficient knowledge of the condition and discomfort informing relatives. We conducted a pilot study of a genetic counseling intervention incorporating behavior-change principles from motivational interviewing (MI) and the extended parallel process model (EPPM) to help parents of children with FH overcome these barriers and improve cascade screening rates for FH. Of the 13 participants who completed the intervention and post-intervention surveys, 6 reported contacting and/or screening additional relatives. A large effect size in increasing communication and screening was observed (η²  = 0.20), with the mean percent of at-risk relatives contacted rising from 33% to 45%, and the mean percent screened rising from 32% to 42%. On average, 2.23 new relatives were contacted and 2.46 were screened, per participant, by the end of the study. Direct content analysis revealed that despite the open-ended nature of the goal-setting process, participant goals fell into two categories including those who set goals focused on communicating with and screening family members (n = 9) and those who set goals only focused on managing FH (n = 4). Overall, the communication and screening rates reported after the intervention were higher than previous observations in adult FH populations. These results suggest this EPPM/MI genetic counseling intervention could be a useful tool for increasing communication and cascade screening for FH. With further research on goal-setting techniques, the intervention could be refined and replicated to identify more individuals affected by FH or modified for use with other actionable genetic conditions.

Internet-based Tailored Virtual Human Health Intervention to Promote Colorectal Cancer Screening: Design Guidelines from Two User Studies

To influence user behaviors, Internet-based virtual humans (VH) have been used to deliver health interventions. However, Internet-based VH health interventions face challenges. The challenges can affect user perceptions of an Internet-based VH health intervention. In our work, we use an Internet-based VH health intervention to promote colorectal cancer (CRC) screening. We present design guidelines drawn from two studies. The two studies examined the influence of visual design and the influence of the information medium on user intentions to pursue more health information. In the first study, the analysis of the focus group (n=73 users) transcripts shows that the VH's visual realism, the VH's healthcare role, and the presence of a local healthcare provider's logo influenced user perceptions of the VH-based intervention's visual design. The findings from the focus groups were used to iterate the intervention and derive design guidelines. In the second study (n=1,400), the analysis of online surveys of users after the VH-based intervention showed that very few users focused on the VH's appearance. To influence the user intentions to pursue the health topic further, the results recommend the use of an animated VH to deliver health information compared to other mediums of information delivery, such as text. The design guidelines from the two studies can be used by developers to use VH-based interventions to influence users' intention to change behaviors.

The Effects of Perceived Threat and Efficacy on College Students' Social Distancing Behavior during the COVID-19 Pandemic

This study was conducted to determine the impact of perceived threat and efficacy on college students' social-distancing behavior during COVID-19 pandemic. Guided by the extended parallel process model (EPPM), this longitudinal study included 164 participants who completed a survey at two points in time. Results were consistent with previous theory and research for all danger control hypotheses (i.e., perceived threat predicted fear, fear and self-efficacy predicted intention, and intention predicted future behavior). For fear control, however, results were inconsistent with EPPM predictions, but consistent with previous research (i.e., fear was either unrelated or inversely related to fear control, and efficacy was inversely related to fear control). Overall, the EPPM constructs explained 69% of the variance in intention, 64% of the variance in behavior, 55% of the variance in defensive avoidance, and 20% of the variance in message derogation. The theoretical and practical insights and implications of these findings are discussed.

Concerns and Fear of Esophageal Cancer in Relatives of Patients with Cancer: a Qualitative Study

INTRODUCTION

Due to its complications and mortality, cancer is a vital public health problem and one of the most frightening diseases, and its development causes a sense of risk, problems, and discomforts for all, including family of patients. The aim of this study was to elaborate on the concerns and fear of esophageal cancer in relatives with cancer illness.

METHODS

Using a content analysis approach, this qualitative study was carried out in Golestan, North of Iran, in 2018. Participants were one of the family members of a patient with esophageal cancer who were selected purposefully. Data were collected using semi-structured and deep interviews and continued until data saturation was achieved. Twenty-three participants were interviewed. Interviews were transcribed line by line and were coded and categorized, and concepts were extracted accordance with qualitative content analysis approach, using MAXQDA 11 software.

RESULT

Following data analysis on the concerns and fear of cancer among relatives of patients, the main themes "fear of social consequences," "fear of treatment consequences," "fear of psychological consequences," "cancer phobia," "concern about lack of information on the disease," "fear of disease reactions," and "fear of disease-related changes" were extracted.

CONCLUSIONS

Family of patients with esophageal cancer were afraid of disease-induced consequences and lack of knowledge about the disease. Through educating people about the symptoms of the disease, we can reduce their fears and empower them for self-caring and preventing cancer.

Psychological predictors of intention and avoidance of attending organized mammography screening in Norway: applying the Extended Parallel Process Model

Background

Mammography screening is the main method for early detection of breast cancer in Norway. Few studies have focused on psychological determinants of both attendance and non-attendance of publicly available mammography screening programs. The aim of the current study, guided by the Extended Parallel Process Model, was to examine how psychological factors influence defensive avoidance of breast cancer screening and intention to attend mammography.

Methods

Cross-sectional survey data from a community sample of women living in Norway aged ≥ 18 (N = 270), and without a history of breast cancer, was collected from September 2018 to June 2019 and used to investigate the relationships between the Extended Parallel Process Model (EPPM) constructs and two outcomes: defensive avoidance of breast cancer screening and intention to attend mammography within the next two years. After adjusting for confounding factors, the hierarchical multiple linear regression analyses was conducted to assess the ability of the independent variables based on the EPPM to predict the two outcome variables. Significance level was chosen at p < 0.05.

Results

Multivariate analyses showed that defensive avoidance of breast cancer screening was predicted by lower perceived susceptibility to breast cancer (β =  − 0.22, p = 0.001), lower response efficacy of mammography screening (β =  − 0.33, p = 0.001), higher breast cancer fear (β = 0.15, p = 0.014), and checking breasts for lumps (β =  − 0.23, p = 0.001). Intention to attend mammography within the next two years was predicted by higher response efficacy of mammography screening (β = 0.13, p = 0.032), having a lower educational level (β =  − 0.10, p = 0.041), and regular previous mammography attendance compared to never attending (β = 0.49, p = 0.001).

Conclusions

The study revealed that defensive avoidance of breast cancer screening and intention to attend mammography were not predicted by the same pattern of psychological factors. Our findings suggest future health promotion campaigns need to focus not only on the psychological factors that encourage women’s decision to attend the screening, but also to counter factors that contribute to women’s decision to avoid it.

Lung Cancer Risk Perception Among Older Smokers; a Cross-sectional Study

Background: Lung cancer is one of the deadliest cancers around the world. Also, scientific evidence proves the considerably lower lung cancer risk perceptions of smokers compared to non-smokers. Objectives: This study aimed at assessing the risk perception of smokers about their risk to contract lung cancer and their perceptions about lung cancer survival. Methods: In this cross-sectional study, the data were collected from 215 smokers in Tabriz, Iran, between April 2019 and July 2019. The data collection tool was designed, using validated questionnaires and contained questions on the perceived risk of smokers to develop lung cancer and their perception of lung cancer survival. A general linear model was conducted to model the relationship of risk perception with underlying predictors considering a significance level of 0.1. Results: The results of modeling indicated that perceived susceptibility (P-Sus) was negatively related to “years smoked” in simple regression (B = -0.035, P = 0.069) and multiple regression (B = -0.069, P = 0.007). P-Sus was also negatively related to the variable “age” in the age category of 45 to 50 years (B = -1.981, P = 0.046). Moreover, perceived severity (P-Sev) was negatively related to the variable “sex” (B = -1.037, P = 0.068). The results of the Spearman correlation indicated significant and direct correlations between “quitting intention” and P-Sus (r = 0.296, P < 0.001), P-Sev (r = 0.162, P = 0.009). Conclusions: Lung cancer risk perception of participants was moderately above the average and significant correlations were observed between “quitting intention” and “P-Sus” and “P-Sev” and “Risk Perception score”. This could be utilized in developing educational programs to promote awareness about lung cancer, especially for smokers.

Is it disgusting or am I just easily disgusted? The relation between situational disgust, dispositional disgust, and colonoscopy intentions

OBJECTIVE

While early detection is an effective way to reduce mortality from colorectal cancer, screening rates are low. An underlying factor in screening completion failure may be experiences of disgust when learning about screening and/or dispositional disgust.

METHOD

Participants recruited via Amazon MTurk (N = 296) read information about colonoscopy and completed an online survey assessing both dispositional forms of disgust (i.e. trait disgust and disgust sensitivity) and situational forms, including state disgust and disgust associated with colonoscopy. Participants reported intentions to discuss colonoscopy with a provider and to prepare for and complete screening.

RESULTS

Greater state disgust and the degree to which one associated disgust with colonoscopy predicted lower screening, preparation and provider discussion intentions. By contrast, neither trait disgust nor disgust sensitivity was associated with intentions. Both disgust sensitivity and trait disgust moderated the state disgust to intentions relation.

CONCLUSIONS

This is one of few investigations of disgust examining the relation between specific types and colonoscopy intentions. Screening uptake may be improved by identifying specific components of disgust that have an effect on colonoscopy intentions. Future work focusing on the interplay between different disgust mechanisms as they relate to colonoscopy behaviour is important for intervention development.

Prevention behaviours of oesophageal cancer: Protocol for a mixed-method study

AIM

The aim was to implement an educational programme for the family members of patients with oesophageal cancer on prevention behaviours in Golestan province, north of Iran.

DESIGN

In this mixed-method research, qualitative and quantitative studies will be conducted.

METHODS

This study will be carried out using an exploratory mixed-method design in Golestan province, north of Iran in 2018-2019. The research will include three consecutive phases. At first, a qualitative study will be carried out to determine the preventive behaviour and measures of oesophageal cancer. In this phase, the participants will be selected using the purposive sampling method. Later, semi-structured interviews will be conducted with the relatives of patients with oesophageal cancer to collect the necessary qualitative data. The second phase will include a literature review based on the information collected from the first phase. Later, a researcher-made questionnaire will be designed based on the extended parallel process model. Furthermore, a comprehensive programme will be proposed about self-care of the patients with oesophageal cancer. In the third phase, a quantitative quasi-experimental research will be conducted over two groups of participants to measure the effectiveness of this programme. This research was approved by the Ethics Committee of Yazd Shahid Sadoughi University of Medical Sciences, Iran in November 2017.

DISCUSSION

Educational interventions should be designed purposefully according to the needs of the target group to improve their self-care behaviours. We also expect that this research can improve the individuals' access to high-quality preventive behaviours with regard to oesophageal cancer.

TRIAL REGISTRATION

The project was registered on the Iranian Registry of Clinical Trials, (registration number: IRCT20180725040588N1, date registered: 2th October 2018).

Do ultraviolet photos increase sun safe behavior expectations via fear? A randomized controlled trial in a sample of U.S. adults

Ultraviolet (UV) photos reveal the world in a different light spectrum, including damage that is caused by UV light. In the context of skin cancer control, UV photos have the potential to communicate fear because they reveal underlying skin damage. U.S. adults (N = 2219) were assigned to a 5 (visual: UV skin damage, sun exposure, sunburn, photoaging, and mole removal) × 3 (replication: three examples of each visual condition) × 4 (efficacy: no efficacy, text only, visual, visual + text) randomized controlled trial. Compared to all other visual conditions combined, UV skin damage visuals generated greater fear which triggered increased sun safe behavior expectations. Compared with other visual conditions separately, only mole removal visuals produced equivalent fear as UV skin damage visuals. Visual efficacy conditions appeared to nullify rather than magnify the indirect path through fear. The results suggest one way UV images impact sun safe behavioral expectations is via fear and that researchers should continue to examine the position of fear in fear appeal theories.

Benzodiazepine use risk: Understanding patient specific risk perceptions and medication beliefs

BACKGROUND

Benzodiazepines are widely prescribed psychotropic medications. These medications have the potential to cause alertness impairing effects and their prolonged use is associated with serious adverse effects. Despite the listed adverse health outcomes and provision of warnings, many benzodiazepine users tend to ignore the safety information and use them inappropriately.

OBJECTIVE

To elicit the risk perceptions of benzodiazepine users and explore the association of risk perceptions with their socio-demographic factors or medication use profiles (e.g. past withdrawal attempt, length of use and future willingness to try behavioural alternatives).

METHODS

Point of purchase surveys were conducted with patients who were supplied benzodiazepines from selected pharmacies across New South Wales (NSW), Australia. Survey items included questions about patient's demographic characteristics, their past attempt for withdrawing benzodiazepines and their future intention to consider alternative behavioural therapies. The validated Beliefs about Medications Questionnaire (BMQ-specific) and a customised scale assessing risk perception were included in the survey. Data obtained from the surveys were entered into the IBM SPSS package (Version 22.0) and subjected to descriptive, correlational and regression analyses.

RESULTS

Seventy-five patients (67% female, a mean age of 54.3) obtaining benzodiazepines from 12 pharmacies were recruited for the survey. Participant's beliefs regarding potential side effects of benzodiazepines and their level of education were significantly associated with their risk perception scores. While the overall risk perception scores did not influence patient's previous attempts to withdraw benzodiazepines, the risk perception score about immediate effects of benzodiazepines (within 3-4 h of consumption) was a predictor of preference for behavioural therapies. Eighty-three percent (n = 62) of the participants believed that pharmacists can play a key role in improving risk perceptions of consumers around benzodiazepine use.

CONCLUSIONS

Individual patient characteristics and their beliefs about medications significantly influence their perception of risk about benzodiazepine use. The findings of this study suggest that pharmacist support can be utilized in effective risk communication, promoting the safe use of benzodiazepines and in facilitating the uptake of relevant behavioural interventions as alternatives to benzodiazepines.

Promoting guideline-based cancer genetic risk assessment for hereditary breast and ovarian cancer in ethnically and geographically diverse cancer survivors: Rationale and design of a 3-arm randomized controlled trial

BACKGROUND

Although national guidelines for cancer genetic risk assessment (CGRA) for hereditary breast and ovarian cancer (HBOC) have been available for over two decades, less than half of high-risk women have accessed these services, especially underserved minority and rural populations. Identification of high-risk individuals is crucial for cancer survivors and their families to benefit from biomedical advances in cancer prevention, early detection, and treatment.

METHODS

This paper describes community-engaged formative research and the protocol of the ongoing randomized 3-arm controlled Genetic Risk Assessment for Cancer Education and Empowerment (GRACE) trial. Ethnically and geographically diverse breast and ovarian cancer survivors at increased risk for hereditary cancer predisposition who have not had a CGRA are recruited through the three statewide cancer registries. The specific aims are to: 1) compare the effectiveness of a targeted intervention (TP) vs. a tailored counseling and navigation(TCN) intervention vs. usual care (UC) on CGRA utilization at 6 months post-diagnosis (primary outcome); compare the effectiveness of the interventions on genetic counseling uptake at 12 months after removal of cost barriers (secondary outcome); 2) examine potential underlying theoretical mediating and moderating mechanisms; and 3) conduct a cost evaluation to guide dissemination strategies.

DISCUSSION

The ongoing GRACE trial addresses an important translational gap by developing and implementing evidence-based strategies to promote guideline-based care and reduce disparities in CGRA utilization among ethnically and geographically diverse women. If effective, these interventions have the potential to reach a large number of high-risk families and reduce disparities through broad dissemination.

Intervention Mediators in a Randomized Controlled Trial to Increase Colonoscopy Uptake Among Individuals at Increased Risk of Familial Colorectal Cancer

BACKGROUND

Understanding the pathways by which interventions achieve behavioral change is important for optimizing intervention strategies.

PURPOSE

We examined mediators of behavior change in a tailored-risk communication intervention that increased guideline-based colorectal cancer screening among individuals at increased familial risk.

METHODS

Participants at increased familial risk for colorectal cancer (N = 481) were randomized to one of two arms: (1) a remote, tailored-risk communication intervention (Tele-Cancer Risk Assessment and Evaluation (TeleCARE)) or (2) a mailed educational brochure intervention.

RESULTS

Structural equation modeling showed that participants in TeleCARE were more likely to get a colonoscopy. The effect was partially mediated through perceived threat (β = 0.12, p < 0.05), efficacy beliefs (β = 0.12, p < 0.05), emotions (β = 0.22, p < 0.001), and behavioral intentions (β = 0.24, p < 0.001). Model fit was very good: comparative fit index = 0.95, root-mean-square error of approximation = 0.05, and standardized root-mean-square residual = 0.08.

CONCLUSION

Evaluating mediating variables between an intervention (TeleCARE) and a primary outcome (colonoscopy) contributes to our understanding of underlying mechanisms that lead to health behavior change, thus leading to better informed and designed future interventions.

Care delivery considerations for widespread and equitable implementation of inherited cancer predisposition testing

INTRODUCTION

DNA sequencing advances through next-generation sequencing (NGS) and several practice changing events, have led to shifting paradigms for inherited cancer predisposition testing. These changes necessitated a means by which to maximize health benefits without unnecessarily inflating healthcare costs and exacerbating health disparities. Areas covered: NGS-based tests encompass multi-gene panel tests, whole exome sequencing, and whole genome sequencing, all of which test for multiple genes simultaneously, compared to prior sequencing practices through which testing was performed sequentially for one or two genes. Taking an ecological approach, this article synthesizes the current literature to consider the broad impact of these advances from the individual patient-, interpersonal-, organizational-, community- and policy-levels. Furthermore, the authors describe how multi-level factors that impact genetic testing and follow-up care reveal great potential to widen existing health disparities if these issues are not addressed. Expert commentary: As we consider ways to maximize patient benefit from testing in a cost effective manner, it is important to consider perspectives from multiple levels. This information is needed to guide the development of interventions such that the promise of genomic testing may be realized by all populations, regardless of race, ethnicity and ability to pay.

Reinforcing the role of psycho-social oncology in global cancer prevention: applying psycho-oncology research in programmes and practice

Over the past decade, global action to address the emerging crisis in non-communicable diseases (NCDs) has escalated. Central to these efforts has been the support and influence of the World Health Organisation and the United Nations with the 2000 civil societies represented by the Non-Communicable Disease Alliance. In particular this reached expression in the world's first High Level Meeting on NCDs by the United Nations leading to the 2011 Political Declaration urging a coordinated global response to NCDs. Where then does psycho-oncology sit in this global context? Psycho-oncology practitioners and their collective, the International Psycho-Oncology Society (IPOS), have traditionally been situated within a patient focus and context. However, through linkages with community-based and non-government cancer organisations' agencies, psycho-oncology research and practice has played a key role in reducing cancer risk, improving cancer survivorship, and influencing social and cultural change to eliminate disease-related stigma. As a discipline, psycho-oncology has contributed to widespread recognition of patient-centred care in cancer and along with a broad acceptance and endorsement of the IPOS International Standard. However psycho-oncology is less well accepted in nation-state cancer plans and herein lies opportunity. This special issue includes research across the illness continuum from cancer prevention to screening and early detection, and then to tertiary prevention with lifestyle considerations for cancer survivors. Importantly this demonstrates the capacity within psycho-oncology to develop new understandings of cancer as not only a disease but also a context linked to individual, community, and society health and well-being.
