RESUMO

BACKGROUND: Communication inequalities are important mechanisms linking socioeconomic backgrounds to health outcomes. Guided by the structural influence model of communication, this study examined the intermediate role of health communication in the relationship between education, income, and preventive behavioral intentions during the COVID-19 pandemic in the United States and South Korea. METHODS: The data were collected through two online surveys conducted by two professional research firms in the US (April 1-3, 2020) and South Korea (April 9-16, 2020). To test the mediating role of health communication, as well as the hypothesized relationships in the proposed model, we performed a path analysis using Mplus 6.1. RESULTS: In analyzing survey data from 1050 American and 1175 Korean adults, we found that one's socioeconomic positions were associated with their intentions to engage in COVID-19 preventive behaviors through affecting their health communication experiences and then efficacious beliefs. Differences in education and income were associated with willingness to engage in preventive behaviors by constraining health communication among people with low levels of education and income. The findings showed notable differences and some similarities between the US and South Korea. For example, while income was positively associated with health communication in both US and South Korea, education was only significantly related to health communication in US but not in South Korea. CONCLUSIONS: This study suggests health communication strategies such as choice of communication channels and messages to promote intention for COVID-19 prevention behaviors in particular consideration of individual differences in socioeconomic positions in countries with different cultural features. Pubic policies and health campaigns can utilize the suggestions to promote efficacy and preventive behavioral intention during early pandemics.

RESUMO

The purpose of this study is to build a theoretical framework to account for how social media lead college students to smoke. Arguing critical concepts, such as valence of communication, impression management, perceived risks and benefits, this study develops the O 1 -S-R 1 -O 2 -R 2 model. For this, we test a separated model for smokers and nonsmokers. For smokers, the effect of exposure to pro-smoking content on smoking behavior is mediated by an impression of smokers, a favorable expression about smoking, and perceived benefits. And, the effect of exposure to anti-smoking content on smoking behavior is mediated by an unfavorable expression about smoking and perceived risks. However, such mediation processes cannot be observed for nonsmokers; namely, the effect of exposure to pro-smoking content on smoking intention is only mediated by a favorable expression about smoking. Considering the separated path models for smokers and nonsmokers, theoretical and practical implications are suggested for future study. Methodological limitations are discussed as well.

RESUMO

Social media have become increasingly important in risk and crisis situations. However, little is known about which types of social media have greater influence on risk perceptions and behaviors. This study pursues two goals related to this question. The first is to explicate the cognitive mechanism underlying the process through which exposure to risk information on social media shapes people's behavioral intentions. The second is to determine whether exposures to risk information on two different types of social media-content-oriented social media focusing on shared interests versus user-oriented social media focusing on social relationships-have different effects on people's risk perceptions and behavioral intentions. Analyzing survey data from 688 adults from the general population of South Korea in the context of carcinogenic hazards, we found that self-reported content-oriented social media exposure (to risk information) was significantly related to both personal-level and societal-level risk perceptions. In addition, content-oriented social media exposure was associated with behavioral intentions indirectly through risk perceptions. However, user-oriented social media exposure had no impact on risk perceptions and behavioral intentions, either directly or indirectly through risk perceptions.

RESUMO

Despite the importance of social network sites (SNSs) in addressing emerging public health risks, there is still a relative lack of studies examining the effects of risk communication via SNSs on risk perceptions and preventive behaviors. Based on message expression‒ and reception‒effects paradigms, this study aims to explore how expressing and receiving risk information shape preventive behavioral intentions via risk perceptions. Given the differential nature and functionality of SNSs, the present investigation also examines whether expressing and receiving risk information via two different types of SNSs-Facebook and Twitter-have different effects on risk perceptions and behavioral intentions. Analyzing survey data from 1,152 South Korean adults in the context of fine dust hazards, this study found that expressing and receiving risk information not only affected risk perceptions but also directly or indirectly influenced preventive behavioral intentions. In addition, the effects of expressing and receiving risk information were differentiated between SNS platforms, specifically Facebook and Twitter.

RESUMO

This study investigated the role of breast cancer survivors in a computer-mediated social support (CMSS) group for women with breast cancer. Applying a computer-aided content analytic method, the present study examined the differences in support provision between survivors and newly diagnosed patients. This study further investigated the impacts of survivor-provided social support on psychosocial adjustment of newly diagnosed patients. The results revealed that, compared with newly diagnosed patients, breast cancer survivors provided more emotional and informational support. Receiving emotional support from survivors contributed to an improvement in the quality of life and the depression of patients. The effects of survivor-provided informational support were not significant.

RESUMO

The growth of online support groups has led to an expression effects paradigm within the health communication literature. Although religious support expression is characterized as a typical subdimension of emotional support, we argue that in the context of a life-threatening illness, the inclusion of a religious component creates a unique communication process. Using data from an online group for women with breast cancer, we test a theoretical expression effects model. Results demonstrate that for breast cancer patients, religious support expression has distinct effects from general emotional support messages, which highlights the need to further theorize expression effects along these lines.

RESUMO

BACKGROUND: With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient-clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. MATERIALS AND METHODS: We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. RESULTS: Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. CONCLUSIONS: Mobile texting messaging has the potential to play an important role in patient-clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication.

RESUMO

Despite the importance of family environment and computer-mediated social support (CMSS) for women with breast cancer, little is known about the interplay of these sources of care and assistance on patients' coping strategies. To understand this relation, the authors examined the effect of family environment as a predictor of the use of CMSS groups as well as a moderator of the relation between group participation and forms of coping. Data were collected from 111 patients in CMSS groups in the Comprehensive Health Enhancement Support System "Living with Breast Cancer" intervention. Results indicate that family environment plays a crucial role in (a) predicting breast cancer patient's participation in CMSS groups and (b) moderating the effects of use of CMSS groups on breast cancer patients' coping strategies such as problem-focused coping and emotion-focused coping.

RESUMO

OBJECTIVE: This paper seeks to contribute to the understanding of how and why religion affects psychosocial health outcomes. We propose a theoretical model predicting that when women with breast cancer defer control to God they will experience fewer breast cancer related concerns. Deferring control to God, however, should also reduce the likelihood that they take a proactive coping approach, which will be exacerbated by lowered breast cancer concerns. We therefore predict that this passive coping style will ultimately result in lower levels of quality of life. METHODS: Data were collected as part of a randomized clinical trial funded by the National Cancer Institute. A total of 192 women with breast cancer participated in a computer-mediated social support group. Deferring control to God statements were captured by using computer-aided content analysis of discussion posts. Psychosocial outcomes were measured using longitudinal survey data. Analysis was performed using structural equation modeling. RESULTS: The results of our analysis largely confirm our mediation model for which we find significant model fit. As predicted, deferring control to God leads to lower levels of breast cancer concerns but also to more passive coping styles. Ultimately, deferring control to God can lead to lower levels of quality of life. CONCLUSIONS: Our study demonstrates how and why religious coping can lead to both positive and negative psychosocial health outcomes. Health care practitioners should encourage patients who are relying on religion to keep their end of the bargain and maintain an active coping style.

RESUMO

Mobile health (mHealth) technologies may reduce or widen health inequalities. Despite the extensive literature in support of both of these contrasting views, little attention has been paid to the role of mHealth technologies with regard to social strata and health in the context of South Korea, a country with one of the highest usages of smartphones worldwide. This study examined the effects of social determinants on health self-efficacy and health status and explored how mHealth technologies moderate the impacts of social determinants on health outcomes. Data were collected via online surveys from 29 July to 3 August 2021. Survey data from 1187 Korean adults showed that men had higher levels of health self-efficacy than women. The higher an individual's education level, the greater their subjective health status. Individuals with higher levels of monthly household income, social capital, and healthcare quality reported higher levels of health self-efficacy and superior health status. The use of mHealth technologies moderated the associations between social determinants and health outcomes. Specifically, monthly household income and social capital had smaller effects on health self-efficacy and health status among those who used higher levels of mHealth technologies. Among higher users of mHealth technologies, females reported better health status than males, while men showed better health status than women in the low-user group. These findings highlight the effectiveness of mHealth technologies in addressing health disparities.

RESUMO

The purpose of this study was to investigate the nature and effects of exchanging emotional support via a smartphone-based support group for patients with alcohol dependence. Of the 349 patients who met the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for alcohol dependence, 153 patients participated in the discussion group within the Addiction-Comprehensive Health Enhancement Support System, a smartphone application aimed at reducing relapse. This was developed to prevent problem drinking by offering individuals in recovery for alcohol dependence automated 24/7 recovery support services and frequent assessment of their symptom status as part of their addiction care. The results showed that receiving emotional support from health care providers improved coping self-efficacy. Giving emotional support and receiving emotional support from health care providers acted as a buffer, protecting patients from the harmful effects of emotional distress on risky drinking. Clinicians and researchers should use the features of smartphone-based support groups to reach out to alcoholic patients in need and encourage them to participate in the exchange of emotional support with others.

RESUMO

Analyzing nationally representative online panel survey data during the MERS outbreak in South Korea, this study examined the role of social media exposure in shaping public's risk perceptions of MERS. The present study also investigated the moderating role of heuristic-systematic processing and self-efficacy in the relationship between social media exposure and risk perceptions. The findings of this study showed that social media exposure was positively related to forming risk perceptions. Moreover, heuristic-systematic processing and self-efficacy were found to moderate the impact of social media on risk perceptions. The interaction effects suggested that the role of social media in increasing risk perceptions of MERS was heighted by heuristic-systematic processing and self-efficacy. The results and implications of this study are discussed in greater details.

RESUMO

OBJECTIVE: This study examined the effect of celebrity smoking exemplars in health news on college students' perceptions of smoking-related health risks and smoking intentions. PARTICIPANTS AND METHODS: The data were collected using a Web-based survey of 219 undergraduate students at a large midwestern university in March 2011. Separate analyses of covariance were conducted. RESULTS: The influence of negative exemplars of celebrity smoking on perceptions of smoking-related health risks and smoking intentions varied according to smoking status. Ever-smokers who read smoking news with negative exemplars of celebrity smoking were more likely than ever-smokers who read the same news absent any exemplar to report higher levels of perceptions of smoking-related health risks and lower levels of smoking intentions. However, these patterns were not found in never-smokers. CONCLUSIONS: Exemplification theory enhanced by the celebrity element may be effectively applied as a strategy to change health behavior in college students.

RESUMO

Building on the influence of presumed influence (IPI) model, this study examines how smoking- related messages on social media influence college students' smoking. We surveyed 366 college students from three U.S. Midwestern universities in 2012 and examined the effects of expression and reception of smoking-related messages on smoking using path analysis. We found that the expression and reception of prosmoking messages not only directly affected smoking but also had indirect effects on smoking through (1) perceived peer expression of prosmoking messages and (2) perceived peer smoking norms. For antismoking messages, only reception had a significant indirect influence on smoking through (1) perceived peer reception of antismoking messages and (2) perceived peer smoking norms. In conclusion, social media function as an effective communication channel for generating, sharing, receiving, and commenting on smoking-related content and are thus influential on college students' smoking.

RESUMO

Individuals use social network sites (SNSs) as an effective tool for communicating relevant information with others during the outbreak of infectious diseases. However, little is known about the underlying mechanism through which communicative behaviors influence preventive behaviors. Thus, in the context of Middle East respiratory syndrome (MERS) in South Korea, this study investigated how two communicative behaviors (message expression and reception) in SNSs affected the communicators' intentions to engage in MERS-preventive behaviors. Using data collected from a nationally representative panel survey of 1000 Korean adults aged 19 or older, we examined a theoretical expression and reception effects model. Results support the presence of effects from expressing and receiving MERS-related information via SNSs and their underlying mechanism during South Korea's MERS outbreak. Public health officials and communication professionals should actively use SNS communication in coping with public health crisis caused by emerging infectious diseases.

RESUMO

This study examines the moderating role of emotional communication competence in the relationship between computer-mediated social support (CMSS) group participation, specifically giving and receiving emotional support, and psychological health outcomes. Data were collected as part of randomized clinical trials for women diagnosed with breast cancer within the last 2 months. Expression and reception of emotional support was assessed by tracking and coding the 18,064 messages that 236 patients posted and read in CMSS groups. The final data used in the analysis was created by merging (a) computer-aided content analysis of discussion posts, (b) action log data analysis of system usage, and (c) baseline and six-month surveys collected to assess change. Results of this study demonstrate that emotional communication competence moderates the effects of expression and reception of emotional support on psychological quality of life and breast cancer-related concerns in both desired and undesired ways. Giving and receiving emotional support in CMSS groups has positive effects on emotional well-being for breast cancer patients with higher emotional communication, while the same exchanges have detrimental impacts on emotional well-being for those with lower emotional communication competence. The theoretical and practical implications for future research are discussed.

RESUMO

OBJECTIVES: To explore how the expression of emotional support in an online breast cancer support group changes over time, and what factors predict this pattern of change. METHODS: We conducted growth curve modeling with data collected from 192 participants in an online breast cancer support group within the Comprehensive Health Enhancement Support System (CHESS) during a 24-week intervention period. RESULTS: Individual expression of emotional support tends to increase over time for the first 12 weeks of the intervention, but then decrease slightly with time after that. In addition, we found that age, living situation, comfort level with computer and the Internet, coping strategies were important factors in predicting the changing pattern of expressing emotional support. CONCLUSIONS: Expressing emotional support changed in a quadratic trajectory, with a range of factors predicting the changing pattern of expression. PRACTICAL IMPLICATIONS: These results can provide important information for e-health researchers and physicians in determining the benefits individuals can gain from participation in should CMSS groups as the purpose of cancer treatment.

RESUMO

BACKGROUND: Emotional support has traditionally been conceived as something a breast cancer patient receives. However, this framework may obscure a more complex process, facilitated by the emerging social media environment, which includes the effects of composing and sending messages to others. Accordingly, this study explores the effects of expression and reception of emotional support messages in online groups and the importance of bonding as a mediator influencing the coping strategies of breast cancer patients. METHODS: Data were collected as part of two National Cancer Institute-funded randomized clinical trials. Eligible subjects were within 2 months of diagnosis of primary breast cancer or recurrence. Expression and reception of emotionally supportive messages were tracked and coded for 237 breast cancer patients. Analysis resulted from merging 1) computer-aided content analysis of discussion posts, 2) action log analysis of system use, and 3) longitudinal survey data. RESULTS: As expected, perceived bonding was positively related to all four coping strategies (active coping: ß = 0.251, P = .000; positive reframing: ß = 0.288, P = .000; planning: ß = 0.213, P = .006; humor: ß = 0.159, P = .009). More importantly, expression (γ = 0.138, P = .027), but not reception (γ = -0.018, P = .741), of emotional support increases perceived bonding, which in turn mediates the effects on patients' positive coping strategies. CONCLUSIONS: There is increasing importance for scholars to distinguish the effects of expression from reception to understand the processes involved in producing psychosocial benefits. This study shows that emotional support is more than something cancer patients receive; it is part of an active, complex process that can be facilitated by social media.

RESUMO

OBJECTIVES: To examine the effects of exchanging treatment information within computer-mediated breast cancer support groups on emotional well-being, and to explore whether this relationship is moderated by health self-efficacy. SAMPLE: 177 breast cancer patients using an electronic Health (eHealth) program with discussion group. MEASURE: expression and reception of treatment information; emotional well-being scale (0, 4 months). ANALYSES: hierarchical regression. RESULTS: Effects of expression and reception of treatment information on emotional well-being were significantly greater for those who have higher health self-efficacy. CONCLUSIONS: Results conditionally support prior research finding positive effects of treatment information exchanges among breast cancer patients. Such exchanges had a positive impact on emotional well-being for those with higher health self-efficacy, but they had a negative influence for those with lower health self-efficacy. PRACTICE IMPLICATIONS: Given that the association between emotional well-being and exchanging treatment information was moderated by health self-efficacy, clinicians should explain the role of health self-efficacy before encouraging patients to use eHealth systems for treatment exchanges.
