This study tested the effects of normative influence on increasing college students' attitudes, intentions, and willingness to communicate about organ and tissue donation (OTD). It was hypothesized that students would look to their peers (referent group) in forming their own attitudes about organ donation. Three hundred thirty-nine (N = 339) participants were randomly assigned to one of five experimental conditions: (1) control group; (2) general referent/normative message group; (3) specific referent/normative message group; (4) general referent/counternormative message group; and (5) specific referent/counternormative message group. An interaction effect was predicted between message type (normative > counternormative) and attributed message source (specific referent > general referent). Students reported highly favorable attitudes toward OTD, moderate-to-high levels of intentions to become organ donors and willingness to communicate about OTD. The hypothesis that participants within the normative message condition would report more favorable attitudes, intentions, and willingness to communicate about OTD compared to participants within the counternormative message condition was supported for participants' willingness to communicate about OTD. The second hypothesis that participants within the specific referent condition would express more favorable attitudes, intentions, and willingness to communicate was rejected. 相似文献

The desperate need for organ donors in the United States could be filled if every person eligible became an organ donor. Unfortunately, few organ donation campaigns exist, and fewer still have been evaluated empirically. This study has two objectives: to describe a worksite organ donation campaign and test campaign effects, and to test the Model of Behavioral Willingness to Donate Organs. Results of the campaign evaluation demonstrate that the worksite campaign was successful in increasing knowledge, favorable attitudes toward organ donation, behavioral intent to sign an organ donor card, actual rates of signed organ donor cards, and the willingness to talk to family members about the decision to donate organs. Results of path analyses produced mixed results with regard to model testing. Implications of these findings are discussed. 相似文献

To date, African Americans and Latinos consent to organ donation at lower rates than Caucasians and are disproportionately represented on transplant waiting lists. However, limited work has investigated racial differences in predictors of organ donation registration. In this study, we examined racial differences in the antecedents of African American, Caucasian, and Latino young adults’ registration intentions using the theory of planned behavior, the noncognitive model, and perceived realism. Non-donors (N = 307) were recruited in a stratified random telephone survey. Results indicate that for African Americans, subjective norm, bodily integrity, and medical mistrust were the strongest predictors of registration intention. For Caucasians, attitude and subjective norm arose as key determinants of registration intention. For Latinos, attitude, subjective norm, and medical mistrust were the strongest predictors of registration intention. Consistent evidence for the independent predictive validity of perceived realism was also documented. The theoretical and practical implications of these findings are discussed, as well as avenues for future research. 相似文献

The present study expands on prior work on the use of narratives in persuasive communication by examining students’ (N = 201) reactions to six organ donation public service announcements (PSAs). Reactions to the type of appeal, donor-focused or recipient-focused, were also explored. Results indicated that being immersed in the PSA was positively associated with message reactions and negatively associated with threats to overall freedom of choice when deciding whether or not to become an organ donor. Those perceived threats partially mediated the relationship between immersion into the story of the PSA and message reactions, such that increased threats were associated with reduced message reactions. Individuals exposed to the recipient-focused appeals were more interested in the narrative of the PSAs than those exposed to donor-focused appeals. Results are discussed in the context of future message and campaign development. 相似文献

This study demonstrates how communication research can be strategically applied to address environmental problems in modern societies. To accomplish this goal, this research advances an integrated communication model based on psychological reactance theory and the theory of planned behavior to explain negative attitude change that can occur when people are exposed to water conservation campaigns [Liang, Y. J., Henderson, L.K., & Kee, K. F. (2017). Running out of water! Developing a message typology and evaluating message effects on attitude toward water conservation. Environmental Communication. doi:10.1080/17524032.2017.1288648]. The data fit the hypothesized model, synthesizing message-, social-, and individual-based processes to predict their effects on behavioral intention towards water conservation. Interestingly, data show that (1) combinations of message strategies affect reactance differently, and (2) subjective norm and perceived behavioral control negatively correlated with threat to freedom. These results point to the practical implication that environmental communication to promote voluntary water conservation are effective when campaign messages are designed to reduce threat to freedom, induce social norms, and increase self-efficacy. We call the documented research process strategic environmental communication, which focuses on the joint application of evidence and theory towards addressing environmentally motivated problems. 相似文献

Despite growing concern over the public’s fatigue toward inundated health messages, communication research has largely neglected such ramifications of prolonged, real-life campaign exposure. This paper offers an initial conceptual and empirical treatment of message fatigue, an important, but understudied, side effect of campaigns. Specifically, it proposes conceptual and operational definitions of the construct and examines psychometric characteristics of a proposed message fatigue scale. The findings from two studies concerning safe sex (N?=?412) and anti-obesity messages (N?=?396) demonstrated solid support for the scale’s unidimensionality. In support of construct validity, the scale exhibited significant associations with message avoidance, annoyance, information seeking, and desensitization. Moreover, in an experimental setting in Study 2, message fatigue negatively predicted attention and message elaboration, while positively predicting counterargument. 相似文献

This investigation examined whether persuasive organ donation messages that target individuals’ identification with a salient social group will be more effective in encouraging these individuals to become organ donors than will information-only persuasive messages. Participants were randomly assigned to view one of two pro-organ donation messages, both of which included basic information about organ donation (need, number of registered donors, etc.) while one also targeted social identity. Findings indicate that individuals exposed to a social identification message were more likely to click a link that allowed them to officially register as organ donors. These results offer support for the utility of social identification as a health communication campaign strategy for increasing organ donation. 相似文献

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers. 相似文献

Nonverbal expectancy violations theory holds that positive violations produce more favorable communication outcomes than conformity to expectations, while negative violations produce less favorable ones, and that reward characteristics of the communicator mediate the interpretation and evaluation of violations. The factors affecting expectancies and the consequences of violating them are reviewed and compared to other models (discrepancy‐arousal, arousal‐labeling, arousal‐valence, sequential functional) employing similar assumptions and mediating variables. An experiment extending the model domain to immediacy violations and to interactions with familiar as well as unfamiliar others had friend and stranger dyads (N=82) engage in discussions during which one member of each pair significantly increased immediacy, significantly reduced it, or conformed to normal levels. Nonimmedicacy violations produced lower credibility ratings than high immediacy or conformity to expectations for both friends and strangers. Nonimmediacy was interpreted as communicating detachment, nonintimacy, dissimilarity and more dominance than normal immediacy, while high immediacy expressed the most intimacy, similarity, involvement and dominance. Implications for the role of ambiguity in violations are discussed. 相似文献

This is a multiple methods study that highlights the tension between awareness- and behavioral-based campaign successes, particularly when communicating using social media and pop-culture-referencing humor. To illustrate, it examines the Centers for Disease Control and Prevention's (CDC) “zombie apocalypse” all-disaster-preparedness campaign. An interview with a CDC campaign manager, campaign document analysis, and a 2 (information form: social vs. traditional media) × 2 (message strategy: humorous vs. non-humorous) experiment uncovers benefits and pitfalls of using social media and humorous messaging for risk communication. Findings show social media can quickly spread information to new publics for minimal costs; however, experiment participants who received the humorous (i.e., zombie) risk message reported significantly weaker intentions to take protective actions in comparison to those who received the traditional, non-humorous risk message. 相似文献

This study predicted that variations in the content of a narrative organ donor appeal (i.e., the age of the donor, the age of the person whose life was saved, the donor's cause of death, and the number of people whose lives were saved) would have a differential impact on a person's affective and cognitive reactions to that message, which would in turn influence a person's attitude toward signing an organ donor card. Two hundred sixty-eight individuals who had not signed an organ donor card previously read one of several narratives and then answered a series of questions designed to measure their attitudes toward signing an organ donor card. These data revealed that how a person dies (accident vs natural causes) and the number of people who are saved through organ donation indirectly influence a person's attitude toward signing an organ donor card with vividness, sympathy, and happiness acting as mediating variables. These findings and their implications are discussed. 相似文献

Fear appeals have long been used in persuasive messages to motivate people to perform adaptive behaviors. This research explored the influence of a fear appeal message concerning breast cancer on attitude accessibility. Messages advocating the efficacy of breast self‐examinations increased the accessibility of attitudes toward the adaptive behavior. Further, the accessibility of participants' attitudes toward the adaptive behavior predicted behavioral intentions to perform breast self‐examinations. Attitudes toward the threat became less accessible after exposure to a high fear‐arousing message, however. Analyses suggest that defensive reactions to the fear‐inducing message mediate the influence of the message on the accessibility of the attitudes toward breast cancer. Implications of these findings for models of fear appeals are discussed. 相似文献

Examining the persuasive effect of statistical messages: A test of mediating relationships 总被引：1，自引：0，他引：1
The current study tested the degree to which the sample size heuristic (Baesler & Bur goon, 1994), perceived verifiability of evidence (Ah Yun & Massi, 2000), and perceived message credibility (Kopfman, Smith, Ah Yun, & Hodges, 1998) mediate the relationship between the use of statistical evidence in a persuasive appeal and a person's attitude toward a given topic. Four hundred eighty‐six participants were exposed to one of three messages (statistical, narrative, or no‐evidence control) or a no‐message control condition and completed either a 12‐ (control) or 33‐item (experimental) survey that was designed to measure respondents’ perceptions of the sample size heuristic, verifiability of evidence, message credibility, and attitude toward a year‐round academic schedule. Path analysis and hierarchical regression modeling were employed to test the proposed model. Results revealed that the perceived sample size heuristic, verifiability of evidence, and message credibility mediate the relationship between statistical evidence and individuals’ attitudes. Additionally, the perceived sample size heuristic was found to be the strongest unique predictor of attitudes and confirmatory factory analysis results indicated that perceived verifiability and message credibility may be two indicators of a higher‐order factor. These findings and their implications for future research are discussed. 相似文献

A random telephone survey (N=582) of Washington state voters conducted in November 1994 examines relationships among mass media use, specific aspects of political disaffection, political efficacy and participation. Results suggest that negativism toward media campaign coverage reduces media use and that cynicism toward the political system reduces political efficacy. Negativism and media use also are negatively related to cynicism. Contrary to concerns expressed by some scholars and journalists concerning the negative impact of superficial media coverage on political participation, however, mass media use positively predicts voting behavior. In addition, negativism toward campaign tactics appears unrelated to political participation. 相似文献

For some international students, teachers' nonverbal immediacy may constitute a violation of expectations in classroom behavior. Using Expectancy Violation Theory framework, this study investigated differences in students ‘perceptions of teachers’ nonverbal immediacy by comparing American and international students studying in the U.S. The findings confirmed that (1) teachers' nonverbal immediacy is perceived as more appropriate by American students than by international students, (2) there are differences in evaluations of specific nonverbal immediacy behaviors by American students and international students, and (3) perceptions depended on student gender for some behaviors, but not teacher's gender. Learning was more positively related to perceived immediacy behaviors for international students than their American counterparts. 相似文献

Student plagiarism continues to threaten academic integrity. This investigation assessed whether an inoculation message strategy could combat university plagiarism by protecting student attitudes against pro-plagiarism justification arguments. Additionally, we sought theoretical confirmation of previous findings on involvement and accessibility in inoculation, examined the effects on vested interest, and evaluated matching and mismatching strategies in terms of affect- and rationality-based inoculation treatment messages and subsequent attack messages. A total of 225 students participated in three sessions spanning six weeks. Results indicated that none of the inoculation treatments conferred resistance as measured in attitude toward plagiarism, but all treatments enhanced involvement and attitude accessibility, and the fear- and rationality-based treatments enhanced vested interest. Additionally, fear-based treatments derogated the source of the message. Results also suggest that a matching strategy is superior with both affect- and rationality-based attack messages, such that inoculation treatments are most effective when using the same argument bases (e.g., affective or rational) as the attack message. These results offer guidance for crafting communication campaign strategies to reduce the occurrence of student plagiarism offenses. 相似文献

ABSTRACTTarget audience ratings of the likely impact of persuasive messages, known as perceived message effectiveness (PME), are commonly used during message development and selection. PME is also used to examine receptivity of messages after they are fully developed or deployed. Despite this, we know little about the conceptual and methodological characteristics of extant PME measures used in the literature. We conducted a systematic review of tobacco education video, print, and audio campaign studies to examine conceptual and methodological characteristics of PME measures. One hundred twenty-six PME measures from 75 studies conducted in 21 countries with more than 61,000 participants were reviewed. Results indicated considerable variability in measures’ focus on general perceptions of a message (i.e., message perceptions) vs. perceptions of expected message effects (i.e., effects perceptions). Considerable variability was also found on underlying persuasive constructs, use of referents, and referencing of behavior in PME items and measures. We conclude with several recommendations for future research on PME measurement and validation. 相似文献
