There is a substantial gap between those people in the United States who identify as being favorable toward organ donation (~90%) and those registered as donors (~30%). A growing body of evidence suggests Department of Motor Vehicles (DMV) offices are effective sites for facilitating higher organ donor registration rates on a national scale. The goal of the current study was to determine the utility and sustainability of a message immediacy approach, which draws from theoretical concepts such as priming and cues to action. Message immediacy requires individuals be: (a) exposed to a message that prompts an action, (b) in an environment where a prescribed action or behavior can be enacted, and (c) favorable toward the promoted behavior or action. Thirty-four Michigan counties, divided into three implementation groups, received campaigns in October (Group 1), November (Group 2), and December (Group 3) of 2009. Registration rates for three to six months after campaign implementation indicate that the on-site message prompts almost doubled registration rates in DMV offices. Additionally, preliminary cost-effectiveness evidence suggests message immediacy offers a relatively inexpensive campaign strategy. 相似文献

Fast-paced and arousing anti-drug ads, considered to have high perceived message sensation value (PMSV), enhance message processing and reduce drug use among young adults. Studies have yet to explore the relationship between specific, PMSV-enhancing message features and outcomes related to persuasion. Messaris’ (1997) concept of syntactic indeterminacy provides one plausible explanation for why message features contained in high PMSV ads might enhance message processing and subsequent changes in attitudes and behavior. The study explored this explanation by coding specific anti-tobacco ads for PMSV-enhancing features, merging these codes to a telephone survey among teens, and testing the relationship between message features and processing. The number of unrelated cuts and the use of suspenseful features (intense imagery and a second-half punch) increased message processing among older teens. An additive index comprised of these features was associated with message processing among both younger and older teens. Theoretical and practical implications are discussed. 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

In its original presentation, scores on two of the three subscales of the Classroom Citizenship Behavior scale were highly reliable. Scores on the subscale measuring the third dimension of classroom citizenship behavior, Courtesy, had poor reliability. We inductively derived additional items for the Courtesy subscale and tested structure and reliability of the revised scale. Exploratory factor analysis indicated that the scale readily divided into three factors of six items each, consistent with the proposed model. Furthermore, the subscale scores associated with these factors demonstrated high reliability. Next, two additional communication classes completed the revised scale and confirmatory factor analyses were run on the new version of the three-factor scale. Fit indices were good. The revised Classroom Citizenship Behaviors scale provides a stronger tool for investigating student behaviors that contribute to the effective functioning of the classroom environment. 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

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 study employed factor‐analytic techniques in two separate experiments to determine the dimensions of message interpretation when different opinions on black‐white relationships were expressed. People in five cities responded to messages varying in perceived racial militancy. The results yielded a factor structure with three strong and pure dimensions accounting for 68 percent of the variance. Suggestions for the use of these scales in a variety of situations were offered. 相似文献

In this article, we investigated (a) whether the commonly reported 3 dimensions of source credibility (expertise, trustworthiness, and attractiveness) are applicable to both Americans and Koreans, and (b) which of those 3 dimensions exerted more influence on the dependent variables in each country. Findings suggest that the dimensionality of source credibility was remarkably similar between the 2 samples. The influence of 3 source credibility dimensions varied by the dependent variables. Attractiveness, expertise, and trustworthiness were equally important to purchase intentions. All 3 dimensions affected involvement with the advertisement message equally. Only trustworthiness had a significant impact on attitude toward brand and brand beliefs. In terms of attitude toward the advertisement, perceived attractiveness of the endorser was more important than expertise and trustworthiness. 相似文献

This experiment investigates the effects of an advertorial message on 4 dimensions of reader involvement. The use of the advertorial format was found to have increased participants' perceived message relevance, attention to written message, message elaboration, and message recall over the use of a standard advertisement format. Responses to labeled and unlabeled versions of the same advertorial did not vary significantly. Although participants perceived both labeled and unlabeled advertorials to be advertisements, rather than editorial material, more than two thirds of the participants who were exposed to a labeled advertorial failed to recall the presence of the label. Our findings indicate that the advertorial format fools readers into greater involvement with the advertising message and that the presence of advertorial labels may not be particularly effective in alerting consumers to the true nature of the message. 相似文献

This study investigated the influence that speaker characteristics other than dimensions of source credibility may have in the formation of listeners’ impressions of speaker credibility. It was found that the responses followed a simple information averaging model in about 80% of all cases. For the remaining 20% of the listeners, however, there was a significant interaction between traits. This mixed effect suggests caution in the interpretation of results of credibility studies. It was found further that all positive and negative source credibility dimensions can be treated safely as equal in weight, except for the negative pole of the Trustworthiness dimension; an untrustworthy speaker, regardless of his other qualities, was viewed as a questionable message source. 相似文献

This report is on the development and testing of a message elaboration measure. The reliability of the message elaboration scale is high μ = .86 to .94 over several studies. Confirmatory factor analytic procedures support the structure of the scale. Patterns of correlations with existing measures of cognitive processes also support the validity of the message elaboration measure. 相似文献

ABSTRACTResearch on self-affirmation has potential to inform the field’s understanding of health message resistance and acceptance. However, widely used self-affirmation instruments have several disadvantages that can lead to inconsistent success in generating self-affirmation and thus may explain inconsistent self-affirmation effects, or at the very least make their use cumbersome. In a series of three sequential studies, we introduced and tested a brief attribute scale format self-affirmation induction (brief scale affirmation task, or B-SAT) that was based on the 32-item attribute scale self-affirmation induction developed by Napper, Harris, and Epton. Using different behavioral contexts, we compared the performance of the B-SAT with that of two widely used self-affirmation inductions, i.e., the value essay task and the 32-item attribute scale. From a convergent validity perspective, the B-SAT performed as effectively as the two existing inductions in making people aware of their cherished and desirable values. From a predictive validity perspective, the B-SAT reduced defensive responses to a self-relevant health message and improved instrumental attitude toward the recommended behavior. 相似文献

Due to the massive uptake of online communication, people receive countless notifications on a given day. Governments also send more and more information via computer mediated communication instead of writing a paper letter to citizens. As a consequence, governments are increasingly exposed to the risk that citizens do not notice or act upon notifications that refer to governmental (sometimes legally binding) messages. This in turn may result in non-compliant behavior. Through a vignette study in three large scale surveys held in the Netherlands in 2015 and 2016, we have investigated how the channel (paper letter channel vs. e-mail channel that notifies that there is a digital letter available at a web portal) influences the speed with which people intend to read the actual content of a message while taking digital skills and expectations of the contents of a message into account. Results show that the channel has a significant and strong impact on the speed with which citizens read the contents of the message. This means that there is a risk that the efficiency gains that are won by communicating electronically are lost in effectiveness due to increased non-compliance because people do not actually see the government information that is sent to them. Therefore, it is important to think of new ways to effectively notifying people of new information in an online environment. 相似文献

This study measured the effects of message threat level, message quality, and initial receiver attitude on attitude change and evaluations of source credibility. Significant positive attitude change occurred as the main effect of message quality, with no main or interaction effects for threat or receiver attitude. Significant source derogation on the dimensions of trustworthiness, objectivity, and expertness occurred as primary effects of message threat level and initial receiver attitude, with the greatest derogation occurring among disagreeing receivers exposed to high threat messages. The implications of these results for the theory of psychological reactance is discussed. 相似文献

Dyadic and normative accessibility are hypothesized to correlate positively with three task dimensions: variety, autonomy and identity. The presumed independence of the dyadic and normative accessibility scales is also investigated. Data were collected from 40 middle level managers in a variety of organizations. Results show significant relationships between dyadic accessibility and the characteristics of variety and autonomy. Tasks with high identity plausibly do not require much supervision. Follert's scale for normative accessibility seems to have some serious validity problems, and probably ought to be replaced or newly validated. 相似文献
