While much research documents the influence of self-efficacy on enactment of health behaviors, relatively less attention has been given to the factors that influence self-efficacy. To enhance our understanding of the various sources of self-efficacy, this study integrated social identity theory into this context and proposed and tested a model, which describes a process through which social identity can influence self-efficacy of engaging in health-related behaviors. Consistent with the proposed meditational model, the findings showed that individuals who had stronger social identity with a given social group perceived greater social support from the group, which in turn predicted higher self-efficacy of engaging in a health-related behavior advocated by the group, and ultimately predicted greater behavioral intention. Theoretical and practical implications are discussed. 相似文献

The cognitive-functional model of discrete negative emotions and attitude change (CFM; Nabi, 1999) attempts to bridge the theoretical gap between “emotional” and “rational” approaches to persuasion by focusing on how emotions motivate attention to and processing of persuasive messages. As a first test of the CFM, this study explored the effects of 2 emotions, anger and fear, and 2 levels of expectation of message reassurance, certainty and uncertainty, on attitudes toward domestic terrorism legislation. Results supported a main effect for emotion type, suggesting that anger promotes deeper information processing than fear, and a main effect for reassurance certainty level, with uncertainty promoting deeper information processing. The expected interaction between emotion type and reassurance expectation level was not found. Implications of these findings for the model and persuasion research generally are discussed. 相似文献

Mental health is a stigmatized issue in many parts of the world. We conducted a survey of Chinese adults (n?=?661) to examine predictors of intentions to seek information related to mental health. Attitudes and subjective norms positively influenced intentions to seek mental health information, with subjective norms being a stronger predictor. Cultural identity was negatively associated with intentions to seek mental health information, with participants who held a stronger cultural identity being less likely to seek information related to mental health. Media use was positively associated with intentions to seek information. This research highlights that cultural identity may influence mental health information seeking, and that health campaigns could focus more on influencing subjective norms, thereby changing the seeking intention of Chinese adults regarding mental health information. Additionally, practitioners may want to explore possible ways of providing health information to people with strong cultural identity, as they may be less likely to seek out information on their own. 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

Much research on risk perception and health behavior has examined cognitive dimensions of risk but not affective dimensions. To address this gap, this study examines both cognitive risk perception (perceived risk of susceptibility and severity) and affective risk perception (worry) in the context of food safety risks in East Asia. We investigate their roles in independently and jointly predicting intention to consume outbreak-associated food products, as well as mediating the influences of news exposure and attention on intention. Data from a nationwide survey in South Korea (N = 1500) lent overall support for our hypotheses in both cases of processed food from China and seafood from Japan. Our findings show: (1) both perceived risk and worry were negatively associated with food consumption intention, and the association between perceived risk and intention was stronger among those higher in worry; (2) news attention had stronger associations with perceived risk and worry than news exposure, and attention moderated the relationship between news exposure and perceived risk; and (3) perceived risk and worry mediated the associations between news use and food consumption intention. Implications and limitations of the findings are discussed. 相似文献

This study examines the influence of individual-level characteristics on the spiral of silence effect in two countries, Singapore and the United States, making it the first cross-cultural test of the theory and thereby addressing a gap in the literature highlighted by Schefule and Moy (International Journal of Public Opinion Research, 12, 2000, 3–28). In two identical, representative telephone polls of 668 adults conducted in Singapore and 412 adults in Washington, DC, respondents were asked to indicate how likely they would be to discuss publicly two controversial issues: interracial marriage and equal rights for homosexuals. The proposed model for predicting outspokenness adds a variety of new predictors, such as culturally influenced self-concepts, fear of isolation, and communication apprehension, along with other more traditional predictors of outspokenness, such as a person's perception of the opinion climate, media exposure, issue salience, and demographics. The findings provide partial support for the spiral of silence hypothesis in Singapore, but not in the United States. Respondents’ perception of the future opinion climate in Singapore interacted with issue salience to influence their level of outspokenness; American respondents did not exhibit such an interaction effect. In both countries, however, outspokenness was associated with respondents’ perceived importance of the issue and their communication apprehension. Media exposure was not associated with outspokenness in either country. 相似文献

Based on the information-as-coping perspective, we provided a theoretical framework to understand how the quality of government information and citizens' partisanship impact citizens' wellbeing in terms of satisfaction with life and anxiety during COVID-19. With survey data from 705 respondents in Indonesia, we found that government information quality is of vital importance in helping citizens get ready to fight the pandemic, as well as lowering their anxiety. Our results show that higher information quality leads to a higher ability to respond quickly to the crisis, as well as a reduced level of information overload. While partisanship is a significant predictor of information overload, it had no significant impact on perceived quick response ability. Quick response ability and information overload, in turn, predict anxiety and citizen's satisfaction with life. 相似文献

This conceptual analysis of how emotions and feelings are characterized as motivators for information seeking draws on the appraisal theories suggesting that emotions motivate individuals by triggering action readiness to approach or avoid sources of information. The findings indicate that emotions and feelings motivate in five major ways: they start, expand, limit, or terminate the information-seeking process, or they lead to information avoidance. Information scientists have mainly characterized the motivational aspects of negatively colored emotions such as anxiety and fear while the role of positive emotions such as joy has remained secondary. 相似文献

The communicative ecology model of successful aging (CEMSA), which theorizes how people’s communication can influence their experiences of successful aging, takes as axiomatic that aging involves uncertainty. In two studies, with data from the U.S. and the U.K., we compared the viability of two conceptualizations of uncertainty about aging in the CEMSA: the model’s original operationalization, uncertainty discrepancy, and an alternative, the perceived probability of negative experiences (PPNE) associated with aging. In both studies, uncertainty discrepancy and PPNE contributed independently to attitudes toward aging; PPNE emerged as a stronger predictor of people’s affective reactions to aging. These findings underscore the importance of multifaceted views of uncertainty for scholars of communication and aging. 相似文献

In some romantic relationships, one partner has more power over joint decisions than the other. This study examines relative commitment as a key predictor of which partner has more power and developed a model based on classic interdependence theory. A survey was conducted (N = 324) using new measures of the key variables to test the model. When desire for control was high, relative commitment predicted self-perceived power, which predicted major and minor decision making as well as dominant conflict strategies. These results are consistent with the proposed modification of interdependence theory concerning desire for control. 相似文献

Much research on public communication campaigns has shown that the negative appeals (e.g. fear, guilt appeals) commonly used may not be effective for encouraging prosocial behaviors, as they can facilitate defensive processing. Self-affirmation theory suggests that self-affirmation may be a useful strategy for mitigating defensive responses to potentially self-threatening messages. This cross-national study explored the effect of self-affirmation on the persuasiveness of a threat appeal message in the context of climate change. An experiment with a 3 (no affirmation versus message-integrated affirmation versus message-separate affirmation)?×?2 (high self-threatening versus low self-threatening message)?×?2 (U.S. versus Korea) factorial design (N?=?225, U.S.; N?=?255, Korea) was employed to test this postulation. The results suggested that self-affirmation has a positive effect on perceived risk, attitude toward message, and intention to engage in environmentally-friendly behaviors, although this effect is limited to high self-threat conditions. Additionally, a statistically significant interaction between self-affirmation and culture was found for the effect on behavioral intention. Finally, message-integrated affirmation manipulation was found to be as effective as message-separate affirmation manipulation. The implications of these findings for public communication campaigns in terms of promoting prosocial behaviors are discussed. 相似文献
