In many countries, studies show declining levels of trust in news media at large. However, there still is no valid and accepted measure of generalized trust in news media. To establish and test a suitable measure, we chose two elaborate scales of related concepts: the scale on trust in media coverage of a specific topic by Kohring and Matthes and a credibility scale by Yale, Jensen, Carcioppolo, Sun, and Liu. We adapted both to measure generalized trust in news media and conducted a survey in Germany to (a) evaluate the dimensional structures of both adapted scales and (b) analyze their predictive validity by testing their explanative power on alternative media use. Both adapted scales yield well-fitting models but should be carefully treated with respect to discriminant validity. The adapted Kohring and Matthes scale successfully predicts alternative media use and can therefore be recommended for further research on generalized trust in news media. 相似文献

In this study, we provide evidence of construct and discriminant validity for measures of self-efficacy in using television, newspaper, and interpersonal communication to monitor politics in everyday life. Data were drawn from a survey of undergraduates (N = 576) at a large public university. Self-efficacy is a key mediating variable in social learning theory, consisting of a combination of beliefs that one can perform tasks and that desired consequences follow from successful performance. Self-efficacy subscales were correlated with media uses, exposure, intellectual stimulation, credibility, political efficacy, and participation, which supported construct validity of measures. Subscale correlations supported the discriminant validity of media self-efficacy measures. 相似文献

This investigation assessed the factorial structure and validity of the Service Provider Sociality Scale (SPSS). The SPSS was administered to 455 customers, including 255 undergraduate students attending a small Midwestern college and 200 residents in communities surrounding the college. Confirmatory factor analysis results indicated that the service provider sociality measurement model had significant composite reliability and discriminant validity. Implications and recommendations for further research are provided. 相似文献

As a result of the controversy over the dimensionality of the ethos/source credibility construct and the associated plethora of empirical studies in the 1960s and 1970s, Aristotle's dimension of “goodwill” has been dismissed by many contemporary theorists and researchers. It is argued that this occurred as a result of errors made in the earlier empirical research and that “goodwill” can be measured, contrary to earlier claims, and should be restored to its former status in rhetorical communication theory. Empirical research is reported indicating the existence of the goodwill dimension as part of the structure of the ethos/source credibility construct and a measure of that dimension is provided with evidence for its reliability and validity. 相似文献

The ability to evaluate predictions and theories hinges on accurate, error-free measurement. As a result, communication scientists seek both highly valid and highly reliable measures. Regarding validity claims, specifically, a hypothesis of content validity is typically tested via factor analysis. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) assume a linear relationship between indicators and the underlying construct. Thus, EFA and CFA miss instances of nonlinear unidimensionality, such as those encountered when a scale forms a Guttman Simplex. Given that such a measurement model is not uncommon and is difficult to detect, this article presents a method for testing the hypothesis of content validity when this kind of nonlinear relationship exists between scale items and the construct. 相似文献

Family communication patterns theory (FCPT) explores how family members communicate to create a shared social reality via conversation and conformity orientations. Recently, scholars have noted that the current conceptualization and operationalization of conformity orientation is unnecessarily narrow in scope by representing conformity as controlling and repressive, rather than as cultivating homogenous attitudes, beliefs, and values among family members. To address these concerns, we tested the factor structure of the most common measure in FCPT research, the Revised Family Communication Patterns scale (Study One). Based on theoretical and methodological concerns that emerged from Study One, we then created and validated a new scale in Study Two – the Expanded Conformity Orientation Scale (ECOS). Findings from Study Two demonstrated concurrent and discriminant validity. Implications for the use of the ECOS in future studies are discussed. 相似文献

This article explores perceptions of news credibility for television, newspapers, and online news. A survey was administered to a randomly selected sample of residents in Austin, Texas, to assess people's attitudes toward these 3 media channels. Contingent factors that might influence news credibility perceptions, such as media use and interpersonal discussion of news, were incorporated into the analysis. Findings suggest that people are generally skeptical of news emanating from all 3 media channels but do rate newspapers with the highest credibility, followed by online news and television news, respectively. Furthermore, opinions about news credibility seem to be correlated across media outlets. The data also show a moderate negative linkage between interpersonal discussion of news and perceptions of media credibility for television news but not for newspapers. When controlling for basic demographics, a positive correlation was found between interpersonal communication and online news credibility. Finally, a marginal association was noted between media use and public perceptions of credibility across all 3 media channels. 相似文献

Listener groups employed the Speech Dialect Attitudinal Scale (SDAS) to rate speakers in a variety of situations. These involved: (A) foreign accent, (B) regional dialect, (C) speech pathology, (D) broadcast news reporting, and (E) use of obscene language. Reliability of ratings was consistently high, with a median of .98. Evidence of construct validity was provided by the factor structures of SDAS item scores. Except in the case of the speech pathology experiment, the factor analyses yielded a remarkably consistent three‐factor structure: Socio‐Intellectual Status, Aesthetic Quality, and Dynamism. In each case, analyses of variance and covariance of SDAS scores discriminated among speakers differentiated by linguistic variation, further supporting the validity of SDAS data. 相似文献

Modeling Web-based library service quality 总被引：1，自引：0，他引：1
Studies of e-service quality have consistently used adaptations of service-quality measurement tools that have been adopted and extended from traditional service-quality frameworks. However, a fresh insight into the investigation of key determinants of Web-based library service quality, with an emphasis on how library customers perceive service quality, has much to offer. Key determinants were identified, and contributed to the development and empirical testing of a proposed conceptual model of service quality that encompasses environment, delivery, and outcome quality. Unlike the disconfirmation approach, the performance-only measure was used. Participants included postgraduates and academic staff from four research intensive universities in Malaysia. Exploratory factor analysis and confirmatory factor analysis using structural equation modeling was carried out in order to develop and validate a measurement model for Web-based service quality, which included three second-order dimensions and eight first-order dimensions. Insights into the conceptualization of Web-based library-service quality as a multidimensional hierarchical construct are provided. The emergence of specific determinants specific to the Web services supports the notion that measurement of electronic-service quality is different from traditional services, though they may share some common factors. 相似文献

Although social exchange has been frequently referred to as a framework for exploring employee-organization relationships, the role of potentially important exchange related variables such as communication climate and change communication are less understood. The present research aimed to assess the measurement properties of an expanded set of social exchange constructs. The measurement properties of change communication, communication climate, perceived organizational support, procedural justice, affective commitment, and cynicism toward organizational change were tested using competing confirmatory factor analytic models. After appropriately defining items and refining individual scales, confirmatory factor analyses provided evidence in support of an expanded set of social exchange constructs. Despite high correlations between some of the variables, tests for discriminant validity established that respondents (N = 500) could reliably distinguish between the full set of constructs. Furthermore, Harman's One Factor Test for common method variance suggested that the variance in the data could not be explained by a single construct. Practical implications for the use of this set of social exchange constructs in organizational contexts are discussed. 相似文献

An increasing number of local news stations are producing and broadcasting their newscasts in high-definition television (HDTV), but to date there has not been an investigation of audience perceptions of news in high definition. This study presents the results from an experiment investigating the influence of television form (image quality and field of view) on presence and audiences' perceptions of source credibility for news anchors and local news. The results demonstrate that improved image quality (HDTV) has a positive influence on audience perceptions of source credibility and the overall credibility of newscasts. Implications are discussed. 相似文献

The television medium has occupied a dominant place in Bangladesh. With the unprecedented expansion of the television industry, questions are being raised about a palpable rise in market-oriented journalism (MOJ) in the country. This article examines the theoretical and empirical relationship between MOJ and credibility of TV news. Three surrogate factors of MOJ including independence, social role, and objectivity, along with TV news credibility are analyzed for insights. The findings suggest that there is a complex relationship between the two constructs. To improve the perception of credibility of TV news, our findings suggest an important role of public journalism as an alternative to MOJ. 相似文献

Nontraditional sources of news, such as talk radio and the Internet, complement and sometimes replace traditional mainstream news sources. Using discriminant function analysis, this study reveals the role of values in predicting listening to political talk and religious radio programs. A model using the construct of “value equivalence” explains value differences between user and media that may affect whether or not news from nontraditional sources will be sought and used. Research questions are answered using data from the 2004 Pew Research Center Biennial Consumption Survey. Using selected independent variables (including value-based variables) to predict listening to the Rush Limbaugh program, 59% of all cases in this study were correctly classified. Using the same set of value-based variables to predict listening to religious radio shows yielded nearly 74% correctly classified cases. 相似文献

Exemplification (the use of examples) in news stories is a common method of providing information about social phenomena to make stories more interesting to audience members. However, previous research has consistently linked exemplification to highly inaccurate perceptions about the prevalence or severity of a given phenomena. The current study further explored outcomes of exemplification by examining the extent to which the practice influenced perceptions of news credibility. Exemplification of public opinion via layperson quotes was found to differentially affect perceptions of news story credibility. Anecdotal exemplification, however, did not predict credibility ratings. Implications for journalism and democratic participation as well as partisans' preference for congenial coverage in news stories are discussed. 相似文献

In the new media environment, hard news stories are no longer found solely in the “A” section of the paper or on the front page of a news Web site. They are now distributed widely, appearing in contexts as disparate as a partisan blog or your own e-mail inbox, forwarded by a friend. In this study, we investigate how the credibility of a news story is affected by the context in which it appears. Results of an experiment show a news story embedded in an uncivil partisan blog post appears more credible in contrast. Specifically, a blogger's incivility highlights the relative credibility of the newspaper article. We also find that incivility and partisan disagreement in an adjacent blog post produce stronger correlations between ratings of news and blog credibility. These findings suggest that news story credibility is affected by context and that these context effects can have surprising benefits for news organizations. Findings are consistent with predictions of social judgment theory. 相似文献

This study investigated the factor structure of source credibility within the context of three situations in which communication typically occurs. The study tested the hypothesis that the situation in which the speaker communicates will influence the receiver's perception of the dimensions underlying the credibility of that speaker. The results indicated that the factor structure of source credibility across situations was variant. The scales used to measure the factors of trustworthiness and expertness may reflect more than one perceptual element for the receiver. The study indicated further that different types of communication in the same situation yield different source credibility factor structures. 相似文献

ABSTRACT By administering an online experiment, this study examined how source and journalistic domains affect the perceived objectivity, message credibility, medium credibility, bias, and overall journalistic quality of news stories among an adult sample (N?=?370) recruited using Amazon’s Mechanical Turk (MTurk) service. Within the framework of the cognitive authority theory, the study found auto-written news stories were rated as more objective, credible (both message and medium credibility), and less biased. However, significant difference was found between a combined assessment condition (news stories with source and author information) and a message only assessment condition (news stories without source and author information) in the ratings of objectivity and credibility, but not bias. Moreover, significant differences were found in the objectivity and credibility ratings of auto-written and human-written news stories in the journalistic domains of politics, finance and sports news stories. In auto-written news stories, sports news stories were rated more objective and credible, while financial news stories were rated as more biased. In human-written stories, financial news stories were rated as more objective and credible. However, political news stories were rated as more biased among human-written news stories, and in cases where auto-written and human-written stories were combined. 相似文献

Development of a digital library demands extensive financial, human, and technological investments. Appropriate models and measurement tools are required to achieve the goals of these libraries to assess them. This research was conducted with the aim of developing and validating a tool to measure the maturity of a digital library based on the “digital library maturity model” (DLMM). Two sources including literature and experts' opinion were used to determine the criteria for each code. Expert opinion and confirmatory factor analysis were used to confirm the content and construct validity of the developed tool, respectively. The reliability of the designed tool was examined by the Cronbach's alpha test. Finally, the designed tool validity and reliability were confirmed. Managers of digital libraries can use this tool to understand the maturity level of their digital libraries and plan to improve the library or to attain advanced levels of maturity. 相似文献
