The construct of news credibility has been of interest to communication scholars for decades, yet researchers have struggled to develop a measure of news credibility that demonstrates a reliable factor structure and construct validity. This study uses confirmatory factor analysis (CFA) and discriminant analysis to evaluate Abdulla and colleagues’ (2004) measure of news credibility. Results indicate that although the factor structure of the measure is replicable, the measure exhibits significant concerns related to discriminant validity. A revised measurement model employing a second-order factor for the news credibility scale that eliminates the discriminant validity concerns is proposed, and the implications of second-order factors in measurement models are discussed. 相似文献

Confirmatory factor analysis (CFA) is an under-used and often misunderstood statistical tool. CFA provides useful information about scale dimensionality and validity. This paper offers a brief and accessible introduction to the role of CFA in communication research. Some common issues with CFA including dimensionality and model fit are addressed. More frequent and informed use of CFA would likely improve the quality of measurement in quantitative communication research. 相似文献

The main aim of this paper is to evaluate the validity of a translated version the Information Literacy Self-Efficacy (ILSE) scale in a different socio-cultural context in Bangladesh. The 28-items of the ILSE scale was translated into Bangla to collect data from students of a public university in Bangladesh. To determine the underlying factor structures of the 28-items scale and its short version of 17-items, exploratory factor analyses (EFAs) were conducted with a sample of 394 students. Confirmatory factor analyses (CFAs) were performed with a group of undergraduate students (n = 267) to examine the validity of the scale. The 28-items and 17-items versions of the scale extracted four factors and three factors, respectively. In the CFA analyses, 23 out of the 28-items were found reliable although discriminant validity was not achieved between two constructs. While analyzing the 17-items subscale, 13-items were found to be reliable. Overall, the CFA model fit statistics for both the 23-items and 13-items support the use of the translated version of the ILSE scale for assessing self-efficacy for information literacy among Bangla-speaking population. 相似文献

This paper advances an argument in favor of conducting and reporting confirmatory factor analyses (CFA) on existing and previously validated scales and reporting the findings of those analyses in published research. Previous evidence of scale validity does not necessarily ensure validity in subsequent uses. Instead, scale invariance is best viewed as an empirical question. The case is made that CFA facilitates rather than hinders cross-studies comparisons, and that replication is good scientific practice. Reporting the outcomes of CFA on existing scales provides useful information that facilities knowledge generation and can minimize costly scientific dead-ends. 相似文献

Both classical and contemporary interpersonal theories have identified the social networks surrounding a couple as integral players in relational development and maintenance. The current project extends this line of research by designing (Study 1) and implementing (Study 2) a measurement of social network interdependence. Scales of network interference and facilitation are developed and probed using exploratory and confirmatory factor analysis. Results support distinct measures of network interference and facilitation. Invariance between differencing samples is tested for using multi-factor CFA. Results showed that measures of network interference and facilitation significantly vary between married and dating couples. Finally, convergent, divergent, and concurrent validity is tested for subscales using variables in relational turbulence theory. Results demonstrate that network interference and facilitation uniquely impact outcome variables above and beyond experiences of partner interference and facilitation. Results are discussed in terms of theory development. 相似文献

The development of the teacher clarity short inventory (TCSI) to measure clear teaching in the classroom 总被引：1，自引：0，他引：1
This study presents the Teacher Clarity Short Inventory (TCSI) as an alternative to existing measures of teacher clarity. Though existing scales measure both the clarity of content and classroom processes, they are disproportionate in length when compared to common instructional measures, such as measures of immediacy, student state motivation, and student affect. Analyses revealed a 10 item scale with an acceptable factor structure, acceptable reliability and validity. Furthermore, the instrument measures both the clarity of instructional content and instructional processes. 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

The relationship of the h-index with other bibliometric indicators at the micro level is analysed for Spanish CSIC scientists in Natural Resources, using publications downloaded from the Web of Science (1994–2004). Different activity and impact indicators were obtained to describe the research performance of scientists in different dimensions, being the h-index located through factor analysis in a quantitative dimension highly correlated with the absolute number of publications and citations. The need to include the remaining dimensions in the analysis of research performance of scientists and the risks of relying only on the h-index are stressed. The hypothesis that the achievement of some highly visible but intermediate-productive authors might be underestimated when compared with other scientists by means of the h-index is tested. 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

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

Validity of the verbal immediacy scale 总被引：1，自引：0，他引：1
The development and use of the verbal immediacy scale (Gorham, 1988) are outlined and discussed. Data are presented which bring into question the validity of the measure. It is concluded that the scale may not be a valid operationalization of the immediacy construct as outlined by Mehrabian (1971) and, even if it is, it generates a response set such that the meaning of the responses obtained is unknown. The scale is not recommended for continued use in communication research prior to its reformulation and additional testing for validity. 相似文献

The purpose of this study was to further validate the newly developed Grandchildren's Received Affection Scale (GRAS). To that end, young adult grandchildren (N = 317) completed the GRAS, along with two previously established measures of affectionate communication and a social desirability scale. The results of a series of Pearson correlational analyses and an exploratory factor analysis provide support for the concurrent, construct, and divergent validity of the GRAS. Thus, the GRAS is an appropriate instrument to assess grandchildren's received affectionate communication from their grandparents. 相似文献
