Social Media as Information Source: Recency of Updates and Credibility of Information
Summary (3 min read)
The MAIN Model and Recency of Updates
- The MAIN model (Sundar, 2008) describes technological affordances that allow people to heuristically process cues when making judgments about the credibility of an online source.
- Agency cues capitalize on heuristics that emphasize credibility cues that, for example, are computer- (rather than user-) generated.
- This leads to the first hypothesis of the current study: H1: Recency of updating on a social media site will be positively associated with source credibility of the site’s source.
- A central tenet of involvement is the sense 174 Journal of Computer-Mediated Communication 19 (2014) 171–183 © 2013 International Communication Association that the individual partakes in an active psychological processing of that content.
- Based on this possibility, the following hypothesis is posited: H3: There will be a positive association between recency and cognitive elaboration.
Overview
- In order to test the hypotheses offered in the current study, a 3 condition experiment was designed.
- A mock Twitter page for the American Heart Association was created to represent a page devoted to the dissemination of information regarding heart disease.
- Participants viewed the Twitter page, and then responded to measures of cognitive elaboration (Perse, 1990) and source credibility (McCroskey & Teven, 1999).
Materials
- Participants were asked to view one of three mock Twitter pages .
- The pages were designed to appear as if the user was attempting to disseminate information and recent updates about heart disease.
- The page was made to appear as one from the American Heart Association for two reasons: Second, the assumption was made that an ‘‘official’’ page associated with the topic 176 Journal of Computer-Mediated Communication 19 (2014) 171–183 © 2013 International Communication Association would be more realistic in terms of fast updates.
- The three pages represented three different levels of update recency: fast (most recent post approximately 1 minute ago, n = 63), medium (most recent post approximately 1 hour ago, n = 56), and slow (most recent post approximately 1 day ago, n = 62).
Instrumentation
- After viewing the mock Twitter page, participants were asked to respond to two measures: one for cognitive elaboration (Perse, 1990) and one for source credibility (McCroskey & Teven, 1999).
- Cognitive elaboration was measured using a version of Perse’s (1990) five-item measure, modified to reflect the previously viewed Twitter page.
- Using a five-point response scale (5 = strongly agree, 1 = strongly disagree), people reported their level of agreement with each item (i.e., When I looked at this page, I thought about it over and over again).
- All five items formed a unidimensional solution with acceptable reliability (α = .68), so all five items were averaged to create an elaboration index.
- McCroskey and Teven’s (1999) source credibility measure contains three separate constructs: competence, goodwill, and trustworthiness.
Procedure
- Participants were informed about the research opportunity in class.
- Participants went to the website, and read the informed consent.
- After clicking on a button called ‘‘Begin Study,’’ they were directed to a program that randomly assigned participants to view one of the three mock Twitter pages.
- After each participant had viewed the page, they were instructed to click on another link that sent them to the questionnaire.
- This ensured participant’s names were kept separate from their responses.
Results
- Hypothesis 1 predicted that recency of updating on a social media page would be positively associated with source credibility for the page’s owner.
- The results of the planned contrast analysis for competence suggested that the linear pattern predicted between recency and competence was not evident in the data, t (171) = 0.188, p = .426 (one-tailed).
- To test this hypothesis, the bivariate correlations between cognitive elaboration and each of the three credibility measures were analyzed.
- Thus the data were consistent with hypothesis 2.
- Hypothesis 3 predicted that a positive relationship would exist between recency of updates and cognitive elaboration.
Post hoc analyses
- The results of the hypothesis tests suggested that a possible mediation effect between recency of updates and credibility measures was present in the data.
- The data seemed, at a descriptive level, to suggest that recency of updates indirectly affected credibility judgments through cognitive elaboration.
- A path analysis evaluated the possibility that the effect of recency of updates on credibility was mediated by the amount of cognitive elaboration in which a participant was engaged.
Discussion
- The current study was designed to examine the impact that the recency/speed of updates on a social media page had on judgments of source credibility and the amount of cognitive elaboration a viewer 178 Journal of Computer-Mediated Communication 19 (2014) 171–183 © 2013 International Communication Association had after exposure to the page.
- Specifically, participants looked at a Twitter page about heart disease in one of three recency conditions, and then responded to measures of cognitive elaboration (Perse, 1990) and source credibility (McCrosky & Tevern, 1999).
- Data are consistent with the notion that recency of updates impacted cognitive elaboration, which in turn impacted source credibility.
Study Findings
- The current study predicted that recency of updating would have a positive linear effect on perceived source credibility such that faster updates would lead to increased source credibility.
- The data were consistent with this post hoc model.
- The findings suggest that recency of updates might not have a direct impact on source credibility, but instead, that cognitive elaboration is a mediator in the relationship between recency of updates and credibility.
- It also suggests that Sundar’s (2008) notion of the machine heuristic may operate in part because system-generated cues can create a situation that consumers of information need to think more about, and this thinking leads to higher judgments of credibility.
- The immediacy of updating that is a hallmark of Twitter (Levinson, 2009) is likely a major reason this channel is growing in use for informational purposes, including under situations of risk and crisis.
Limitations and Future Directions
- Perhaps the biggest limitation is the small effect size of the linear relationship between recency of updates and cognitive elaboration.
- College students were used for this research in part because they are heavy users of social media.
- One other potential limitation of the current study is the cognitive elaboration scale (Perse, 1990) utilized.
Conclusion
- The current study examined how recency of updates on a social media page impacted source credibility and cognitive elaboration after exposure to the page.
- As social media becomes a more heavily used information source, even for things as critical as risks and crises, the gatekeeping function of that information also falls more into the hands of the page users, rather than the page creators.
- As such, it is important to continue learning more about this process, and learning about how and why credibility judgments are made about social media information.

Q2. What future works have the authors mentioned in the paper "Social media as information source: recency of updates and credibility of information" ?
Future studies examining a topic that requires faster updates might see an increased effect size between recency and cognitive elaboration. Thus, future studies can include this recency of updating as an important concept to study, and can more completely examine issues of topic and relevance in these studies. It is possible that future research, using topics with more personal relevance, may result in different findings, especially in regard to the effects sizes found. It would be interesting for future research to examine what specific thoughts the recency of updating leads to, and what specific thoughts lead to credibility judgments.
