No results posted yet for this study

Summary

The study examines whether people primarily want to confirm their prior attitudes in health-related information search, in an online environment using social tags for navigation. Participants were looking for information on the treatment of depression with antidepressants and psychotherapy. They were randomly assigned to two groups with either high or low credibility of the community who provides social tags, and two groups where participants' confidence in prior attitudes was heightened or lowered, and to two groups where either antidepressant tags were more popular or psychotherapy was more popular. The investigators measured attitude change toward the treatments and also navigation behavior.

Conditions

Interventions

OTHER

Social Tag Popularity

The relative size of treatment tags in a tag cloud was either larger for antidepressant treatments or psychotherapy treatments.

OTHER

Confidence in Prior Attitudes

Participants thought back of situations in which they were either confident or doubtful about their own knowledge. This should elicit a mindset where participants are more or less confident about their own prior attitudes.

OTHER

Source Credibility

The source credibility of the community that allegedly collected and labelled the blog posts was either high or low in terms of expertise. Either experts (high credibility) or first semester students (low credibility) did allegedly collect blog posts. This was indicated by banners on top of the navigation platform in the internet browser.
