Knowledge gap effects in a health information campaign
Public Opinion Quarterly
|December 7, 1983
Summary
A cardiovascular health campaign changed knowledge predictors. Initially, education mattered most, but later, motivation factors like age and perceived heart attack threat became significant, suggesting media can alter knowledge gaps.
Area of Science:
- Public Health
- Health Communication
- Social Science
Background:
- Cardiovascular health knowledge is crucial for prevention.
- Mass media campaigns aim to disseminate health information.
- Understanding how campaigns affect knowledge gaps is important.
Purpose of the Study:
- To evaluate a campaign designed to increase cardiovascular health knowledge.
- To examine how predictors of knowledge change over time following a media campaign.
Main Methods:
- The study evaluated a campaign targeting cardiovascular health knowledge.
- Statistical analysis was used to identify significant predictors of knowledge before and after the campaign.
Main Results:
- Education was a significant predictor of knowledge pre-campaign but not post-campaign.
- Age and perceived threat of heart attack became significant predictors of knowledge post-campaign.
- The campaign influenced the factors determining cardiovascular health knowledge.
Conclusions:
- Mass media campaigns can alter knowledge gaps, potentially closing them.
- Motivation to acquire health information is a key factor influencing knowledge gap effects.
- Campaigns can shift the influence of demographic and psychological factors on health knowledge.
