Media literacy interventions positively impact knowledge, attitudes, and behaviors. More frequent sessions enhance effectiveness, while numerous components may reduce it, according to this meta-analysis.
Area of Science:
- Media Studies
- Education
- Psychology
Background:
- Media literacy interventions are prevalent but lack comprehensive meta-analytic assessment.
- Understanding the effectiveness of these interventions is crucial for educational and public health initiatives.
Purpose of the Study:
- To conduct a meta-analytic assessment of media literacy interventions.
- To determine the average effect size and identify moderators influencing intervention outcomes.
Main Methods:
- A meta-analysis of 51 media literacy interventions.
- Analysis of effect sizes across various outcomes including knowledge, attitudes, and behaviors.
Main Results:
- Media literacy interventions demonstrated a positive average effect size (d=.37).
- Interventions with more sessions were more effective.
- Interventions with more components were less effective.
- Effectiveness did not vary by agent, age, setting, involvement, topic, country, or publication status.
Conclusions:
- Media literacy interventions are effective in improving a range of outcomes.
- Intervention design, specifically session frequency and component number, influences effectiveness.
- Future interventions should consider optimizing session frequency for greater impact.
