Abstract
Purpose
To investigate how media literacy and varied media consumption influenced substance use behavior.
Design
A cross-sectional survey was conducted.
Setting
Online survey was conducted June 22-July 18, 2020, with quality checks.
Subjects
The study recruited U.S. residents aged 18 and older who were proficient in English (N = 1264). Panel sampling using quotas reflecting U.S. census was employed as an alternative to random digit dialing sampling.
Measures
Substance use behavior, media literacy for news, liberal media use, conservative media use, social media use, and demographics were assessed.
Results
Hierarchical multiple regression analysis was conducted. Media literacy for news was negatively associated with substance use (β = −.15, SE = .08, P < 0.01, [95% CI: −.36, .06]) and interaction effect between social media use and media literacy for news on substance use behavior was significant (β = .47, SE = .05, P = 0.02, [95% CI: .02, .20]) in the final model (F(12, 1207) = 33.21, R2 = 25%).
Conclusions
Media literacy for news has a negative association with substance use behavior. Social media use, specifically, diminishes the effect of media literacy skills on substance use behavior. The prediction is based on correlational data. Further investigations are required to examine how individuals’ specific patterns of media use impact substance use behavior as part of media literacy intervention efforts.
