A meta-analysis of media literacy interventions for deviant behaviors.

The present meta-analysis tested the effects of media literacy interventions on deviant behaviors, such as alcohol, smoking, body dissatisfaction, and eating disorders. A thorough literature search yielded a sample of 23 studies with 71 effect sizes. Results indicated that media literacy interventions showed a moderate effect size on reducing deviant behaviors. At posttest, Cohen's d = −0.32, 95% CI = [-0.43, −0.21]; at follow-up test, d = −0.23, 95% CI = [-0.31, −0.16]. There was no difference between the posttest and follow-up test. The present meta-analysis illustrates that media literacy interventions decrease deviant behaviors, and media literacy education is necessary for the positive development of children and adolescents. • Media literacy interventions reduces adolescent deviant behavior. • The effect sizes of media literacy interventions are moderate. • Media literacy intervention effects could maintain for a long time.
