Abstract

OBJECTIVE: A quantitative meta-analysis set out to consolidate the effect of experimental studies of media exposure to disasters and large-scale violence on negative psychological outcomes.

METHOD: The meta-analysis included 18 experimental studies with an overall sample size of 1,634 to obtain an overall effect size and information regarding moderators of the effect size.

RESULTS: An overall significant and large effect size of Hedges' g of 1.61 showed that, across studies, media exposure to disasters and large-scale violence was followed by negative psychological outcomes. Outcome type was a significant moderator, with anxiety reactions showing an especially strong effect. Community sensitization was a significant moderator, with studies conducted in a region that had recently been exposed to the type of disaster or violence portrayed in the media showing especially large effect sizes.

CONCLUSION: The results indicate that media exposure to disasters and large-scale violence can cause negative psychological outcomes, at least transiently. Limitations included a lack of statistical power in some moderator analyses and the inability to draw inferences about the duration of effects. There is a need for further research aimed at identifying the possible cumulative effects of media exposure and identification of groups at greatest risk for harmful outcomes.
