A Meta-Analysis of the Impact of Natural Disasters on Internalizing and Externalizing Problems in Youth.

ABSTRACT: Although exposure to natural disasters can lead to diverse mental health (MH) outcomes in youth, most child disaster MH research has focused on posttraumatic stress symptoms (PTSS). To highlight the likelihood of other MH outcomes, we meta-analyzed studies that have examined other (non-PTSS) internalizing and externalizing behavior problems in youth exposed to natural disasters. We used PRISMA guidelines to systematically gather studies that have examined the association between natural disaster exposure and non-PTSS internalizing and/or externalizing problems in samples of children and adolescents. Analyses of random effects models of 62 studies examining non-PTSS internalizing problems and 26 studies examining externalizing problems showed exposure to natural disasters was significantly associated with non-PTSS internalizing, r_mean = .18, k = 70, and externalizing problems, r_mean = .08; k = 31, in youth. Moderator analyses revealed a stronger association between disaster exposure and non-PTSS internalizing problems in countries with a "medium" Human Development Index (HDI) ranking, r = .56, than in countries with "high," r = .15, and "very high," r = .16, HDI rankings. We also found a stronger association between disaster exposure and externalizing problems in countries with a medium HDI ranking, r = .54, versus high, r = .05, and very high, r = .04, HDI rankings, and based on parent, r = .16, compared to child, r = -.01, report. Results support the need for assessment of multiple postdisaster MH outcomes to inform comprehensive interventions. We also include a discussion of the state of the disaster MH research.
