Background: Following disasters, children and adolescents can use coping strategies to feel better. A growing body of studies investigated the relation between them and maladjustment/adjustment, i.e., negative symptomatology/positive indicators of development. Yet, these constructs are studied separately. Objective: We conducted two meta-analyses to examine the mean correlation between disaster-related coping strategies and indicators of maladjustment/adjustment following natural disasters in children and adolescents, considering the role of some moderators. Methods: We used PsycINFO, PubMed, Eric, and Scopus databases to identify articles on natural disasters (filters: participants [less than or equal to] 18 years at the disaster, peer-review, English language). Inclusion required investigating the relation between at least one coping strategy and at least one indicator of maladjustment (e.g., post-traumatic stress disorder, depression) and/or adjustment (e.g., self-efficacy, emotion understanding), for a total of 26 studies (k = 64, n = 9692, for maladjustment; k = 37, n = 3504, for adjustment).There were global positive significant correlations between coping strategies and negative symptomatology (r[subscript pooled] = 0.23) for maladjustment, and positive indicators (r[subscript pooled] = 0.17) for adjustment. Negative symptomatology positively correlated with escape (r = 0.19), social isolation (r = 0.15), submission (r = 0.64), and opposition (r = 0.16); positive indicators positively correlated with problem solving (r = 0.31), social support (r = 0.22), and submission (r = 0.30). We found a moderating role of age, disaster type, and continent for maladjustment. Conclusions: The study presented an analysis of the coping strategies that can be effective for children and adolescents dealing with natural disasters.
