RESUMEN
Externalizing disorders emerge most readily during adolescence, especially in traumatized population. In this context, it is necessary to determine the factors influencing these disorders. The aim of this study was to evaluate the role of polyvictimization in developing externalizing symptoms while considering the possible effects of active coping related to the search for social support. The participants were 78 adolescents ( M = 14.18, SD = 1.63) cared for in child and adolescent protection public services in Chile. The results of multiple regression analysis indicated that polyvictimization was a good predictor of externalizing symptoms, but searching for social support acted as a moderator in that relationship. The results show that searching for social support acts as a protective factor and decreases the adverse influence of polyvictimization over externalizing symptoms. Prevention and intervention programs should consider improvements in the coping strategies of poly-victims with externalizing problems.
