Adolescents in New Orleans were displaced by hurricane Katrina and returned to find their city devastated by this natural disaster. Although many studies have found a relationship between hurricane exposure and development of psychopathology, the current study evaluated this relationship within the context of protective and risk factors. Specifically, the current study evaluated whether community violence, parent support, and peer support moderated the relationship between hurricane exposure and adolescent PTSD or depression. Results found no relationship between hurricane exposure and adolescent depression. Although there was a main effect for hurricane exposure and PTSD, the proposed variables did not moderate this relationship. Results are discussed in the context of previous studies detailing the relationship between hurricane exposure and psychopathology as well as the impact that social support and community violence has on an adolescentís psychological functioning.
