Posttraumatic stress moderates return intentions: a factorial survey experiment with internally displaced persons in Nigeria.

Background: Persons displaced by conflict often consider returning to their area of origin. Lack of reliable information about conditions in the area of origin makes this decision more difficult. Displaced persons address this by seeking information from other sources, but must then assess the credibility of these sources. Objective: This study examines the role of symptoms of posttraumatic stress as a moderator of how information from a trustworthy source influences return intentions among displaced persons. Method : We test our hypotheses with a factorial survey experiment, drawing participants ( N  = 822) from residents of internally displaced person (IDP) camps in northeastern Nigeria. Results: Information from a more trustworthy source led to increased return intentions. However, the more participants reported symptoms of posttraumatic stress, the smaller the effect source trustworthiness had on their return intentions. Conclusions: Findings highlight how traumatic experiences during wartime can undermine the effectiveness of the provision of information from a trustworthy source about good conditions in displaced persons' areas of origin, and suggest that interventions addressing posttraumatic stress could have downstream effects on safe, durable, and dignified return.
