AbstractWe examined the psychological functions of nostalgia (hanin in Arabic) among Syrian refugees residing in Saudi Arabia, who were forcibly displaced during the Syrian civil war. Forced displacement entails disruption, loss, and mourning, creating a salient contrast between one's past and present circumstances, which could attenuate the benefits of nostalgia. Studying this population thus affords a strong test of the boundaries of nostalgia's functionality. We experimentally induced nostalgia via vivid autobiographical recall and then assessed various psychological functions, as well as current affect. A supplemental objective was to examine the role of dispositional resilience. Most established benefits of nostalgia also accrued to Syrian refugees. However, contrary to previous findings, nostalgia decreased optimism, highlighting the limits of its palliative capacity among displaced individuals. As hypothesized, the impact of nostalgia was moderated by dispositional resilience, which acted as a catalyst of the emotion's benefits and as an inhibitor of its costs.
