A longitudinal analysis of social integration, perceived emotional support, and posttraumatic stress in a community sample of sexual assault survivors.

Social support has long been recognized as an individual and community resource that can reduce stress and promote well-being, both in everyday life and after traumatic events. This study sought to explore the impact of two types of social support-social integration and perceived emotional support-on sexual assault survivors' longitudinal experiences of posttraumatic stress. We built on a previously conducted latent transition analysis to identify whether social integration and perceived emotional support predicted membership in each latent class, in addition to whether varied levels of support predicted transitions between latent classes over 1 year. Based on responses from a community sample of sexual assault survivors in an urban area of the midwestern United States, we found that while both types of social support predicted latent class membership, the impact of each type of support varied between latent classes, such that social integration and perceived emotional support were differently impactful depending on one's experience of posttraumatic stress. Findings contribute to the ongoing discussion of social support as a vital community resource and suggest circumstances in which social integration and perceived emotional support may each be especially useful in reducing distress and promoting health.
