This study examines the effects of social networks on the disclosure of stigmatizing and traumatic sexual assault experiences. We analyzed publicly archived oral histories of Korean “comfort women” from World War II, employing an innovative method combining word embedding analysis, word frequency comparison, and grounded theory. By extracting their significant social relationships from narrated survivor stories, we parsed two distinctive disclosure patterns according to timing of disclosure: early disclosers and late disclosers. The latter were more socially embedded than the former, indicating the constraining aspect of social networks, in which the size of social networks was positively associated with delayed disclosure. Qualitative findings further elaborated that social networks have double-edged effects. Survivors’ familial networks functioned as both social constraints and social support for public disclosure. Yet, the late disclosers tend to exploit it more as constraints for the fear of transgenerational transmission of social scorn and stigma. The findings contribute to enhancing a culturally relevant understanding of trauma and the repercussions of human trafficking.
