Abstract
Trauma-informed communities establish cross-sector coalitions that advocate for the use of trauma-informed practices. Whether and how communication occurs within newly established trauma-informed communities is unclear. We collected qualitative data and social network data from six trauma-informed community partnerships that received funding to build community capacity to address trauma across a range of special populations in Los Angeles county. We identified three communication network sub-types and highlight contributions of network leadership in setting the tone for cross-partnership communication. While partnership leaders shared the goal of strengthening cross-organizational communication, social network results illustrated a need to develop strategies that target these goals.
