Complex Trauma and Ecological Vulnerability: Development of a Resources Perspective Framework to Inform Longitudinal Examination.

Translation and application of current complex trauma knowledge for high-risk groups such as the homeless is needed. Existing research in this area has been limited by lack of a cohesive theoretical framework that captures the dynamic and heterogeneous nature of complex trauma within the context of ecological vulnerability (e.g. homelessness). This paper aims to address these gaps by proposing an integrated resources perspective framework situating Layne and colleagues' (Layne et al. 2009, 2010) concept of 'risk factor caravans' as central focus. We demonstrate how the 'risk factor caravan' representation captures current theoretical and clinical insights into the pervasive and enduring consequences of complex trauma exposure. Personal resources are highlighted as key for understanding resource loss and gain in the current context. Longitudinal person-centered approaches as integral methodological considerations for future application of this proposed framework are examined. Implications for reducing barriers to access of available support services are discussed. © Springer Nature Switzerland AG 2019.
