"Cumulative Trauma, Personal and Social Resources, and Post-traumatic Stress Symptoms Among Income-assisted Single Mothers"
(Springer Verlag, 2010) Wilk, Piotr; Avison, William R.; Ray, Susan; Samuels-Dennis, Joan; Ford-Gilboe, Marilyn
Data from 247 single mothers were used to partially validate a theoretical model that highlights the process through which post-traumatic stress disorder (PTSD) develops among women. Structural equation modeling was used to assess the direct and indirect relationship between cumulative trauma (CT) and mothers' PTSD symptom severity. Additionally, we examined the meditational role played by mothers' strains and resources and the moderating role played by mothers' residence in an intersectionally advantaged versus disadvantaged neighborhood. A good fit was found between the hypothesized model and data. Mothers' strains and personal resources played a significant mediating role in the relationship between CT and PTSD symptom severity. Neighborhood of residence did not moderate the CT-PTSD process. Implication for practice and treatment are discussed.
