The field of child welfare continues to be plagued by high rates of worker turnover that further complicate the challenging work of protecting and enhancing child welfare in the United States. The child welfare workforce plays a crucial role in promoting child well-being and preventing abuse and neglect, but safety, permanence, and well-being outcomes of children are negatively impacted by high rates of workers leaving their jobs. Numerous organizational and individual factors have been studied in relation to worker turnover, and while there is a foundation of research related to direct and indirect trauma separately, different typologies of trauma have rarely been studied together. This study examined child welfare workers' exposure to work-related trauma from a stress-response framework. A statewide sample of child welfare workers (n = 657) responded to items relating to their experiences of client perpetrated violence, deaths or injuries on their caseloads, and secondary trauma. They completed scales measuring their current levels of depression, anxiety, posttraumatic stress disorder, and overall commitment to the field of child welfare. Three typologies of trauma emerged: primary trauma, caseload trauma, and secondary trauma. Structural equation modeling analysis indicated that primary trauma had a small, but positive relationship with commitment to the field (B = .17, p , .05). Caseload trauma predicted workers' levels of secondary trauma (B = .14, p , .05), and secondary trauma had a strong, predictive relationship with worker mental health (B = .77, p , .001). Creating typologies to distinguish different kinds of trauma allowed for a nuanced look at workers' experiences and how they influence outcomes related to the mental health of workers and commitment to the field.
