The use of coping strategies can protect against the detrimental effects of many work-related stressors. Given the stressful nature of casework with traumatized children and families, there is a need to better understand how to prevent the experience of secondary trauma. The goal of this study is to examine child welfare caseworkers’ experience of secondary traumatic stress and the extent to which coping strategies act as a buffer. Participants in this study were recruited as part of a larger workforce study and invited to complete an online survey. Results showed relatively high levels of secondary trauma, with 26% scoring in the “severe” range. Those who utilized coping strategies such as a clear self-care plan, participation in activities or hobbies, or a work-to-home transition plan had fewer symptoms of secondary traumatic stress both concurrently and three years later.
