Nursing students are at risk for developing secondary traumatic stress (STS) while completing their clinical training. Kristen Oakley synthesized the research on the prevalence, severity, and experience of STS and its associated factors in prelicensure nursing students. Findings from their review of 25 studies revealed a range of STS symptom severity levels and associated factors; however, measurement is hampered by researchers' use of other concepts, like compassion fatigue.
