Study Of Yoga Intervention To Reduce Secondary Traumatic Stress Among Public School Educators, Leslie Marie Hillen

Dissertations

A problem in education was the great amount of stress teachers were under. Secondary Traumatic Stress “is the emotional duress that results when an individual hears about the first-hand trauma experiences of another” (The National Child Traumatic Stress Network, n.d.). When teachers feel they cannot work or are overwhelmed with the demands of education, this can be attributed to Secondary Traumatic Stress (STS) (Caringi et al., 2015). Many teachers felt there was not enough support from the administration, as they not only deliver curriculum, but they also worried about the students’ mental health, home lives, hunger, and how to support …
