【Background:】 Individuals who treat trauma are at significant risk of vicarious traumatization and burnout. Somatic Experiencing® (SE®) is a resiliency-focused trauma treatment modality designed to address autonomic nervous system (ANS) dysregulation and its impacted physical health and mental health symptoms e.g., anxiety, depression, post-traumatic stress disorder, migraines, fibromyalgia, and chronic fatigue, etc. The SE® training supports the development of clinical skills to reduce physical health/mental health symptoms as well as increase clinician resilience. Individuals who display resilience often have increased experiences of well-being (quality of life) and decreased levels of self-reported psychological symptoms. Greater resilience could mitigate the risks to providers and the clients they treat. 【Materials and Methods:】 This within-groups, longitudinal study assessed students (N = 18) over the course of a 3-year SE® practitioner training. This training focuses on increased ANS, physical, and emotional regulation skills. The convenience of a web-based survey allowed for: measures of a general quality of life (WHOQOL-BREF), psychological symptoms, somatic, anxiety, and depressive symptoms (PHQ-SADS), as well as a measure of early life exposure to adversity (CDC/Kaiser Permanente ACE Score Calculator Questionnaire). The clinician survey was conducted yearly for 3 years. Future studies would do well to also include laboratory-based objective measures of ANS functioning. 【Results:】 ANOVA with repeated measures showed that there were significant reductions in anxiety symptoms (GAD7, p < 0.001) and somatization symptoms (PHQ15, p < 0.001). Health-related quality of life (a measure of physical well-being) and social quality of life (a measure of interpersonal well-being) both increased significantly (Health QoL p = 0.028; Social QoL p = 0.046). 【Conclusions:】 Results suggest that professionals attending the 3-year SE® training course experience a significant improvement in self-reported measures associated with resiliency including: quality of life (well-being) and psychological symptoms (anxiety and somatization). Our results support the importance of future research in a larger sample and support the exploration, cross-sectionally and prospectively, of the relationship of clinician resiliency and changes in clinician resiliency with SE® training and clinical outcomes. These data have implications for other professions at risk of exposure to vicarious trauma (VT) including nurses, medical providers, and paramedics.
