Background/Objectives. Medical and social care professionals (MSCPs) are disproportionately affected by chronic occupational stress, placing them at elevated risk for autonomic dysregulation, affective disorders, and burnout. Method. This preliminary study includes data obtained from two samples. The data protocols were approved by University of Florida’s IRB (IRB202200233 approved 24 February 2023 and IRB202401217 approved on 2 October 2024) and registered at ClinicalTrials.gov (NCT05766852 and NCT06580119). With a total sample of 39 female MSCPs, we investigated the effects of the novel Somatic Psychoeducational Intervention (SPI), grounded in Polyvagal Theory, on autonomic reactivity, psychological distress symptoms, and salivary oxytocin levels. Participants engaged in a three- to four-week intervention integrating psychoeducation, interoceptive training, breathwork, and somatic movement. A subset was randomly assigned via a random number generator to allow for comparison of the intervention group (n = 8) to control group (n = 7). Results. Repeated measures ANOVA revealed increases in salivary oxytocin (η_p² = 0.46) and reductions in autonomic reactivity (η_p² = 0.24) and psychological distress symptoms (η_p² ranging from 0.24 to 0.47). Benefits were sustained at one-month follow-up. Subset analyses focused on participants receiving the intervention at the same time found that only the participants in the intervention group improved with regard to autonomic reactivity and symptoms of anxiety and depression. Correlational analyses showed that changes in oxytocin and autonomic reactivity were associated with mindfulness improvements, which in turn predicted symptom reduction. Conclusions. These preliminary findings support SPI as a potentially scalable intervention with neurophysiological and psychological benefits. However, high attrition and small subgroup sizes necessitate cautious interpretation.

Background: Prior adversity may retune autonomic regulation and impede the ability to access a calm physiological state that would support mindful awareness, which is the facet of mindfulness focused on being present and accepting of the current moment. We investigated (1) how mindful awareness relates to cumulative adversity, autonomic reactivity, and current functioning; and (2) whether mindful awareness ameliorates the negative impact of cumulative adversity and autonomic reactivity on current functioning.Methods: Participants (N = 1,542; ages 18–88) reported living in the United States and experiencing at least one adversity. They completed online measures assessing their mindful awareness, cumulative adversity, autonomic reactivity, dysfunctional coping strategies, emotional distress, and PTSD symptoms.Results: Regression analyses revealed that the strongest predictor of greater mindful awareness was lower autonomic reactivity, which minimized the impact of cumulative adversity. Mediational analyses suggested that autonomic reactivity may mediate the relationship between cumulative adversity and mindful awareness. Regression analysis suggested higher autonomic reactivity remained the strongest predictor of poorer current functioning.Conclusion: Our research suggests that individuals with adversity histories may need to address both their mindful awareness and autonomic dysregulation to improve their current functioning.

Background/Objectives: Given that post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG) are separate constructs that can co-occur following adversity, we examined how prior adversity and current functioning difficulties may relate to the likelihood of meeting criteria for PTSD and scoring above the cutoff for PTG among individuals who reported being impacted by their prior adversity. Methods: Participants (n = 2112) in this international sample completed online measures assessing their adversity history, current functioning difficulties (i.e., negative world assumptions and autonomic reactivity), PTSD symptomatology, and PTG. Results: Chi square analyses suggested a trend toward an association between meeting criteria for PTSD and scoring above the cutoff for PTG, although not statistically significant (p = 0.061). Multivariable logistic regression analysis found that individuals most impacted by caregiver abuse and certain specific adversities (i.e., parent with a mental health problem, caregiver and non-caregiver sexual abuse, and being held captive) were more likely to meet the criteria for PTSD. Whereas those most impacted by life-threatening situations and the specific adversities of being impacted by a life-threatening illnesses or injury, were more likely to meet the criteria for PTG. However, the strongest predictor of the likelihood of PTSD was increased autonomic reactivity, and the strongest predictor of the likelihood of PTG was fewer negative world assumptions. Conclusions: Our research suggests the need to assess the perceived impact of adversity history, as well as the potential negative consequences of autonomic reactivity and negative world assumptions, as these may be associated with PTSD symptomatology and PTG.
