Autonomic Modulation Training for Police Exposed to Post-Traumatic Stress Injuries : Autonomic Modulation Training: A Biological Approach to Building Resilience and Wellness Capacity Among Police Exposed to Post-Traumatic Stress Injuries (PTSI)

HypothesesSelf-reported PTSI symptoms and resilienceH1. Symptoms of PTSI will be significantly reduced following completion of the AMT intervention, as measured by the Personal Health Questionnaire (PHQ-8), General Anxiety Disorder Scale (GAD-7), Depression, Anxiety, and Stress Scale (DASS), PTSD checklist (PCL-5), Copenhagen Burnout Inventory (CBI), Perceived Stress Scale (PSS), Alcohol Use Disorder Identification Test (AUDIT). Occupational/operational stress exposure will be measured by the Police Stress Questionnaire (PSQ) to account for possible exposures to stress and potentially traumatic events over the course of the intervention. Self-reported and COVID related stress will also be evaluated.H2. Functional wellness capacity and resilience will be significantly improved following completion of the AMT intervention, as measured by the Brief COPE, Resilience Scale for Adults (RSA-33), and Brief Resilience Scale (BRS), White Bear Suppression Inventory (WBSI), Perseverative Thinking Questionnaire (PTQ), Ultra-Brief Penn State Worry Questionnaire (UB-PSWQ), Ultra-Brief Rumination Response Styles (UB-RRS), Good Health Practices Scale (GHPS).H3. Sex and gender differences in PTSI will be observed at baseline and post-intervention assessment. We expect that females will report more symptoms of PTSI and lower resilience at baseline, and a greater reduction of PTSI symptoms and greater increase in resilience at follow-up than males. Gender role stress, discrimination, and harassment will be explored as moderators of PTSI symptoms at baseline and in response to the AMT intervention. Sex is measured by self-reported sex at birth, gender discrimination is measured by Workplace Gender Discrimination Scale (WGDS) and harassment is measured by the Gender Experiences Questionnaire (GEQ).Objective biological indicators of PTSI symptoms and resilienceH4. Resting HRV will significantly increase following completion of the AMT intervention. Changes in resting HRV will be measured by time and frequency domain parameters based on data collected from the wearable HR monitors (e.g., high and low frequency HRV, LF/HF ratio, and the root mean square of successive differences (RMSSD) as recommended in the standards of practice for HRV analysis.H5. RSA will significantly increase following completion of the AMT intervention. RSA is measured by obtaining the respiratory frequency. Greater power at the respiratory frequency indicates a higher level of RSA and will be analyzed using the gold standard HRV analysis program, Kubios.H6. Recovery from acute stress will significantly improve following completion of the AMT intervention. Acute stress will be induced by completion of the online Paced Auditory Serial Addition Test (PASAT) and the Stroop Emotion Face Interference Task. Acute stress recovery will be assessed via a time domain measure of HRV (RMSSD).H7. Based on inconsistencies in the extant literature, we will conduct exploratory analyses of any potential sex and gender differences in HRV, RSA, and acute stress recovery at baseline and post-intervention assessments. Although we expect to see improvements in self-reported and objective measures of PTSI and resilience overall (i.e., independent of sex and gender), we hypothesize that gender role stress and gender discrimination will moderate these effects. Further, it is possible that the magnitude of post-intervention changes is greater among women given the additional burden of exposure to a hyper-masculinized working environment. Because AMT provides tools for effective stress management, women may find more benefit from the intervention in managing the wider array of sociocultural stressors they experience compared to males..
