Not Applicable

Completed

Conditions: Stress, Psychological
Aggression

Interventions: Behavioral: Mindfulness-Based Resilience Training
Behavioral: Stress Management Education

Registration Number: NCT03784846

Lead Sponsor: Pacific University

Brief Summary: Law enforcement officers (LEOs) are exposed to significant stressors, elevating their risk for aggression and excessive use of force, as well as mental health consequences, including post-traumatic stress disorder, burnout, alcohol misuse, depression, and suicide. The proposed study will identify, optimize and refine best clinical and research practices across two sites to ensure success in a future multisite efficacy trial assessing preventative effects of Mindfulness-Based Resilience Training on physiological, behavioral, and psychological outcomes.

Detailed Description: Law enforcement officers (LEOs) are exposed to significant stressors, elevating their risk for aggression and excessive use of force. Such dysfunctional stress reactivity can lead to devastating consequences for their community, including unjustified shootings, severe beatings, and fatal chokings. It can also lead to serious consequences for the LEOs, including elevated incidence of post-traumatic stress disorder, burnout, alcohol misuse, depression, and suicide. A recent meta-analysis of LEO stress reduction programs found little evidence to demonstrate that such approaches are effective, highlighting the urgent need for preventive interventions targeting the stress inherent to policing. Mindfulness training is a promising approach with high-stress populations that has been shown effective in reducing stress and increasing resilience. In a recent pilot feasibility study (R21AT008854), the study team established initial feasibility, acceptability, and adherence to procedures in a single-site RCT assessing Mindfulness-Based Resilience Training (MBRT), a preventive intervention designed to improve LEO mental health and resilience, and reduce aggression and excessive use of force. The R21 data suggest physiological mechanisms and potential clinical benefit in a sample of LEOs. Relative to waitlist control, MBRT participants showed improvements in stress reactivity, aggression, burnout, occupational stress, sleep disturbance, and psychological flexibility. Implemented at two sites, the proposed study is designed to establish optimal protocols and procedures for a future full-scale, multi-site trial assessing effects of MBRT versus an attention control (Stress Management Education) and a no-intervention control, on physiological, behavioral, and psychological outcomes. To prepare for this future clinical trial, this study will: a) enhance efficiency of recruitment, engagement and retention; b) optimize lab, assessment, and data management procedures; c) optimize intervention training and ensure fidelity to intervention protocols; and d) assess participant experience and optimize outcome measures across sites. The long-term objective of this line of research is to develop an intervention that will reduce violence and increase resilience among LEOs, as well as yield significant benefits for communities and residents they serve.

Arm && Interventions

Group	Intervention	Description
Mindfulness-Based Resilience Training	Mindfulness-Based Resilience Training	MBRT is an 8-week program combining training in standardized mindfulness practices targeting factors that facilitate resilience, cognitive behavioral therapy (CBT), and psychoeducation. It contains experiential and didactic exercises including body scan, sitting and walking meditation, mindful movement and discussions.
Stress Management Education	Stress Management Education	SME was designed as an active control condition for other mindfulness-based intervention trials. SME uses a group-based didactic approach with modules on physiological and dietary effects of stress, time management, sleep physiology and insomnia, nutrition, exercise, stress hardiness, and factors mitigating impacts of stress.

Primary Outcome Measures
