NCT03488875

Brief Summary

In a sample of 120 officers from Dane County law enforcement agencies, the investigators are conducting a randomized controlled trial of an 8-week mindfulness-based training program for police officers, Madison Mindfulness-Based Resilience Training (mMBRT), and investigating the impact of this training on subjective responses to stress, stress-related psychological and physical health outcomes, and biological and behavioral correlates of perceived stress. While the benefits of mindfulness-based interventions have been documented in a variety of populations, this will be the largest and most comprehensive study of its kind of law enforcement personnel. In addition to self-report measures, this study assesses an array of objective biological and behavioral outcomes both in the laboratory and in the field that may speak to mechanisms of change involved in symptom reduction.

Outcome Measures

Primary Outcomes (2)

  • Change in perceived occupational stress

    Change in combined scores of perceived operational and organizational stressors from the Police Stress Questionnaire (McCreary \& Thompson, 2004) from baseline to 3 months. Each of these 2 scales has 20 items with 1-7 ratings, where higher scores indicate greater stress (1=no stress at all, 7=A lot of stress). Organizational and operational stress scales will be summed to create a single value with a range of 40-280.

    Baseline, post-intervention (3 months)

  • Change in diurnal cortisol slope

    Saliva samples collected on each of 3 days will be used to calculate diurnal cortisol slope, defined as the change between the peak cortisol response in the 45 minutes after awakening and cortisol levels just prior to bedtime, with a hypothesized steeper slope in the intervention vs. waitlist group at post-intervention (3 months) vs. baseline.

    Baseline, post-intervention (3 months)

Secondary Outcomes (5)

  • Change in cortisol awakening response

    Baseline, post-intervention (3 months)

  • Change in peripheral inflammatory markers

    Baseline, post-intervention (3 months)

  • Change in hyperarousal symptoms

    Baseline, post-intervention (3 months), follow-up (6 months)

  • Change in subjective sleep quality

    Baseline, post-intervention (3 months)

  • Change in perceived stress

    Baseline, post-intervention (3 months)

Other Outcomes (12)

  • Change in hair cortisol concentration

    Baseline, follow-up (6 months)

  • Change in restful minutes of sleep

    5-7 nights of sleep will be monitored at baseline and post-intervention (3 months)

  • Change in behavioral pattern separation ability

    Baseline, post-intervention (3 months)

  • +9 more other outcomes

Study Arms (2)

mMBRT

EXPERIMENTAL

Individuals in the mMBRT group will receive an 8-week mindfulness-based intervention in groups of approximately 15 individuals in 8 weekly 2-hour classes (one of these classes, toward the end of the course, is approximately 4 hours and integrates many of the practices and teachings covered throughout the training program).

Behavioral: mMBRT

Waitlist control group

NO INTERVENTION

Individuals in the waitlist control group will complete the same assessments as those in the active treatment group, but will not be offered any intervention until the conclusion of the trial. At this time, control group participants will be offered the intervention.

Interventions

mMBRTBEHAVIORAL

Madison Mindfulness-Based Resilience Training (mMBRT) is an 8-week mindfulness-based intervention developed specifically for police officers, which is similar to and inspired by a program developed by researchers at Pacific (OR) University (Christopher, Goerling et al., 2016). mMBRT includes 8 weekly 2-hour classes involving guided meditation practice, gentle movement, and group-based discussion (the 7th class is a longer, 4-hour class). The total class time is about 18 hours over 8 weeks, and participants are asked to engage in home practice for up to 30 minutes/day, 6 days/week throughout the intervention.

Masking Details
Participants cannot be made blind to study assignment due to the nature of the intervention. Baseline (T1) measures will be collected prior to treatment assignment. Every effort will be taken to minimize knowledge of group assignment by the study team, in particular the PI and other individuals involved in data analysis; however, the small size of the study team and overlapping roles of team members may preclude masking of group assignment for all members of the study team.
