About this study

Official title: The Impact of Mindfulness-Based Resilience Training on Stress-Related Biological, Behavioral, and Health-Related Outcomes in Law Enforcement Officers

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.

Read the detailed description

120 police officers will be recruited from Dane County law enforcement agencies to take part in an 8-week, group-based, mindfulness-based training program called Madison Mindfulness-Based Resilience Training (mMBRT). Officers will be randomized to an active group, which will receive mMBRT immediately after baseline assessments, and a waitlist control group, which will receive mMBRT after a post-intervention assessment and a subsequent follow-up assessment. mMBRT is similar to and inspired by MBRT, and both of these programs are law enforcement-specific interventions based on Mindfulness-Based Stress Reduction (MBSR), a commonly used mindfulness program in many healthcare settings. mMBRT is structurally similar to MBSR, with 8 weekly 2-hour classes involving guided meditation practices, gentle movement, and group-based discussion (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). Participants will be provided with weekly homework assignments and audio recordings that provide guided instruction in various meditation and yoga practices.

At three separate timepoints, officers will take part in a laboratory assessment that involves the following procedures:

  • administration of computerized behavioral tasks
  • completion of self-report questionnaires that assess trauma history and occupational stressors, perceived stress, sleep, physical and mental health
  • collection of a small amount of blood via finger prick and/or venipuncture (to assess peripheral inflammatory markers)
  • collection of a small amount of hair from the scalp (to assess hair cortisol concentration)
  • measurement of height and weight for the assessment of body mass index, and for use with activity trackers data

In conjunction with these laboratory assessments, data will be collected from officers in the field over the course of approximately 1 week (coinciding with a regularly scheduled work week), including the following procedures:

  • officers will wear an activity monitor (e.g., Fitbit) to allow for objective monitoring of sleep quality and resting heart rate throughout the study
  • officers will collect saliva samples 4 times per day over 3 days for the assessment of salivary cortisol
  • officers will complete daily logs of work hours, types of events encountered during work, perceived stress related to these events, and self-reported mood and affect ratings

These field data will be related to dispatch records, which will provide objective information regarding the types of incidents responded to, and the time and location of these incidents.

The laboratory and field assessments will be collected at baseline (prior to randomization); after the active mMBRT group completes the intervention; and at a follow-up visit (approximately 4 months after the end of the intervention), after which the wait-list group will be offered the intervention.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • mMBRTBehavioural

    Also called Madison Mindfulness-Based Resilience Training, MBRT

    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.

Study groupRoleWhat they receive
mMBRTExperimentalIndividuals 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).
Receives: Behavioral: mMBRT
Waitlist control groupNo interventionIndividuals 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Baseline, post-intervention (3 months)

  2. 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.

    Measured: Baseline, post-intervention (3 months)

Secondary outcomes (5)
  1. Change in cortisol awakening response

    The cortisol awakening response (CAR) will be measured using saliva samples collected 0, 30, and 45 minutes after awakening on each of 3 days, with hypothesized increased CAR in the intervention vs. waitlist group at post-intervention (3 months) vs. baseline.

    Measured: Baseline, post-intervention (3 months)

  2. Change in peripheral inflammatory markers

    Composite of hsCRP and 4-plex of pro-inflammatory cytokines (IL-6, IL-8, IL-10, TNF-alpha) is hypothesized to be lower in intervention vs. waitlist group at post-intervention (3 months) vs. baseline.

    Measured: Baseline, post-intervention (3 months)

  3. Change in hyperarousal symptoms

    Change in hyperarousal symptoms from the PTSD Checklist for DSM-5 at post-intervention (3 months) vs. baseline

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

  4. Change in subjective sleep quality

    Global scores on the Pittsburgh Sleep Quality Index (Buysse et al., 1988) will be compared at post-intervention (3 months) vs. baseline

    Measured: Baseline, post-intervention (3 months)

  5. Change in perceived stress

    Changes in total scores from the Perceived Stress Scale (10-item version; Cohen et al., 1988) from baseline to 3 months.

    Measured: Baseline, post-intervention (3 months)
