Outcome Measures

Primary Outcomes (2)

  • Change in Sustained Attention to Response Task (SART)

    The SART is used to assess attentional performance and mind wandering (i.e., off-task thinking which is typically self-generated and compromises the performance of the task at hand). The task uses a continuous performance paradigm involving button presses to frequently presented non-targets (numbers 1, 2, 4, 5, 6, 7, 8, and 9) but requires the participants to withhold their motor response to the infrequent target (number 3). Withholding responses only to infrequent targets encourages a pre-potent response and mind wandering. Real-time subjective experience of mind wandering during SART is assessed through experience-sampling probes randomly presented throughout the task.

    Change from the pre-intervention baseline (testing 1) to the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

  • Change in Working Memory Task with Affective Distraction (WMDA)

    The WMDA is used to assess the ability to hold information in working memory while overcoming emotional reactivity and distraction. Specifically, participants are presented with a memory item that they need to memorize and hold in memory during a delay interval. During the delay, emotionally negative or neutral scene images are presented. The negative images are combat scenes from Iraq or Afghanistan and the neutral images are non-combat scenes.

    Change from the pre-intervention baseline (testing 1) to the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

Secondary Outcomes (18)

  • Change in Patient Health Questionnaire depression scale (PHQ)

    Change from the pre-intervention baseline (testing 1) to the immediate post-intervention (testing 2; either 2 weeks or 4 weeks according to the group) and the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

  • Change in Generalized Anxiety Disorder assessment (GAD-7)

    Change from the pre-intervention baseline (testing 1) to the immediate post-intervention (testing 2; either 2 weeks or 4 weeks according to the group) and the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

  • Change in PTSD Checklist_Military (PCLM)

    Change from the pre-intervention baseline (testing 1) to the immediate post-intervention (testing 2; either 2 weeks or 4 weeks according to the group) and the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

  • Change in the Pittsburgh Sleep Quality Index (PSQI)

    Change from the pre-intervention baseline (testing 1) to the immediate post-intervention (testing 2; either 2 weeks or 4 weeks according to the group) and the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

  • Change in Alcohol Use Disorders Identification Test-Consumption (AUDIT-C)

    Change from the pre-intervention baseline (testing 1) to the immediate post-intervention (testing 2; either 2 weeks or 4 weeks according to the group) and the long-term post-intervention (testing 3), which is an average of 8 weeks from the baseline.

Interventions

4-week MBATBEHAVIORAL

The training is known as Mindfulness-Based Attention Training, or MBAT. The MBAT program is based on the principles of Mindfulness-Based Stress Reduction, but contextualized for military personnel using themes relevant to military life. The training content is comprised of four central themes: concentration, body awareness, open monitoring, and compassion. This content will be delivered in 4, 2-hour sessions over 4 weeks. Participants will be assigned homework mindfulness practice during the interval of course delivery as well as for the few weeks following the end of the course.

Model Details: Participants will be assigned into three groups: (i) a 4-week MT group (MT4, n = 40) that will receive MBAT in 4, 2-hour sessions over 4 weeks; (ii) a 2-week MT group (MT2, n = 40) that will receive MBAT in 4, 2-hour sessions over 2 weeks; (iii) a no-training control group that will be tested before and after a no-training interval (NTC4, n = 40). After the end of the course sessions, participants from the training groups will still be assigned homework exercises until third testing session (T3). Hence, the MBAT program consists of delivery of the MBAT course, including homework mindfulness practice, and followed by an interval of homework mindfulness practice without course meetings. The design relies on group randomization at the level of individual military cohort units. This is due to the military requirement that organic unit structure can be maintained during testing and course session scheduling.
