Participant Flow

A total of 364 Veterans were pre-screened. Flyers were posted at the VA and at the University of Houston; however, most of the people who responded had been contacted in Mental Health and Neurology clinics.

Of 364 Veterans pre-screened, 85 were invited to come in for further eligibility assessment for PTSD, mTBI, and exclusionary disorders. Of these, 33 did not attend or excluded themselves, leaving 46 enrolled. Of these, 9 dropped out before group assignment, and 15 dropped out post group assignment, leaving a total of 22 finishing the study.

PRIMARY outcome

Timeframe: 12 weeks

Population: One CAPS rater did not meet study criteria for expert CAPS administration; as a result, the CAPS data are not considered valid.

Changes in responses in the CAPS5 will be measured in patients following IRV meditation+mantra or ES education control.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 12 weeks and baseline

Population: The sample sizes here differ from those reported for other measures because these are the numbers of subjects who had MRI available and with acceptable quality assessment (i.e., not excluded because of excessive motion or sleepiness) for both time periods.

Functional connectivity was measured between the Default Mode Network (DMN) and lateral prefrontal cortex (LPFC), and between the amygdala and anterior cingulate. There were four seeds for the DMN (MPFC, PCC, left lateral parietal, right lateral parietal), and two seeds for the amygdala (right and left). Correlation coefficients representing the degree of connectivity between hypothesized regions were Fisher transformed. An a priori threshold of p\<.001 at the voxel level and p\<.05, FDR corrected for multiple comparisons across the whole brain, at the cluster level were used to determine significant connectivity.

SECONDARY outcome

Timeframe: 12 weeks and baseline

Population: The sample sizes here differ from those reported for other measures because these are the numbers of subjects who had completed the CRIS at both time periods.

Scores at baseline and 12 weeks in responses to the computerized version of the Community Reintegration in Service Members (CRIS-CAT) questionnaire in patients following meditation or control. There are three subscales: Extent of Participation (range 24-90), Perceived Limitations (range 33-99), and Satisfaction (range 34-91). Higher is better.

OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks, baseline

Population: The sample sizes here differ from those reported for other measures because these are the numbers of subjects who had completed PCL-5 at both time periods.

The PTSD Checklist 5 (PCL5) is a measure of PTSD symptoms based on DSM-V. The scores fall in the range 0-80; higher scores indicate worse outcome. We calculated the PTSD Checklist 5 (PCL5) difference score by subtracting the value at baseline minus the value at week 12. In this case higher scores represent a reduction in PTSD symptoms.

OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks, baseline

Population: The sample sizes here differ from those reported for other measures because these are the numbers of subjects who had PHQ-9 forms completed at both time periods.

The Patient Health Questionnaire-9 (PHQ-9) measure is a self-report measure of depression symptoms. Scores fall in the range 0-27; higher scores indicate worse outcome. This difference score denotes improvement in symptoms of depression. It was calculated by subtracting the value of PHQ-9 scores at baseline minus PHQ-9 scores scores at week 12.

POST_HOC outcome

Timeframe: 12 weeks

Population: The sample sizes here differ from those reported for other measures because these are the numbers of subjects who had MRI available and with acceptable quality assessment (i.e., not excluded because of excessive motion or sleepiness) for both time periods. Note that the sample sizes are identical to those reported in the secondary outcome section.

Within-group Post vs. Pre t-tests were done for each group with left and right hippocampal and parahippocampal gyrus (PHG) as seeds. Below are mean Fisher-transformed z scores and respective standard deviations of the Pearson's product correlation coefficients between the seed and cluster for each group. Positive mean z-scores scores reflect positive correlations between the seed and the cluster, and negative mean z-scores reflect negative correlations between the seed and the cluster. L IPL = left intraparietal lobule; VMPFC=ventromedial prefrontal cortex

POST_HOC outcome

Timeframe: 12 weeks

Population: Groups were combined to increase range of the sample size and to examine the general effect of therapy. Subjects (n=16; 9 IRV and 7 ES) were those who had both a post-therapy scan (regardless of therapy, IRV or ES) and CRIS-CAT scores prior to therapy.

The goal was to see if extent of participation in the community prior to therapy could predict the degree of functional connectivity between regions whose connectivity has been suggested to be part of a context processing network, disrupted during PTSD. The hippocampus was investigated because it is one of these regions. (The MPFC and thalamus are others.)
