Trial Outcomes & Findings for Yoga and Physical Activity for Veterans (NCT NCT03509909)

NCT ID: NCT03509909

Last Updated: 2024-11-21

Results Overview

Semi-structured clinical interview assessing severity of PTSD symptoms administered by a trained, blinded assessor. The range of scores is 0-80. Mpre-Mpost is presented, so positive numbers indicate a reduction in PTSD symptom severity from before to after the intervention.

PRIMARY outcome

Timeframe: Baseline to post-treatment (approx 12 weeks)

Population: Differs from the total population due to missing data. Includes individuals with both time points because of the nature of the change score.

Semi-structured clinical interview assessing severity of PTSD symptoms administered by a trained, blinded assessor. The range of scores is 0-80. Mpre-Mpost is presented, so positive numbers indicate a reduction in PTSD symptom severity from before to after the intervention.

Self-report measure of depressive symptoms with a range of 0-27. Mpre-Mpost is presented, so positive numbers indicate a reduction in depression severity.

Population: Differs from the total population due to missing data. Includes individuals with both time points because of the nature of the change score.

Self-report measure of anger with three major subscales (state anger, trait anger and anger control index), which are quantified as T-scores (i.e., 50 indicates the population mean with a standard deviation of 10), calculated from published adult norms tables. Change in T-scores, Tpre-Tpost, is presented, so positive numbers indicate a reduction in anger.

Population: Differs from the total population due to missing data. Includes individuals with both time points because of the nature of the change score. Loss of data increased as scale is invalid if all items are not answered.

Self-report measure of pain interference, reported as a T-score (i.e., 50 indicates the population mean with a standard deviation of 10) calculated from published adult norms table. Change in T-scores, Tpre-Tpost, is presented, so positive numbers indicate a reduction in pain interference.
