Trial Outcomes & Findings for Prospective Study of Veteran Health in Previously Deployed Soldiers (NCT NCT00285246)

NCT ID: NCT00285246

Last Updated: 2015-05-12

Results Overview

Severity of non-specific physical symptoms from the 15 item Patient Health Questionnaire-15 (Kroenke, Spitzer \& Williams, 2002). Scale score range is 0-30. Higher scores indicate greater non-specific physical symptom severity. This scale does not contain subscales.

PRIMARY outcome

Timeframe: pre-deployment (Phase 1), immediately post-deployment (Phase 2), 3 months post-return from deployment (Phase 3), 1 year post-return from deployment (Phase 4)

Population: Not all of the 790 completers has complete data on the non-specific physical symptoms measure.

Severity of non-specific physical symptoms from the 15 item Patient Health Questionnaire-15 (Kroenke, Spitzer \& Williams, 2002). Scale score range is 0-30. Higher scores indicate greater non-specific physical symptom severity. This scale does not contain subscales.

Population: Not all of the 790 completers has complete data on this physical functional status measure.

Physical Component Summary Score (PCS) from the Veterans RAND (VR) 36 measure (Kazis, 2000). Composite scores are normed to a mean of 50 and a SD of 10. Scores can range from 0-100. Higher scores indicate better physical function.

Population: Not all of the 790 completers has complete data on the mental functional status measure.

Mental Component Summary Score (MCS) from the Veterans-RAND (VR) 36 (Kazis, 2000). MCS is a composite score with a mean of 50 and a standard deviation of 10. Scale scores range from 0-100 with higher scores reflecting better mental function.
