Brief Summary

Background: Previous deployments like that to the Persian Gulf in 1991 produced veterans with post-deployment symptom-based health problems with no medical explanation. This was termed Gulf War illness or medically unexplained illness (MUI). If previous wars are any indication, some soldiers currently deployed to hostile areas also will return home with unexplained symptom-based illnesses. However, when this study began there was virtually no pre-war, prospective data on risk and resilience factors associated with MUI. This study is attempting to fill that gap. Objectives: Our goals are to: (a) determine pre- and immediate post-deployment factors predicting later MUI and poor functional status, (b) improve previous methodological problems (e.g., selection bias, recall bias and lack of baseline controls) in studies of MUI, and (c) relate pre-deployment risk factors (e.g., personality, stressor reactivity) and resilience factors (e.g., coping style, social support) to post-deployment functional status.

Outcome Measures

Primary Outcomes (4)

  • Non-Specific Physical Symptoms

    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.

    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)

  • Physical Functional Status

    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.

    pre-deployment (Phase 1), immediate post-deployment (Phase 2), 3 months post-return (Phase 3), 1 year post-return (Phase 4)

  • Mental Functional Status

    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.

    pre-deployment, immediate post-deployment, 3 months post-return, 1 year post-return

  • Health Care Utilization

    This variable is a sum score of the self-reported number of healthcare provider visits and emergency room visits in the prior 12 months.

    pre-deployment (Phase 1), immediate post-deployment (Phase 2), 3 months post-return (Phase 3), 1 year post-return (Phase 4)

The sample was comprised of only Army National Guard and Reserve military personnel, and therefore results may not generalize to the broader population of military personnel from other Service branches or components.
