title: Individual augmentee deployment and newly reported mental health morbidity.
abstract: OBJECTIVE
  To investigate the association between US Navy individual augmentee (IA) deployers, who may lack the protective effects of unit cohesion and social support, and newly reported mental health.
  
  
  METHODS
  Responses from the Millennium Cohort Study questionnaires were examined for 2086 Navy deployers in this prospective exploratory study. Multivariable logistic regression was used to evaluate IA deployment and newly reported mental health symptoms.
  
  
  RESULTS
  After adjusting for covariates, IA deployment was not significantly associated with newly reported posttraumatic stress disorder (odds ratio = 1.02; 95% confidence interval: 0.53-1.95) or mental health symptoms (odds ratio = 1.03; 95% confidence interval: 0.66-1.60) compared with non-IA deployment.
  
  
  CONCLUSIONS
  IA deployment was not associated with increased risk for posttraumatic stress disorder or mental health symptoms following deployment. It is likely that social isolation was not highly influential among Navy IAs in this study.
