  • *Significant at p≤0.05.

  • †Significant at 0.05<p≤0.10.

  • ‡A variable-reduction strategy was used with each logistic regression. Seven outcomes were assessed and the retained covariates were not necessarily the same for each outcome.

  • §One of the perceived sufficiency of care outcomes for medication services (ie, ‘need at least partially met versus not’) could not be assessed using logistic regression due to the very low fraction of reserve force personnel who indicated that this need was not met (ie, <0.5% compared with 4.4% for regular force personnel).

  • LTE, lifetime exposure to potentially traumatic experiences; RegF, regular force; ResF, reserve force.
