Abbreviations: Army STARRS, Army Study to Assess Risk and Resilience in Servicemembers; IRR, incident rate ratio.
Significantly different from the reference group (indicated by --) at the .05 level, two-sided test.
Based on a series of negative binomial equations controlling for version of the New Soldier Study, site of Basic Combat Training, service component, and all socio-demographic predictors listed here.
Parents college graduate=at least one parent completed college and the soldier had a lower level of education than college graduation; Parents some college=at least one parent completed some college and the soldier had a lower level of education.
