“…SEM analyses showed that significant predictors of the Externalizing factor were gender (men had higher means on the latent variable), age (an inverse association), greater exposure to trauma, and exposure to combat trauma, specifically. This is consistent with prior research on the association between gender (Kramer, Krueger, & Hicks, 2008), age (Hurt & Oltmanns, 2002; Littlefield, Sher, & Wood, 2009) and externalizing psychopathology. The specificity of the relationship between combat exposure and externalizing was unexpected, however, and may be a function of the large percentage of male veterans in this sample.…”
