“…Service members are at greater risk for problems with alcohol and other substances than civilians (Bray, Brown, & Williams, ; Green, Beckham, Youssef, & Elbogen, ; Hoopsick, Fillo, Vest, Homish, & Homish, ; Jacobson et al, ; Milliken, Auchterlonie, & Hoge, ; J. L. Thomas et al, ). Further, there is an abundance of literature demonstrating the effects of deployment on mental health and substance use outcomes among service members (Bray & Hourani, ; Hassija, Jakupcak, Maguen, & Shipherd, ; Jacobson et al, ; Larson, Mohr, Jeffery, Adams, & Williams, ; Milliken et al, ; Renshaw, Rodrigues, & Jones, ; M. M. Thomas, Harpaz‐Rotem, Tsai, Southwick, & Pietrzak, ; Vest, Heavey, Homish, & Homish, ; Vest, Homish, Hoopsick, & Homish, ). Thus, negative social interactions or experiences may contribute to even greater risk for substance use among this already high‐risk group.…”
