Student service members/veterans represent a growing population on college campuses. Despite this growth, scholarly investigations into their health- and adjustment-related issues are almost nonexistent. The limited research that is available suggests that student service members/veterans may have trouble connecting with their civilian counterparts and be at risk for social isolation. The present study compared the development and implications of emotional support from peers among 199 student service members/veterans and 181 civilian students through 3 distinct occasions over the course of 1 calendar year. Data were collected via electronic survey. Measured constructs included perceived emotional support from university friends, mental health, alcohol use, and academic functioning. A series of multilevel models revealed that student service members/veterans reported less emotional support from their peers compared with their civilian counterparts; yet, emotional support from peers increased similarly for both groups over time. Although, increasing peer emotional support was generally related to better academic and mental health outcomes for both groups, the links between emotional support and mental health were stronger for civilian students. Results suggest that mental health practitioners, particularly those on college campuses, should be prepared to deal with veteran-specific experiences that occur before and during college.
