The role of posttraumatic stress and problem alcohol involvement in university academic performance.

OBJECTIVE: The present study examines how Posttraumatic Stress Disorder (PTSD) during the first year of university affects academic performance and whether alcohol behavior mediates the relationship between PTSD and poor academic outcomes.

METHOD: University students (N = 1,002; 65% female; Mage = 18.11) completed a baseline web survey, and 5 subsequent surveys throughout freshman year assessing variables of interest.

RESULTS: Mediation analyses were not significant; however, students who developed PTSD had a lower grade point average and experienced more alcohol consequences by the end of freshman year. Unremitted PTSD and alcohol consequences were associated with leaving university by year's end.

CONCLUSIONS: Findings suggest that assessment of trauma-related symptoms and alcohol behavior might benefit interventions aimed at students with academic difficulties.
