University support services can be a beneficial resource for students coping with personal stressors. This study investigated the predictors of service use by undergraduate students during their first year at university. Participants completed self-report measures of problem-solving effectiveness, psychological distress and perceived social support (availability and satisfaction) at the start of the academic year, frequency of exposure to stressors half-way through the first semester and support service use at the end of the first and second semesters. Perceived availability of social support and frequency of exposure to stressors predicted service use. Additional analyses examined change in psychological distress across the first semester. Implications of these findings are discussed.
