This article reports on an empirical study of the psychosocial adaptation of international students in Ireland. Using measures of social support, loneliness, stress, psychological well-being, and sociocultural adaptation, data were obtained from international students and a comparison sample of Irish students. The study found that, although international students had high levels of social support and low levels of loneliness and stress, students were experiencing high levels of sociocultural adjustment difficulties and psychological distress. Significant differences invariables were reported across time, whereas differences between international and Irish students were also discovered. Suggestions for further research and for individuals working with international students are proposed. (Contains 3 tables.)
