This study investigated the differences between gender, Irish and migrants on life satisfaction, stress level and self-efficacy and the role of self-efﬁcacy on life satisfaction and stress. Sixty students, who included Irish and non-Irish, participated in the study using convenient sampling methods. Results revealed no significant differences between gender, Irish and migrants on life satisfaction, stress level and self-efficacy. A strong positive relationship was observed between self-efficacy and life satisfaction, however there was no significant interaction effect of self-efficacy and stress level.

The importance of self-efficacy found in this study was discussed.
