This paper explores the contribution of social identity change to international students' health and well‐being. International students typically face a range of challenges from the time they leave their home country, including the need to adapt both to a new culture and norms and to a new educational landscape. Previous research informed by the Social Identity Model of Identity Change (SIMIC) suggests that during such life transitions, an individual's group memberships and associated social identities can provide a buffer against the threats to well‐being that such transitions present. To examine the relevance of SIMIC for the transitions that international students' experience, semistructured interviews were conducted with 15 international students attending an Australian university. Thematic analysis provided support for the relevance of SIMIC's social identity gain and social identity maintenance pathways in the transition and revealed a number of associated factors that acted as either facilitators (e.g., a host family that supported community integration) or barriers (e.g., experiencing culture shock) to social identity change. These findings present the first qualitative support for SIMIC within an international student population and help to flesh out the specific ways in which social identity processes contribute to both positive and negative health and well‐being outcomes.

International students transitioning to university undergo dramatic changes in social identity, with a need to adapt to a new culture, language, environment, and way of living. This paper explores the impact of this social identity change on academic performance, academic retention, mental health, and life satisfaction. The Social Identity Model of Identity Change (SIMIC) predicts that during life transitions of this form, an individual’s group memberships and associated social identities can protect them from the negative effects of life change. This longitudinal study tested SIMIC among international students (N = 210) transitioning to study overseas, with data collected at three time points across a Foundation Year programme in a large Australian university. Consistent with SIMIC, continuity of social identities predicted higher academic performance and better life satisfaction, and indirectly predicted student retention over time.

International students typically face a range of challenges from the time they leave their home country, which includes the need to adapt to a new culture and norms and to a new educational landscape. Due to their unfamiliarity with local culture and language barrier, the stress of adjustment often leads them to feel lonely, socially isolated and homesick. However, the Social Publications during candidature
