International students represent a significant portion of the global higher education population, yet their mental health experiences are often studied in isolation. This systematic literature review synthesizes 86 peer-reviewed studies to map the diverse factors influencing the mental well-being of these students. By applying the PRISMA guidelines and an ecological framework, the authors categorize these influences into individual, relational, institutional, and structural domains.
The review identifies nine primary, interconnected themes that impact international students:
The authors emphasize that these factors do not act in isolation; rather, they interact across different levels of the student's environment. For instance, structural issues like visa policies can exacerbate individual financial stress, which in turn impacts a student's ability to engage in social support networks.
A critical observation of this review is the current state of the literature: over 82% of the analyzed studies rely on quantitative methodologies, and nearly 60% are focused on English-speaking countries. This concentration leaves a significant gap in our understanding of the lived experiences of students in more diverse geographic regions. The authors argue that future research must move toward longitudinal, mixed-methods designs to better capture the dynamic nature of student well-being over time and across different cultural contexts.
Understanding these factors is essential for universities and policymakers to move beyond generic support services. By recognizing the intersection of structural, institutional, and personal stressors, institutions can develop more targeted, holistic interventions that address the specific needs of international students, ultimately fostering a more inclusive and supportive academic environment.
International students constitute a substantial proportion of the global tertiary education population, yet the factors impacting their mental well-being remain fragmented across the literature. This systematic review synthesizes peer-reviewed studies to identify key factors that impact international students’ mental well-being and address research gaps. Using the PRISMA guidelines and the PICo tool, 86 studies were selected through a comprehensive search of eight databases. The findings indicate that more than 82% of the studies used quantitative methods and that more than 59% were conducted in English-speaking countries. Thematic analysis revealed nine interconnected factors impacting mental well-being: personal and psychological issues; sociocultural adjustment and acculturative stress; social support and belongingness; academic pressure; language and communication challenges; racism and xenophobia; visa policy-related stress; and housing and living conditions and financial pressure. Using an ecological framework, the results emphasize interactions among individual, relational, institutional, and structural determinants. This review underscores the need for longitudinal, mixed-methods research with greater geographic diversity to inform policy and practice.
Sam: [steady, grounded] International students do not experience mental health challenges as isolated failings, but as emergent properties of a multi-layered ecosystem where structural policies, like visa delays, cascade into individual distress. That is the core conclusion of a systematic literature review by Ishwar Koirala and colleagues.
Alex: [leaning in, curious] That sounds like a shift from the traditional focus on individual resilience. Are they suggesting the literature has been missing the forest for the trees by treating these students as a monolithic group?
Sam: [measured, teaching mode] Exactly. By synthesizing eighty-six studies, the authors map stressors across four levels: individual, relational, institutional, and structural. <break time="0.6s" /> The load-bearing finding is that distal factors—like immigration policy—act as the primary drivers that trigger proximal issues like academic anxiety.
Alex: [analytical, processing] So, if a student is struggling, the traditional approach looks for a lack of study skills, but this framework argues we should be looking at the structural layer, like visa instability, as the actual root cause?
Sam: [nodding in voice, precise] Precisely. The authors found a clear ripple effect. A change in a structural factor, such as a shift in work-hour regulations, immediately alters the relational layer by reducing time for social support, which then degrades the individual’s mental well-being.
Alex: [pace picking up slightly, probing] If the field is so fragmented, how did they handle the heterogeneity in the data? If eighty-two percent of these studies are quantitative, they must be measuring these stressors in very different ways.
Sam: [steady, matter-of-fact] They used PRISMA guidelines and the PICo tool to standardize their inclusion criteria, allowing them to aggregate findings into a unified thematic map. However, a careful referee would point out that because fifty-nine percent of the studies were conducted in English-speaking countries, the model might be biased toward Western educational systems.
Alex: [deliberate, checking understanding] So the framework is robust, but the geographic distribution limits its generalizability to non-Western contexts?
Sam: [thoughtful, acknowledging the point] That is the primary limitation. We have a solid diagnostic map, but we are still missing the longitudinal data to predict how these stressors evolve over the entire duration of a student's degree. If you want to see how they mapped these specific interactions, check out the paper linked in our show notes.
