How Studying Abroad Affects Mental Health: A Data-Driven Analysis

Introduction

Studying abroad can be a transformative experience, but it also brings unique mental health challenges. Using a 2018 survey dataset from a Japanese international university, this project analyzes the psychological impact of studying in a foreign country. Leveraging SQL, Python (Pandas, SQLAlchemy), and data visualization tools, I explored how factors like social connectedness, acculturative stress, and length of stay correlate with depression—and why international students may face higher risks.

Key Findings at a Glance

1. Higher Depression Scores

   1. International students averaged 8.5/25 on the PHQ-9 depression scale, compared to 8.0 for domestic students.

2. Social Connectedness Matters

   1. A strong negative correlation (-0.54) between social ties and depression for international students.

3. Acculturative Stress Plays a Role

   1. Stress levels showed a moderate positive correlation (0.41) with depression for international students.

4. Length of Stay Has Mixed Effects

   1. Depression scores fluctuated for international students over time, peaking after 6+ years.

Methodology: SQL & Python in Action

Tools Used

• Data Extraction: Kaggle API

• Analysis: SQLAlchemy, Pandas

• Visualization: Matplotlib, Seaborn

SQL Queries for Insights

I ran targeted SQL queries to compare international and domestic students:

Example: Social Connectedness vs. Depression

Result: International students with lower social connectedness averaged 20% higher depression scores.

• As social ties strengthen, depression scores drop, especially for international students.

Acculturative Stress Impact

• Higher stress = Higher depression, with international students most affected.

Actionable Recommendations

1. For Universities:

   1. Expand peer mentorship and cultural integration programs

   2. Offer targeted counseling for long-term international students.

2. For Students:

   1. Prioritize building social networks early.

   2. Use stress-management resources (e.g., workshops, mindfulness apps).

Future Research Directions : To deepen these insights, future studies could explore:

• The role of language proficiency in stress levels.

• How extracurriculars (e.g., clubs, sports) mitigate depression.

• Longitudinal tracking of mental health trends.

Conclusion

Data reveals a clear need for tailored mental health support for international students. By addressing social isolation and acculturative stress, universities can foster healthier, more inclusive environments—turning challenges abroad into opportunities for growth.
