Project: Analyzing Students' Mental Health
Does going to university in a different country affect your mental health? A Japanese international university surveyed its students in 2018 and published a study the following year that was approved by several ethical and regulatory boards.
The study found that international students have a higher risk of mental health difficulties than the general population, and that social connectedness (belonging to a social group) and acculturative stress (stress associated with joining a new culture) are predictive of depression.
We'll explore the students data using PostgreSQL to find out if we would come to a similar conclusion for international students and see if the length of stay is a contributing factor.
| Field Name | Description |
|---|---|
inter_dom | Types of students (international or domestic) |
stay | Current length of stay in years |
todep | Total score of depression (PHQ-9 test) |
tosc | Total score of social connectedness (SCS test) |
toas | Total score of acculturative stress (ASISS test) |
