This article explores the association between emotional intelligence, mental health, and English proficiency among college students. Survey results reveal that the gender ratio of college students is roughly equal, and the number of participants is stable each year. Humanities majors comprise 31% of the total. The authors collected data from nearly 1000 college students, which was analyzed using a matrix model. Results suggest that while there is a weak correlation between emotional intelligence scores and English grades, there is a strong correlation between mental health scores and English grades. The researchers conducted a 3-month psychological intervention experiment on 60 sophomore students. These students showed improvement in both mental health scores and English scores. Additionally, survey results indicate student satisfaction with the testing and psychological intervention. Overall, this study demonstrates that mental health and English proficiency are closely related, and psychological interventions can positively affect language skills.
