Abstract：Based on the mental health test with Symptom Checklist 90 ( SCL-90) given to freshmen at H university in 2011, 2012, and 2013, the author finds the following facts by analyzing data, contrasting and individual interview: the proportion of male students with positive result is significantly higher than that of females; the psychological problems of male students are mainly obsessive compulsive disorder, social contact sensitivity, and about 70% male students with positive result are confronted with target deletion and social contact confusion; professional satisfaction has a significant effect on the mental health of male students. Given problems mentioned above, the author analyzes family, society and cognition factors, and suggests that practical psychological assistance, guidance and education ( such as studentteacher communication, group counseling and professional education) should be provided from the perspective of life education.
