As a special group of vocational college students, psychological and behavioral problems of fiveyear
vocational student are closely related to their social support system, and their mental health level
deserves extensive attention. In this study, the Social Support Rating Scale was used to measure 452 fiveyear
vocational students in a vocational college. The results showed that the social support level of fiveyear
vocational students was slightly higher than the medium level, but the objective support level was
slightly lower than the medium level.There are significant gender differences in students’ social support
and all dimensions. Only children and non-only children also have significant differences in social
support and all dimensions. Students from different grades and places of origin do not have significant
differences in social support and all dimensions. Therefore, based on the social support of five-year
vocational students, vocational colleges should carry out targeted mental health education to improve
work efficiency.
