Objective: To explore the relationship between self-esteem, perfectionism
and social anxiety, and to provide scientific evidence for improving college students'
social anxiety and promoting mental health. Methods: 229 undergraduate students
were randomly selected in a convenient sampling manner. The subjects were tested
by the Chinese frost multidimensional perfectionism scale, self-esteem scale, and
interaction anxiousness scale. Results: The non-adaptive perfectionism of males was
significantly higher than that of females. There was a significant positive correlation
between non-adaptive perfectionism and social anxiety, and a significant negative
correlation with self-esteem. Moreover, there was a significant negative correlation
between social anxiety and self-esteem. Self-esteem plays a partial mediating role in
the relationship between non-adaptive perfectionism and social anxiety. The mediating
effect accounts for 20% of the total effect. Conclusion: Non-adaptive perfectionism,
self-esteem, and social anxiety are closely related. Self-esteem plays a partial mediating
role in the influence of non-adaptive perfectionism on social anxiety.
