Writing Anxiety Scale and the self-designed tutors’ guidance rating index. Results: 1. Undergraduate
thesis writing self-efficacy significantly negatively predicts graduation thesis writing anxiety (β=-0.132,
t=-2.534, p<0.05). The higher the writing self-efficacy, the lower the writing anxiety. 2. The tutor’s guidance
has a moderating effect on the relationship between Undergraduate thesis Writing Self-efficacy Quadratic
Term and writing anxiety (β=0.176, t=3.376, p<0.01, ΔR2= 0.027). Conclusion: The predictive effect of
undergraduate thesis self-efficacy on writing anxiety is moderated by the level of the tutor’s guidance.
Strengthening the self-efficacy of undergraduate thesis writing and improving the guidance level of tutors
