Objective:To investigate the interpersonal attribution style,self-efficacy of the baccalaureate female nurs-ing students(BFNS) and to explore the relationship between attribution style and self-efficacy.Methods:113 BFNS from Hainan Medical College were investigated by the Interpersonal Relationship Subscale of Multidimensional-Multiattribu-tional Causality Scale by Lefcourt et al and the General Self-Efficacy Scale(GSES) by Ralf Sehwarzer.Results:The Inter-personal Relationship Attribution Score(IRAS) of BFNS was 41.02?11.38.There was no statistical difference in IRAS be-tween two grades(t=0.899,P=0.371).The BFNS's attribution sequence was ranked as effort,fortune,ability,and back-ground under the condition of interpersonal communication success;while it was fortune,ability,effort,background under the condition of failure.There was statistically significant difference between scores of GSES and the normal(t=-10.212,P= 0.000).Pearson correlation analysis showed that there were positive correlations between the self-efficacy and interperson-al attribution style.Conclusion:When the female nursing students' behavior is successful,there is show more tendency to internal attribution.On the contrary,when they fail,there is more tendency to external attribution.Self-efficacy interacts with interpersonal attribution style.
