以216名初中二年级学生为被试，采用现场实验，探讨个体创意自我效能感在竞争、评价和时间三种压力情境下对创造力的影响。结果发现，三种压力对于总体创造力的影响不同；时间、评价压力分别提高了流畅性和新颖性，竞争压力既提高了流畅性又提高了新颖性，但三种压力情境都降低了变通性；创意自我效能感中间组的学生在压力情境下具有最好的变通表现，而效能感低分组表现最差。

The aim of this study is to explore the effect of creative self-efficacy (a very important component of personality) on different aspects of creativity under time pressure, competence pressure and evaluation pressure. Data were collected from 216 students among 3 classes in a middle school. The main results of the study are as follows: The effects of pressure on total creativity were, competence- enhanced, evaluation- decreased, time-no significant effect. Specifically, time pressure mainly enhanced fluency; evaluation pressure mainly enhanced originality; competence pressure enhanced both; the three pressure contexts all decreased flexibility significantly. There are significant differences on the change of flexibility among students with different creative self-efficacy under pressure contexts. Namely, students with middle score on creative self-efficacy have the least decline and those with lowest score on creative self-efficacy have the most.
