The present study was designed to determine the number and nature of factors involved in Rotter's I-E Scale and to examine the question of the multidimensionality of the scale. Subjects were 329 college undergraduates. Principal components analysis was performed on the 23 pertinent items of the scale, followed by Varimax rotation. Multiple criteria indicated a 10-factor solution which accounted for 61% of the total variance. The first two factors were strongly similar to those reported previously. Results support Rotter's (1975) contention that subclasses within the scale will vary from sample to sample.

Rotter轨迹控制量表的多维性和因子结构的进一步考虑

本研究旨在确定 Rotter IE 量表中涉及的因素的数量和性质，并检查量表的多维性问题。受试者为329名大学本科生。对量表的 23 个相关项目进行主成分分析，然后进行 Varimax 旋转。多个标准表明一个 10 因子解决方案占总方差的 61%。前两个因素与之前报道的非常相似。结果支持 Rotter (1975) 的论点，即量表内的子类会因样本而异。
