The 15-item Proactive Attitude Scale is defined as a unidimensional measure of belief in one's ability to effect positive life changes. The current study tested the scale's unidimensionality assumption with confirmatory factor analysis on a mixed sample of 157 fourth-year Bachelor of Education (n=30) and first year Masters of Education (n=121) students from The University of Hong Kong. 49 were men and 108 women, with a median age of 31 yr. The confirmatory factor analysis showed that a two-factor congeneric model fit the data significantly better than the unidimensional model. The two factors were characterized as reflecting proactive attitude and independent mindedness, respectively. The moderate correlation between these factors clearly defined them as reflecting distinct constructs, making untenable the scale's unidimensionality assumption.
15 项积极态度量表被定义为对个人实现积极生活改变能力信念的单维测量。本研究对香港大学 157 名四年级教育学士（n = 30）和一年级教育硕士（n = 121）学生的混合样本进行验证性因素分析，以检验该量表的单维性假设。其中 49 名男性，108 名女性，年龄中位数为 31 岁。验证性因素分析表明，双因素同构型模型对数据的拟合明显优于单维模型。这两个因素分别被表征为反映积极态度和独立思想。这些因素之间的适度相关性清楚地表明它们反映了不同的结构，使得该量表的单维性假设难以成立。
