项目表述效应对句子式大五人格量表的影响

The Influence of Item Wording Effect on the Sentence Big Five Personality Inventory

由正、反向题所带来的项目表述效应会引起研究结果的偏倚,而在国内自编的句子式大五人格量表中尚缺乏对该效应的检验、控制。采用相关特质相关法(CTCM)对句子式中国大五人格量表简版CBF-PI-B进行项目表述效应检验,评估该效应对其测量模型的影响,并分析了特质乐观与正、反向题方法因素的关系。结果显示:CBF-PI-B中同时存在正、反向题项目表述效应,其对宜人性、严谨性、外向性、开放性维度的因素载荷均有影响,但对神经质维度影响不大。并且,该效应既可能使五维度间相关系数降低,也可能使其相关系数膨胀并出现虚假相关,未来使用该量表应同时纳入正、反向题方法因素。另外,特质乐观可正向预测CBF-PI-B的正、反向题表述效应。

The item wording effect brought by positively or negatively worded items will cause the bias of results. The domestic self-compiled sentence Big Five Personality scale, nevertheless, still lacks the test and control of such effect. Taking the sentence Chinese Big Five Personality Inventory Brief version (CBF-PI-B) as an example, the current research aimed to examine the item wording effect by the correlated trait-correlated method (CTCM) and evaluate the influence of item wording effect on its measurement model. Further, the relationship between dispositional optimism and the positively and negatively worded method factors were explored. The results showed that positively and negatively worded effects were both non-ignorable in CBF-PI-B, which had an effect on the factor loadings of agreeableness, conscientiousness, extraversion and openness, but had little effect on the neuroticism dimension. Moreover, item wording effect could not only reduce the correlation coefficients among the five dimensions, but also make the correlation coefficients expand and appear false correlations, indicating that method factors of both positively and negatively worded items should be taken into consideration in future studies. In addition, dispositional optimism positively predicted the positively and negatively worded effect on CBF-PI-B.
