大五人格问卷在是否投喂流浪猫狗群体中的测量等值性研究

A Study on the Measurement Invariance of the Big Five Personality Inventory across Feeding and Non-Feeding Groups of Stray Cats and Dogs

摘要: 本研究旨在探讨大五人格问卷在投喂流浪猫狗群体和不投喂流浪猫狗群体中的测量等值性，检验两群体在人格特质上的差异。使用简版的大五人格特质问卷(MINI International Personality Item Pool, Mini-IPIP)，以线上线下的方式收集457份问卷，验证性因子分析和探索性结构方程模型结果显示Mini-IPIP的五个维度均拟合良好(CFI: 0.989~0.998, RMSEA: 0.011~0.030, SRMR: 0.013~0.042)。多组探索性结构方程模型显示，简版大五人格特质问卷在投喂组和不投喂组的组间形态等值、弱等值、强等值和严格等值模型均可被接受(ΔCFI < 0.01, ΔRMSEA < 0.01)；Mini-IPIP的因子结构良好地拟合数据，且在投喂组和不投喂组之间达到严格等值。在确认了两群体具有测量等值性后，采用独立样本t检验和因子平均数差异比较来对两群体进行组间比较，结果显示，两群体在宜人性和神经质两维度上存在显著差异；但投喂组和不投喂组在开放性维度(t = 1.683, p = 0.883, d = 0.163)没有显著差异。综上所述，Mini-IPIP在投喂者和不投喂者之间严格等值，且投喂者比不投喂者的宜人性、神经质得分都会更高。

Abstract: This study aims to explore the measurement equivalence of the Big Five Personality Questionnaire between groups that feed stray cats and dogs and those that do not, examining the differences in personality traits between the two groups. Using the short version of the Big Five Personality Traits Questionnaire (MINI International Personality Item Pool, Mini-IPIP), a total of 457 questionnaires were collected through online and offline methods. Confirmatory factor analysis and exploratory structural equation modeling results indicate that the five dimensions of the Mini-IPIP fit well (CFI: 0.989~0.998, RMSEA: 0.011~0.030, SRMR: 0.013~0.042). Multi-group exploratory structural equation modeling shows that the forms of measurement invariance, weak invariance, strong invariance, and strict invariance of the short version of the Big Five Personality Traits Questionnaire between the feeding group and the non-feeding group are all acceptable (ΔCFI < 0.01, ΔRMSEA < 0.01); the factor structure of the Mini-IPIP fits the data well and achieves strict invariance between the feeding and non-feeding groups. After confirming the measurement equivalence between the two groups, independent samples t-tests and factor mean difference comparisons were conducted for inter-group comparisons. The results indicate significant differences in the dimensions of agreeableness, neuroticism, conscientiousness, and extraversion; however, there is no significant difference in the openness dimension between the feeding group and the non-feeding group (t = 1.683, p = 0.883, d = 0.163). In summary, the Mini-IPIP demonstrates strict equivalence between feeders and non-feeders, with feeders scoring higher in agreeableness and neuroticism than non-feeders.
