| Summary: | 碩士 === 國立屏東大學 === 教育心理與輔導學系碩士班 === 103 === The purpose of this study was to use exploratory factor analysis (EFA), confirmatory factor analysis (CFA) to examine the psychometric properties of the Big Five Inventory (BFI；John, Donahue, & Kentle, 1991). In the study, participants included 844 high school students, randomly divided into two samples. Sample 1 was for EFA (421 students; 215 males; 206 females) and sample 2 was for CFA (423 students; 182 males; 241 females). Additionally, a sample of 247 participants were used for reliability analysis and a sample of 266 participants were applied for convergent validity analysis.
In EFA, the results showed that BFI-34 was represented by five factors: Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness to Experience after removing 10 mis-fitting items. In CFA, the models of all versions of BFI (e.g., BFI-44, BFI-29, BFI-21, BFI-15) were not supported in the validation sample, even adding the error correlations based on modification indices. The best fitted solution was the BFI-29 version with five first-order factors. The BFI-29 was modified from the BFI-34.
The score reliability of the BFI-29 was acceptable, with Cronbach’s α ranging from .63 ~ .81 for five factors. The retest reliability was .78~ .87 for five factors. Regarding convergent validity, the BFI-29 and MMI-T were moderately correlated (r= .61 ~ .87). However, the average variance extracted (AVE) for each five factor was below .50. This finding corresponded to two previous studies (i.e., China version BFI-29；Leung, Wong, Chan, & Lam, 2012；German version, BFI-21；Kovaleva, Beierlein, Kemper, & Rammstedt, 2013), but the reasons for low AVE in five factors of personality should be further investigated. Finally, the study provided some implications for school counseling.
