以188名中学生为被试，使用大五人格测验简版量表，重复测量实验设计，检验纸笔测验与网络测验等值性。研究发现：（1）责任心分量表网络式得分显著高于纸笔式得分，神经质、外倾性、开放性、宜人性分量表在网络式与纸笔式之间的得分没有显著差异；（2）大五人格测验简版60个项目中，8个项目的网络式得分与纸笔式得分有显著差异；（3）神经质分量信度，网络式与纸笔式相等，外倾性分量表信度纸笔式高于网络式，开放性、宜人性、责任心三个分量以及总量表信度，网络式均高于纸笔式；（4）网络式大五人格测验简版、纸笔式大五人格测验简版不具有与大五人格相同的理论结构，且自身的因素结构存在差异。因此，大五人格测验简版的网络式与纸笔式数据不能简单合并计算并分析。

This study focuses on equivalence of paper-pencil test and on-line test by a repeated measurement design with data collected from 188 high school students, using the Big Five Inventory (Brief Version) as an example. Results show that (1): score of the conscientiousness subscale of on-line format is significantly higher than paper-pencil one. No significant difference is found between neurotic, openness, extrovert and agreeableness subscale of on-line and paper-pencil formats; (2) among all the 60 items, only 8 items score significantly different between paper-pencil format and on-line one; (3)no significant difference of reliability of neurotic subscale between paper-pencil format and on-line one is found; paper-pencil extrovert subscale scores significantly higher. On-line openness, agreeableness and conscientiousness subscale score significantly higher. (4) both paper-pencil and on-line formats of the Big Five Inventory contain structure different from the Big Five Theory, and they two differs in terms of factorial structure. Therefore, date collected by paper-pencil and on-line Big Five Inventory ( Brief Version) can‘t be simply merged and analyzed.
