ABSTRACT Violations of linearity, symmetry, and equidistance of scale points in semantic differential scales may be due to respondents failing to figure out antonyms, to a positivity bias, or to respondents curtailing their reading the options. Multiple correspondence analysis on data provided by a randomized between-subjects experiment (split-ballot), using a web survey of 537 German residents, shows that bipolar semantic differential scales allow for linear measurement and conceal no positivity bias, and that using not suitable adjective pairs in semantic differential scales destroys symmetry.

用于测量自我形象和他人形象的语义微分尺度中的线性、对称性和等距

摘要 语义微分尺度中尺度点的线性、对称性和等距的违反可能是由于受访者未能找出反义词、积极性偏见或受访者减少阅读选项。使用对 537 名德国居民的网络调查，对随机主体间实验（分裂投票）提供的数据进行多重对应分析，结果表明双极语义差异量表允许线性测量且不隐藏任何积极性偏见，并且使用不合适的形容词语义差异尺度中的对破坏了对称性。
