The Defense Style Questionnaire-40 (DSQ-40; Andrews, Singh, & Bond, 1993) uses pairs of items to measure 20 individual defense mechanisms. In a statistical sense, these item pairs represent parcels and are subject to the standards of unidimensionality demanded of parcels in general. Using a 2-facet modeling approach (N = 672), the present study examined the dimensionality of the defense-mechanism parcels in the DSQ-40 and found that the majority of the parcels did not satisfy the criteria for unidimensionality. In addition, the original 3-factor model of defense styles was not tenable with the present data. Overall, the results suggest caution when attempting to assess individual defense mechanisms using the DSQ-40.
防御方式问卷-40（DSQ-40；安德鲁斯、辛格和邦德，1993年）使用成对项目来测量20种个体防御机制。从统计学意义上讲，这些项目对代表了分量表，并且总体上要符合分量表所要求的单维性标准。本研究采用双层面建模方法（N = 672），检验了DSQ-40中防御机制分量表的维度，发现大多数分量表不符合单维性标准。此外，原有的防御方式三因素模型在当前数据中并不成立。总体而言，研究结果表明，在试图使用DSQ-40评估个体防御机制时应谨慎。
