The evidence for the division of defenses measured with the Defense Style Questionnaire (DSQ) into immature, neurotic, and mature types appears to be lacking. We hypothesized that defenses can be represented unidimensionally. Classical multidimensional scaling was applied to the maturity ratings of items given by 279 experts. It appeared that the items of the DSQ can be represented unidimensionally. In a second study, two three-factor models of the DSQ were tested with confirmatory factor analysis, using scores of 543 psychiatric outpatients. Both three-factor models were implausible. A third study showed that the overall defensive functioning scores derived from the first study discriminated well between samples of 543 psychiatric outpatients, 69 medical students, and 68 graduate students attending a student counselor. We also found that the overall defensive functioning scores correlated positively with the current Global Assessment of Functioning in the psychiatric sample. We concluded that the DSQ is a useful instrument for measuring overall defensive functioning.
用防御方式问卷（DSQ）将防御分为不成熟型、神经症型和成熟型，这方面的证据似乎并不充分。我们假设防御可以用一维方式来表示。经典多维标度法应用于279位专家给出的项目成熟度评分。结果显示，DSQ的项目可以用一维方式来表示。在第二项研究中，用验证性因素分析对DSQ的两个三因素模型进行了检验，使用了543名精神科门诊患者的得分。这两个三因素模型都不合理。第三项研究表明，从第一项研究得出的总体防御功能得分能够很好地区分543名精神科门诊患者、69名医科学生和68名接受学生咨询服务的研究生样本。我们还发现，在精神科样本中，总体防御功能得分与当前的功能总体评定呈正相关。我们得出结论，DSQ是测量总体防御功能的一种有用工具。
