研究人员描述了两种类型的焦虑者，正常的和病理性的，他们的担忧体验的频率、强度和可控性都不同。虽然正常担忧和病理性担忧通常被视为独立的、虽然相关的现象，但还没有研究针对所有担忧都存在于一个单一维度的替代假设来检验其独立性。在这项研究中，对1,588名大学生的担忧评分被提交给旨在评估潜在结构的征税程序。结果为担忧的维度提供了证据。这些发现表明，以焦虑为主要特征的广泛性焦虑症(GAD)也可能在数量上而不是质量上与正常功能不同。作者认为，对正常和病态极端的关注限制了对担忧现象的研究，并且对担忧的维度概念化可能会显著提高对担忧和广泛性焦虑的理解。
Researchers have described 2 types of worriers, normal and pathological, who differ in the frequency, intensity, and controllability of their worry experiences. Although normal and pathological worry are generally treated as separate though related phenomena, no study has tested for separateness against the alternative hypothesis that all worry exists along a single dimension. In the present study, worry ratings of 1,588 college students were submitted to taxometric procedures designed to evaluate latent structure. Results provided evidence for the dimensionality of worry. These findings suggest that generalized anxiety disorder (GAD), whose central feature is worry, may also be quantitatively rather than qualitatively different from normal functioning. The authors argue that a focus on normal and pathological extremes has constrained the study of worry phenomena and that dimensional conceptualization of worry may significantly enhance understanding of both worry and GAD.
