随着DSM-III-R的出现，广泛性焦虑障碍（GAD）的诊断标准从强调自主觉醒转向了障碍的认知成分，即担忧。宾夕法尼亚州立大学担忧问卷是为了评估担忧的特征而开发的，在一系列主要基于大学生样本的研究中，该问卷已被证明是一种可靠且有效的衡量标准。本研究的目的是评估的心理测量学性质和实用程序的PSWQ在436例焦虑症患者和32名正常对照的临床样本。因素分析表明，PSWQ评估一个一维的结构。此外，PSWQ证明了相当有利的内部一致性使用GAD患者和其他焦虑症组和正常对照组。PSWQ的有效性得到了一项分析的支持，该分析表明，该措施将GAD与其他焦虑症组（包括强迫症组）区分开来。此外，PSWQ和焦虑，抑郁和情绪控制的措施之间的相关性支持的收敛和判别效度的措施。总的来说，研究结果有利于使用PSWQ研究GAD的性质和治疗以及正常和病理性担忧的过程。
With the advent of DSM-III-R, the diagnostic criteria for generalized anxiety disorder (GAD) shifted in emphasis from the autonomic arousal to the cognitive component of the disorder, namely worry. The Penn State Worry Questionnaire was developed to assess the trait of worry and has proven to be a reliable and valid measure in a series of studies largely based on college student samples. The purpose of the present study was to assess the psychometric properties and utility of the PSWQ in a clinical sample of 436 anxiety disorder patients and 32 normal controls. Factor analysis indicated that the PSWQ assesses a unidimensional construct. Furthermore, the PSWQ evidenced quite favorable internal consistency using GAD patients and each of the other anxiety disorder groups and normal controls. The validity of the PSWQ was supported by an analysis indicating that the measure distinguished GADs from each of the other anxiety disorder groups including those with obsessive-compulsive disorder. Moreover, correlations between the PSWQ and measures of anxiety, depression, and emotional control supported the convergent and discriminant validity of the measure. Collectively, the findings speak favorably to the use of the PSWQ in research examining the nature and treatment of GAD and the processes of normal and pathological worry.
