The present report describes the development of the Penn State Worry Questionnaire to measure the trait of worry. The 16-item instrument emerged from factor analysis of a large number of items and was found to possess high internal consistency and good test-retest reliability. The questionnaire correlates predictably with several psychological measures reasonably related to worry, and does not correlate with other measures more remote to the construct. Responses to the questionnaire are not influenced by social desirability. The measure was found to significantly discriminate college samples (a) who met all, some, or none of the DSM-III-R diagnostic criteria for generalized anxiety disorder and (b) who met criteria for GAD vs posttraumatic stress disorder. Among 34 GAD-diagnosed clinical subjects, the worry questionnaire was found not to correlate with other measures of anxiety or depression, indicating that it is tapping an independent construct with severely anxious individuals, and coping desensitization plus cognitive therapy was found to produce significantly greater reductions in the measure than did a nondirective therapy condition.
本报告描述了用于测量担忧特质的宾夕法尼亚州立大学担忧问卷的编制过程。该包含16个条目的工具源自对大量条目进行的因素分析，结果发现其具有较高的内部一致性和良好的重测信度。该问卷与若干与担忧合理相关的心理测量指标呈现出可预测的相关性，而与其他与该构念关联较远的测量指标则无相关性。对问卷的回答不受社会赞许性的影响。研究发现，该测量方法能够显著区分出以下几类大学生样本：(a) 符合、部分符合或不符合《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）广泛性焦虑症所有诊断标准的样本；(b) 符合广泛性焦虑症标准与符合创伤后应激障碍标准的样本。在34名被诊断为广泛性焦虑症的临床受试者中，发现担忧问卷与其他焦虑或抑郁测量指标无相关性，这表明它所测量的是一个独立的构念，且对于严重焦虑个体而言，应对脱敏加认知疗法比非指导性治疗条件能使该测量指标产生更显著的降低。
