Positive beliefs about worry are an important factor that has been shown to be associated with the reduction of worry severity with cognitive behavioural therapy. The present study evaluated the psychometric properties of a measure of positive beliefs about worry, the Why Worry Questionnaire II (WW-II; Hebert et al., 2014, 0.1016/j.paid.2013.08.009) with a clinical sample. The present study also compared mean scores on the WW-II in the present clinical sample with scores found in non-clinical samples. Finally, the study compared mean scores on the WW-II between groups with primary diagnoses of generalized anxiety disorder (GAD), major depressive disorder (MDD) and anxiety disorder not otherwise specified (NOS). The confirmatory factor analysis found the five-factor model an adequate to good fit to the data, and the WW-II demonstrated excellent internal consistency within this clinical sample. Additionally, scores on the WW-II in the present sample were significantly higher than scores found by in their non-clinical sample. Finally, no significant mean differences were found between primary diagnoses of GAD, anxiety disorder NOS or MDD. Important theoretical and clinical implications and suggestions for future research are discussed.

关于担忧的积极信念：对焦虑和情绪障碍患者的Why Worry-II问卷的评估：对理论和治疗的影响

对担忧的积极信念是一个重要因素，已被证明与认知行为疗法降低担忧严重程度有关。本研究通过临床样本评估了衡量积极信念的心理测量特性，即为什么担心问卷 II（WW-II；Hebert 等人，2014，0.1016/j.paid.2013.08.009）。本研究还将当前临床样本中二战的平均分数与非临床样本中的分数进行了比较。最后，该研究比较了主要诊断为广泛性焦虑症 (GAD)、重度抑郁症 (MDD) 和未特别说明的焦虑症 (NOS) 的组之间二战时的平均得分。验证性因素分析发现五因素模型与数据的拟合度足够好，WW-II 在这个临床样本中表现出极好的内部一致性。此外，本样本中二战的得分明显高于非临床样本中的得分。最后，在 GAD、焦虑症 NOS 或 MDD 的主要诊断之间没有发现显着的平均差异。讨论了重要的理论和临床意义以及对未来研究的建议。
