This study aims to investigate the validity and reliability of the Meta-Worry Questionnaire in the Turkish version as a contribution to clinical practice.
The research sample consisted of two groups. Cases were people who have General Anxiety Disorder (n=165) and controls were age and sex-matched healthy volunteers (n=158). To evaluate the psychometric properties of the scale, Meta-Worry Questionnaire, Metacognition Questionnaire-30, Beck Depression Inventory, Beck Anxiety Inventory, Penn State Worry Questionnaire and Generalized Anxiety Disorder-7 Questionnaire were used.
In this study, Cronbach's alpha coefficient values of frequency and belief components were found 0.92 and 0.94, respectively. At the same time, excluding each item, Cronbach's alpha coefficient values of these two components also remained above 0.90, regardless of which item was chosen. While the frequency component accounted for 69.07% of the total variance, the belief component accounted for 72.95%. The area under the ROC curve is 0.948 for the frequency component and 0.944 for the belief component. The construct validity of the scale was tested with Exploratory and Confirmatory Factor Analysis and the one-dimensional structure of the scale was shown. To evaluate the psychometric properties of the scale, other scales which are related to metacognition were used.
All items in the tool displayed a high correlation with the overall questionnaire. High total variance of the scale indicates its high validity. These results suggest high reliability of the tool as well as consistency of every item it includes.
本研究旨在调查土耳其语版元担忧问卷的有效性和可靠性，以对临床实践做出贡献。
研究样本由两组组成。病例组为患有广泛性焦虑症的人（n = 165），对照组为年龄和性别匹配的健康志愿者（n = 158）。为评估该量表的心理测量特性，使用了元担忧问卷、元认知问卷 - 30、贝克抑郁量表、贝克焦虑量表、宾夕法尼亚州立大学担忧问卷和广泛性焦虑症 - 7问卷。
在本研究中，频率和信念分量表的克朗巴赫α系数值分别为0.92和0.94。同时，排除每个项目后，这两个分量表的克朗巴赫α系数值也均保持在0.90以上，无论选择哪个项目。频率分量表占总方差的69.07%，信念分量表占72.95%。频率分量表的ROC曲线下面积为0.948，信念分量表为0.944。通过探索性和验证性因素分析对该量表的结构效度进行了测试，并显示了该量表的一维结构。为评估该量表的心理测量特性，使用了其他与元认知相关的量表。
该工具中的所有项目与总体问卷均显示出高度相关性。量表的高总方差表明其具有较高的有效性。这些结果表明该工具具有较高的可靠性以及其所包含的每个项目的一致性。
