This study examined the psychometric properties of the 19-item Thought-Action Fusion (TAF) Scale, a measure of maladaptive cognitive intrusions, in a large clinical sample (N = 700). An exploratory factor analysis (n = 300) yielded two interpretable factors: TAF Moral (TAF-M) and TAF Likelihood (TAF-L). A confirmatory bifactor analysis was conducted on the second portion of the sample (n = 400) to account for possible sources of item covariance using a general TAF factor (subsuming TAF-M) alongside the TAF-L domain-specific factor. The bifactor model provided an acceptable fit to the sample data. Results indicated that global TAF was more strongly associated with a measure of obsessive-compulsiveness than measures of general worry and depression, and the TAF-L dimension was more strongly related to obsessive-compulsiveness than depression. Overall, results support the bifactor structure of the TAF in a clinical sample and its close relationship to its neighboring obsessive-compulsiveness construct.
本研究在一个大的临床样本（N=700）中检验了 19 项思维-行为融合（TAF）量表的心理计量学特性，该量表用于测量适应不良的认知闯入。一项探索性因素分析（n=300）得出了两个可解释的因素：TAF 道德（TAF-M）和 TAF 可能性（TAF-L）。在样本的第二部分（n=400）上进行了验证性双因素分析，使用一般 TAF 因素（包含 TAF-M）和 TAF-L 特定领域因素来解释可能的项目协方差来源。双因素模型为样本数据提供了可接受的拟合。结果表明，全球 TAF 与强迫症的衡量标准比一般忧虑和抑郁的衡量标准更密切相关，而 TAF-L 维度与强迫症的关系比抑郁更为密切。总体而言，结果支持 TAF 在临床样本中的双因素结构及其与相邻强迫症结构的密切关系。
