Despite their importance on diagnostic accuracy, there is a paucity of literature on questionnaire tools to assess clinicians' awareness toward cognitive errors. A validation study was conducted to develop a questionnaire tool to evaluate the Clinician's Awareness Towards Cognitive Errors (CATChES) in clinical decision making.
This questionnaire is divided into two parts. Part A is to evaluate the clinicians' awareness towards cognitive errors in clinical decision making while Part B is to evaluate their perception towards specific cognitive errors. Content validation for both parts was first determined followed by construct validation for Part A. Construct validation for Part B was not determined as the responses were set in a dichotomous format.
For content validation, all items in both Part A and Part B were rated as "excellent" in terms of their relevance in clinical settings. For construct validation using exploratory factor analysis (EFA) for Part A, a two-factor model with total variance extraction of 60% was determined. Two items were deleted. Then, the EFA was repeated showing that all factor loadings are above the cut-off value of >0.5. The Cronbach's alpha for both factors are above 0.6.
The CATChES questionnaire tool is a valid questionnaire tool aimed to evaluate the awareness among clinicians toward cognitive errors in clinical decision making.
尽管问卷工具对诊断准确性很重要，但关于评估临床医生对认知错误认识的文献却很少。开展了一项验证研究，以开发一种问卷工具来评估临床医生在临床决策中对认知错误的认识（CATChES）。
该问卷分为两部分。A部分用于评估临床医生在临床决策中对认知错误的认识，而B部分用于评估他们对特定认知错误的看法。首先确定两部分的内容效度，然后对A部分进行结构效度验证。由于B部分的回答采用二分法格式，因此未确定其结构效度。
在内容效度方面，A部分和B部分的所有项目在临床环境中的相关性方面均被评为“优秀”。对于使用探索性因子分析（EFA）对A部分进行的结构效度验证，确定了一个总方差提取率为60%的双因素模型。删除了两个项目。然后，重复进行探索性因子分析，结果显示所有因子载荷均高于>0.5的临界值。两个因子的克朗巴哈系数均高于0.6。
CATChES问卷工具是一种有效的问卷工具，旨在评估临床医生在临床决策中对认知错误的认识。
