To develop and validate a scale to measure fear of activity in patients with coronary artery disease.
Psychometric study.
Outpatient cardiology clinics.
The scale was applied to patients who had myocardial infarction, coronary artery bypass grafting, or percutaneous coronary intervention within the last 12 months (N=250).
A scale for fear of activity in patients with coronary artery disease (Fact-CAD) was created through semistructured focus group interviews with patients. Face and content validity of Fact-CAD was verified.
Psychometric analysis included model fit, unidimensionality, reliability, local dependency, differential item functioning, and external construct validity. Analyses were performed using the Rasch Analysis Model.
Fact-CAD scale was a reliable (high Person Separation Index of 0.89) and valid (unidimensional, no misfit, local independency supported, no residual correlations) measure of fear of activity. Three items showed differential item functioning according to employment status, marital status, and angina pectoris, which were not assigned as real item bias by experts and remained in the model.
Fact-CAD was supported by Rasch analysis as a psychometrically valid scale to evaluate fear of activity in patients with coronary artery disease.
开发并验证用于测量冠心病患者活动恐惧的量表。
心理测量研究。
门诊心脏病学诊所。
该量表应用于在过去 12 个月内发生心肌梗死、冠状动脉旁路移植术或经皮冠状动脉介入治疗的患者（N=250）。
通过对冠心病患者的半结构化焦点小组访谈创建了活动恐惧量表（Fact-CAD）。验证 Fact-CAD 的表面和内容效度。
心理测量分析包括模型拟合、单维性、信度、局部依赖性、差异项目功能和外部结构效度。使用 Rasch 分析模型进行分析。
Fact-CAD 量表是一种可靠的（高个人分离指数为 0.89）和有效的（单维、无失配、局部独立性得到支持、无残余相关性）活动恐惧测量工具。根据就业状况、婚姻状况和心绞痛，有 3 个项目显示出差异项目功能，但这些项目未被专家视为真实项目偏差，并保留在模型中。
Fact-CAD 通过 Rasch 分析得到支持，是一种心理测量学上有效的量表，可用于评估冠心病患者的活动恐惧。
