The present study assesses the psychometric properties and factor structure of the Greek version of the Cardiac Anxiety Questionnaire (CAQ). The questionnaire was administered to 598 healthy individuals from 15 different regions of Greece with a measure of socioeconomic characteristics and the Symptom Checklist-90-Revised (SCL-90-R). The sample was split into two random halves, and exploratory factor analysis indicated a three-factor solution. This solution was tested using a confirmatory factor analysis on the second half of the sample. In terms of latent dimensions, the Greek version retains the three-factor structure as proposed by the initial authors. However, adequate fit was achieved only after omitting eight items. The shorter (10-item) version was submitted to further analysis. The shorter version provided satisfactory internal reliability and evidence indicating the validity of the scale with respect to SCL-90-R subscales. The stability of the questionnaire was verified by a high test-retest reliability over a 3-mo. period (r = .86). Sex and age differences were assessed. The 10-item version appears to be a practical, brief tool for clinical use.
本研究评估了希腊语版心脏焦虑问卷（CAQ）的心理测量特性和因子结构。该问卷被施用于来自希腊15个不同地区的598名健康个体，同时测量了社会经济特征和症状自评量表-90修订版（SCL-90-R）。样本被随机分成两半，探索性因子分析表明存在一个三因子解决方案。使用验证性因子分析对样本的后半部分对该解决方案进行了检验。在潜在维度方面，希腊语版保留了最初作者提出的三因子结构。然而，仅在删除8个项目后才获得了足够的拟合度。较短的（10项）版本被进行进一步分析。较短版本提供了令人满意的内部信度，并有证据表明该量表相对于SCL-90-R分量表的有效性。通过3个月期间的高重测信度（r = 0.86）验证了问卷的稳定性。评估了性别和年龄差异。10项版本似乎是一种适用于临床使用的实用、简短工具。
