Peripheral arterial disease (PAD) is associated with adverse cardiovascular events and can significantly impair patients' health status. Recently, marked methodological improvements in the measurement of PAD patients' health status have been made. The Peripheral Artery Questionnaire (PAQ) was specifically developed for this purpose. We validated a Dutch version of the PAQ in a large sample of PAD patients.
Cross-sectional study.
The Dutch PAQ was completed by 465 PAD patients (70% men, mean age 65+/-10 years) participating in the Euro Heart Survey Programme. Principal components analysis and reliability analyses were performed. Convergent validity was documented by comparing the PAQ with EQ-5D scales.
Three factors were discerned; Physical Function, Perceived Disability, and Treatment Satisfaction (factor loadings between 0.50 and 0.90). Cronbach's alpha values were excellent (mean alpha=0.94). Shared variance of the PAQ domains with EQ-5D scales ranged from 3 to 50%.
The Dutch PAQ proved to have good measurement qualities; assessment of Physical Function, Perceived Disability, and Treatment Satisfaction facilitates the monitoring of patients' perceived health in clinical research and practice. Measuring disease-specific health status in a reliable way becomes essential in times were a wide array of treatment options are available for PAD patients.
外周动脉疾病（PAD）与不良心血管事件相关，会显著损害患者的健康状况。最近，在测量PAD患者健康状况方面取得了显著的方法学改进。外周动脉问卷（PAQ）就是专门为此目的而开发的。我们在大量PAD患者样本中对荷兰版PAQ进行了验证。
横断面研究。
465名参与欧洲心脏调查项目的PAD患者（70%为男性，平均年龄65±10岁）完成了荷兰版PAQ。进行了主成分分析和可靠性分析。通过将PAQ与EQ-5D量表进行比较来记录收敛效度。
识别出三个因素；身体功能、感知残疾和治疗满意度（因子载荷在0.50至0.90之间）。克朗巴赫α值极佳（平均α = 0.94）。PAQ各领域与EQ-5D量表的共同方差范围为3%至50%。
荷兰版PAQ被证明具有良好的测量质量；对身体功能、感知残疾和治疗满意度的评估有助于在临床研究和实践中监测患者的感知健康状况。在有多种治疗选择可供PAD患者使用的时候，以可靠的方式测量特定疾病的健康状况变得至关重要。
