BACKGROUND
The Pulmonary Embolism Quality of Life (PEmb-QoL) questionnaire is the first disease-specific scale for assessing the quality of life in patients with a history of pulmonary embolism (PE).
OBJECTIVES
To assess the cross-cultural validity and reliability of the disease-specific PEmb-QoL questionnaire.
METHODS
The Persian version was prepared through the forward and backward translation of the English questionnaire. Six months after the diagnosis of acute PE, consecutive Persian-speaking patients were asked to complete the PEmb-QoL, the generic 36-item Short Form (SF-36) questionnaires and undertake a 6-minute walk test (6MWT). Acceptability was assessed via item missing rate, reproducibility by the test-retest method, and internal consistency reliability by Cronbach's α and McDonald's ω coefficients. Convergence validity was assessed using the Spearman rank correlation between scores of PEmb-QoL, SF-36, and 6MWT. The questionnaire structure was evaluated through exploratory factor analysis.
RESULTS
Ninety-six patients with a confirmed diagnosis of PE completed the questionnaires. The Persian version of PEmb-QoL had good internal consistency (α = 0.95, 3-factor ω = 0.96), inter-item correlation (0.3-0.62), item-total correlation (0.38-0.71), reproducibility (test-retest ICC with 25 participants = 0.92-0.99), and good discriminant validity. Convergence validity was confirmed by the moderate-to-high correlations between PEmb-QoL and SF-36 scores, and a good correlation between the "limitation in daily activities" dimension of the PEmb-QoL questionnaire and 6MWT results. Exploratory factor analysis suggested a 3-component structure with functional (items 1h, 4b-5d, 6, 8, 9i, and 9j), symptoms (1b-h, 7, and 8), and emotional (5a, 6, and 9a-h) components.
CONCLUSION
The Persian version of the PEmb-QoL questionnaire is valid and reliable for measuring the disease-specific quality of life in patients with PE.
背景
肺栓塞生活质量（PEmb-QoL）问卷是首个用于评估有肺栓塞（PE）病史患者生活质量的疾病特异性量表。
目的
评估疾病特异性PEmb-QoL问卷的跨文化效度和信度。
方法
通过对英文问卷进行正向和反向翻译来编制波斯语版本。在急性PE诊断6个月后，连续招募说波斯语的患者，要求他们完成PEmb-QoL、通用的36项简短形式（SF-36）问卷，并进行6分钟步行试验（6MWT）。通过项目缺失率评估可接受性，通过重测法评估可重复性，通过Cronbach's α系数和McDonald's ω系数评估内部一致性信度。使用PEmb-QoL、SF-36和6MWT得分之间的Spearman等级相关性评估收敛效度。通过探索性因素分析评估问卷结构。
结果
96例确诊为PE的患者完成了问卷。PEmb-QoL的波斯语版本具有良好的内部一致性（α = 0.95，三因素ω = 0.96）、项目间相关性（0.3 - 0.62）、项目与总分相关性（0.38 - 0.71）、可重复性（25名参与者的重测组内相关系数 = 0.92 - 0.99）以及良好的判别效度。PEmb-QoL与SF-36得分之间的中等到高度相关性，以及PEmb-QoL问卷的“日常活动受限”维度与6MWT结果之间的良好相关性证实了收敛效度。探索性因素分析表明存在一个由功能（项目1h、4b - 5d、6、8、9i和9j）、症状（1b - h、7和8）和情感（5a、6和9a - h）组成部分的三成分结构。
结论
PEmb-QoL问卷的波斯语版本对于测量PE患者的疾病特异性生活质量是有效且可靠的。
