Abstract

Objective: Dyspnea is a distressing symptom of Chronic Obstructive Pulmonary Disease (COPD). The Dyspnea-12 questionnaire, a well-established instrument for assessing different dimensions of dyspnea validated in multiple languages, lacked a Persian version. This study aimed to adapt and validate a Persian version of Dyspnea-12.

Results: The Persian version of Dyspnea-12 demonstrated excellent reliability (Cronbach's alpha = 0.982, Composite Reliability = 0.985). Criterion validity analysis strongly correlated with Dyspnea-12 and CAT scores (ρ = 0.698, p < 0.001). Factor analysis confirmed a single-factor structure consistent with the original version. Inter-item correlations ranged from 0.3 to 0.9. Construct validity indices indicated a satisfactory model fit (CFI = 0.904, SRMR = 0.044), though RMSEA (0.188) suggested areas for improvement. Pulmonary function analysis revealed significant associations between FEV₁ and Dyspnea-12 scores (p = 0.042) and FVC (p = 0.017), linking dyspnea severity with lung function decline.

波斯版呼吸困难-12问卷评估COPD患者呼吸困难的有效性和可靠性。

目的：呼吸困难是慢性阻塞性肺疾病（COPD）的痛苦症状。呼吸困难-12问卷是一种完善的工具，用于评估呼吸困难的不同维度，在多种语言中得到验证，但缺乏波斯语版本。本研究旨在改编和验证波斯语版的呼吸困难-12。结果：波斯语版呼吸困难-12具有良好的信度（Cronbach’s alpha = 0.982，复合信度= 0.985）。标准效度分析与呼吸困难-12和CAT评分密切相关(ρ = 0.698, p
