The aim of this study was to develop the Dyspnoea-12-Arabic (D-12-A) questionnaire and test its reliability and validity for the assessment of breathlessness in Arabic speaking patients with chronic obstructive pulmonary disease (COPD) in Jordan.
Breathlessness is a complex multidimensional symptom which incorporates physiology and psychology.
The D-12-A, Hospital Anxiety and Depression Scale (HADS), and Quality of Life Index pulmonary version (QLI-P) were completed by 67 Jordanian patients with COPD. Cronbach alpha was used to assess internal consistency, and Pearson product-moment correlation calculated for construct validity.
The D-12-A and its sub-components ('physical' and 'affective') demonstrated excellent internal reliability (Cronbach alpha range from 0.88 to 0.91). D-12-A scores correlated significantly with other relevant outcome measures and demonstrated good construct validity.
The D-12-A should provide clinicians and researchers with a useful tool for the assessment of breathlessness in Arabic speaking patients with COPD.
本研究旨在开发阿拉伯语呼吸困难问卷（D-12-A），并在约旦的阿拉伯语 COPD 患者中评估其用于呼吸困难评估的可靠性和有效性。
呼吸困难是一种复杂的多维症状，包含生理和心理两个方面。
67 名约旦 COPD 患者完成了 D-12-A、医院焦虑和抑郁量表（HADS）和肺质量生活指数（QLI-P）。采用克朗巴赫 α 评估内部一致性，皮尔逊积矩相关计算结构效度。
D-12-A 及其分量表（“生理”和“情感”）表现出极好的内部一致性（克朗巴赫 α 范围为 0.88 至 0.91）。D-12-A 评分与其他相关结局测量显著相关，表现出良好的结构效度。
D-12-A 应为临床医生和研究人员提供一种有用的工具，用于评估阿拉伯语 COPD 患者的呼吸困难。
