The aim of the study is to develop a scale that could assess illness perception and reaction in patients with chronic obstructive pulmonary disease (COPD).
The study was conducted in patients who were admitted in the pulmonary disease departments of a public and a private hospital. The study included 271 COPD patients. The COPD Perception and Reaction Scale, consisting of 54 items, was prepared as a Likert-type 5-point rating scale. In the validity phase of the study, expert judgments were obtained for content validity, and explanatory and confirmatory factor analyses (EFA and CFA) were then performed. The reliability of the scale in terms of internal consistency was tested with the Cronbach's alpha coefficient.
According to the results of the EFA, the COPD Perception and Reaction Scale consists of 3 subdimensions and 23 items. Factors are termed behavioral reaction, emotional reaction, and spiritual reaction. According to the CFA, the goodness-of-fit indices obtained (χ2/df = (676.47/227) 2.98 and RMSEA = 0.056, NFI = 0.80, CFI = 0.96, NFI = 0.91, and AGFI = 0.85) suggest that the recommended model for the scale is acceptable. The Cronbach's alpha coefficient was 0.74; Cronbach's alpha values for the subdimensions were calculated as 0.87 for "emotional reaction," 0.76 for "behavioral reaction," and 0.79 for "spiritual reaction."
The 23-item form of the COPD Illness Perception and Reaction Scale was demonstrated to be a valid and reliable scale for determining the perception and the reaction toward illness in COPD patients in Turkey.
本研究旨在开发一种能够评估慢性阻塞性肺疾病（COPD）患者疾病认知和反应的量表。
本研究在一家公立医院和一家私立医院的肺病科收治的患者中进行。研究纳入了271例COPD患者。COPD认知与反应量表由54个项目组成，采用李克特5级评分量表。在研究的效度阶段，通过专家判断获得内容效度，然后进行解释性和验证性因素分析（EFA和CFA）。量表的内部一致性信度用克朗巴哈α系数进行检验。
根据EFA结果，COPD认知与反应量表由3个维度和23个项目组成。这些因素分别称为行为反应、情绪反应和精神反应。根据CFA，所获得的拟合优度指标（χ2/df =（676.47/227）2.98，RMSEA = 0.056，NFI = 0.80，CFI = 0.96，NNFI = 0.91，AGFI = 0.85）表明该量表推荐模型是可接受的。克朗巴哈α系数为0.74；各维度的克朗巴哈α值计算如下：“情绪反应”为0.87，“行为反应”为0.76，“精神反应”为0.79。
COPD疾病认知与反应量表的23项版本被证明是一种有效且可靠的量表，用于确定土耳其COPD患者对疾病的认知和反应。
