Abstract
The aim of the study is to develop a scale that could assess illness perception and reaction in patients with COPD. The study was conducted in the 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 fifty-four items was prepared as Likert type 5 rating scale. In the validity phase of the study, expert judgments were obtained for content validity then explanatory and confirmatory factor analysis were used. The reliability of the scale in terms of internal consistency was tested with the Cronbach Alpha coefficient. According to the results of the exploratory factor analysis, COPD Perception and Reaction Scale consists of 3 sub-dimensions and 23 items. Factors are named as behavioral reaction, emotional reaction and spiritual reaction. According to confirmatory factor analysis, the goodness-of-fit indices obtained (x2 / df = (676,47 / 227) 2.98 and RMSEA = .056, NFI = .80, CFI = .96, NFI = .91 and AGFI = .85) suggests that the recommended model for the scale is acceptable. The Cronbach’s alpha coefficient was found as .74, and for the sub-dimensions Cronbach’s alpha values were calculated as .87 for “emotional reaction”, .76 for “behavioral reaction” and .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 towards illness in COPD patients in Turkey.
