Abstract

Scand J Caring Sci; 2012; 26; 615-623 Danish version of 'The COPD self-efficacy scale': translation and psychometric properties The aim of the study was to translate 'The COPD self-efficacy scale' (CSES) into Danish and to evaluate the psychometric properties of the Danish version (CSES-DK). CSES enables assessment of self-efficacy in individuals with chronic obstructive pulmonary disease (COPD). The scale consists of 34 items, describing situations which may cause dyspnoea in patients with COPD. The CSES was translated into Danish using a standard forward-backward translation procedure. To estimate the reliability, measurements of internal consistency and repeatability were applied. The validity of the Danish version was evaluated by examining the associations between the CSES-DK score and socio-demographic variables (age, gender, education, disease severity and self-rated health). Factor analysis was conducted to compare the internal structure of the Danish version and the American source version. The study included 151 patients with COPD, recruited from three outpatient clinics. Estimates of reliability were in accordance with the original version of CSES (Cronbach's a = 0.97, test-retest r = 0.82, p
