AB Background: The COPD Anxiety Questionnaire (CAF) was developed to assess COPD-specific anxiety. As patients with COPD report high levels of anxiety, there is a need to translate the instrument for widespread use.Aim: 1) Translate CAF into Danish, 2) perform an initial validation in a heterogeneous sample of patients with COPD and 3) compare electronic versus paper responses.Methods: The Danish translation of CAF (CAF-DK) adhered to the World Health Organization guidelines. CAF-DK was distributed with the General Anxiety Disorder-7 (GAD-7; generic anxiety questionnaire), the COPD Assessment Test (CAT; health status questionnaire), socio-demographic and disease-related questions. Electronic responses were collected through a survey link at the Danish Lung Foundation’s webpage and paper responses through the respiratory outpatient unit at Vejle Hospital.Results: A total of 238 patients with COPD completed CAF-DK electronically while 22 completed the paper version. Correlation coefficients between CAF-DK and concurrent measures were comparable to those of the original CAF (CAT, r=0.69; GAD-7, r=0.65). Cronbach’s α of total- and domain-scales ranged from 0.77-0.90. Paper respondents were significantly older and predominantly male, LTOT users, compared to electronic respondents.Conclusion: Psychometric properties of CAF-DK are comparable to CAF and can be used to measure COPD-specific anxiety to Danish-speaking patients either electronically or in paper. However, a larger study with random distribution of electronic versus paper versions in a representative sample of COPD patients across illness grades is needed to confirm equal validity of the formats.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, OA184.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
