Abstract

One hundred and thirty-eight chronic obstructive pulmonary disease (COPD) patients completed the Breathing Problems Questionnaire (BPQ) before and after a comprehensive programme of rehabilitation. Examination of the changes on individual items showed improvement on 22 items, of which four items were significant at p < 0.05 and deterioration on nine items, of which two were significant at p < 0.01. All deteriorating items were consistent with lifestyle adaptations encouraged as part of the rehabilitation programme. We examined the psychometric properties of a reduced ten item version of the BPQ limited to the items most sensitive to change. We recommend the purpose-specific, disease-specific COPD scale for measuring change in pulmonary rehabilitation assessment in contrast to the longer 33 item questionnaire, which, however, may be more useful for cross-sectional assessment.

Adaptação cultural e reprodutibilidade do questionário para problemas respiratórios em pacientes portadores de DPOC no Brasil

“…The correlation between the long and short versions in terms of the total score was 0.91 (p < 0.001), (7,8) similar to the correlation of reproducibility found in our study of the long version, which had an ICC of 0.94. We observed that the long version questions that had the lowest kappa values were the same as those that were eliminated from the short version, which indicates that those questions might not have shown good concordance in the studies by the questionnaire developers.…”

“…We observed that the long version questions that had the lowest kappa values were the same as those that were eliminated from the short version, which indicates that those questions might not have shown good concordance in the studies by the questionnaire developers. (7,8) At the end of the process, we observed that the questionnaire required few cultural adaptations and showed excellent reproducibility. Most qualityof-life questionnaires for patients with COPD have originally been written in a language other than Portuguese, therefore requiring adaptation before they can be used in our country.…”

“…Most domains, the two subscales, and the total score showed excellent reproducibility; only the domains "social interactions" and "effects of catching colds" had a moderate to good ICC; none of the domains had ICCs that could be considered weak, a finding that is similar to those of the studies in which the long and short versions of the BPQ were developed. (7,8) Usually, ICCs equal to or greater than 0.75 are considered to show good reproducibility.…”

“…(8) However, in order to be used in Brazil, the BPQ had to be translated and culturally adapted, and its reproducibility had to be evaluated. The translation of the BPQ into Brazilian Portuguese and its adaptation to the Brazilian culture would allow its use in Brazil and provide yet another efficient tool for the evaluation and management of patients with COPD with a view to pulmonary rehabilitation programs and therapeutic strategies.…”

Five-year follow-up of a one-year self-management program for patients with COPD

“…Coping with breathlessness generally was assessed using Breathing Problems Questionnaire (BPQ) short version23 (the Norwegian version) 24. This version consists of ten items with a possible score between zero and 30 where zero indicates no problem.…”
