Test-retest of a Swedish version of the Pulmonary Functional Status & Dyspnea Questionnaire-modified

The number of people suffering from chronic obstructive pulmonary disease (COPD) is increasing. From an occupational therapy perspective, it is important to estimate dyspnea, fatigue and activity performance in daily activities to be able to use the most effective interventions. In Sweden, there are several assessments for evaluating activities in daily living, but none of them are diagnosis specific for this group. The Pulmonary Functional Status & Dyspnea Questionnaire-Modified (PFSDQ-M) is a self-completion assessment, which takes a short time to complete. The aim of this study was to translate the PFSDQ-M into Swedish and test it twice on 30 people to make a test-retest assessment. The aim was also to evaluate the interviewees' experience of filling in the form. Agreement between the assessments was examined by percentage agreement (PA) and unweighted kappa value (k). The test-retest shows the complexity of evaluating the influence of dyspnea and fatigue in performing activities. It was easier to reach agreement in a five-point scale compared to an eleven-point scale. When it comes to screening people with COPD, the PFSDQ-M can be a valuable instrument for detecting individuals who require occupational therapy.
