Introduction: Assessing the capacity for activities of daily living in chronic obstructive pul-monary disease (COPD) patients allows us to determine the limitations imposed by the disease. Prior to this study, the version of the London Chest Activities of Daily Living (LCADL) com-monly used in Portugal was the Brazilian adaptation. Objective: To translate, adapt, and validate the LCADL for the European Portuguese popula-tion and culture. Methodology: Translation and cultural adaptation of the LCADL was performed, followed by a multicentric cross-sectional study for validation. A rehabilitation nurse administered the LCADL-PT and 50% of participants were invited to repeat it two weeks later for reliability. The results of the LDCAL-PT were compared with those of the one-minute sit-to-stand test and the St. George Respiratory Questionnaire for concurrent validity purposes. Results: 107 participants diagnosed with COPD were enrolled; 80 (74.8%) were male, and the mean age was 67.8±7.9 years. A statistically significant negative correlation was found between the one-minute sit-to-stand and the LCADL-PT total score (r=-0.281, p=0.004), and a signifi-cant correlation was found with each of the SGRQ domains, as well as with the total score (symptoms: r=0.230, p=0.017; activity: r=0.428, p<0.001; impact: r=0.341, p<0.001; total: r=0.416, p<0.001). The internal consistency obtained was 0.901, and the intraclass correlation coefficient was 0.898. Conclusion: The European Portuguese version of the LCADL has good psychometric properties and can be considered equivalent to the original English version, in terms of psychometric properties. These results support the use of this instrument both in clinical and research settings to evaluate the impact of COPD on ADL.
