Abstract

Purpose: The London Chest Activity of Daily Living Scale (LCADL) is a simple, useful, and comprehensive measure of dyspnea perception in activities of daily living. This study was conducted to determine the validity and reliability of the Turkish version of the LCADL.

 

Methods: A total of 64 patients with obstructive lung disease (24 COPD, 20 asthma, and 20 bronchiectasis) were included. The Turkish LCADL was evaluated for inter-observer reliability, testretest reliability, and criterion validity. Two different observers applied the scale with an interval of 10 minutes to assess inter-observer reliability. The second observer applied the scale twice at an interval of 10-15 days to assess test-retest reliability. Criterion validity was assessed using the 6- minute walk test (6MWT), Nottingham Health Profile (NHP), and Saint George Respiratory Questionnaire (SGRQ).

 

Results: The inter-observer validity of the scale was very high (rs=0.985, p<0.05). The Cronbach's alpha coefficient for total score was 0.976 and intraclass correlation coefficient was 0.953. These results indicate that the Turkish LCADL has high reliability. Correlation between LCADL and 6MWT was moderate 0.503 (p=0.002). LCADL total score was weakly correlated with NHP total score (r=0.370, p=0.04) and SGRQ total score (r=0.367, p=0.004).

 

Conclusion: The Turkish version of the LCADL scale is reliable and valid in obstructive lung disease. The LCADL scale will be beneficial in existing pulmonary rehabilitation programs aiming to improve functional status. We believe using the Turkish LCADL scale as an outcome measure in pulmonary rehabilitation programs will serve as an indicator of rehabilitation efficacy for individual patients.
