Pulmonary rehabilitation (PR) is an effective intervention for people with interstitial lung disease (ILD), as it improvesexercise capacity, quality of life and dyspnoea. Less is, however, known about other important and frequentsymptoms, such as anxiety and depression. This study explored the response of anxiety and depression symptomsto PR in people with ILD.
Participants undertook a 12-week community-based PR programme. Anxiety and depression symptoms wereevaluated before and after PR with the hospital anxiety and depression scale (HADS). The sample was stratified into2 groups according to the HADS score: ≥8 probable anxiety (PA) or depression (PD) and score <8 normal symptoms(NS). Responders were classified using the HADS minimal clinical important difference (≥1.5 points).
46 people with ILD (62±13 years; 63%♀; 75±20 FVC%; 56±18 DLCO%) participated. Number of responders inanxiety symptoms (73% PA; HADS-A pre: 12±3; mean change: 4±2; p<0.001 vs 25% NS; HADS-A pre: 6±2; meanchange: 2±0; p<0.001) was much higher than in depression symptoms (27% PD; HADS-D pre: 11±3; mean change:3±1; p=0.014 vs 13% NS; HADS-D pre: 5±2; mean change: 2±1; p=0.003).
PR seems to improve anxiety symptoms, but it might not be as effective for depression symptoms in people with ILD.Future studies are needed to investigate the role of PR in the psychological health of people with ILD.publishe
