| N = 72 | CSES rating scorea |
|
|---|---|---|
| R value | P value | |
| 6MWD | 0.37 | <0.01 |
| BASDECa | −0.31 | <0.01 |
| LCADL | −0.33 | <0.01 |
| SGRQ Total Score | −0.53 | <0.00 |
| Smoking pack years | −0.11 | 0.36 |

CSES higher score = greater self efficacy and higher BASDEC = higher depression. LCADL Higher score = worse breathlessness.
