Responsiveness of the CROQ (before to three months after revascularisation)
| CROQ scale | Mean (SD) score | Effect size† | ||
| Before | At 3 months | Change* | ||
| CROQ-CABG (n = 198)‡ | ||||
| Symptoms | 48.98 (24.2) | 88.29 (13.9) | 39.31 (25.3) | 2.83 |
| Physical functioning | 50.48 (26.9) | 82.46 (21.8) | 31.98 (29.4) | 1.47 |
| Psychosocial functioning | 49.59 (24.3) | 79.65 (19.7) | 30.05 (23.1) | 1.53 |
| Cognitive functioning | 62.57 (29.2) | 77.94 (22.8) | 15.36 (25.7) | 0.67 |
| CROQ-PTCA (n = 107)‡ | ||||
| Symptoms | 51.98 (23.4) | 75.07 (21.9) | 23.10 (25.2) | 0.99 |
| Physical functioning | 53.39 (27.2) | 71.42 (26.0) | 18.03 (28.3) | 0.66 |
| Psychosocial functioning | 54.32 (25.1) | 71.06 (24.3) | 16.74 (21.5) | 0.67 |
| Cognitive functioning | 68.46 (29.5) | 75.45 (25.7) | 6.99 (23.5) | 0.24 |
*All change scores are significant (p<0.05).
†Calculated as mean change between pre- and three months post-revascularisation scores divided by the standard deviation of scores before revascularisation.
‡Subsample of patients who completed the CROQ both before and after coronary revascularisation.
Note: It is not appropriate to compare CROQ scores for CABG and PTCA groups in this table, as this dataset has not been adjusted in terms of case mix severity, etc.
