Responsiveness of the HRQL instruments used in this study
| Measure | Difference | SD at Baseline (1-day pre-op) | SD | ES1 | SRM |
|---|---|---|---|---|---|
| HUI2 (n = 41) | 0.06 | 0.14 | 0.14 | 0.45 | 0.46 |
| HUI3 (n = 41) | 0.12 | 0.19 | 0.17 | 0.63 | 0.67 |
| SF-36 (Physical) (n = 37) | 10.16 | 8.43 | 7.45 | 1.21 | 1.36 |
| SF-36 (Mental) (n = 37) | 7.46 | 11.75 | 12.63 | 0.63 | 0.59 |
| MBSRQ-AS (n = 40) | 0.86 | 0.65 | 0.70 | 1.32 | 1.23 |
| BSS Score (n = 41) | 45.05 | 13.15 | 13.74 | 3.43 | 3.28 |
HUI2 = Health Utilities Index Mark 2; HUI3 = Health Utilities Index Mark 3; SF-36 = Short-Form 36; MBSRQ-AS = Multidimensional Body Self Relations Questionnaire Appearance Assessment; BSS Score = Breast Symptom Summary Score; SD= Standard Deviation; ES1 = Effect Size (based on Cohen, 1988); SRM = Standardized Response Mean; SRM = Δ/SD(Δ)
ES1 = Δ / SD at baseline; Difference (Δ) = mean score at 6 month assessment minus mean score at baseline.
* n's reflect the number of patients who have completed the measure at both time-points (baseline and six months) and hence the difference in numbers from Table 1.
