Table 2 Responsiveness of the HRQL instruments used in this study

From: Methodology and measurement properties of health-related quality of life instruments: A prospective study of patients undergoing breast reduction surgery

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
  1. 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)
  2. ES1 = Δ / SD at baseline; Difference (Δ) = mean score at 6 month assessment minus mean score at baseline.
  3. * 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.
