MBSRQ-AS
Pearson Correlation					0.481**
p-value (2-tailed)					0.002
N					40

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.
** Correlation is significant at the 0.01 level (2 tailed)
* Correlation is significant at the 0.05 level (2 tailed)
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
