Background: A reliable, valid questionnaire is essential to assess patient satisfaction with breast reconstruction. %26lt;br%26gt;Methods: A 105-item pilot BRECON questionnaire was previously developed. One hundred eighty-one women with breast reconstruction were mailed the pilot BRECON, BREAST-Q (TM), and EQ-5D questionnaires. Fifty women were re-mailed the BRECON. Based on the responses, the BRECON was refined using statistical means and principal components analysis (PCA). Reliability was assessed using the intraclass correlation coefficient (ICC) and Cronbach%26apos;s alpha. Validity was assessed by comparing subscales of the BRECON to the BREAST-Q (TM) and comparing a summary score of the BRECON-31 to the EQ-5D using the Pearson%26apos;s correlation coefficient (PCC). %26lt;br%26gt;Results: A total of 71% (128/181) of women completed the three questionnaires, and 86% (43/50) of women responded to the re-mailed BRECON. Statistical methods and PCA maintained 31 items covering eight components including self-image, arm concerns, intimacy, satisfaction, recovery, self-consciousness, expectations, and breast appearance. A 4-item nipple subscale and a 10-item abdominal subscale were developed for use where applicable. Measures of reliability and validity were high: Cronbach%26apos;s alpha ranged from 0.67 to 0.91, ICC ranged from 0.55 to 0.85, and PCC ranged from 0.42 to 0.76. %26lt;br%26gt;Conclusions: A reliable, valid 31-item breast reconstruction satisfaction questionnaire was developed.
