Validation of the breast evaluation questionnaire for breast hypertrophy and breast reduction

<p><b>Background:</b> There is a lack of published, validated questionnaires for evaluating psychosocial morbidity in patients with breast hypertrophy undergoing breast reduction surgery.</p> <p><b>Aim:</b> To validate the breast evaluation questionnaire (BEQ), originally developed for the assessment of breast augmentation patients, for the assessment of psychosocial morbidity in patients with breast hypertrophy undergoing breast reduction surgery.</p> <p><b>Study design:</b> Validation study</p> <p><b>Subjects:</b> Women with macromastia</p> <p><b>Methods:</b> The validation of the BEQ, adapted to breast reduction, was performed in several steps. Content validity, reliability, construct validity and responsiveness were assessed.</p> <p><b>Results:</b> The original version was adjusted according to the results for content validity and resulted in item reduction and a modified BEQ (mBEQ) that was then assessed for reliability, construct validity and responsiveness. Internal and external validation was performed for the modified BEQ. Convergent validity was tested against Breast-Q (reduction) and discriminate validity was tested against the SF-36. Known-groups validation revealed significant differences between the normal population and patients undergoing breast reduction surgery. The BEQ showed good reliability by test–re-test analysis and high responsiveness.</p> <p><b>Conclusion:</b> The modified BEQ may be reliable, valid and responsive instrument for assessing women who undergo breast reduction.</p>
