Development of a breast reconstruction satisfaction questionnaire (BRECON): Dimensionality and clinical importance of breast symptoms, donor site issues, patient expectations, and relationships

Abstract

To develop a valid, reliable and responsive, self-administered questionnaire to assess women's satisfaction with breast reconstruction. Item generation: Three sources for item inventory were utilized: focus groups, expert panel, and literature review.Item reduction: Item impact scores were derived from patients and experts each ranking the importance and frequency of each item. Correlation between patient and expert scores was calculated. The highest impact questions were maintained. Four focus groups comprising 20 women generated 515 items, 10 experts developed 171 items, and literature review produced 227 items. These 913 potential items were reduced to 183 by combining redundancy. The 183 items underwent formal reduction by assessing importance and frequency of each item. Thirty-two of 40 reconstructed women and 19 of 19 experts responded to the mail-out. Seventy-seven items of the women's top 100 also made the experts' top 100 list. Intraclass correlation between patients and experts was 0.71 [0.62 0.77], indicating "good" but not "excellent" agreement, reinforcing the importance of patient involvement in questionnaire development. Women rated abdominal donor site issues higher than experts, and experts rated breast softness and symmetry higher than women. A 100-item pilot questionnaire for breast reconstruction satisfaction was developed for psychometric testing.
