Validation of the electronic version of the BREAST-Q in the army of women study

Women undergoing surgery for primary breast cancer can choose between breast conserving therapy and mastectomy (with or without breast reconstruction). Patients often turn to outcomes data to help guide the decision-making process. The BREAST-Q is a validated breast surgery-specific patient-reported outcome measure that evaluates satisfaction, quality of life, and patient experience. It was originally developed for paper-and-pencil administration. However, the BREAST-Q has increasingly been administered electronically. Therefore, the aim of this study was to evaluate the psychometric properties of an electronic version of the BREAST-Q in a large online survey. Women with a history of breast cancer surgery recruited from the Love/AVON Army of Women program completed an electronic version of the BREAST-Q in addition to the Impact of Cancer Survey and PTSD Checklist. Traditional psychometric analyses were performed on the collected data. BREAST-Q data were collected from 6748 women (3497 Breast Conserving Therapy module, 1295 Mastectomy module, 1956 Breast Reconstruction module). Acceptability was supported by a high response rate (82%), low frequency of missing data (\u3c5%), and maximum endorsement frequencies (\u3c80%) in all but 17 items. Scale reliability was supported by high Cronbach\u27s α coefficients (≥0.78) and item-total correlations (range of means, 0.65-0.91). Validity was supported by interscale correlations, convergent and divergent hypotheses as well as clinical hypotheses. The electronically administered BREAST-Q yields highly reliable, clinically meaningful data for use in clinical outcomes research. The BREAST-Q can be used in the clinical setting, whether administered electronically or using paper-and-pencil, at the choice of the patient and surgeon

Development and Validation of the BREAST-Q Breast-Conserving Therapy Module.

BACKGROUND: In breast cancer surgery, patient-reported outcome measures are needed to measure outcomes best reported by patients (e.g., psychosocial well-being). This study aimed to develop and validate a new BREAST-Q module to address the unique concerns of patients undergoing breast-conserving therapy (BCT). METHODS: Phase 1 involved qualitative and cognitive interviews with women who had BCT and clinical expert input to establish content for the BCT module. A field-test (phase 2) was performed, and Rasch measurement theory (RMT) analysis was used for item reduction and examination of reliability and validity. Validation of the item-reduced scales in a clinical sample (phase 3) was conducted for further assessment of their psychometric properties. RESULTS: Qualitative interviews with 24 women resulted in the addition of 15 new items across multiple existing BREAST-Q scales and the development of two new scales (Adverse Effects of Radiation and Satisfaction With Information-Radiation Therapy). Feedback from 15 patients and 5 clinical experts were used to refine the instructions, response options, and item wording. An RMT analysis of data from 3497 women resulted in item reduction. The final set of scales showed evidence of ordered response option thresholds, good item fit, and good reliability, except for the Adverse Effects of the Radiation Scale. Validity and reliability were further supported by the phase 3 data from 3125 women. CONCLUSIONS: The BREAST-Q BCT module can be used in research and clinical care to evaluate quality metrics and to compare surgical outcomes across all breast cancer surgery patients
