Study Summary

What Matters Most is a study that aims to determine how best to help women of lower socioeconomic status make high-quality decisions about early stage breast cancer treatments. What Matters Most will be comparing two decision aids used in the clinic visit to usual care (what normally happens in the clinic). The first decision aid (Option Grid) presents evidence-based information about lumpectomy and mastectomy in a tabular format using text only. The second decision aid (Picture Option Grid) presents evidence-based information about lumpectomy and mastectomy using pictures, pictographs and simplified text. What Matters Most aims to show that the interventions can reduce disparities in decision-making and treatment choice between women of high and low SES.

Primary Outcome

Change in decision quality, measured using the validated 16-item Decision Quality Worksheet for Breast Cancer Surgery. Decision quality is measured through three constructs: knowledge, decision process, and concordance. Knowledge is five questions that results in a score from 0 to 5 with higher numbers indicating higher knowledge. Decision process is a measure how much shared decision making process occurred, based on patient-report. It is a seven-item scale with higher numbers indicating higher
