Abstract

Treatment decision making (TDM) in oncology is complex. Understanding treatment information is essential for shared TDM. Research suggests many patients have low numeracy. This mixed methods study explored numeracy and experience with numbers in a sample of individuals diagnosed with follicular lymphoma. Participants completed questionnaires (N = 32) and interviews (N = 20) assessing numeracy, decisional conflict and regret, and number preference. Results suggest that mean objective numeracy was relatively high, and most reported high confidence in numerical ability. Most participants preferred to receive numbers during the TDM process. There was no relationship between numeracy and decision outcomes. Future research should investigate the use of numeracy measures in practice and the impact of patient preferences and beliefs on shared TDM.
