MyPref: pilot study of a novel communication and decision-making tool for adolescents and young adults with advanced cancer.

PURPOSE Adolescents and young adults (AYAs) with cancer report feeling ill-informed about their cancer treatment options. Tools are needed to inform AYAs about treatment choices and amplify the AYA's voice in medical decision-making. We developed MyPref, a conjoint-analysis based tool that quantifies AYA preferences for future cancer treatments. METHODS We conducted a staged pilot study of MyPref utilizing an intervention mixed methods design. AYAs and their parent or trusted person (PTP) completed MyPref and received a summary report of their preferences for treatment-related factors. Participants later completed the Preparation for Decision Making Scale and MyPref Experience Questionnaire and engaged in semi-structured interviews. Oncologists reported on the perceived accuracy and utility of MyPref. We used a weaving technique for presenting mixed methods data. RESULTS Fifteen AYAs with advanced cancer, 7 PTPs, and 12 providers participated in this pilot; 32 (94%) completed all study items. AYA/PTPs stated study participation was useful and believed MyPref allowed for improved understanding of treatment factors and consideration, organization, and visualization of preferences. All providers agreed that MyPref made them think about patient's preferences and 9 (75%) reported they planned to change their approach to discussions about preferences for future treatments. CONCLUSION MyPref is an objective way to estimate AYA and PTP preferences for future treatment characteristics. This novel tool may be a useful way to engage AYAs and PTPs in discussions around preferences for treatment and prepare AYAs for future decision-making. We are currently evaluating this tool longitudinally to determine the impact on actual treatment decisions.
