Participants randomized to the THRIVE arm will be sent a link to access the THRIVE portal up to 3 weeks prior to their clinic visit. The THRIVE modules can take between 20-35 minutes to complete. Completion of the THRIVE modules prior to the clinic visit will be monitored and confirmed by study staff. Upon completing the program, a report summarizing the conversation and questions/comments brought up by the patient will be shared with their physician prior to the clinic visit.

Participants randomized to the education control arm will be sent a link to access the 2-page American Cancer Society (ACS) handout: "After a Thyroid Cancer Diagnosis." The handout can take between 5-15 minutes to read through. Completion of the ACS handout prior to the clinic visit will be monitored and confirmed by study staff.

THRIVE is a tailored AI agent that provides patient education and assists in decision-making specifically for thyroid cancer patients. Using HIPAA-compliant protocols and an empathic approach, THRIVE can (1) establish patient priorities, (2) guide patients through decision tools, and (3) integrate detailed notes into the electronic health record (EHR). Such computer-generated notes have been found to be higher quality, more comprehensive, better organized, and with greater relevance compared with physician-documented notes. Altogether, this solution tackles a time-intensive and laborious task, expanding time and bandwidth for decision-making. Moreover, integration with existing infrastructure like the EHR can help promote clinical adoption.

Thyroid cancer-related anxiety as measured by the 18-item TC-MAX questionnaire created by Dr. Allen Ho at Cedars-Sinai. It is a psychometric scale assessing thyroid cancer-related anxiety across three different subscales (Collective Anxiety, Ultrasound Anxiety, and Fear of Recurrence/Progression). Scale range is between 0-100, with higher scores indicating greater anxiety. Means and standard deviations will be used to describe the scores.

Decisional conflict as measured by the 16-item Traditional Decisional Conflict Scale (DCS) - Statement Format. This scale assesses personal perceptions of uncertainty in choosing options; modifiable factors contributing to uncertainty such as feeling uninformed, unclear about personal values and unsupported in decision making; and effective decision making such as feeling the choice is informed, values-based, likely to be implemented and expressing satisfaction with the choice. This questionnaire uses a 5-point Likert scale, from strongly agree to strongly disagree.

System usability as measured by the validated, 10-item System Usability Scale (SUS). This attitude Likert scale gives a global assessment of usability. Each item is rated on a scale of 0 to 5, with higher scores indicating greater usability.
