Study summary

An electronic decision aid will be used to assist individuals in choosing a multi-gene panel with their medical oncologist instead of a genetic counselor. A decision aid may facilitate quality decisions around the selection of a specific multi-gene panel without a genetic counselor. Upon completion of the decision aid, participants will be asked to indicate their decision about whether to pursue genetic testing and which specific multi-gene panel to pursue. A survey will then be administered to assess participants' opinions on the decision aid.

What researchers measure

Primary outcomes

  1. Participant Satisfaction With How Educational Information is Presented in the Decision Aid

    Measured with 6 items on a questionnaire that asks participants to rate the way certain information is presented on the decision aid. Each item is rated on a scale of 1 to 4, with 1 being poor and 4 being excellent.

    Time frame: This outcome will be measured immediately following completion of the decision aid. The average completion time of the decision aid is 14 minutes.

Secondary outcomes

  1. Total Time Spent on Decision Aid

    The total amount of minutes spent on the decision aid

    Time frame: From the start of the decision aid to the completion of the decision aid

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 13, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
