NCT04372888

Brief Summary

The goal of this application is to gain a deeper understanding of decision-making for genetic testing and identify effective choice-architecture-based strategies to improve decisions in genetic testing. The investigators hypothesize that choice architecture (i.e. framing) affects decision-making for hypothetical genetic testing scenarios.

Conditions

Outcome Measures

Primary Outcomes (3)

  • Genetic testing decision

    Opting "yes" for genetic testing or "no" refusing genetic testing

    after reading the scenario and viewing frame (approximately 10 minutes)

  • Satisfaction with Decision Scale (SWD)

    SWD is a validated 6-item instrument, items are scored on a 1-5 scale with higher scores indicating greater satisfaction with the decision taken

    study completion (approximately 30 minutes)

  • Decisional Regret Scale (DRS)

    DRS is a validated 5-item instrument, items are scored on a 1-5 scale with higher scores indicating more regret with the decision taken

    study completion (approximately 30 minutes)

Secondary Outcomes (2)

  • Newest Vital Sign (NVS)

    study completion (approximately 30 minutes)

  • Experience with genetic disease

    Baseline (study onset)

Study Arms (2)
