Participant Flow

Potentially eligible participants were identified via the electronic health record at Medstar Georgetown University Hospital. The first participant was enrolled in February 2020 and the last participant was enrolled in March 2021.

Of 216 potentially eligible participants, 112 completed the baseline survey and were randomized. Five participants were found to be ineligible after randomization (i.e., protocol violation). Thus, the final sample was comprised of 107 men who were randomized to ST (n=53) vs UC (n=54).

Measure
Proactive Streamlined Genetic Education and Testing
Participants randomized to this arm will proactively receive genetic education print materials and the option to proceed directly with genetic testing. Proactive Streamlined Genetic Education and Testing: This intervention consists of the proactive delivery of genetic education print materials followed by streamlined and facilitated access to genetic testing.
Usual Care
Participants in this arm will be sent a referral letter recommending that they schedule a genetic counseling session and providing them with contact information to do so. Usual Care: This intervention consists of a standard genetic referral letter that notified the participant that he qualified for genetic referral, recommends the scheduling of a genetic counseling session and provides a telephone number for scheduling.

SECONDARY outcome

Timeframe: 3 Months Post Randomization

Population: Participants completing the 3-month follow-up assessment. Three participants who completed the 3-month follow-up failed to complete this scale. Thus, the final sample size for this analysis was N=103.

Satisfaction with Decision Scale Higher values indicate greater satisfaction with the genetic testing decision. Range = 6 to 30.

Population: Total number of randomized participants who completed the PROMIS depression and anxiety measures

Patient Reported Outcomes Measurement Information System - Depression Short Scale 6A T-Scores (Mean = 50 and SD = 10; Range = 38.4 to 80.3) Higher scores indicate greater depression Patient Reported Outcomes Measurement Information System - Anxiety Short Scale 6A T-Scores (Mean = 50, SD = 10; Range = 39.1 to 82.7) Higher scores indicate more anxiety
