The Peer Genetic Study

January 23, 2026 updated by: Thomas Jefferson University

Peer-Based Intervention for Genetic Evaluation for Prostate Cancer Among African American Men: The Peer Genetic Study

This trial studies how well a peer-based health education program works in reducing barriers and changing attitudes and beliefs of prostate cancer genetic screening in African American participants with or without a previous personal or family history of prostate cancer. Participating in a peer-based health educational program may help participants learn more about prostate cancer and how their personal or family history of disease may increase their risk of prostate cancer.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in of decisional conflict
Time Frame: Baseline up to 2 months
Will be assessed by the 4-item Sure of myself; Understand information; Risk-benefit ratio; Encouragement (SURE) scale. To compute a summary decisional conflict score, the Likert-scaled responses will be averaged across the SURE item responses provided by a subject completing at least 2 of the 4 questions. The change in decisional conflict scores between baseline and endpoint at 2-months will be calculated and group means for these changes compared between subjects randomized to receive control materials vs. those randomized to receive the peer health education intervention (i.e., by intention to treat). The significance of the difference will be evaluated at the 0.05 level using a two-sided Student's t-test. The assumptions for this test will be carefully evaluated. If the changes are substantially skewed, they will be summarized with group medians and evaluated for significant differences by the nonparametric Wilcoxon's rank sum test.
Baseline up to 2 months
Awareness of risks and benefits of genetic testing
Time Frame: Up to 2 months post study
Will be summarized in tables with descriptive statistics or graphically in data plots at each time they are assessed along with changes in responses over time. Will investigate imbalances in these data for potential confounding of primary and exploratory endpoint analyses and investigate disparities and intervention effect modification in various subgroups of subjects.
Up to 2 months post study
Perceptions of genetic testing
Time Frame: Up to 2 months post study
Will be summarized in tables with descriptive statistics or graphically in data plots at each time they are assessed along with changes in responses over time.
Up to 2 months post study
