Prostate Cancer Clinical Trial
Prostate Cancer Genius App Education and Home-based PSA Screening for African American Men
Summary
Prostate cancer is the most diagnosed cancer in African American men and the second-leading cause of cancer-related death. The prostate-specific antigen (PSA) test is an early detection screening measure for prostate cancer. Greater PSA uptake among African Americans may reduce the disproportionate mortality burden of this disease. However, knowledge about prostate cancer and uptake of PSA screening remain low among African American men. To address this inequity, innovative team science approaches are required. This project proposes to develop and test the first-of-its-kind Prostate Cancer Genius App to improve knowledge of prostate cancer risk and symptoms, and deliver tailored navigation to complete a home-based PSA test. The primary goal of this study is to evaluate the feasibility of the Prostate Cancer Genius App in a 30-day pilot randomized control trial compared to an existing app developed by the U.S. Department of Health & Human Services (Prevention Taskforce App). African American men from Oklahoma, aged between 55 and 69 (N = 80), eligible for the PSA test will be randomly assigned 1:1 to receive either app. Three dimensions of app feasibility will be assessed: (1) preliminary efficacy, evaluated via post-intervention differences in prostate cancer knowledge, (2) app engagement and accessibility, measured via self-report questionnaires, and (3) app acceptability, explored via semi-structured qualitative interviews. Finally, the investigative team will explore post-intervention PSA screening rates and identify predictors of screening/not screening across both arms. The successful demonstration of feasibility for the Prostate Cancer Genius App within Oklahoma will support expanding this intervention to African Americans nationwide.
Full Description
Prostate cancer is the most diagnosed cancer in African American men and the second-leading cause of cancer-related death. Disparities in prostate cancer for African American men have persisted for almost half a century, and these health disparities are among the most extreme of all cancers in the United States. The prostate-specific antigen (PSA) test is an early detection screening measure for prostate cancer. Greater PSA uptake among African Americans may reduce the disproportionate mortality burden of this disease. However, knowledge about prostate cancer and uptake of PSA screening remain low among African American men. The process of informed and effective decision-making is heavily underpinned by adequate knowledge levels of the disease and screening benefits and risks, with lower knowledge levels reported among African American men. This project will test the feasibility of a first-of-its-kind Prostate Cancer Genius App (herein referred to as Genius App) to improve knowledge of prostate cancer risk and symptoms. PSA testing is not appropriate for all men, so the Genius App will support informed decision-making with a healthcare provider. The Genius App will also provide novel tailored navigation to complete a home-based PSA test for men who opt to screen. To test the app, 80 African American men from Oklahoma (aged 55 and 69) who are not up to date with PSA screening will be randomly assigned 1:1 to use either the Genius app or an existing U.S. Department of Health & Human Services app (herein referred to as the Prevention Taskforce App) for 30 days.
Aim 1. Evaluate the preliminary efficacy of a prostate cancer prevention app on prostate cancer knowledge (primary outcome).
Hypothesis: Participants (n = 40) randomly assigned to the Genius app will report significantly greater knowledge about prostate cancer post-intervention than participants (n = 40) randomly assigned to the Prevention Taskforce app at 30 days post-randomization.
Aim 2. Explore the perceived engagement, accessibility, and acceptability of a prostate cancer prevention app.
The investigative team will explore: (i) the extent to which participants find the Genius App engaging and accessible compared to the Prevention Taskforce app via validated self-report questionnaires and app metadata; and (ii) the perceived acceptability of the Genius App by conducting semi-structured interviews (n=40) with participants to acquire in-depth descriptions of their experiences with the app at the end of the study.
Aim 3. Derive preliminary estimates of the effects of a Genius App on PSA screening test completion rates and identify mechanisms of screening adherence.
The investigative team will (i) explore differences in PSA test completion rates, including in-clinic and home-based PSA testing, between the Genius app and the Prevention Taskforce app and (ii) identify whether changes in key variables in weekly smartphone assessments predict completing a PSA test.
