Brief summary
This study evaluates the efficacy of a tailored telephone intervention to promote informed decision making about prostate cancer testing among predominantly immigrant black men.
Detailed description
African American and African-Caribbean men have the greatest prostate cancer incidence and mortality rate. Professional organizations provide conflicting recommendations regarding prostate cancer testing but generally agree that men learn about the risks and benefits of testing and share in decisions about testing based on their personal preferences. This study was designed to assess the effects of a decision support intervention on men's knowledge about prostate cancer testing, participation in medical decisions about testing, decision conflict related to testing, and the congruence between prostate cancer testing intentions and behaviors. A randomized controlled trial was conducted. Participants were randomized into one of two conditions: (a) tailored telephone education about prostate cancer testing (intervention group) or (b) tailored telephone education about national guidelines for fruit and vegetable consumption (attention control group).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| congruence between prostate cancer testing intention and behavior | 1 and 2 years post randomization | Congruence between men's stated intentions to get tested and their actual testing behavior, validated by medical claims at 1 and 2 year follow-up. Intention-behavior agreement was coded as congruent (1), whereas disagreement was coded as incongruent (0). |
| Knowledge about prostate cancer and prostate cancer tests | baseline and 8 months post randomization | 12 item knowledge index with questions on testing, risk factors and epidemiology, and treatment effectiveness and side effects. Percent correct was used as the outcome measure. |
| Decisional conflict | 8 months post randomization | Used a modified version of the 16 item Decisional Conflict Scale with the 3 level response category suggested for low literacy populations. |
| Verified doctor visit to discuss prostate cancer testing | 2 years post randomization | Visit with physician to talk about prostate cancer testing, with visit verified through medical claims records |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| State anxiety | baseline and 8 months post-randomization | Used a 7 item subscale of the Hospital Anxiety and Depression Scale. |
