An Iterative Process for Developing and Evaluating a Computer-Based Prostate Cancer Decision Aid for African American...

Area of Science:

• Health Informatics
• Public Health
• Cancer Research

Background:

• Prostate cancer (PrCA) disproportionately affects African American (AA) men, highlighting the need for informed screening decisions.
• Developing culturally appropriate decision aids is crucial for this population.
• A computer-based decision aid (CBDA) was designed to enhance prostate knowledge, self-efficacy, and informed decision-making intentions.

Purpose of the Study:

• To develop and evaluate a culturally appropriate computer-based decision aid (CBDA) for African American men regarding prostate cancer (PrCA) screening.
• To increase prostate cancer knowledge, decision self-efficacy, and intention for informed decision-making.

Main Methods:

• An iterative development approach was used, incorporating feedback from focus groups with 21 African American men.
• A prototype CBDA with interactive elements was refined based on participant input.
• Expert reviewers and usability interviews were conducted to further evaluate the CBDA.

Main Results:

• Consensus was reached on many CBDA features between participants and expert reviewers.
• Suggestions for improving format and graphics were provided to enhance CBDA effectiveness.
• The development and evaluation process, along with implications, are discussed.

Conclusions:

• Computer-based decision aids (CBDAs) show potential for supporting informed decision-making among African American men.
• Community and expert engagement in an iterative development process is vital for creating relevant decision aids for priority populations.
