This study shows that the iDecide tool significantly improved prostate cancer knowledge and decision-making confidence in African American men. The intervention also boosted technology use confidence, with most participants intending to make informed screening decisions.
Area of Science:
- Health Informatics
- Public Health
- Cancer Prevention
Background:
- African American men have a higher risk of prostate cancer.
- Effective decision aids are needed to support informed screening choices.
- Technology-based interventions can potentially bridge health disparities.
Purpose of the Study:
- To evaluate the impact of the iDecide decision aid on prostate cancer knowledge.
- To assess changes in informed decision-making and technology use self-efficacy.
- To determine the intention to engage in informed decision-making among African American men.
Main Methods:
- A one-group, pretest/posttest design was employed in community settings.
- Participants (n=354) were African American men aged 40+ without prior prostate cancer diagnosis.
- The iDecide intervention, an embodied conversational agent-led decision aid, was utilized.
Main Results:
- Significant improvements were observed in prostate cancer knowledge (P ≤ .001).
- Informed decision-making self-efficacy and technology use self-efficacy significantly increased (P ≤ .001).
- 67% of participants reported an intention to engage in informed decision-making.
Conclusions:
- Embodied conversational agent-led decision aids effectively enhance prostate cancer screening decision-making capacity.
- The iDecide intervention improved knowledge, self-efficacy, and intention for informed decisions.
- Future research should explore interventions for men without prior screening history.
