Abstract
Objective
To evaluate the impact of a web-based, plain language decision aid (CHOICES DA) on minority cancer survivors’ knowledge of cancer clinical trials (CCTs), readiness for making decisions about clinical trial participation, and willingness to participate in a clinical trial.
Methods
Participants were 64 Black and Hispanic cancer survivors from Miami, Florida. In a single arm intervention study, participants completed self-report assessments of CCT knowledge, decision readiness regarding clinical trial participation, and willingness to participate at three time points.
Results
Black and Hispanic participants did not differ on demographic characteristics. Post-test and follow-up measures of CCT knowledge and decision readiness were significantly greater than pre-test measures for the sample overall, and for Black and Hispanic participants separately. Few significant differences were observed between Black and Hispanic participant outcomes at each survey time point, and willingness to participate did not change overall and for either group independently.
Conclusions
Reviewing the CHOICES DA was associated with significantly improved knowledge and decision readiness to participate in a CCT immediately and at 2-week follow-up.
Practical Implications
These findings suggest that CHOICES DA may support informed decision making about CCT participation within an acute, yet clinically relevant window of time for minority cancer patients who are substantially under-represented in cancer research.
