Background/Method. Decision aids have not been widely tested in diverse audiences. The authors conducted interviews in a 2 x 2 race by education design with participants who were 50 years old (n = 188). The decision aid was a benign prostatic hyperplasia videotape. Results. There was an increase in knowledge equal in all groups, with baseline knowledge higher in whites. The decision stage increased in all groups and was equivalent in the marginal-illiterate subgroup (n = 0.15). Conclusion. Contrary to expectations, results show no difference by race or college education in knowledge gain or increase in reported readiness to decide. The video appeared to produce change across race and education. The end decision stage was high, especially in less educated men. Results suggest that decision aids may be effective without tailoring, as suggested previously to enhance health communication in diverse audiences. Research should test findings in representative samples and in clinical encounters and identify types of knowledge absorbed from decision aids and whether the shift to decision reflects data/knowledge or shared decision-making message.
