Figure 2. Locus of decision-making control (N = 431).

Note: The figure shows patient-reported decision-making control by study group. A smaller percentage of control patients reported being in control of their decision making than did Web site patients (P₁ = .03) or brochure patients (P₂ = .03) when responding to the question, "How was the decision made today on whether to do a PSA blood test? (A) I made the decision on whether to order a PSA test. (B) I made the decision about whether to order a PSA test after seriously considering my doctor’s opinion. (C) My doctor and I shared the responsibility for deciding whether to order a PSA test. (D) My doctor made the final decision about whether to order a PSA test after seriously considering my opinion. (E) My doctor made the decision whether to order a PSA test." Previsit education did not increase the frequency of a shared locus of decision-making control (choice C).
