Acceptability and preparation for decision-making three months (t1) after study inclusion

The perceived usefulness of the DAs (assessed by the IG) compared to written information as part of UC (assessed by the CG) was measured using (a) an acceptability instrument and (b) the preparation of decision making scale (PrepDMS) at t1 and mean scores were built. In the IG, all scales reached statistically significantly higher mean scores than in the CG. Differences were tested by Pearson’s chi-square test. The number of participants was as follows: in the acceptability survey the IG had n = 202, the CG n = 187; in the PrepDMS survey subscore 1 the IG had n = 200, the CG n = 189; in the subscore 2 survey the IG had n = 203, the CG n = 190; in the total score survey the IG had n = 200, the CG n = 189
