140 Chapter 7 39%, n=114). Differences in regret between trial arms at both time points did not reach statistical significance (Table 2). Within the DA group, mean regret was significantly lower at T3 compared to T2 ( M =13.5 vs M =17.4, t (179)=2.30, p =.02). At both time points of follow-up, most participants were (very) satisfied with their treatment, regardless of trial arm. Information satisfaction was lower for participants from the DA group compared to the control group immediately after treatment decision-making ( M =70.8 vs M =77.8, t (200.5)=3.02, p =.006), but there was no difference between trial arm groups 6 and 12 months later (Table 2). The perceived patient-doctor relation was equal across trial arms (Table 2). Table 2.
