121 Perceived Shared Decision Making Perceived SDM was significantly lower in the intervention group compared to usual care (between-group difference: 8.9 [95% CI, 0.6-17.1]) (Table 2). Additional adjustment for comorbidity yielded a comparable non-significant between-group difference (8.4 [95% CI, ‑0.0-16.8]). For the 11 intervention patients with a TOC planned according to protocol, perceived SDM was comparable to the control group 66.5 (±27.2) versus 67.9 (±26.1) respectively. Received information Levels of perceived information provision in the two study arms did not differ for all topics: “Disease”, “Medical tests”, “Treatment”, “Other services”, “Places of care”, “Self-help”, “Satisfaction with the amount of information”, and “Helpfulness of information” (Table 2). Self-efficacy Self-efficacy in the intervention group improved significantly from baseline to T1, with a mean difference of 1.1 (95%CI, 0.4-1.8). For the control group this within mean difference was 0.5 (95% CI, -0.1-1.2). No significant between- group difference was found: 0.4 (95% CI, -0.4-1.1) (Table 2). 5
