¹ranging from 1 – 5 in which higher scores indicate more satisfaction.

²p-levels for differences between doctor, shared and patient, tested with the Kruskal-Wallis test.

³p-levels for differences between too little, enough and too much participation, tested with the Kruskal-Wallis test.

^{a or b}Distributions are significant different from each other (post hoc test with Mann Whitney with Bonferroni correction).

*Significant on the .05 level.

**Significant on the .01 level.
