†
The intercept can be interpreted as the average satisfaction of a (hypothetical) subject scoring 0 for each predictor in the model.
*
P < .05;
‡
0 = Dutch, 1 = other.
***
P < .001.
§
0 = preference for all information possible, 1 = less than all information.
||
0 = no, yes = 1.
¶
0 = male, 1 = female.

P < .01;
