The seven-graded semantic differential scale was
organized into three groups: answers 1 – 2 were presented
as unimportant, 3 – 5 as neither important nor
unimportant, and 6 – 7 as important. The answers were
analyzed descriptively according to previous studies
(9,10,17,19). The response rate for each individual
question was set to 100%. This was done because not
all questions were applicable for all respondents.
