Participation
One hundred subjects signed up; four withdrew. Thus 96 out of a
potential number of 694 staff (13.8%) took part. Two of the 96 (2%)
subjects were males in a faculty in which the percentage of male staff
is 23.5%. Seventy-four participants filled in the pre-study survey and
fifty-nine the post-study survey. Of these, 44 could be identified from
both questionnaires using dates of birth or pseudonyms therefore the
data reported here concerns these 44 participants and paired student’s
t-test was applied to determine significance of changes.
