Subjects & methods
Subjects
A convenience sampling method was adopted. The questionnaire was built
on Questionnaire Star and distributed online. In total, 523
questionnaires were recovered; 22 questionnaires with excessively short
response times and obvious errors were deleted, and 501 valid
questionnaires were ultimately obtained, for an effective rate of
95.7%. Among the respondents, 194 (38.7%) were males and 307 (61.3%)
were females. The age distribution was as follows: 15 respondents were
under 18 years old (3%), 340 were between 18 and 30 years old (67.9%),
46 were between 31 and 40 years old (9.2%), 73 were between 41 and 50
years old (14.6%), and 27 were over 50 years old (5.4%). The specific
information is shown in table 1.
