appointment with doctors or had finished it. Research-
ers explained the study, including purpose and proce-
dure, and offered them opportunities to ask any
questions about the study. Because participation in the
survey was voluntary, data were collected only when
a patient agreed to participate in the study. Written
informed consent was gained from all participants, and
they were reassured of confidentiality and anonymity.
Each participant completed the questionnaire before or
after being examined by the clinician. A researcher was
present to assist if there were problems completing the
questionnaires. Participants required approximately
20–25 min to finish the questionnaire.
