Participants were recruited from May 2011 to
May 2012. They were asked to complete a
demographic data sheet and an information sheet
was provided to explain the study purpose and
procedure. Written informed consent was obtained on
a voluntary basis and privacy and confidentiality were
guaranteed. Participants were informed that their
names and the content of the interviews would be
used for the study alone and would not be exposed to
the public. All research documents were confidential
and kept in a locked filing cabinet accessible only
to research staff. The content of the interviews was
destroyed on completion of the study.
