III. METHODOLOGY
A. Participants
Data were collected from throughout Malaysia via a
self-administered questionnaire carried out between
November 2012 and March 2013. Target respondents were
adults 18 years old above and were randomly approached at
major shopping malls in 14 capital cities and Federal
Territory of Kuala Lumpur. Shopping malls can be regarded
as the most appropriate place to collect data because there is a
high probability of getting people from all walks of life to
participate in the survey. The malls were chosen randomly
from the list of Malaysian business directory. Respondents
were asked whether they would like to participate in the
survey. Non-monetary incentive was given to each
respondent upon completion of the questionnaire.
