Collecting of 340 participants is required to complete this
research. Data for this study were collected from people who
are at least in one of the researchers’ Facebook friend list and
live in Thailand. Survey questionnaires were distributed to
randomly selected people, and were either conducted by
personal interview or internet. With the above criteria,
convenience sampling is done for the sampling purposes, as
this method is considered by far the easiest, fastest, and most
efficient way to collect the needed information at the
moment.
