To measure respondent’s level of knowledge and opinions, sixteen items on knowledge and fourteen items on opinions were presented to the respondents. In knowledge
section, the first two items were measured using the multiple-choice question. Meanwhile the rest of the items in knowledge section were measured using 3-point Likert
scale where 1 = agree; 2 = not sure and 3 = disagree. On the other hand, in opinion
section, fourteen items were asked using a 5-point Likert scale where 1 = strongly
disagree; 2 = disagree; 3 = neither agree nor disagree; 4 = agree; 5 = strongly agree.
A Cronbach’s Alpha test for internal consistency revealed a coefficient of 0.738
and 0.943 for items regarding knowledge and opinions respectively. According to
Tavakol and Dennick (2011), there are different reports about the acceptable values
of alpha, ranging from 0.70 and 0.95. Thus, the internal consistency reliability of the
measures used in this study is acceptable as both variables scored above 0.7. Data
were analysed using the SPSS software. Data then were summarised using means
and standard deviations.
