Preliminary findings show a small number of respondents and the respondents are not representing the sampling unit becomes a problem to generalize the result. As a result, this paper provides very low item reliability and person reliability is acceptable. Therefore, more feedback from respondent is needed in order to increase the item and person reliability.
