In this study, a questionnaire's reliability was further verified by using Cronbach's alpha coefficient (α), which is a measurement of internal consistency. This reliability test was conducted on a small group of respondents who were requested to complete a final questionnaire. A total of 30 respondents were involved in the reliability test. To obtain α, the Statistical Package for Social Sciences (SPSS) software program was used to analyze raw data. The value of the alpha coefficient for the data obtained from the respondents was 0.746, demonstrating acceptable reliability of the questionnaire (Nunnally, 1978). The results of these analyses implied that the actual data collection could be performed by using this questionnaire.
