4.2 Reliability Test
The reliability test determines if the scale is consistent or error-free (Barrett and Morgan, 2015). The goal of employing the reliability test
in research is to ensure that the response does not vary over time, so that the test is reliable at any moment. Cronbach's alpha is generally
used to measure internal consistency reliability, but it can also be used as a conservative computation in PLS-SEM (Wong, 2013). Cronbach's
alpha and composite reliability can be used to assess reliability (CR). In the study, both measures are utilised to determine the consistency of
all elements and to assess the reliability of the measurement data collected. Then, an alpha coefficient test of the Cronbach's and composite
reliability are utilised to assess the reliability of the scales approach used in this study (CR). According to Chin (1998), an appropriate model
requires a CR value greater than 0.70; hence, the Cronbach's alpha in this study aims to fall within this range. According to Fornell and
Larcker (1981) and Cheah et al. (2018), CR values greater than 0.70 are acceptable and reasonable. The reliability value is 0.70, with higher
values indicating greater reliability (Pallant, 2005). If the value of CR is 1, it signifies that the expected reliability is perfect. The greater the
coefficient, the higher the reliability, as shown in Table 4.1.
Alpha Coefficient Range Status
0.90 and above Excellent
0.80 to 0.89 Good
0.70 to 0.79 Acceptable
0.60 to 0.69 Questionable
0.50 to 0.59 Poor
Below 0.59 Unacceptable
