Moreover, according to Nunnally (1978), to assess the reliability of the survey instrument, the inter-item analysis can be used to test the scale’s internal consistency. Hence, Cronbach's alpha is considered an adequate indicator of the internal consistency and the reliability of the survey instrument. The test shows that the Cronbach’s alphas range from 0.708 to 0.754, which exceed the minimum value of 0.7 to be acceptable (Sekaran & Bougie, 2010
