4.1.1. Questionnaire Reliability Test

The reliability coefficient, Cronbach's alpha, is used to measure the internal consistency or reliability of an instrument or questionnaire. This coefficient is often used for questionnaires developed using multiple Likert scales to determine whether the scale is reliable. We used Cronbach's alpha to determine the reliability using SPSSAU, resulting in a Cronbach's alpha value of 0.917 (Table 4), which indicated the good reliability and high internal consistency of this questionnaire for additional analysis.
