1. Analyzing Data Using SPSS (Reliability)

13. 672 cases (observations/respondents) were used in the calculation of Cronbach’s alpha

14. The obtained alpha score is 0.915, which indicates that the scale has high internal consistency (reliability)

15. Under the “Cronbach’s Alpha if Item deleted” the reliability of 0.915 is the highest, so it is not necessary to delete any of the items to improve the reliability score of this scale
