Notes: Concerning reliability analysis, the results indicated better Cronbach’s alpha for all items since all values for consistency are greater than the threshold recommended which is 0.7. About the item total correlations, the adequate levels of Cronbach’s alpha for all items were found since the values are greater than 0.3 which is the cutoff. *Statistically significant and correlated at p<0.001.

Abbreviation: SD: standard deviation.
