Thus, 5 factors and 22 items were determined. 7 point Likert scale was revealed to be a good fit. The result of Confirmatory Factor Analysis for the data of second survey revealed that Construct Validity of 5 factors and 22 items was valid and reliability was high by recording Cronbach’α value .954.
