Measurement validity in terms of reliability and
construct validity was evaluated. The reliability analysis was
conducted in order to ensure the internal validity and
consistency of the items used for each variables. (Zhang, Li,
& Sun, 2006), recommended that Cronbach alpha values
from 0.6 to 0.7 were deemed the lower limit of
acceptability. An alpha of more than 0.7 would indicate that
the items are homogeneous and measuring the same
constant.
