Construct validity was also tested with a principal component
analysis with varimax rotation and Kaiser Normalisation. The
obtained value for the Kaiser–Meyer–Olkin measure of sampling
adequacy was 0.74, and the Bartlett's test showed pb0.001, signifying
an adequate sample and a sufficient minimum sample size for
performing this factor analysis (Pett et al., 2003). The obtained factors
were named in a way that intended to show the substantial content
in them. The Cronbach's alpha coefficient was computed for each
obtained factor.
