For example, when an independent factor structure was
created (using principal Component Analyses, Varimax Rotation, with Kaiser Normalization)
the structure provides limited support for independent interpretation of scale scores. In
fact, the data show that all the items load as expected. That is, they load highly on the factors
that define the scales (0.88 or 0.89 for the four factor solution and 0.67 to 0.88 on the fivefactor
solution) and low and trivially (below 0.29) on the other scales. Confirmatory factor
analyses may follow exploratory analyses in the initial stages of test development to better
define test structure. For ARIK-A, both four- and five-factor solutions are acceptable based
on chi-square indices (CMIN/DF), and root mean square error of approximation (RMSEA)
statistics, although the no rmed fit index (NFI) data show that the four-factor solution appears
to be slightly better (see Table 3). However, based on a follow-up analysis, the difference Assessment of adult educators' reading instructional knowledge
