The reliability of Riding's Cognitive Style Analysis Test

The reliability of Riding's popular Cognitive Styles Analysis test (CSA) was examined by comparing performance on the original CSA test and a new parallel version. Fifty participants completed both test versions twice, with the second sitting approximately a week later. Reliability was measured using parallel forms, test-re-test, and split-half analysis. Correlations of the verbal-imagery (VI) and wholist-analytic (WA) ratios from both test versions (original and parallel) were low (Range r = 0.07 to r = 0.36, Mean r = 0.24.). When the CSA and parallel form data were combined however, split-half analysis of the WA style ratio was stable (Mean r = 0.69) but the VI style ratio remained unreliable (Mean r = 0.36).
