First, the vignette test was administered.
The Conflicting Beliefs and Emotions vignettes were tested with a Kruskal-Wallis test with the separate mean scores on the vignettes as dependent variables.
In the end, 24 vignette pre-test and post-test measurements and 25 determinant questionnaires were available for analysis.
It is a vignette-based test requiring that participants depict violations of social norms using eight sample situations.
Alteration of the stimulus format, or question, to include contextual vignettes allows testing of higher cognitive levels and problem-solving ability [ 3, 8, 34].
We ran two focus groups to determine the potential key factors affecting desire to receive genetic information which could then be varied in the vignettes and tested for their influence on attitudes.
We plan additional psychometric testing; the next step includes a series of case vignettes to further test the items of the instrument, which will be followed by testing with real patients.
Differences between the test vignettes were all statistically significant for both ANOVA and Friedman's test (p < 0.001 for all comparisons) (See Table 2).
No authors reported testing vignettes on persons with AD or their caregivers.
The normality of distribution of the vignettes' RI was tested and confirmed with one-sample Kolmogorov-Smirnoftest.
