After inspection of item characteristics and analyses of the hypothesized latent 18-factor structure of the 90-item preliminary version of the DISC, a 36-item short form was compiled, consisting of two items per schema using the criteria for item selection (factor loadings, standardized residuals, item distribution, and item difficulty).
However, inspection of item thresholds in the pooled dataset showed these items to be ordered and they were not rescored.
Inspection of item performance resulted in discarding three items from the child version, so that the field test version included 50 items.
After initial inspection of item total correlations and a scree plot, we extracted components with eigenvalues over 2, which were then rotated using Varimax rotation.
The items in the resulting scales, judged by the size of Loevinger's coefficient, were analysed for violations of monotony, 95% confidence intervals and invariant item ordering, including inspection of item pair plots.
Inspection of item pair plots showed that the IRF for item 1 in this scale was positioned far from the remaining items and could be contributing to the high IIO; removing item 1 and re-analysis of the scale properties reduced HT to 0.42 but the scale remained strong at Hs >0.70.
While the PANAS has been previously associated with self esteem and inspection of individual items showed the highest loading items were self-referent, our self esteem hypothesis nevertheless remains tentative until replicated with a specific measure of this construct.
Inspection of the items in our sample revealed that all ten reversely keyed items showed negative and low item-total correlations (range −.40 to −.13).
Protective measures at popular tourist sights such as the statue of Christ the Redeemer atop Corcovado Mountain here and the churches and colonial buildings of northeastern Brazil remains at normal levels, with no inspection of personal items.
