The psychopathology of everyday art: a quantitative Study - World ...

spread between subjective and objective scales but with the addition of 1 other criterion
measure, the number of content measures dropped and behaviour measures increased.
For 3 or more measures (n=11) (which were equally split - difference/no differences),
tests favoured objective comparison of countable items (n=7), although there were some
content measures, there were no mixed comparisons. So, the observable and countable
measures tended to use more criterion measures, the mixed formal and content measures
used less criterion measures.

Test derivation and result levels by judges: The vast majority of studies (35) used
only one rater and 13 used established tests (Table 10), most of which found differences.
Thus, reliability was not established for 22 tests, of which most found no differences.
There were fewer tests using more raters, but the majority of 2-rater tests (n=7; 78%)
were developed for the research; half reported differences. All 7 tests with more raters
