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

Demographic interactive effects: The means of ordinal demographic variables were
compared between test factors and results are shown in Tables 8a and 8b. The study
population was mostly adult and mixed sex. Analysis of variance showed most
differences related to age of the study population: that studies using adapted tests were
least likely to match for age and sex in controls; nonart behaviourial or content measures
were used with younger subjects as were therapy groups, possibly reflecting recognised
difficulties in the interpretation of children's art 166 as the lesser success rate for
patient/nonpatient differences indicates; groups in studies using more criterion measures
tended to be older probably reflecting the greater level of disability measures given as
standard in this population, medical opinion on these groups and also the longer term of
their confinement.

Design of test levels by criterion: 31 studies used no other criterion measure than
diagnosis and the study test (Table 9) and these were mostly studies which found
differences (Table 2). The comparison of artwork for 1 criterion measure was broadly
