measurements, favouring the Draw-a-person protocol. <strong>The</strong> comparison was<br />

predominantly developmental, which category was absent from the tests which showed<br />

associations; cognitive measures were also popular and least popular was emotion, which<br />

was most popular in the test which showed associations.<br />

Summary: <strong>The</strong>re were many more tests which showed associations with the criterion<br />

measure, but almost half the tests employed no other criteria than clinical diagnosis.<br />

However, the relationship <strong>of</strong> the diagnostic criterion to the <strong>art</strong> test was consistent with<br />

the comparison made by the study (on diagnosis), whereas the majority <strong>of</strong> the measures<br />

which employed another measure were achievement tests and their comparison was <strong>of</strong>ten<br />

not consistent with the orientation <strong>of</strong> the <strong>art</strong> test (37% compared achievement tests on<br />

diagnostic or emotional criteria). If the tests using only the diagnostic criteria were set<br />

aside, there are 2 points to note:<br />

(1) Tests which compared developmental qualities in drawings showed no association<br />

with criterion measures; and<br />

(2) Tests which compared emotional qualities tended to show association with<br />

criterion measures.<br />

<strong>The</strong>re were equal numbers <strong>of</strong> studies on both sides for tests which compare cognitive<br />

aspects. <strong>The</strong>se results confirm the recognised doubts about the validity <strong>of</strong> painting or<br />

drawing tests as developmental measures for psychiatric populations discussed in<br />

Chapter 1, and so their predictions <strong>of</strong> cognitive function and use in place <strong>of</strong> IQ tests.<br />
