lines ranged from 0-thin and a little higher in drawn lines, indicating a greater proportion
of zero scores (lack of use).
Painted line: Only schizophrenic pictures showed association of line with colour: either
painted lines were red and green, or they were inconsistent in colour and bright green or
red was consistently present for some other reason. This provides an opportunity for
further investigation for clinical utility.
There may have been an element of lack of control of paint by patients and
especially substance abusers, who scored least, which was concealed by the non-use of
painted line by patients, although controls' use was still low. The order of scores for
drawn line was the opposite of that for painted and there was a strong negative
correlation between painted and drawn line in every group except substance abusers (who
used the least painted lines and the most drawn) thus subjects used either drawn or
painted line, not both at once.
Drawn Line: Controls should have been mid-range in drawn line, but instead, scored less
than other groups. In fact, the confidence interval for controls remained consistent
through painted or drawn lines, it was the patients' strategies that changed (this further
supports the division of drawn and painted line for patients). It is possible that thick and
thin lines were always scored together (varied = 2) so reducing the mean score to neutral,
but most groups scored in the 0-1 range indicating a greater proportion of 0 scores (no
line present). Drawn lines were more prevalent in substance abusers and patients with
personality disorder.
