Quality of drawing as a factor in the interpretation of figure drawings.

Examined the drawings of 32 poliomyelitis patients and their matched controls to see whether figure drawings primarily reflect the subject's projection of psychological state, ability to draw, or some combination of these two factors. An overview of the literature is also given. Drawings from disabled and nondisabled subjects were reliably rated for quality, with no significant quality difference found between groups. Analyses of variance were then used to compare the drawings on several different measures of drawing size, completion and movement that might be assumed on the basis of the literature, to reflect the subjects' projection of disability status. Results showed that quality of drawing was a significant factor in 13 of the 17 comparisons while disability status proved to be a significant factor in only one of the 17 comparisons. There were no significant interactions. Therefore, the overall findings are consistent with the hypothesis that quality of drawing-rather than projective mechanisms-may at times be the overwhelming determinant of clinical and research findings with figure drawings.
