Characteristics of House-Tree-Person drawings by college men and women.

Summary H-T-P drawings of 393 men and 457 women were coded on 73 variables specified in the H-T-P literature. In order to provide extensive normative data, reliability of coding was determined by having 47 drawings evaluated by two different judges. Median agreement was 91.8%. Consistency of the 73 variables was investigated by obtaining a second drawing from 49 men and 87 women following an interval of from four to six weeks. Except for a few individuals there were no marked changes. Twenty-nine items (about 40%) showed significant differences in incidence between the sexes. Comparisons of these data with data from other studies were reported.
