The HTP as a measure of change in dialyzed schizophrenic patients

Used the House-Tree-Person as a measure of pathology in 10 schizophrenic patients of both sexes between the ages of 19 and 30 before and after experimental hemodialysis treatment. Results obtained through the quantitative HTP scoring method, and reflected in HTP IQs, indicate that significant improvement as a function of treatment is seen in pre- to post-dialysis drawings. Data analysis, using the Two Factor Repeated Measures Analysis of Variance (ANOVA), indicates that drawings done after dialysis improve at the .005 and .001 levels. The HTP evaluations support the continued use of hemodialysis as an effective treatment for schizophrenia.
