The research dealing with the reliability of the Rosenzweig Picture-Frustration Study is surveyed. Analysis of various split-half, and retest procedures are reviewed and their relative effectiveness evaluated. Reliability measures as applied to projective techniques in general are discussed.

Data are presented on the retest and split-half reliability of the Rosenzweig Picture-Frustration (P-F) Study, Children's Form, for two groups of subjects (aged 10-11 and 12-13), each group tested twice at an interval of three months. Reliability by retest was consistently higher than by the split-half method. (Author/CTM)

The reliability of measures of need for achievement can be improved by increasing the number of items and by using different scoring systems and stimulus materials. (MLP)

Achievement motivation was successfully measured among male and female college students by having the students rate eight Thematic Apperception Test cards for similarity and scaling the results in two dimensions: number of persons and degree of strong affect. The Rorschach Inkblot Test was not effective in determining need for achievement. (CTM)

Rorschach test protocols for a matched sample of male and female subjects, in the child and adolescent range, were scored for total responses. The data was analyzed for evidence of interactions between sex of experimenter and sex and age of subject. (Author/BJG)
