The purpose of this synthesis study was to assess the reliability and validity of the Draw-A-Scientist Test (DAST) and its variations across multiple studies, aiming to understand limitations and propose modifications for future application within and beyond the science domain. Given the existence of multiple DAST versions, this study quantified…

The Draw-A Scientist Test (DAST) has been used for many years as a data collection tool in studies where the image of the scientist is attempted to be determined. In this test, in which the image of scientist is attempted to be revealed with drawings, the drawings are analyzed using a coding ruler or checklist. However, the DAST has been…

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. (Author/DEP)

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)

Concludes that individuals can consciously introduce false projections while inhibiting true projections, thus affecting the theory of projection and the use of projective techniques for personality assessment. Since projective responses are subject to conscious control and distortion they are not reliable. (Author/EK)

The reliability and validity of using the drawings of the House-Tree-Person technique to assess the personality of prelingually deaf persons was evaluated with 33 deaf young adults. Interrater reliability was established for four scales and validity established for five personality traits (aggression, impulsivity, immaturity, egocentricity, and…

An instrument for identifying disturbed and normal third to fifth grade children was evaluated. The instrument employs verb choices in a forced-choice sentence-completion format. A cross-validation procedure established high percentages of correct classifications. (Author/JKS)

During the course of investigations on such topics as the instructional styles, interaction patterns and personality characteristics of teachers, the organizational structure of schools, the technology of instruction, and the affective and cognitive growth of students, researchers have developed hundreds of psychological and educational…
