An investigation of the reliability of the Rosenzweig Picture-Frustration (P-F) Study, Children's Form.
Presents data 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 years, respectively), each group tested twice at an interval of three months. It was found that the retest reliability for all scoring categories (except O-D) were statistically significant (.01 or .05 level). GCR proved stable for the younger group (r = .53) but not for the older group. The difference here may be due to the less comfortable retest conditions prevailing for the older subjects. Reliability by retest was consistently higher than by the less appropriate split-half method, but the latter proved, nevertheless, to be in the main favorable.
