Recent (1962–1964) Psychiatric-Patient Validation Norms for the Shipley-Institute of Living Scale
The Shipley-Institute of Living Scale was administered to 886 mental patients who were newly admitted to a state hospital. Frequency distributions, frequency percentages, means, and standard deviations for the four Shipley Scale scores (Vocabulary, Abstraction, Total, and Conceptual Quotient) were computed. No sex differences were observed. The mean Conceptual Quotient found was similar to the median values observed 25 yr. ago in the original validation of the Shipley Scale.
