Intercorrelations among the Slosson Intelligence Test,the Shipley-Institute of Living Scale,and the Intellectual Efficiency Scale of the California Psychological Inventory

The California Psychological Inventory (CPI), the Slosson Intelligence Test (SIT), and the Shipley-Institute of Living Scale (SILS) were administered to 43 undergraduates enrolled in psychology classes at Austin Peay State University, Clarksville, Tennessee. The Intellectual Efficiency (Ie) scale scores were correlated .52 with the SIT scores and .39 with the SILS scores. The coefficients were significant at the .01 and .05 levels, respectively. The correlation of .49 between SIT and SILS scores was significant at the .01 level. No significance was obtained when the SILS Abstraction scores were correlated with the CPI- Ie or with the SIT scores.
