Investigating the Relationship Between JCCES and RIAS Verbal Scale: A Principal Component Analysis Approach

Abstract This study examined the relationship between the Jouve Cerebrals Crystallized Educational Scale (JCCES) and the Reynolds Intellectual Assessment (RIAS) Verbal Scale using Principal Component Analysis (PCA). The PCA revealed a strong relationship between JCCES and the RIAS Verbal Scale, supporting the hypothesis that there is a common underlying construct …

Analyzing the Item Structure of the General Knowledge Subtest in the Jouve-Cerebrals Crystallized Educational Scale (JCCES) Using Multidimensional Scaling

Abstract The purpose of this study was to analyze the item structure of the General Knowledge Subtest in the Jouve Cerebrals Crystallized Educational Scale (JCCES) using multidimensional scaling (MDS) analyses. The JCCES was developed as a more efficient assessment of cognitive abilities by implementing a stopping rule based on consecutive …
