Here's the abstract (subject to change):
The aim of this research is to examine both the validity and the reliability of scores yielded by the Jouve-Cerebrals Test of Induction (JCTI). The main analysis was conducted on the data gathered from 1,020 examinees, most of them having taken voluntarily the JCTI as an online assessment. In this study, construct validity, internal consistency and item analysis of the scale were examined. As a result of factor analysis for construct validity, the JCTI showed to be very highly loaded on the general ability factor (.88) latently linking it with the subscales of the Scholastic Assessment Test-Recentered (SAT-I) and proved to be the most loaded in inductive reasoning (.96). The reliability coefficients as calculated with different methods and on different groups of test-takers showed on a general point of view a very satisfactory level up to .96. Analyses also demonstrated that the correlations with other measures of cognitive ability were within the expectations and higher magnitudes of Pearson’s coefficient were observed with nonverbal tasks. As an example, the JCTI Reasoning Index (RIX) and the Performance IQ of the Wechsler Adult Intelligence Scale (WAIS) were correlated at .80. The mean obtained with JCTI RIX did not significantly differ from others yielded by nonverbal measurements. Furthermore, the JCTI RIX was seen to be very closely related to the mathematical scale of the SAT-I at .84. Significant correlations were also observed with general and crystallized intelligence measures. According to these findings the JCTI RIX can be regarded as a valid and reliable measure that could be used in the field of education and psychology.
