Psychometric Evaluation of the Italian Adaptation of the Test of Inferential and Creative Thinking

Abstract

This article describes the psychometric properties of the Italian adaptation of the Analyse des Schlussfolgernden und Kreativen Denkens (ASK; Test of Inferential and Creative Thinking) for measuring inferential and creative thinking. The study aimed to (a) supply evidence for the factorial structure of the instrument, (b) describe its reliability in terms of internal consistency, and (c) explore its convergent and discriminant validity. The examinees were 284 high school students and adult graduates. Both exploratory and confirmatory factor analyses were used to examine the dimensional structure. The 2-factor model provided an acceptable fit for the empirical data. As expected, stronger correlations were found among the subscales within the same construct domains compared to correlations among the subscales from the different construct domains. The psychometric qualities of the ASK appeared fairly good, thereby suggesting that it might be helpful in several application fields, including academic and professional guidance, human resource selections, and job placement.
