Area of Science:

• Psychology
• Cognitive Science
• Psychometrics

Background:

• The Inventory of Personality Organization-Reality Testing Subscale (IPO-RT) and Belief in Science Scale (BIS) are indirect measures of intuitive-experiential and analytical-rational thinking.
• Limited research exists on their factorial structure and person-item functioning.

Purpose of the Study:

• To assess the psychometric properties of the IPO-RT and BIS.
• To evaluate their factorial structure and person-item functioning using confirmatory factor analysis (CFA) and Rasch analysis.

Main Methods:

• Confirmatory factor analysis (CFA) and Rasch analysis were applied to data from 1030 participants.
• Correlation, reliability, unidimensionality, and gender invariance were examined.

Main Results:

• CFA supported a bifactorial model for IPO-RT and a one-factor model for BIS.
• Both scales showed satisfactory reliability and unidimensionality.
• IPO-RT items were more challenging than BIS items, which were easier to endorse.

Conclusions:

• The IPO-RT and BIS are conceptually sound, indirect measures of intuitive-experiential and analytical-rational thinking.
• Future research should evaluate these scales alongside objective tests to understand thinking styles comprehensively.
