The Rational-Experiential Inventory-40 (REI-40, Pacini & Epstein, 1999), proposed in the framework of the cognitive-experiential self-theory (CEST) is a widely used instrument for measuring thinking styles. Similar to other dual-processing models, CEST distinguishes between automatic, effortless, rapid (experientiality) and conscious, analytical, effortful, slower (rationality) thinking styles. A short version, REI-10, has already been proposed (Epstein et al., 1996), however, it is based on an outdated REI version and is not compatible with REI-40. There are also modified versions of REI which attempt to capture facets of experientiality, but REI-40 is still used more often than other versions. In the current study we aimed to provide a brief version of REI-40 by employing an Ant Colony Optimisation (ACO) algorithm (Leite et al., 2008; Marcoulides & Drezner, 2009).
We used an existing dataset, collected in the Serbian validation of REI-40, comprising N = 813 students (Purić & Jokić..., 2022), 68% females, Mage = 19.79 (SD = 1.85). We used the ACO procedure to select four items per each REI scale - Rationality and Experientiality, so as to maximize both confirmatory factor analysis model fit, indicated by high Comparative Fit Index (CFI) and low Root Mean Square of Approximation (RMSEA), and high reliability.
The resulting instrument, REI-8 demonstrated good model fit: CFI = .99 and RMSEA = .062 [95% CI .048, .076], as well as reliability - Cronbach’s alpha was .75 for both Rationality and Experientiality, while McDonald’s omega was slightly higher at .78 for both REI-8 scales. The correlations between REI-8 scales and corresponding REI-40 scales were very high, r = .82 and r = .84, for rationality and experientiality, respectively, and the two dimensions were practically uncorrelated r = .04, as the CEST model proposes.
Overall, we have constructed a very brief 8-item version of REI which is both reliable and structurally valid. This instrument could be used in large-scale studies where time is limited.
