Psychometric properties of the short-form CART: Investigating its dimensionality through a Mokken Scale analysis

Rationality is considered an important trait for functioning in modern society, as it thought to be necessary making judgments and decisions. aligns well with ambitions higher education teaching students critical thinkers decision makers. The short-form Comprehensive Assessment of Rational Thinking (CART) might therefore suitable measuring this ability education. Subtest total scores are used interpreted distinguishable units measurement, representing single subconstructs within the concept rationality. In study, we explored whether subtests can indeed unidimensional scales. We assessed subtests’ dimensionality by performing a Mokken scale analysis using performance data 185 on Dutch translation CART. For two subtests, all items formed ordinal scale. three subset seven no items, nor any its current form, then, not CART subtest could meaningfully measures constituent parts rationality, limiting use assessment
