The self-reflection and insight scale: applying item response theory to craft an efficient short form

The human ability for self-consciousness—the capacity to reflect on oneself and think about one’s thoughts, experiences, actions—is central understanding personality motivation. present research examined the psychometric properties of Self-reflection Insight Scale (SRIS), a prominent self-report scale measuring individual differences in private self-consciousness. Using tools from Rasch item response theory models, SRIS was evaluated using responses large sample young adults (n = 1192). had many strengths, including essentially zero gender-based differential functioning (DIF), but cluster poor performing items identified based misfit, high local dependence, low difficulty discrimination. Based IRT analyses, concise 12-item scale, evenly balanced between self-reflection insight, crafted. short showed strong dimensionality, reliability, fit, independence as well no gender DIF. Taken together, strengths support its popularity, form will be useful applied contexts where an efficient, version is needed.
