At a GlanceAI

Rasch analysis validates the Existential Quest Scale as a comparable measure across demographic and religious groups.

SummaryAI

The study strengthens measurement of existential quest: willingness to engage with existential questions in both religious and secular contexts. Using a large, heterogeneous sample, the authors find that the brief EQS measures one underlying construct and performs consistently across sex, age, and religious affiliation. The analysis also identifies potential improvements to items and response categories, supporting a more precise tool for research on identity, psychological flexibility, and social attitudes.
