<p>The present article focused on the psychometric evaluation of the Polish version of the Expressions of Spirituality Inventory-Revised (ESI-R), a measure of a five-dimensional model of spirituality that has been studied in multiple cultures. Using a large Polish adult sample (<i>N</i> = 2,002), we examined the reliability and factorial, criterion, and convergent validity of the test. Results provide evidence of satisfactory item- and scale-level reliability for all five ESI-R dimensions. Strong support for the criterion validity and factorial validity of the instrument was also found. Convergent validity as manifested in correlations with conceptually similar measures was supported for four of the five ESI-R dimensions. While there were a couple of points of divergence, findings from the present investigation largely replicate and extend upon results reported in other cultural contexts and provide evidence supporting the possibility that spirituality research may be generalizable across cultures. The paper ends with a discussion of meaning and implications of the findings for theory development, testing, and future research.</p>
