Spiritual Intelligence Self-Assessment Inventory: Psychometric properties of the Portuguese version of SISRI-24

ABSTRACT

Spiritual intelligence has gained increasing importance as an academic construct in the field of psychology. We present the psychometric properties for the Portuguese adaptation of the Spiritual Intelligence Self-Report Inventory-24, SISRI-24. The exploratory analysis showed a factorial structure different from the original scale, comprising three factors instead of four as in the original version, in which “Transcendental Awareness” was removed. The confirmatory factorial analysis revealed adjustment to a three-factor model for the Portuguese version. The main indexes of adjustment are generally better than the original four-factor version, suggesting the adequacy of this solution for the Portuguese population. The analysis with the convergent measures (SWBQ and MPWQ) provides evidence of the construct’s validity and criterion. The results are promising, allowing us to proceed with the uses of this tool for measuring spiritual intelligence, which may, however, be improved in the future.
