Psychometric examination of a Brazilian adaptation of the Expressions of Spirituality Inventory – Revised

Abstract

Using a sample of 493 adults, the present investigation examined the psychometric properties of a Brazilian adaptation of the Expressions of Spirituality Inventory-Revised (ESI-R; MacDonald 2000a), a measure of an empirically derived five dimensional model of spirituality which has been shown to have some promise for cross-cultural research. Reliability analysis indicated that the ESI-R dimensions produced satisfactory inter-item consistency coefficients. Exploratory factor analysis provided evidence generally supportive of the replicability of the five dimensions. Confirmatory factor analysis testing two competing factor models (four versus five factor) provided some support for both models. However, the five factor model emerged superior. Support for both convergent and discriminant validity of the ESI-R dimensions was also obtained. Overall, the findings of this study are consistent with those seen with samples from other cultures and suggest that the ESI-R holds promise for use in spirituality research in Brazil.
