The spiritual experience index: A measure of spiritual maturity

Abstract

The Spiritual Experience Index was developed to measure spiritual maturity in persons of diverse religious and spiritual beliefs. The scale was constructed from a developmental rather than a multidimensional conceptualization of faith. Initial findings from a religiously heterogeneous college sample indicated good reliability for the SEI and supported its use as a unidimensional measure. Higher scores on the SEI were significantly related to lower dogmatism and intolerance of ambiguity. The SEI was also moderately related to higher religious participation and positively correlated with intrinsicness and quest. However, compared with the intrinsic and quest scales, the SEI emerged as the strongest indicator of adaptive spiritual functioning. Directions for future research are suggested.
