This paper presents the development and validation of a spiritual leadership measure comprising three sequential stages of scale development. Stage 1 built content validity into the measure through content analysis of interview data, extant literature review, and content expert item analysis. Stage 2 established reliability and preliminary construct validity based on the confirmatory factor analysis of pre-test data. Finally, Stage 3 provided further construct validity through cross-validation in a new sample. The resulting four-item spiritual leadership scale demonstrated robust preliminary psychometric properties. The contributions and implications of the present studies, as well as some future research directions, are discussed in the concluding section.
