Introducing the New Indices of Religious Orientation (NIRO): Conceptualization and measurement

The notion of religious orientation as proposed by Allport and refined by Batson has provided a useful tool for identifying and discussing individual differences in religiosity within Christian and post-Christian contexts. The present paper accepts the conceptual and empirical usefulness of distinctions between the three constructs of intrinsic, extrinsic, and quest religious orientations; reviews the conceptual and empirical strengths, weaknesses, and limitations of existing measures in this field; and proposes three new indices to assess these orientations. The New Indices of Religious Orientation (NIRO) are designed to be of equal length, to give equal empirical weight to three conceptual components within each construct, and to employ direct and accessible language. Data provided from a sample of 517 undergraduate students in Wales demonstrate the satisfactory psychometric properties of these new indices. A clear distinction is made between the appropriate use and the inappropriate misuse of these indices in future research.
