Factor analyses of traditional and age-universal measures of intrinsic and extrinsic religion have identified two subcategories of extrinsicness, suggesting the original scales need revision. In this study, confirmatory multiple group factor analyses confirmed this suspicion, identifying extrinsic items concerned with social relationships ("Es") and with personal benefits ("Ep"). The analyses resulted in a revised intrinsic scale which is now partially counterbalanced for acquiescence, an Es scale, an Ep scale, and three single items which may also be used for measuring these constructs. These scales, labeled I/E-R, have reliabilities equal to or better than those of the original scales.
