Measuring intrinsic and extrinsic orientation toward religion: amendments for its use among religious and non-religious samples

Amendments to the Age-Universal I-E scale, used to measure intrinsic and extrinsic orientations toward religion, are proposed to facilitate the scales' use among both religious and non-religious samples. The original and revised versions of the intrinsic and extrinsic scales were administered to six adult samples from the U.S.A. (N = 156; N = 144), England (N = 135; N = 149) and Norhern Ireland and Republic of Ireland (N = 189; N = 167). Data show in all six samples the percentage of I-E scales completed was greater for the revised version than the original version. In addition, the revised version of the scales demonstrates more satisfactory reliability estimates than the original version. It is suggested that researchers examining intrinsic and extrinsic orientation towards religion may benefit from using the revised version.
