Description:
The Duke Religion Index (DRI; Koenig, Parkerson, & Meador, 1997) measures organizational (e.g., frequency of religious service attendance), nonorganizational (e.g., frequency of private religious activities, such as prayer, meditation, and Bible study), and intrinsic religiosity (e.g., experiencing the presence of the Divine and religion playing an important role in one’s life).
