Scale name: Duke University Religion Index (DUREL)
The Duke University Religion Index (DUREL) is a 5-item measure of religious participation. The Index measures three dimensions of religiosity:
1. Organizational Religious Activity (ORA)
2. Nonorganizational Religious Activity (NORA)
3. Intrinsic Religiosity (IR; also called subjective religiosity)
Koenig et al. (1997).
It is a self-report scale. Two questions ask about frequency of activity on a 1 to 6 scale. The two items vary slightly in wording.
Three items reflect religious experience and are rated on a 5-point scale from 1 = Definitely not true to 5 = Definitely true of me
Subscales = 3- see names above
1. How often do you attend church or other religious meetings?
2. How often do you spend time in private religious activities, such as prayer, meditation, or Bible study?
3. In my life, I experience the presence of the Divine (i.e., God)
According to Koenig and Büssing (2010), test-retest reliability was .91 and alphas ranged from .78 to .91.
Koenig and Büssing (2010) reported convergent validity values of r = .71 to .86 with other measures of religiosity. The DUREL has been used in more than 100 studies around the world.
