Two-Week Test-Retest Reliability of the Duke Religion Index

Abstract

The present study investigated 2-wk. test-retest reliability of the Duke Religion Index, a 5-item self-report questionnaire that assesses organizational, nonorganizational, and intrinsic religiosity. The sample consisted of 20 undergraduate college students (11 women) whose mean age was 24.7 yr. (SD=5.0 yr.). Findings supported the 2-wk. test-retest reliability of the Duke Religion Index with an intraclass correlation coefficient of .91.
