The Religious Commitment Inventory--10: Development, Refinement, and Validation of a Brief Scale for Research and Counseling.
The authors report the development of the Religious Commitment Inventory-10 (RCI-10), used in 6 studies. Sample sizes were 155, 132, and 150 college students; 240 Christian church-attending married adults; 468 undergraduates including (among others) Buddhists (n = 52), Muslims (n = 12), Hindus (n = 10), and nonreligious (n = 117); and 217 clients and 52 counselors in a secular or 1 of 6 religious counseling agencies. Scores on the RCI-10 had strong estimated internal consistency, 3-week and 5-month test-retest reliability, construct validity, and discriminant validity. Exploratory (Study 1) and confirmatory (Studies 4 and 6) factor analyses identified 2 highly correlated factors, suggesting a 1-factor structure as most parsimonious. Religious commitment predicted response to an imagined robbery (Study 2), marriage (Study 4), and counseling (Study 6).
