Religious Orientation Scale – ROS
Measures intrinsic (religion as an end in itself) and extrinsic (religion as a means to personal or social ends) religious motivation.
Scale Development & Technical Details
Scale Overview
The Religious Orientation Scale – ROS was developed by Gordon W. Allport & J. M. Ross (1967). It is designed to measure Religious Orientation. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 20 items organized into 2 factors/subscales: Intrinsic, Extrinsic.
| Factor / Subscale | Items | N |
|---|---|---|
| Intrinsic | 1,2,3,4,5,6,7,8,9 | 9 |
| Extrinsic | 10,11,12,13,14,15,16,17,18,19,20 | 11 |
Response Format
Respondents rate each item using a 5-point Likert scale (1 = Strongly Disagree to 5 = Strongly Agree).
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 9 to 55. Interpretation guidelines:
- Intrinsic Scale Score Range (Higher scores indicate stronger intrinsic orientation): 9 – 45
- Extrinsic Scale Score Range (Higher scores indicate stronger extrinsic orientation): 11 – 55
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Intrinsic alpha ~ .85, Extrinsic alpha ~ .70.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
