Religious Orientation Scale (ROS)
Also known as: Allport-Ross ROS, Religious Orientation Scale, Intrinsic-Extrinsic Religious Orientation Scale, Indiscriminate Proreligious Categorization
The Religious Orientation Scale (ROS), introduced by Gordon Allport and J. Michael Ross in 1967, is the instrument that operationalized Allport's distinction between two motivational stances toward faith. The extrinsic orientation treats religion as a means to other ends — comfort, security, social standing — while the intrinsic orientation treats faith as the master motive that the believer lives by. The ROS measures the two orientations on separate item sets rather than as opposite ends of one continuum, which means a respondent can score high, low, or moderate on each independently. Allport and Ross used this independence to build a fourfold typology, adding the 'indiscriminately proreligious' (high on both) and 'indiscriminately antireligious' (low on both) categories, and showed that orientation, not mere churchgoing, predicted prejudice.
Key highlights
- Captures the motivational quality of religiousness — religion as end versus means — that purely behavioral measures miss.
- Scores intrinsic and extrinsic orientations independently, allowing a respondent to hold both simultaneously.
- Generates the fourfold typology, including the diagnostically important indiscriminately proreligious category.
- Has a strong validity record relating orientation to prejudice and many other psychosocial outcomes.

When to use it
Use the ROS when the research question is not how religious a person is but how they are religious — whether faith functions as an end in itself or as a means to other ends — and when that motivational distinction is expected to relate differently to an outcome such as prejudice, mental health, or prosocial behavior. It is appropriate where respondents are religiously involved enough for the intrinsic-extrinsic contrast to be meaningful, and where you can administer the full item sets and either keep the two scores or build the fourfold typology. It is less suited to nonreligious or marginally religious samples, where extrinsic items behave erratically, and it should be used with awareness of long-standing debates about the extrinsic scale's internal structure and the validity of median-split categorization.
Strengths & limitations
- Captures the motivational quality of religiousness — religion as end versus means — that purely behavioral measures miss.
- Scores intrinsic and extrinsic orientations independently, allowing a respondent to hold both simultaneously.
- Generates the fourfold typology, including the diagnostically important indiscriminately proreligious category.
- Has a strong validity record relating orientation to prejudice and many other psychosocial outcomes.
- The extrinsic subscale is psychometrically weaker than the intrinsic and has been argued to be multidimensional.
- Median-split categorization is sample-dependent and discards information by dichotomizing continuous scores.
- Items presuppose active religious involvement and perform poorly in secular or minimally religious samples.
- The intrinsic-extrinsic dichotomy has been criticized as morally loaded, framing intrinsic faith as 'mature' and extrinsic as inferior.

Frequently asked
What is the difference between intrinsic and extrinsic religious orientation?
Extrinsic religion is religion used as a means to other ends — security, comfort, social belonging, or status — so the self is served by faith. Intrinsic religion is religion lived as the master motive, the framework to which other needs are subordinated, so faith is the end in itself. The ROS measures the two on separate item sets, which is what lets a person score high on both, low on both, or high on one and low on the other, rather than falling somewhere on a single intrinsic-to-extrinsic line.
What are the four categories the ROS produces?
By dichotomizing each subscale, Allport and Ross defined four types: intrinsic (high intrinsic, low extrinsic), extrinsic (high extrinsic, low intrinsic), indiscriminately proreligious (high on both, endorsing religious statements broadly and uncritically), and indiscriminately antireligious (low on both). The indiscriminately proreligious category is the distinctive contribution of the ROS, and in the original study it was associated with the highest levels of prejudice.
Why is the extrinsic subscale considered problematic?
The extrinsic scale has weaker internal consistency than the intrinsic scale and has been argued to contain more than one dimension, for example a personal-comfort facet and a social-benefit facet. It also behaves poorly in samples that are not actively religious, since its items presuppose some religious participation. These issues prompted revised versions of the subscales and continuing debate about whether extrinsic religiousness should be treated as a single construct.
