Abstract
The Religious Belief Scale (RBS), developed by Carol Martin and Robert C. Nichols in 1962, is a psychometric instrument designed to quantify the characteristics and extent of an individual’s adherence to various religious doctrines and tenets. The scale was initially developed to investigate the personality correlates of religious conviction across populations with differing informational backgrounds.
The RBS is composed of 41 items synthesized from existing measures of religious belief at the time. The core focus areas addressed by the items include belief in the Bible, the efficacy of prayer, the existence of the afterlife, the concept of a personal God, the divinity of Jesus, and the perceived necessity of organized religion and church attendance for maintaining a moral life.

Purpose
The primary purpose of the Religious Belief Scale (RBS) is to provide a standardized method for assessing the characteristics and the overall extent of an individual’s belief system concerning various fundamental religious doctrines. It serves as a tool for researchers exploring the psychological and social variables associated with the acceptance or rejection of traditional religious tenets.
The original development aimed specifically at understanding how religious belief interacts with personality traits and differing levels of religious informational knowledge among respondents, contributing to the field of the psychology of religion.
Construct
The central construct measured by the RBS is Religious Beliefs. This construct is operationalized as a commitment to specific, identifiable doctrines common across many Christian denominations, including fundamental concepts such as the veracity of scripture, the power of intercession (prayer), and the existence of supernatural entities (God, Jesus) and realms (afterlife).
The scale captures a spectrum of conviction regarding these doctrines, positioning the instrument within the broader domain of measuring religious beliefs and practices rather than measuring intrinsic or extrinsic religious orientation.
Validity
The RBS demonstrated robust evidence for criterion validity based on its correlations with established behavioral and demographic indicators of religiosity.
- Positive Correlations: Significant positive correlations (p < 0.01) were observed between high scores on religious belief and several external criteria. These included church attendance (r = 0.62), church membership (r = 0.35), rated parental attitudes toward religion (r = 0.25), and rural background (r = 0.35). Furthermore, a correlation was noted with Bible information (r = 0.29) specifically within low-information groups, suggesting the scale accurately reflects knowledge acquisition linked to belief.
- Negative Correlations: A statistically significant negative correlation (r = -0.16, p < 0.05) was found between religious belief scores and measures of socio-economic status (SES), indicating that higher levels of religious belief, as measured by the RBS, were associated with lower SES in the sampled population.
Reliability
The internal consistency of the Religious Belief Scale was assessed using the Kuder-Richardson method, appropriate for its dichotomous (True/False) response format.
The scale demonstrated high internal consistency, yielding a Kuder-Richardson reliability coefficient of 0.95. This high coefficient, calculated from a sample of 83 participants, suggests that the 41 items are highly homogeneous and measure the same underlying construct of Religious Beliefs effectively.
Factor Analysis
Factor analysis details for the Religious Belief Scale (RBS) were not indicated in the original 1962 publication by Martin and Nichols. While the high reliability suggests unidimensionality or strong shared variance among items, the absence of factor analysis results means the specific underlying dimensions or sub-constructs of religious belief measured by the 41 items remain empirically unexplored within the primary validation study.
