Intrinsic Religiosity Scale

Abstract

The Intrinsic Religiosity Scale is a widely used psychological instrument designed to measure the degree to which an individual’s religious faith is internalized and serves as the primary organizing principle in their life. This specific version is an adaptation of the original Intrinsic Religious Motivation Scale developed by D.R. Hoge in 1972. The scale assesses the intrinsic dimension of religious orientation, distinguishing genuine, internalized faith from extrinsic motives (such as social belonging or comfort). This adaptation, sometimes referred to as the Faith Devotion Scale, typically utilizes a 10-item format scored using a Likert scale.

Purpose

The primary purpose of the Intrinsic Religiosity Scale is to quantify the depth and internalization of an individual’s religious commitment. It aims to evaluate whether religion is an ultimate goal—a master motive that governs all other aspects of life—or merely a means to an end. Specifically, it helps researchers differentiate individuals whose faith is genuinely lived and integrated into their identity from those who possess extrinsic religiosity, where religion is used instrumentally for social status, security, or comfort.

The scale is instrumental in studies exploring the relationship between the quality of religious belief and various psychological outcomes, including tolerance, prejudice, and mental health. By focusing on the intrinsic dimension, researchers can better understand how internalized faith mediates behaviors and attitudes in complex social contexts.

Construct

The scale measures the psychological construct of Intrinsic Religiosity, a key component within the broader framework of religious orientation established by Gordon Allport. Intrinsic religiosity is defined by the degree to which an individual adheres to their faith for its own sake. For individuals scoring high on this measure, religion is not compartmentalized but rather provides a comprehensive philosophy of life, guiding moral decisions and daily behaviors. The items focus on the pervasiveness of faith and the perceived presence of the Divine in everyday existence.

Conversely, the scale includes items (often reversed-scored) that capture aspects inconsistent with an intrinsic orientation, such as the belief that religious considerations should not influence everyday affairs, or that morality is separate from specific religious beliefs. This inclusion helps ensure the scale effectively isolates the intrinsic dimension from other forms of religious motivation.

Validity

Validation studies of the original Hoge (1972) scale generally support its structure and utility. The instrument demonstrates strong construct validity, correlating significantly with other measures designed to assess deep religious commitment and spiritual maturity. It consistently shows high discriminant validity by exhibiting either weak or negative correlations with measures of extrinsic religiosity, confirming that it measures a distinct motivational orientation.

While the specific 10-item adaptation used by researchers like Hansen and Norenzayan may not have independent, dedicated psychometric studies cited in the source material, its validity rests heavily on the well-established properties of the core items derived from Hoge’s original validated factor structure. The items selected are those known to load highly on the intrinsic factor, ensuring the adaptation maintains fidelity to the intended construct in cross-cultural and social psychology research.

Reliability

The reliability of the Intrinsic Religiosity Scale, particularly the original multi-item version, is well-documented in psychometrics literature. Typically, the scale demonstrates good to excellent internal consistency, with Cronbach’s alpha coefficients commonly falling within the acceptable range of 0.75 to 0.85 across diverse samples. This indicates that the items consistently measure the same underlying dimension.

For the shortened 10-item adaptation, reliability is often maintained due to the high inter-item correlations of the selected items. Researchers utilizing this specific version, such as those studying religious intolerance, rely on the inherent stability of the items to ensure consistent measurement of faith devotion across different population groups.

Factor Analysis

D.R. Hoge initially developed the Intrinsic Religious Motivation Scale as a unidimensional measure intended to capture a single, overarching intrinsic factor. Subsequent confirmatory factor analysis of various intrinsic scales, including adaptations of Hoge’s work, often supports a strong single-factor solution for intrinsic motivation, especially when the focus is on the integrated nature of faith.

However, some research has suggested that the intrinsic construct might be separable into related sub-factors, such as “faith-in-action” (behavioral manifestation) and “faith-as-meaning” (cognitive integration). For the 10-item scale presented here, researchers typically employ it as a unitary measure, calculating a single total score reflecting global intrinsic religious motivation.

Instrument

Test Type: Self-report questionnaire / Attitudinal scale

Format: 10 items administered using a 4-point Likert-type response scale.

Language Available: English (Original items); widely translated and utilized in cross-cultural research.

Population Group: General adult population (Used across various religious and non-religious samples).

Age Group: 18 and older.

Population Details: Used to assess internal motivation among members of diverse religious traditions, including Christians and Buddhists, as demonstrated in the study by Hansen and Norenzayan.

Test Methodology: Respondents rate their agreement with each statement. Scoring involves summing the responses, with items marked with an asterisk (*) being reverse-scored to ensure high scores consistently reflect high intrinsic religiosity.

Permissions & Fee and Test Year

The original Intrinsic Religious Motivation Scale was published in 1972 by D.R. Hoge. The scale is widely used in academic research and is generally considered non-proprietary for scholarly purposes, provided proper citation of the original source (Hoge, 1972) is maintained. The specific 10-item adaptation was utilized in studies published around 2012 (McGowan) and later (Hansen & Norenzayan).
