Description

The Fundamentalism Scale–Revised (FS-R) is a widely used psychometric instrument designed to assess the extent to which individuals endorse fundamentalist religious beliefs and ideological convictions. The scale measures adherence to absolute religious truths, belief in the inerrancy of sacred texts, and the perception that specific religious doctrines represent the only legitimate framework for understanding reality.

Rather than measuring religiosity or the intensity of religious commitment in general, the FS-R focuses specifically on the cognitive and ideological dimensions of religious fundamentalism, assessing the degree of rigid adherence to dogmatic beliefs and limited acceptance of alternative worldviews.

The instrument is extensively employed in social psychology, the psychology of religion, political psychology, sociology, and cultural studies. It provides researchers with valuable insights into how religious fundamentalism is associated with attitudes, values, decision-making, and social behavior across diverse populations.

Analysis

The Fundamentalism Scale–Revised (FS-R) enables the quantitative assessment of the core characteristics of religious fundamentalism and facilitates the investigation of the cognitive, social, and ideological factors associated with this construct.

The principal dimensions assessed include:

  • Belief in absolute religious truth, reflecting the conviction that religious teachings are unquestionable and universally valid.
  • Commitment to religious tradition, referring to the preservation of traditional religious practices and norms as the only acceptable way of life.
  • Resistance to social and cultural modernization, characterized by the rejection of contemporary values or societal changes perceived as incompatible with religious principles.
  • Religious exclusivism, representing the belief that only one religion possesses the ultimate truth while alternative belief systems are considered incorrect or inferior.

The FS-R is frequently used to investigate the relationship between religious fundamentalism and variables such as:

  • social and political attitudes;
  • prejudice and stereotypes;
  • authoritarianism;
  • social identity;
  • tolerance toward diversity;
  • decision-making processes;
  • psychological adjustment and well-being.

In research settings, FS-R data can be analyzed using descriptive statistics, reliability indices (Cronbach’s α), Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), correlation analyses, group comparisons (independent-samples t-tests, ANOVA, and MANOVA), as well as multivariate regression models and Structural Equation Modeling (SEM), depending on the objectives of the study.

Objective

The primary objective of the Fundamentalism Scale–Revised (FS-R) is to provide a reliable and valid assessment of the degree of religious fundamentalism exhibited by an individual.

More specifically, the instrument aims to:

  • assess adherence to absolute religious beliefs;
  • evaluate acceptance of religious authority as the exclusive source of truth;
  • investigate the relationship between religious fundamentalism and social, political, and cultural attitudes;
  • support research examining the influence of religion on human behavior;
  • contribute to the development of theoretical models concerning religiosity, social identity, and interpersonal relationships.

The FS-R represents an important research instrument for understanding the multidimensional relationship between religious beliefs, cognitive processes, and social behavior.

Scoring

The Fundamentalism Scale–Revised (FS-R) employs a Likert-type response scale, through which respondents indicate the extent to which they agree with statements concerning religious beliefs and values.

In most applications, a five-point Likert scale is used:

1 = Strongly Disagree

2 = Disagree

3 = Neither Agree nor Disagree

4 = Agree

5 = Strongly Agree

The overall score is calculated by summing or averaging individual item responses.

Higher scores indicate stronger adherence to fundamentalist religious beliefs, greater acceptance of absolute religious truth, and a stronger tendency to preserve traditional religious values. Conversely, lower scores reflect more open, flexible, and pluralistic perspectives toward religion and alternative worldviews.

Interpretation of FS-R scores is recommended in conjunction with other psychometric instruments assessing religiosity, spirituality, social attitudes, personal values, and personality characteristics to provide a comprehensive and scientifically grounded understanding of the role of religious beliefs in shaping human behavior.
