Description

The Humanistic Morality/Liberal Belief Scale (HMLBS) is a psychometric instrument designed to assess individuals’ humanistic moral values and liberal socio-political beliefs. The scale evaluates attitudes toward fundamental concepts such as social justice, human rights, equality, individual freedom, tolerance of diversity, and social responsibility.

Humanistic and liberal beliefs represent important dimensions of an individual’s value system and influence decision-making, moral reasoning, political attitudes, interpersonal behavior, and civic engagement. By measuring these beliefs, the HMLBS provides valuable insight into how personal values shape psychological functioning, social interactions, and attitudes toward contemporary social and political issues.

The instrument is widely applicable in social psychology, political psychology, moral development research, educational sciences, sociology, and cross-cultural studies. It enables researchers and practitioners to examine value systems across different populations and cultural contexts while contributing to the understanding of ethical and ideological orientations.

Questionnaire Structure

The Humanistic Morality/Liberal Belief Scale consists of a series of self-report statements designed to evaluate multiple dimensions of humanistic morality and liberal beliefs.

The questionnaire typically assesses:

  • moral reasoning and social justice,
  • respect for human rights,
  • individual freedom and self-determination,
  • equality of opportunity,
  • social responsibility and solidarity,
  • acceptance of diversity and multiculturalism,
  • support for liberal social and political values.

Participants respond using a Likert-type rating scale, indicating the degree to which they agree or disagree with each statement.

Data Analysis and Applications

Analysis of the HMLBS involves calculating scores for individual dimensions as well as an overall score representing the level of endorsement of humanistic and liberal beliefs.

The instrument is widely used in:

  • social psychology,
  • political psychology,
  • personality research,
  • educational research,
  • moral development studies,
  • sociology,
  • cross-cultural research,
  • evaluation of educational and social intervention programs.

Researchers frequently examine associations between HMLBS scores and variables such as:

  • moral reasoning,
  • empathy,
  • social responsibility,
  • political ideology,
  • tolerance toward diversity,
  • civic engagement,
  • psychological well-being,
  • social trust.

Psychometric evaluation of the HMLBS typically includes internal consistency (Cronbach’s alpha), test–retest reliability, construct validity, convergent and discriminant validity, and Confirmatory Factor Analysis (CFA) to ensure reliable and valid assessment across diverse populations.

Objective

The primary objective of the Humanistic Morality/Liberal Belief Scale is to provide a reliable and standardized assessment of the extent to which individuals endorse humanistic moral principles and liberal social values.

More specifically, the HMLBS aims to:

  • evaluate humanistic moral values,
  • assess beliefs regarding social justice and human rights,
  • examine attitudes toward individual freedom and equality,
  • investigate relationships between moral values, political beliefs, and social behavior,
  • evaluate the effectiveness of educational and social interventions,
  • support research in social psychology, political science, education, and moral development.

Scoring

The HMLBS is typically scored using a 5-point Likert-type response scale, with responses ranging from 1 (Strongly Disagree) to 5 (Strongly Agree).

Individual item scores are summed to produce scores for each dimension as well as an overall scale score.

Depending on the specific version of the instrument, certain items may require reverse scoring before computing the final scores.

Higher scores indicate:

  • stronger endorsement of humanistic moral values,
  • greater support for social justice,
  • stronger commitment to individual freedom,
  • higher respect for human rights,
  • greater acceptance of diversity,
  • stronger social responsibility and civic values.

Interpretation of the results should always follow the official administration and scoring guidelines provided for the specific version of the instrument.

Psychometric Properties

The Humanistic Morality/Liberal Belief Scale (HMLBS) demonstrates satisfactory psychometric properties and has been employed in studies examining moral values, political attitudes, and social beliefs. Validation research has reported good internal consistency, satisfactory test–retest reliability, and evidence of construct validity, with meaningful associations observed between HMLBS scores and measures of moral development, empathy, civic engagement, social responsibility, political ideology, and psychological well-being. These characteristics make the HMLBS a valuable instrument for research in psychology, sociology, education, and political science.
