Revised Mystical Experience Questionnaire (MEQ-30)

Background

The Revised Mystical Experience Questionnaire (MEQ-30) is a widely used self-report instrument designed to measure mystical-type experiences, altered states of consciousness, feelings of unity, transcendence, sacredness, and deeply meaningful spiritual experiences.
The MEQ-30 was developed by researchers including Roland Griffiths, William Richards, and colleagues as a refined version of earlier mystical experience scales used in consciousness research and psychedelic science.
The questionnaire evaluates experiences related to unity, transcendence of time and space, sacredness, intuitive insight, positive emotional states, ineffability, and encounters with perceived ultimate reality.
Research studies have demonstrated strong reliability and validity for the MEQ-30 across psychedelic research, meditation studies, spirituality research, altered states of consciousness studies, and transpersonal psychology.

Psychological Domains Measured

Mystical Unity
Measures experiences of oneness, unity, interconnectedness, ego dissolution, and merging with a greater whole.
Transcendence of Time and Space
Measures altered awareness of time, timelessness, spacelessness, infinity, and transcendence of ordinary reality.
Sacredness and Spirituality
Measures feelings of sacredness, holiness, reverence, spiritual elevation, and connection with ultimate reality.
Positive Mood and Emotional Elevation
Measures peace, joy, ecstasy, awe, tenderness, tranquility, and emotionally uplifting experiences.
Insightfulness and Noetic Quality
Measures intuitive insight, perceived profound knowledge, certainty of truth, and meaningful realization.
Ineffability
Measures difficulty describing the experience in words or communicating the experience to others.
The MEQ-30 is commonly used in consciousness research, meditation studies, psychedelic science, transpersonal psychology, spirituality research, and altered-state studies. The questionnaire is intended for research and educational purposes and should not be interpreted as a diagnostic instrument.

Procedure

This questionnaire is designed to evaluate subjective mystical-type experiences, altered states of consciousness, spiritual experiences, and emotionally transformative experiences.

Participants select the response option that best reflects the intensity or degree to which each experience occurred during a meaningful altered-state, spiritual, meditative, or consciousness-related experience.

The assessment focuses on unity experiences, sacredness, transcendence, intuitive insight, emotional elevation, timelessness, and ineffability.

Participation

This assessment is intended for educational, screening, and research purposes only.

Results should not be interpreted as proof of spiritual authority, supernatural experiences, or clinical diagnosis.

Experiences measured by the MEQ-30 may arise in various contexts including meditation, religious practice, contemplative states, psychedelic experiences, peak experiences, and emotionally transformative events.

Scoring & Interpretation

Responses are scored according to the intensity and frequency of mystical-type experiences and altered states of consciousness.

Higher scores generally indicate stronger experiences of unity, transcendence, sacredness, emotional elevation, intuitive insight, and mystical consciousness.

The MEQ-30 measures six primary experiential dimensions:
- Mystical Unity
- Transcendence of Time and Space
- Sacredness and Spirituality
- Positive Mood and Emotional Elevation
- Insightfulness and Noetic Quality
- Ineffability
