The <strong>Revised Mystical Experience Questionnaire (MEQ-30)</strong> 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.
</div>
<div class="info-box">
The MEQ-30 was developed by researchers including <strong>Roland Griffiths</strong>, <strong>William Richards</strong>, and colleagues as a refined version of earlier mystical experience scales used in consciousness research and psychedelic science.
</div>
<div class="info-box">
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.
</div>
<div class="info-box">
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.
