Mystical Experiences Without Psychedelics and How Integration Improves Well-Being in Adults
2026年5月7日 更新者：Baylor University
Mystical Experiences Without Psychedelics: The Nature of Peak Spiritual Experiences and How Integration Leads to Human Flourishing
The goal of this clinical trial is to evaluate whether a guided, non-drug spiritual intervention can facilitate mystical-type experiences and improve well-being in Christian adults.
The main questions it aims to answer are:
- Does the guided spiritual intervention produce measurable mystical experiences?
- Does participation in the intervention and assigned integration program lead to improvements in well-being over time?
Researchers will compare a Christian-based integration program to a structured control integration program to determine whether Christian-based integration leads to greater improvements in well-being.
Participants will:
- Complete baseline questionnaires assessing spiritual experiences, religiosity, and well-being
- Complete one in-person session of the "guided invocation for mystical experience"
- Be randomly assigned to complete either a Christian-based or control integration program for 4 weeks
- Complete follow-up assessments at 1 month and 2 months
調査の概要
詳細な説明
Mystical-type experiences involve acute alterations in consciousness characterized by features such as perceived unity, transcendence of time and space, positive affect, and a sense of encountering ultimate reality. These experiences have been associated with sustained changes in psychological well-being and meaning-making. Most contemporary empirical research has examined such experiences in the context of psychedelic substances; however, non-pharmacological methods for facilitating these experiences remain understudied despite historical precedent and preliminary evidence of feasibility.
This study evaluates a standardized, non-drug intervention, the Guided Invocation for Mystical Experience (GIME), designed to facilitate mystical-type experiences through induction of a non-ordinary state of consciousness. The intervention integrates controlled breathing techniques, guided imagery, and structured verbal suggestion. These components are intended to increase attentional absorption, reduce external sensory input, and promote alterations in perception and self-referential processing consistent with prior models of altered states of consciousness.
The intervention is informed by a conceptual framework in which the occurrence of mystical-type experiences is influenced by three primary factors: (1) induction of a non-ordinary state of consciousness, (2) contextual variables (e.g., environmental setting, expectancy), and (3) structured evocative instructions ("invitation"). The protocol standardizes these elements to enhance reproducibility and reduce variability across participants.
The GIME session is administered in person by a trained practitioner using a manualized procedure. The session includes (1) preparatory instructions and rapport establishment, (2) a structured breathing protocol designed to facilitate physiological and attentional changes, (3) guided imagery and verbal suggestions targeting core dimensions of mystical-type experiences (e.g., unity, sacredness, positive affect), and (4) a brief period of unstructured experiential processing followed by re-alerting procedures. The intervention is designed to be completed within a single session.
Following the intervention, participants are randomized to one of two post-session integration conditions. Integration is conceptualized as an active cognitive and behavioral process through which individuals interpret and incorporate the experience into their existing belief systems and daily functioning. The experimental condition consists of a structured, Christian-oriented integration program including psychoeducational materials, guided reflection exercises, brief recorded audio sessions, and weekly phone calls from the interventionist. The control condition consists of a structurally equivalent program matched for duration, attention, and task engagement but without religious or spiritual content. This comparison allows for evaluation of the specific effects of faith-based integration practices.
The study also examines potential moderating variables influencing both the occurrence and intensity of mystical-type experiences, including baseline religiosity, spirituality, and trait-level factors associated with absorption and responsiveness to altered states of consciousness. These variables are hypothesized to predict variability in experiential outcomes and downstream effects.
This trial is designed to (1) evaluate the feasibility and efficacy of a manualized, non-pharmacological intervention for facilitating mystical-type experiences, (2) characterize the phenomenology of these experiences in a religious sample, and (3) assess the extent to which structured integration practices influence the durability of changes in well-being over time.

実験的：Structured Christian Integration
Participants assigned to the structured Christian integration condition will engage in a 4-week, integration program designed to facilitate reflection on and incorporation of their peak spiritual experience into their existing religious framework.
The intervention includes four modules with psychoeducational materials, structured activities grounded in Christian teachings, and weekly phone calls with the interventionist.
Participants will use a toolkit with weekly writing prompts and recorded audio sessions (14-22 minutes) focused on themes such as revisiting and reflection, awareness and nature, love and connection, and transformation.
Participants will engage with materials regularly (e.g., audio sessions at least four times per week) and submit written responses at the end of each module.
The program is standardized and designed to support ongoing cognitive and emotional processing and integration into daily life and religious practice.
|
Participants will complete a single, in-person Guided Invocation for Mystical Experience (GIME) session conducted by a trained practitioner using a standardized protocol.
The session includes an initial briefing and rapport-building period, followed by a structured breathing exercise (approximately 8 minutes) designed to facilitate a non-ordinary state of consciousness.
Participants then receive guided imagery and verbal suggestions intended to promote relaxation, absorption, and experiential openness.
The practitioner delivers a standardized script targeting features commonly associated with mystical-type experiences (e.g., unity, positive affect, and altered perception of time and space).
The session includes a brief period of silent introspection, followed by re-alerting procedures.
The total session duration is approximately 60 minutes.

Frequency of a Complete Mystical Experience as Assessed by the Mystical Experience Questionnaire
時間枠：Immediately following the in-person guided invocation for mystical experience session
|
Frequency of complete mystical experiences will be assessed using the 30-item Mystical Experience Questionnaire (MEQ30), a validated self-report measure designed to assess key phenomenological features of mystical-type experiences. The MEQ30 includes four empirically derived subscales: Mystical, Positive Mood, Transcendence of Time and Space, and Ineffability. Participants rate the extent to which each item describes their experience. Higher scores reflect greater endorsement of mystical-type features. To determine whether a participant had a complete mystical experience, scores will be calculated for each of the four subscales and expressed as a percentage of the maximum possible score for that subscale. A complete mystical experience is defined as meeting or exceeding 60% of the maximum possible score on all four MEQ30 subscales. The frequency of complete mystical experiences will then be calculated as the proportion of participants who meet this criteria. |

Brief Remote Elkins-Alldredge Test of Hypnotizability
時間枠：1 month post-intervention
|
The Brief Remote Elkins-Alldredge Test of Hypnotizability is a virtual assessment based on the gold standard measure for hypnotizability, the Elkins Hypnotizability Scale (Muñiz et al., in press).
The EHS is a 6 item, therapist-administered scale of hypnotizability.
The six items include arm heaviness or immobilization, arm levitation, imagery involvement or dissociation, positive hallucination of the smell of a rose, positive hallucination of a block, and posthypnotic amnesia.
Scoring is based on the respondent's subjective experience and observable behavioral responses which are summed to obtain a total score (range 0-12) with higher scores indicating greater hypnotizability.
Categorizations of hypnotizability include low (1-4), moderate (5-8), and high (8-12).
Validation studies have demonstrated that the EHS has good internal consistency in an outpatient clinical sample (a = .85;
Elkins, 2014) and in a college student sample (a = .78;
Kekecs et al., 2016).
