Intense Meditation-Related Experiences (IMREs) and Perceived Impacts on Self and Worldview: An Interpretative Phenomenological Analysis

Mindfulness May 19, 2026 Tim Wood, Merle Kock, Nicholas T. van Dam et al.

Intense meditation-related experiences (IMREs) can suddenly alter a person's sense of self, worldview, and emotions, but their meaning often shifts as meditators reflect and interpret them over time within their social and cultural context. Through in-depth interviews with 13 participants, four themes emerged: watching the self and world transform; emotional explosions leading to insight; deciding whether to share the experience or remain silent; and developing new perspectives and agency. Most participants found that the meaning of their IMREs became clearer through conversation with others, using concepts from science and meditation traditions. These experiences were transformative, offering new ways of perceiving and acting in the world.

Contemplative practices serve as complementary mental health strategies in nationally representative samples from Australia and New Zealand

Scientific Reports May 19, 2026 Karin Matko, Cate Bailey, Julieta Galante et al.

Seventy percent of adults in Australia and New Zealand engaged in contemplative practices such as meditation, yoga, or breathing techniques in the past year, most commonly meditation (31%). Practitioners reported higher psychological distress and greater use of mental healthcare than non-practitioners. After adjusting for sociodemographic differences, the association with distress disappeared for yoga and relaxation practitioners but remained for breathing techniques, which were linked to increased distress in all models. Among those with unmet healthcare needs, meditators and relaxation practitioners reported less distress than non-practitioners with unmet needs. The findings suggest contemplative practices may serve as complements to mental healthcare, but their complex relationships with mental health require further study.

A cross-sectional survey on depersonalization/derealization and meditation-induced alterations of the self.

Scientific Reports May 8, 2026 Erola Pons, Julieta Galante, Nicholas T. van Dam et al.

Depersonalization and derealization (DPDR) involve feeling detached from one's body, thoughts, or emotions, typically triggered by trauma, stress, or drugs and causing high distress. Similar experiences arise during meditation, where they are often described as positive and meaningful. This cross-sectional study compared DPDR-like states triggered by meditation (60 participants) versus other triggers (61 participants). The meditation-triggered group rated their experiences as substantially more positive, though most participants in both groups described them as mixed. Meditation-induced DPDR occurred across types and experience levels. These experiences are phenomenologically similar but more welcome, pleasant, and spiritually meaningful than those from trauma or cannabis, though distress is not uncommon. Contemplative approaches may inform clinical support for DPDR, and guidance within meditation settings is needed.

Quality of Life, Healthcare Use and Cost of Practice From a Nationally-Representative Australian Survey to Inform Future Economic Evaluations of Contemplative Practices

Mindfulness February 25, 2026 Cate Bailey, Nicholas T. van Dam, Jonathan N. Davies et al.

A nationally representative Australian survey compared quality of life, health service use, and costs among meditators, other contemplative practitioners, and non-practitioners. Unadjusted quality-of-life scores were higher for non-practitioners, and this difference persisted after accounting for demographics but disappeared when mental health service use was included. Unmet mental-health service need was highest among meditators (13.9%) versus non-practitioners (2.4%). The average annual cost of contemplative practice was $1,281 per person. The findings provide preliminary data for future economic evaluations of contemplative practices.

Engagement With Meditation Apps: Cross-Sectional Survey of Use and Associations.

Journal of Medical Internet Research February 2, 2026 Julia Adams, Jonathan N. Davies, Prai Wattanatakulchat et al.

Most people who download meditation apps use them very little. In a survey of 536 recent users across five English-speaking countries, those who were more educated, more open to new experiences, and who held stronger beliefs that meditation apps would help them were more likely to engage regularly. Readiness to change, expectations for sleep and thriving, and perceived app quality and appeal were also linked to greater use. Age and higher education were among the strongest predictors of engagement. The findings suggest that user characteristics and attitudes toward the app matter more than mental health symptoms for determining how much someone uses a meditation app.

Introducing interdisciplinary contemplative pedagogy: a case study of ‘ The Art and Science of Meditation ’

Pedagogy Culture and Society December 8, 2025 Christopher T. Mccaw, Haisu Sun, Julieta Galante et al.

A model for applying contemplative pedagogy in higher education emphasizes rich contextualization and interdisciplinarity. The framework places embodied contemplative practices within concentric layers of context, drawing from multiple disciplinary perspectives. It addresses challenges educators face in contemporary universities, using cosmopolitanism to navigate epistemological, cultural, and practical diversity. The course 'The Art and Science of Meditation' illustrates this approach.

Contemplative Practices as Complementary Mental Health Strategies: Insights from a Nationally Representative Sample in Australia and New Zealand

October 20, 2025 Karin Matko, Cate Bailey, Julieta Galante et al. preprint

A nationally representative survey of 2,640 Australians and New Zealanders found that 70% had engaged in contemplative practices over the past year, most commonly meditation, relaxation, breathing techniques, and yoga. Users of these practices reported higher psychological distress and mental healthcare use than non-practitioners. After adjusting for socio-demographic differences, the association with distress disappeared for yoga and relaxation practitioners; for meditators it disappeared when accounting for mental healthcare use. Breathing practice remained linked to increased distress across all models. However, meditators and relaxation practitioners with unmet healthcare needs reported less distress than non-practitioners with unmet needs. The practices may play a complementary or alternative role in managing mental health.

Quality-Of-Life, Healthcare Use and Cost of Practice from a Nationally-Representative Australian Survey to inform future economic evaluations of Contemplative practices

September 16, 2025 Cate Bailey, Nicholas T. van Dam, Jonathan N. Davies et al. preprint

A nationally representative Australian survey of 2,065 people found that meditators and other contemplative practitioners had lower unadjusted quality-of-life than non-practitioners, a difference that persisted after accounting for demographics but disappeared when mental health service use was considered. Unmet mental-health service need was highest among meditators (13.9%) versus non-practitioners (2.4%), and 8.9% of the overall sample had unmet need. The average annual cost of contemplative practices was $1,281 per person. The findings provide preliminary data for future cost-effectiveness evaluations of contemplative practices, with the EQ-HWB-9 index performing well as an outcome measure.

Examining the Dose-Response Effects of Mindfulness Meditation Interventions on Well-Being: Protocol for a Randomized Controlled Trial.

JMIR Research Protocols July 29, 2025 Nicholas Bowles, Alexander Burger, Jonathan N. Davies et al.

A proposed randomized controlled trial will test whether longer daily mindfulness meditation sessions produce greater improvements in well-being. Healthy adults aged 18–65 will be assigned to 4-week online courses with 10, 20, or 30 minutes of daily practice, or a 4-minute control condition. The primary outcome is psychological well-being, measured at baseline, midintervention, postintervention, and one-month follow-up. The trial aims to enroll at least 688 participants; as of end of 2024, 70 eligible participants were enrolled. Results are expected by March 2026.

“Exploding into the Universe”: Exploring intense meditation-related experiences (IMREs) and perceived impacts on the sense of self

July 25, 2025 Tom Wood, Merle Kock, Nicholas T. van Dam et al. preprint

Intense meditation-related experiences (IMREs) can alter the sense of self, worldview, and emotions, impacting daily life. Through in-depth interviews with thirteen meditators, four themes emerged: watching the self and world transform; emotional explosions leading to insight; gaining new perspectives and agency; and challenges in talking about the experience. Meditators used concepts from science and meditative traditions to make sense of IMREs, which were profound transformative experiences that changed how they perceived and acted in the world. The meaning of these experiences was immediately clear for some but clarified over time for most.

Meditation experiences through a developmental lens: Does the “Stages of Insight”, a Buddhist model of meditative progression, apply to contemporary meditators?

May 27, 2025 Prai Wattanatakulchat, Julieta Galante, Timothy Wood et al. preprint

Unwanted meditation-related experiences are common and alternate with positive ones, but predicting them is difficult because they have been studied as isolated events. This survey of 886 U.S. meditators tested whether a modern interpretation of the Stages of Insight (SoI), a Buddhist model of meditative progression, fits contemporary meditators. Only four of the eight stages could be assessed. The pattern of item endorsement predicted the number of stages reached better than chance, but early stages were not more frequently endorsed than later ones, and more meditation experience did not predict classification into later stages. The findings provide no clear evidence that the SoI model applies across contexts and traditions, but show that traditional models can guide research on meditation experiences as developmental processes.

The feasibility and acceptability of an online mindfulness-based stress reduction program for chronic musculoskeletal pain: protocol for a pilot randomised controlled trial.

Pilot and Feasibility Studies March 15, 2025 Anita B Amorim, Trudy Rebbeck, Nicholas T. van Dam et al.

A pilot randomized controlled trial will test the feasibility and acceptability of an online mindfulness-based stress reduction (MBSR) program for people with chronic musculoskeletal pain who are on waitlists for multidisciplinary pain clinics in Australia's public healthcare system. Thirty-two participants from two clinics in Sydney will be randomly assigned to either the online MBSR group or usual care. The study will assess feasibility, patient-reported outcomes, adherence to mindfulness practice, and adverse events using validated questionnaires, along with qualitative interviews to explore participants' experiences. Results will guide the design of larger future trials.

Examining the Dose-Response Effects of Mindfulness Meditation Interventions on Well-Being: Protocol for a Randomized Controlled Trial (Preprint)

February 17, 2025 Nicholas Bowles, A. Bürger, Jonathan N. Davies et al.

A planned online mindfulness course for healthy adults aged 18–65 years will test whether longer daily meditation practice (10, 20, or 30 minutes) produces greater improvements in well-being and other psychological outcomes than a short control practice (4 minutes). The study aims to enroll at least 688 participants, but recruitment has been slow and affected by fraudulent entries; by the end of 2024 only 70 eligible participants had enrolled. The trial will measure well-being, distress, anxiety, depression, and other factors at several time points, with results expected by March 2026.

Introducing interdisciplinary contemplative pedagogy: A case study of “The Art and Science of Meditation”

February 11, 2025 Christopher T. Mccaw, Julieta Galante, Cullan Joyce et al.

A conceptual framework is presented for applying contemplative pedagogy in higher education, emphasizing rich contextualization and interdisciplinarity. The model places embodied contemplative activities within concentric layers of socio-cultural, political, religious, ethical, and material context. Cosmopolitanism is introduced to address epistemological, cultural, and practical diversity encountered by educators and students. The framework is illustrated through a case study of an undergraduate subject, The Art and Science of Meditation, designed by the authors.

Value Signals Guiding Choices for Cannabis Versus Non-Drug Rewards in Regular Cannabis Users

March 15, 2023 Will Lawn, Xuejun Hao, Anna B. Konova et al. preprint

Near-daily cannabis users show normal neural value encoding for cannabis but disrupted encoding for non-drug rewards like snacks, even when their actual choices are equivalent. The study used a neuroeconomic framework to measure brain activity while participants chose between varying amounts of cannabis or snacks and money. Value signals for cannabis appeared in brain regions typically involved in reward processing (ventromedial prefrontal cortex, ventral striatum, dorsal posterior cingulate cortex), but these signals were weaker or absent for snacks. The findings support the idea that problematic substance use involves dysregulated neural valuation of non-drug rewards.

The Effectiveness and Exploratory Cost-Effectiveness of Regular Meditation for Improving Quality of Life: Protocol for a Prospective Longitudinal Cohort Study.

JMIR Research Protocols July 17, 2026 Lillian Ofori Ward, Cate Bailey, Prai Wattanatakulchat et al.

A protocol for a prospective longitudinal cohort study will follow 600 beginner meditators in Australia, New Zealand, the United States, and the United Kingdom over one year to investigate whether regular meditation practice improves quality of life and mental well-being. The study will compare effects between secular and spiritual practitioners, assess cost-effectiveness in terms of quality of life, and track the incidence and functional impact of any adverse effects. Participants report practice frequency and duration weekly via an app, with monthly sampling of quality of life, well-being, practice characteristics, costs, and adverse effects. Data collection began in October 2025; results are expected in January 2028.

Focused attention meditation in healthy adults: A systematic review and meta-analysis of cross-sectional functional MRI studies.

Neuroscience and Biobehavioral Reviews October 1, 2022 Saampras Ganesan, Emillie Beyer, Bradford A. Moffat et al.

Focused attention meditation consistently engages three key functional brain networks: the Default-mode, Salience, and Executive Control networks. A quantitative meta-analysis of 10 functional MRI studies (200 participants) showed that meditation expertise, mindfulness levels, and attentional skills influence the magnitude, but not the regional extent, of activation and functional connectivity in these networks. A unified neurocognitive brain-network model of focused attention meditation is proposed.

Neuroscience of embodied reflection: somatic/mindbody/contemplative practices, health, and transformative learning

October 7, 2020 Noémie Le Pertel, Jonathan Fisher, Nicholas T. van Dam

Transformative learning, which uses reflection to produce deep change in adult learners, can become embodied in neurobiological and cardiovascular systems, requiring health of both body and mind. Contemplative and embodied reflective practices are technologies that support reintegrating body, brain, and mind, thereby fostering transformative learning and sustainable change.

Reiterated Concerns and Further Challenges for Mindfulness and Meditation Research: A Reply to Davidson and Dahl.

Perspectives on psychological science : a journal of the Association for Psychological Science January 1, 2018 Nicholas T. van Dam, Marieke K. van Vugt, David R. Vago et al.

The authors reply to a commentary by Davidson and Dahl, agreeing with many suggestions but emphasizing that their original concerns remain especially relevant to mindfulness and meditation research. They highlight the vulnerability of this relatively young field compared to more mature scientific disciplines, discuss special characteristics of research participants, and stress the serious consequences of adverse experiences that a significant subset of individuals suffer during mindfulness and other contemplative practices. They also scrutinize common applications of mindfulness and meditation to illness and introduce caveats regarding mobile technologies for guiding contemplative practices.
