Strategies for resolving challenging psychedelic experiences: insights from a mixed-methods study

Psychedelic compounds are under renewed scientific scrutiny for potential therapeutic benefit, yet the role of challenging or difficult experiences within psychedelic sessions remains incompletely understood. Earlier research has emphasised the importance of peak or mystical experiences for therapeutic gains, but there is growing recognition that non-peak elements—such as intense negative emotions, physical discomfort, or confronting past trauma—can also contribute to positive outcomes in some cases, while sometimes producing prolonged difficulties. Contemporary treatment protocols and user guidelines commonly advocate acceptance and 'surrender' during difficult moments, yet the empirical basis for which coping strategies best resolve challenging psychedelic experiences is limited. Wood and colleagues sought to fill this gap using a mixed-methods design. They first used qualitative analysis of retreat participants' written accounts to identify coping strategies and inform the creation of a new measure, the Responses to Challenging Psychedelic Experiences Inventory (ReCiPE). They then administered the ReCiPE in a large online sample to explore its factor structure and to examine associations among types of challenging experiences (measured by the Challenging Experience Questionnaire, CEQ), response strategies (ReCiPE factors), and emotional breakthrough (measured by the Emotional Breakthrough Inventory, EBI). The aim was to characterise common strategies, test whether 'acceptance' strategies predict emotional breakthrough, and explore whether different challenge types call for different responses.

All procedures received institutional ethical approval and adhered to the Declaration of Helsinki. Eligibility across studies required participants to be aged 18 or older, English proficient, and to have prior experience with classic psychedelics. Electronic informed consent was obtained online. Neither study was pre-registered. Both Study 1 (qualitative) and Study 2 (survey) were conducted via Qualtrics. Study 1 recruited attendees of psilocybin retreats at four centres in the Netherlands and Mexico who had consented to be contacted for research and who reported having experienced significant personal transformation alongside distress during ceremonies. The qualitative survey collected demographics and detailed open-ended narratives about the nature of challenging episodes, how participants responded, how the episodes resolved, and the meaning derived. Two researchers independently coded the narratives using an inductive thematic analysis approach (Braun and Clarke framework) in NVivo; codes were iteratively refined and grouped into themes reflecting coping strategies. Involuntary reactions intrinsic to the experience (e.g. fight-flight) were excluded from the coping strategy coding. Study 2 recruited a larger, online convenience sample of individuals with prior experience of classic psychedelics (psilocybin, ayahuasca, LSD, DMT, mescaline); purely non-classic experiences (e.g. MDMA-only, ketamine-only) were excluded unless combined with classic psychedelics. Measures included demographic/contextual items, the 26-item Challenging Experience Questionnaire (CEQ; 6-point Likert, seven subscales), the 6-item Emotional Breakthrough Inventory (EBI; visual analogue 0–100), and the newly developed 26-item ReCiPE. ReCiPE items derived from Study 1 themes and literature review asked whether participants had not tried a strategy, tried it but found it unhelpful, tried and found it somewhat helpful, or tried and found it substantially helpful. Because the original labels were asymmetric and not strictly ordinal, responses were transformed into a binary coding for exploratory psychometrics (0 = did not try or tried and not helpful; 1 = tried and somewhat/substantially helpful). ReCiPE 'scores' used in analyses therefore represent counts of strategies judged helpful. Statistical analyses used Mplus, Python and JASP with α = 0.05. Descriptive statistics summarised sample characteristics and strategy frequencies. Exploratory factor analysis (EFA) of the binary ReCiPE items used WLSMV estimation on a tetrachoric correlation matrix with oblique (Geomin) rotation; two-, three- and four-factor solutions were compared using fit indices (RMSEA, CFI, TLI), scree plots, theoretical interpretability, and cross-loading criteria. Internal consistency was evaluated using Cronbach's alpha and KR-20 where appropriate. Pearson correlations assessed relationships among CEQ subscales, ReCiPE factors, and EBI average. Predictors that correlated with EBI were entered into a multiple linear regression to evaluate contributions to emotional breakthrough; regression assumptions (linearity, normality, homoscedasticity, independence) and multicollinearity were assessed using standard diagnostics (residual plots, Durbin-Watson, Breusch-Pagan, VIF/Tolerance). The adjusted R2, unstandardised (B) and standardised (β) coefficients, t-tests and 95% confidence intervals were reported.

Study 1: Sixteen retreat attendees (8 Netherlands, 8 Mexico) completed the qualitative survey. Retreats lasted 3–7 days with up to three ceremonies; median time since attendance was 6 months and mean age was 45 years. Most participants were highly educated. Thematic analysis identified four principal themes of responses to challenging psychedelic experiences: Inner Responses (acceptance, observing, self-reassurance, interrogating/challenging the content, meaning-making), Embodied Practice and Engagement with the Environment (intentional breathing, movement, sensory contact, seeking sleep), Interpersonal Responses (social avoidance, asking for help, disclosure/confession), and Facilitator Responses (physical touch, reassurance, introducing supportive interventions). Illustrative participant excerpts described moving or swaying to manage nausea, going outside to ground oneself, asking facilitators for help during panic, and experiencing relief through disclosure and embodied connection. Study 2: Of 869 survey completers, 555 (64.24%) reported experiencing some form of challenge; 529 (95.31% of those) provided data used in subsequent analyses. The sample was gender-balanced (243 male, 256 female, 30 non-binary/other) with a mean age of 37.71 years (SD = 10.88). Item-level ReCiPE frequencies showed that acceptance/observational strategies were commonly attempted and rated helpful: "I tried to let go, accept or surrender to the experience" was reported as helpful by 84.5% of participants, "I tried to observe my mind and not fight it" by 77.3%, and "I tried closing my eyes, lying or sitting down" by 73.9%. Less commonly helpful strategies included directing anger/aggression at the experience (9.4%), trying to fall asleep (9.7%), assertively telling the experience to 'stop' (10.6%), and taking another drug or alcohol (12.1%). On average participants endorsed 11.25 ± 4.78 strategies as helpful (mode = 10). EFA of the binary-coded 26 ReCiPE items favoured a three-factor solution on theoretical and empirical grounds (RMSEA < 0.05; CFI/TLI > 0.9), with fewer problematic cross-loadings than competing models. The three factors were interpreted as: Acceptance and Reappraisal (Factor 1; 11 items), Sensory Regulation and Physical Interaction (Factor 2; 10 items), and Social Support and Disclosure (Factor 3; 5 items). Factors 1 and 2 were modestly correlated (r = 0.330); other pairwise correlations were weaker. Three items failed to load strongly on any factor (assertively telling the experience to stop, trying to fall asleep, taking another drug/alcohol) and were among the least-used strategies. Internal consistency for the full ReCiPE was α = 0.801; subscale alphas were acceptable (Factor 1 α ≈ 0.726, Factor 2 α ≈ 0.731, Factor 3 α ≈ 0.786) and removal of low-loading items had negligible effect on reliability. Correlation analyses indicated that CEQ subscales Fear, Grief, Physical Distress, and Death were significantly associated with EBI average, whereas Insanity, Isolation, and Paranoia were not. All three ReCiPE factors correlated positively with EBI average, implying that reporting a greater number of perceived-helpful strategies was associated with higher emotional breakthrough scores. A specific association noted was that Grief-related challenges correlated positively with the use of Acceptance/Reappraisal strategies (r = 0.19, p < 0.001), while Fear was associated with using fewer helpful Acceptance/Reappraisal strategies. Multiple regression including CEQ factors (Fear, Grief, Physical Distress, Death) and ReCiPE factors (Acceptance/Reappraisal, Sensory Regulation/Physical Interaction, Social Support/Disclosure) significantly predicted emotional breakthrough (F(7, 519) = 50.93, p < 0.001), explaining 40% of variance (adjusted R2 = 0.40). Diagnostic checks indicated acceptable linearity, normality, homoscedasticity and no problematic autocorrelation (Durbin-Watson = 1.96); multicollinearity was low (Tolerance 0.59–0.87; VIF 1.15–1.70). Significant predictors included Fear (standardised β = -0.24, 95% CI [-0.30, -0.14], t = -5.50, p < 0.001), Grief (β = 0.37, 95% CI [0.28, 0.42], t = 9.78, p < 0.001), Death (β = 0.17, 95% CI [0.07, 0.19], t = 4.45, p < 0.001), Acceptance and Reappraisal (β = 0.33, 95% CI [0.16, 0.26], t = 8.29, p < 0.001) and Social Support and Disclosure (β = 0.07, 95% CI [0.00, 0.12], t = 2.05, p = 0.041). The extracted text reports unstandardised interpretations such as a one-unit increase in Grief corresponding to a 0.37-unit increase in emotional breakthrough and a one-unit increase in Fear corresponding to a 0.24-unit decrease. Note: some reported confidence intervals in the extraction appear internally inconsistent with the stated β values (for example, the CI for Acceptance and Reappraisal does not encompass the reported β), which may reflect extraction artefacts.

Wood and colleagues interpret their findings as providing preliminary empirical support for a diversified taxonomy of coping strategies for challenging psychedelic experiences, and for the potential importance of acceptance-based and interpersonal strategies in facilitating emotional breakthrough. The qualitative phase identified a broad repertoire of intra-personal, embodied, social, and facilitator-mediated responses, which the ReCiPE captured and that EFA reduced to three coherent factors: Acceptance and Reappraisal, Sensory Regulation and Physical Interaction, and Social Support and Disclosure. Descriptively, acceptance/observational strategies were commonly used and rated as helpful by many participants. The investigators highlight the differential relationships between types of challenges and outcomes: grief- and death-related experiences were positively associated with emotional breakthrough, whereas fear-related challenges were negatively associated. They suggest that fear may induce avoidance and impair engagement with acceptance-based strategies, thereby inhibiting breakthrough, while grief and death experiences may prompt adaptive cognitive processing and openness to social support. From a clinical standpoint, the authors propose that integrating acceptance- and reappraisal-focused training—such as Acceptance and Commitment Therapy (ACT), mindfulness, and cognitive reappraisal—into preparation for psychedelic therapy could mitigate fear's detrimental effects and enhance therapeutic processing. They also argue that therapists should be familiar with a wide repertoire of strategies given individual and contextual variability in what proves helpful. Key limitations acknowledged by the authors include self-selection and sample biases (experienced, mostly Western users and retreat attendees), retrospective self-reporting, and the Study 1 sample being selected for transformation and distress which may skew results toward beneficial outcomes. They emphasise that the ReCiPE is a novel measure that requires further psychometric validation; the binary transformation used here simplified responses and reduced information about degrees of helpfulness. The authors caution about generalising these findings directly to clinical settings, as set and setting differ substantially between therapeutic and retreat or recreational contexts. They recommend future research using more rigorous sampling, longitudinal designs, clinical trials, validation of the ReCiPE with interval scoring, and exploration of mechanisms and moderators (including individual traits and contextual variables) to better guide practice and protocol development. In conclusion, the study suggests that the therapeutic role of challenging psychedelic experiences is contingent on challenge type and on the individual's ability to deploy adaptive responses. Acceptance/Reappraisal and Social Support/Disclosure strategies were particularly associated with emotional breakthrough in this sample, and fear management emerges as an important target for preparation and support in psychedelic-assisted interventions. The authors call for further work to validate these findings across diverse and clinical populations and to test targeted training or therapeutic elements aimed at improving coping during challenging psychedelic states.
