Self-Actualization and the Integration of Psychedelic Experience: The Mediating Role of Perceived Benefits to Narrative Self-Functioning

Psychedelic research increasingly documents psychological benefits in both clinical and non-clinical populations, yet findings come from diverse outcome frameworks that are difficult to unify. The authors situate their work within a eudaimonic perspective of well-being, which emphasises narrative self-functioning—how people construct stories about who they are (self-insight) and who they might become (personal development)—as central to achieving optimal well-being or self-actualization. They argue that psychedelic experiences, particularly those involving ego-dissolution or self-transcendence, temporarily loosen entrenched self-referential patterns and therefore create an opportunity for lasting narrative change; post-psychedelic integration is presented as the clinical and informal process by which such changes may be consolidated. This study set out to test a preliminary structural model linking the extent of post-psychedelic integration to self-actualization, with perceived benefits to narrative self-functioning (self-insight and personal development) specified as a mediator. Integration was hypothesised to be a stronger predictor of perceived narrative benefits than mere frequency or duration of psychedelic use, and mental health status (current, past, or never diagnosed) was tested as a moderator. Because no established measure of integration existed, the investigators developed a novel integration scale and used cross-sectional survey data to evaluate these relationships as a foundation for future longitudinal work.

The study used a cross-sectional, online survey administered to participants recruited through social media and psychedelic-focused forums. Of 911 sign-ups, 890 consented and 748 completed demographic items; the analytic sample for the model-based analyses was roughly 750 respondents. Inclusion criteria were lifetime use of LSD and/or psilocybin, age over 18, and adequate English comprehension. Recruitment platforms included general social media (Facebook, Reddit) and psychedelic community sites, and participants were not compensated. The researchers obtained institutional ethics approval and informed participants about legal and physiological risks. Key measures included a 14-item integration scale created for this study (items averaged, α = .84) and an investigator-developed perceived benefits to narrative self-functioning measure composed of two subcomponents—self-insight (11 items) and personal development (5 items)—which loaded on a single factor with acceptable fit (RMSEA = 0.07, CFI = 0.93, SRMR = 0.04; α = .91). Self-actualization was assessed using the 30-item Characteristics of Self-Actualization Scale (CSAS; α = .92). Frequency and duration of psychedelic use were derived from retrospective reports of low/medium/high dose use over the past two years and years of lifetime use; microdosing frequency was excluded from the final frequency variable because integration was defined in relation to perceptual experiences. Mental health status was self-reported and categorised as currently diagnosed and suffering, diagnosed but not currently suffering, or never diagnosed/not suffering. Statistical analysis relied on structural equation modelling (SEM) implemented in Stata using maximum likelihood estimation with missing values. The primary analytic strategy tested whether perceived narrative benefits mediated the association between integration and self-actualization, controlling for frequency and duration of use. Mediation was examined via both a causal-steps framing (A, B, C, C' paths) and a product-of-coefficients approach (indirect, direct, total effects). Given sample size, a significance threshold of p < .001 was adopted. Moderation by mental health status was evaluated using multi-group SEM with chi-square difference testing between models constraining versus freeing path coefficients. An exploratory mediation analysis disaggregated the integration scale into four thematic categories—self-referential-oriented, mindfulness-oriented, communication/community-oriented, and intellectual-oriented integration—to examine their separate A, B, and C paths.

Participant characteristics: among the 748 respondents who provided demographics, mean age was 42.96 years (SD = 15.65), 62.03% were male, and 65.64% held at least a four-year college degree. Participants reported residence in 46 countries, with 59.09% from the United States. Mental health status groups comprised 401 non-clinical participants (53.61%), 25.67% previously diagnosed but not currently suffering, and 20.72% currently diagnosed and suffering. Substance-use reports indicated 90.29% had used psilocybin and 61.03% had used LSD; 19.12% reported ayahuasca use, 23.68% had used DMT, and 14.85% mescaline/peyote. Hypothesis testing: supporting Hypothesis 1, integration showed a substantially stronger association with perceived benefits to narrative self-functioning (β = .62; 95% CI [.55, .68], p < .001) than did frequency (β = .08; 95% CI [.05, .12], p < .001) or duration of use (β = .002; 95% CI [-.00, .01], p = .361). The three predictors collectively accounted for about 41% of the variance in perceived benefits; integration accounted for roughly 58.7% of the explained variance. In the base structural model, integration was positively related to self-actualizing characteristics (C-path; β = .44; 95% CI [.37, .51], p < .001). Mediation results: when perceived benefits were entered as a mediator, integration retained a positive but reduced direct association with self-actualization (C' path; β = .25; 95% CI [.17, .33], p < .001), while the A path (integration → perceived benefits) was β = .62 and the B path (perceived benefits → self-actualization) was β = .47, both p < .001. The indirect effect (product of A and B) was reported as B(.03) = .19, p < .001, indicating partial mediation; perceived benefits explained approximately 43.35% of integration's total effect on self-actualizing characteristics. Moderation by mental health status: multi-group SEM comparing models with constrained versus freely estimated paths produced a non-significant chi-square difference (Δχ2(14) = 19.87, p = .134), indicating that mental health status did not significantly moderate the model pathways. Exploratory integration-type analyses: disaggregating integration into four thematic types produced nuanced findings. For C-paths (direct relation to self-actualization while controlling covariates), self-referential-oriented integration (β = .10; p = .001) and communication/community-oriented integration (β = .14; p < .001) showed independent relationships to self-actualization, whereas mindfulness-oriented and intellectual-oriented integrations did not meet the stringent p < .001 criterion. For A-paths (relations to perceived benefits), self-referential-oriented (β = .31; p < .001) and mindfulness-oriented (β = .12; p < .001) integrations were significantly associated with perceived benefits; communication/community-oriented (β = .09; p = .009) and intellectual-oriented (β = .05; p = .064) were not. Introducing perceived benefits as a mediator led to loss of direct effects for self-referential and communication/community integration (consistent with full mediation for those domains). Product-of-coefficients tests indicated significant indirect effects for self-referential-oriented integration (indirect = .11, p < .001) and mindfulness-oriented integration (indirect = .041, p < .001), while communication/community and intellectual-oriented indirect effects did not reach the p < .001 threshold.

Amada and colleagues interpreted the results as broadly consistent with a eudaimonic model in which integration of psychedelic experience relates to higher levels of self-actualization, at least in part through perceived improvements in narrative self-functioning—greater self-insight and active personal development. The analysis showed that integration explained substantially more variance in perceived narrative benefits than did frequency or duration of psychedelic use, supporting the emphasis placed by psychedelic researchers and therapists on post-experience integration. The authors highlighted that integration techniques with a self-referential focus or mindfulness orientation were those that most clearly related indirectly to self-actualization via perceived narrative benefits. Reflective practices (for example, ‘‘reflecting on aspects of the experience that were important to me’’) were the most frequently reported integration activities, followed by spending time in nature; the latter aligns with prior work linking psychedelics to increased nature connectedness and self-transcendent emotions such as awe. The discussion notes that self-transcendent experiences need not be pharmacological—techniques like breathwork, binaural sound, and meditation may also elicit elements of awe and disidentification, and the authors explicitly state they are not encouraging illicit drug use. The paper acknowledges several important limitations the authors consider central to interpreting the findings. Chief among these is the cross-sectional, retrospective design, which precludes causal inference and may bias mediation estimates. Selection bias is also noted: recruitment from social media and psychedelic-oriented websites may have produced a sample unusually favourable to perceived benefits, and legal risks could have deterred some users from participating. Other limitations include missing data (roughly 750 of 911 provided complete responses for key scales), the lack of race/ethnicity information, and omission of potentially relevant variables such as psychological flexibility, preparation, intentions for use, and more comprehensive measures of narrative self-functioning. The authors recommend longitudinal, pre–post, or experimental designs and broader recruitment strategies to test the proposed structural model more rigorously and to examine potential bidirectional relationships and additional mediators or moderators.

The authors conclude that, in this cross-sectional sample of psychedelic users, greater engagement in post-psychedelic integration was associated with higher self-reported self-actualization, and that this relationship was partially mediated by perceived benefits to narrative self-functioning—specifically improved self-insight and personal development. They present the study as a preliminary structural model framed by eudaimonic well-being that may help unify findings across clinical and non-clinical populations, and suggest the results can inform the development of integration protocols. Given methodological constraints, the authors caution against causal interpretations and call for longitudinal and experimental research, ideally assessing participants before and after psychedelic experiences in novice users, to test and refine the model.
