Prospective examination of the therapeutic role of psychological flexibility and cognitive reappraisal in the ceremonial use of ayahuasca
Bibliographic record
Abstract
BACKGROUND: Evidence suggests that psychedelic-assisted therapy carries transdiagnostic efficacy in the treatment of mental health conditions characterized by low mood and the use of avoidance coping strategies. AIMS: While preliminary evidence suggests that psychological flexibility and emotion regulation processes play an important role within psychedelic therapy, this prospective study addressed methodological gaps in the literature and examined the ability of ayahuasca to stimulate acute states of cognitive reappraisal and long-term changes in psychological flexibility and mood. The study also explored whether moderating factors predisposed participants to experience therapeutic changes. METHODS: = 261) were recruited from three Shipibo ayahuasca retreat centers in Central and South America and completed assessments on mood, psychological flexibility, and acute ceremonial factors. Expectancy, demand characteristics, and invalid responding were controlled for with several validity scales. RESULTS/OUTCOMES: Participants reported significant reductions in negative mood after three months, as well as increases in positive mood and psychological flexibility. Acute experiences of reappraisal during the ayahuasca ceremony exerted the strongest moderating effects on increases in positive mood and psychological flexibility. Increases in psychological flexibility statistically mediated the effects of acute psychological factors, including reappraisal, on changes in positive mood. CONCLUSIONS/INTERPRETATION: These results highlight the role of acute psychological processes, such as reappraisal, and post-acute increases in psychological flexibility as putative mechanisms underlying positive outcomes associated with psychedelics. These results also provide support for the integration of third-wave and mindfulness-based therapy approaches with psychedelic-assisted interventions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
