The helioscope effect: A new framework for evaluating trauma-related memory processing in psychedelic experiences.
Article in Journal of psychopharmacology (Oxford, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundExisting tools assess psychedelic experiences, but none specifically measure altered processing of traumatic memories-a key mechanism in trauma-focused therapies and psychotherapy in general. The helioscope effect describes how psychedelics like psilocybin and 3,4-methylenedioxymethamphetamine (MDMA) enable revisiting challenging or traumatic experiences while remaining protected from re-actualization of trauma symptoms. This study introduces and evaluates the Helioscope Questionnaire, a novel scale for assessing memory-related processing during psychedelic experiences.
methodA cross-sectional, Internet-based survey was administered to 468 individuals (mean age = 32.9; 66.7% male) with self-reported psychedelic/MDMA use.
resultsThe final Helioscope Questionnaire comprised 21 items across 3 factors:
conclusionsThe Helioscope Questionnaire offers a novel, psychometrically robust tool for assessing therapeutic mechanisms of psychedelic experiences, particularly in relation to processing of difficult memories. Further research in clinical populations is warranted to evaluate its utility in predicting treatment outcomes.
