The helioscope effect: A new framework for evaluating trauma-related memory processing in psychedelic experiences.

Summary

The Helioscope Questionnaire is a new tool designed to assess how psychedelics affect the processing of traumatic memories. It was developed from a survey of 468 individuals who reported using psychedelics like psilocybin and MDMA. The questionnaire showed strong correlations with established measures of psychological insight and demonstrated its ability to predict mood changes. Additionally, having a trip sitter correlated with better scores, while MDMA use was associated with less avoidant distress.

Abstract

Existing 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. A cross-sectional, Internet-based survey was administered to 468 individuals (mean age = 32.9; 66.7% male) with self-reported psychedelic/MDMA use. The final Helioscope Questionnaire comprised 21 items across 3 factors: protection, exposure, and avoidant-distress. A composite Helioscope Score (HS) was derived from protection and exposure subscales. Convergent validity was demonstrated through strong correlations with the Psychological Insight Questionnaire. Discriminant validity was evidenced by moderate associations with the Mystical Experience Questionnaire and a lack of significant correlations with the Challenging Experience Questionnaire. Predictive validity was supported by the HS predicting positive changes in mood and attitude on the Persisting Effects Questionnaire, whereas avoidant-distress predicted negative changes. The scale also demonstrated incremental validity by providing explanatory power beyond established psychedelic effect measures. Additionally, the presence of a trip sitter was associated with stronger HS scores, and MDMA use was linked to reduced avoidant distress. The 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.
