Development of the Japanese version of the Challenging Experience Questionnaire.
Article in Neuropsychopharmacology reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
introductionThe therapeutic potential of psychedelics for various mental disorders has gained significant interest. Previous studies have highlighted that psychedelics induce psychoactive effects, including challenging aspects of experiences. These experiences are assessed using the Challenging Experience Questionnaire (CEQ), yet its Japanese version has been unavailable. This study aimed to create a Japanese version of the CEQ.
methodsWe followed the "Principles of Good Practice for the Translation and Cultural Adaptation Process for Patient-Reported Outcomes (PRO) Measures: Report of the ISPOR Task Force for Translation and Cultural Adaptation." Initially, two Japanese psychiatrists independently conducted the forward translations. These were then reconciled into a single version, which was back-translated into English. The original authors reviewed this back-translation for accuracy, leading to revisions through continuous dialogue until the original authors approved the final version.
resultsThe final, approved back-translated version of the CEQ is presented in the figure.
conclusionsThis study developed a Japanese version of the CEQ, enabling the assessment of challenging experiences during psychedelic-assisted therapy for Japanese speakers. Further studies are needed to assess the reliability and validity of this newly translated version.
