Developing a Linguistically Valid Japanese Version of the Chronic Pain Attribution Scale: Translation and Cultural Adaptation Process.
Article in Neuropsychopharmacology reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPatients' "pain attributions," or their beliefs about chronic pain causes, critically affect pain experience and recovery, potentially modulating responses to analgesics and psychotropics. Since many pain-mitigating drugs also impact psychological processes and brain functions underlying these attributions, such processes are relevant targets. The Chronic Pain Attribution Scale (CPAS) by Ashar et al. (2023) quantifies these beliefs. A Japanese version (CPAS-J) is needed to assess this psychologically relevant construct in Japanese populations. This study aimed to develop and linguistically validate the CPAS-J.
methodsThe CPAS-J was developed following International Society for Pharmacoeconomics and Outcomes Research guidelines, with permission from the original author. The process included forward translation by eight bilingual medical experts, reconciliation by a pain research team, back-translation by an independent translator, review by the original author, and a final consensus discussion to establish the definitive CPAS-J.
resultsThe linguistic validation identified challenges in distinguishing "cause" from "trigger" in Japanese. To enhance comprehensibility, the team combined "kikkake" (initiating factor) and "gen'in" (broader cause/origin). The finalized CPAS-J assesses perceived causes of pain.
conclusionsThe CPAS-J was successfully developed through a rigorous process. This tool supports research on pain attributions in Japanese-speaking populations and may improve our understanding of treatment responses by assessing a key psychological dimension of chronic pain that is linked to brain-based processes.
