Refining a Novel Measure of Polysubstance Use: Applying the Cognitive Interview Method with People Who Use Drugs.
Article in Substance use & misuse, 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
backgroundCognitive interviewing is a methodological technique to elicit feedback on item comprehension and response categories by the target population. This method can be particularly relevant when working with vulnerable populations, such as people who use drugs, and for complex behaviors, including the use of multiple drugs (i.e., polysubstance use). While cognitive interviewing is recognized as an important technique, few case studies of the method have been published.
objectiveThe current manuscript details the cognitive interview method employed as part of the development of a novel polysubstance assessment tool.
resultsParticipants (n=28) with recent polysubstance use provided qualitative feedback using an iterative study design. Results detail the decision-making process of the study team to improve comprehension of complex behaviors, specifically simultaneous and same-day polysubstance use. Notably, the administration modality changed from self to interviewer-administered to facilitate participant understanding.
conclusionsFindings highlight the utility of the cognitive interview method in improving assessments of substance use.
