Further adaptation of cross-commodity purchase task methodology: The impact of preference rank on demand.
Article in Experimental and clinical psychopharmacology, 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
A behavioral economic framework of alcohol use posits that alcohol use is a temporally extended pattern of behavior and occurs in contexts in which other response options are available. Hypothetical purchase tasks are based in behavioral economic theory and allow for researchers to pinpoint demand for commodities. An extension of purchase task methodology, cross-commodity tasks examine demand for a substance when two or more commodities are concurrently available. Recent research has extended these tasks to examine the impact of competing activities on alcohol demand. The present study extends this work by examining the extent to which rank-order preference for alternative activities would differentially impact demand for alcohol and serve as substitutes. Participants were crowdsourced via Prolific and completed a rank-order assessment of preference of activities and hobbies, an alcohol purchase task, and measures of suitability and rewarding value of alcohol-related activities. They responded to three separate cross-commodity tasks in which the highest, second-highest, or lowest preferred activity was presented at fixed low cost, while the price of alcohol increased. Results indicated that though rank preference did not impact substitutability of activities for alcohol, demand for alcohol was greater suppressed in the presence of high-preferred than low-preferred activities. Additionally, reported consumption of activities was greatest when the activities were highly preferred. Taken collectively, results highlight the utility of purchase task methodology and demand curve analyses in identifying alternative activities and the need for continued research exploring the functional reinforcing components of alternative activities to incorporate in interventions for hazardous alcohol use.
