Developing a utility value set for the Alcohol Quality of Life Scale-Brief (AQoLS-Brief) using a discrete choice experiment.

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
backgroundThe Alcohol Quality of Life Scale-Brief (AQoLS-Brief) is a patient-reported outcome measure developed with input from individuals with alcohol use disorder (AUD). This study aimed to develop a utility set for the AQoLS-Brief based on general population preferences to support cost-utility analyses.
methodsWe conducted a discrete choice experiment with duration in a probabilistic sample of French adults (n = 704). Participants chose between paired comparisons of health states described by seven AQoLS-Brief dimensions of varying survival durations. Conditional logit models with interactions between attribute levels and time were used to estimate utility decrements. These anchored coefficients were used to compute quality-adjusted life years (QALY) weights for all 16,384 possible AQoLS-Brief health states.
resultsRespondents reported that the tasks were understandable, realistic, and that all attributes were considered. Utility weights ranged from 1 for full health state to − 1.1 for worst state; 23.9% of states were valued as worse than dead. The two items most heavily weighing down the utility set were “Missing out on family life” (–0.59) and “Financial difficulties” (–0.45), highlighting the central role of social and economic functioning in the perceived burden of AUD. Substantial decrements were also observed for “Feeling of wasting my life” and “Life revolving around alcohol.”
conclusionsThis study provides a QALY-anchored value set for the AQoLS-Brief, enabling its use in cost-utility analyses. The findings underscore the importance of social, emotional, and financial domains in AUD-related quality of life. Further cross-cultural validation and responsiveness testing in clinical settings are needed.
