Validation of the Brief Assessment of Stress and Eating (BASE) in cisgender gay men and lesbian women.
Article in Journal of eating disorders, 2025. 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
backgroundSexual minority adults are at elevated risk for eating disorders (EDs), yet existing screening tools have rarely been validated in this population. Most ED screening instruments have been validated in predominately cisgender, heterosexual female samples limiting their generalizability to populations with different symptom patterns. Validation studies in cisgender sexual minority (SM) adults are critical to improving detection and addressing disparities in ED identification. The present study evaluated the psychometric performance of the Brief Assessment of Stress and Eating (BASE), a validated 10-item screening tool that assesses DSM-5-aligned eating disorder symptoms and subclinical dysregulated eating behaviors, in a national sample of cisgender gay men and lesbian women.
methodsParticipants were 1,499 cisgender SM adults (61.7% gay men, 38.3% lesbian women) recruited from The PRIDE Study, a U.S.-based longitudinal cohort of sexual and gender minority adults. Respondents completed the BASE, SCOFF questionnaire, and the Eating Disorder Diagnostic Scale-5 (EDDS-5) which we used to derive probable DSM-5 eating disorder (probable ED) status. Receiver operating characteristic (ROC) and precision-recall (PR) curve analyses were conducted to evaluate classification accuracy and identify optimal thresholds.
resultsBoth the BASE and SCOFF performed significantly above chance in detecting EDDS-5-derived probable EDs. Among gay men, the BASE (AUC: ROC = 0.785, PRC = 0.702) outperformed the SCOFF (ROC = 0.744, PRC = 0.630). In lesbian women, the two screeners performed similarly (BASE AUC = 0.807; SCOFF AUC = 0.806). Optimal BASE thresholds varied by group with higher sensitivity at lower cutoffs (e.g., ≥ 7).
conclusionsThe BASE provides a reliable, efficient alternative to traditional instruments for screening eating disorders in sexual minority adults, with good performance for identifying EDDS-5-derived probable EDs. Findings support the BASE as a reliable and valid screening tool for use with cisgender SM adults in community, healthcare, and research contexts.
