Assessing Readiness of Health Professions Students to Work With Patients Who Use Drugs: Construct Validity of the REDUCE-HARM Addiction Curricula Survey Tool.
Article in Substance use & addiction journal, 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
backgroundThe REadiness to Discuss Use, Common Effects, and HArm Reduction Measure (REDUCE-HARM) is a new survey instrument with 2 subscales intended to assess attitudes toward substance use and confidence in core addiction topics among health professions students. Previously, we validated its content via a modified Delphi process with interdisciplinary experts across the United States. This study assessed the construct validity and reliability of REDUCE-HARM among students in health professions to be used in developing and evaluating addiction-related curricula.
methodsWe sent the REDUCE-HARM to early-training nursing, nurse practitioner, pharmacy, and medical students using class-wide email distribution lists at 7 academic medical centers in the United States from December 2021 to October 2022. We evaluated construct validity and reliability for the complete REDUCE-HARM instrument and the attitudes and confidence subscales using psychometric testing. We used
resultsOf the 288 participants, 26% were nurses, 9.7% were nurse practitioners, 30.2% were pharmacists, and 34.0% were medical; 52.8% had prior addiction-related experiences. Principal component analysis and confirmatory factor analysis demonstrated a 2-factor structure of the REDUCE-HARM that corresponded with the subscale constructs of attitudes and confidence. Cronbach's alphas were .912 (95% confidence interval [CI] .896-.925), .798 (95% CI .765-.827), and .938 (95% CI .925-.947) for the complete REDUCE-HARM, attitudes subscale, and confidence subscale, respectively. There were significantly higher mean attitude scores (59.8 vs 57.8; scale: 12-72;
conclusionsOur analysis supports the construct validity and reliability of the REDUCE-HARM among early trainee U.S.-based health professions students and the benefit of direct addiction-related experiences. Future research should evaluate responsiveness to addiction-related educational programs and with additional trainee populations.
