Validation of the Stimulant Use Motives Scale and Assessment of Its Associations with Psychosocial Functioning and Sexual Health in U.S. Men Who Have Sex with Men.
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
backgroundAmong men who have sex with men (MSM), stimulant use (e.g., cocaine, crystal methamphetamine) is both more frequent than in the general population, occurs within sexual settings, and is associated with elevated risk of HIV acquisition and with suboptimal adherence to pre-exposure prophylaxis (PrEP). Understanding stimulant use motives and their relations to patterns and consequences of use among MSM may be important to developing effective interventions unique to this population.
methodsIn the present study, we sought to validate the Stimulant Use Motives Scale (SUMS), an adaptation of the DMQ-R, among a U.S. sample of 237 HIV negative, adult MSM with past month stimulant use. Using Structural Equation Modeling, a four-factor model was estimated. The four factors were: 1) social motives (enjoying social events more), 2) enhancement motives (liking the feeling/being high), 3) coping motives (with emotions, problems, mood), and 4) sexual motives (enjoyment, less inhibited or nervous).
resultsThe 12-item four factor model demonstrated acceptable fit. Social motives were negatively associated with stimulant use consequences (
conclusionThe present study highlights the importance of addressing specific motives in targeted interventions, providing an understanding of stimulant use patterns and associated sexual risk for HIV among MSM.
