The Impact of Monetary Compensation on Responsiveness to Ecological Momentary Assessments: A Pilot Study of Sexual Minority Men in One Midwestern City.
Article in Sexually transmitted diseases, 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
backgroundWe conducted a pilot ecological momentary assessment (EMA) study in preparation for a prospective cohort study of the drivers of syphilis transmission among sexual minority men. Our objectives were: (1) evaluate the effect of monetary compensation (any versus no compensation and amount paid per survey) on participant responsiveness, and (2) evaluate acceptability and feasibility of the EMA smartphone app to capture sexual and other behaviors in the last 24 hours.
methodsWe enrolled 40 men in the 4-week pilot and assigned them to 1 of 2 groups (higher vs lower compensation). Participants completed daily surveys by responding to push notifications or self-initiating in the app. Participants received $5, $3, or $0 per survey depending on compensation group, survey type, and study week. We evaluated response rates overall, by compensation group, and over time, and described responses to a follow-up survey assessing acceptability and feasibility.
resultsThe overall median completion rate was 60.7%. The higher compensation group had higher completion rates for self-initiated surveys, which only they were paid for (median 75% vs 43%, P < 0.001). For study-initiated surveys, which both groups were paid for (but the higher compensation group slightly more), the lower compensation group had somewhat higher completion rates (median 94% vs 75%; P = 0.13). Response rates among both groups decreased over time.
conclusionsResponsiveness to daily EMA surveys was higher when participants received compensation. The amount received per survey appeared to be less important. Ecological momentary assessment may be a resource-effective supplement to traditional data collection methodologies in sexual health research.
