Assessing knowledge, attitudes, and barriers to opioid overdose among college students.
Article in BMC public health, 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
backgroundCollege students are a key population for opioid use, misuse, and subsequent exposure to overdose events. However, their knowledge and attitudes in response to opioid overdose warrant further study. To assess this gap, we surveyed graduate and undergraduate students about their opioid overdose knowledge, attitudes, self-reported competence, readiness to act, and concerns or barriers to intervention.
methodsWe conducted a cross-sectional survey of 252 undergraduate and graduate students at a large public university in the southern United States. Opioid overdose knowledge was assessed using the 45-item Opioid Overdose Knowledge Scale (OOKS), and attitudes toward overdose response—including perceived competence, readiness to act, and concerns—were measured using the Opioid Overdose Attitudes Scale (OOAS). Independent-samples t tests were used to compare knowledge and attitude scores across selected groups relevant to overdose education and naloxone training, including pre-health status and prior overdose prevention training. Open-ended responses regarding interest in naloxone training were analyzed using thematic analysis.
resultsParticipants demonstrated moderate overall overdose knowledge (mean OOKS score: 28.2 ± 8.6), with stronger performance in naloxone-related domains and persistent gaps in recognizing overdose risk factors and signs. Students with prior overdose prevention or naloxone training consistently reported higher knowledge, perceived competence, and readiness to intervene compared with untrained peers. Despite limited prior training (9.9%), nearly two-thirds of participants expressed interest in receiving naloxone training. Thematic analysis identified “Preparedness,” “Helping Others,” and “Confidence” as motivators and “Low Perceived Risk,” “Time Constraints,” and “Stigma” as barriers.
conclusionAlthough students exhibit moderate overdose knowledge, targeted naloxone training is essential for enhancing their competence and readiness to address opioid overdose. Tailored campus programs that address identified barriers and leverage motivational themes may strengthen emergency response and reduce overdose fatality.
