Psychosocial correlates of performance-enhancing substance use intentions and prevention needs among recreational gym users: a theory-informed mixed-methods study.

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
backgroundPerformance-enhancing substance (PES) use is a potential public health concern in recreational fitness. Research suggests that use among recreational gym users is associated with psychosocial factors, gym culture, and peer norms.
objectiveThis study examined associations of Theory of Planned Behavior (TPB) constructs, selected Health Belief Model (HBM) constructs, knowledge, and risk acceptance with PES-use intentions and explored prevention needs using a mixed-methods design.
methodsA cross-sectional mixed-methods survey included 772 recreational gym users in Germany; 29.4% reported ever or current use of at least one of six assessed PES categories. Quantitative analyses examined TPB constructs, HBM-related constructs, knowledge, and risk acceptance. Qualitative data comprised 542 open-ended responses on prevention preferences.
resultsSubjective norms and lower perceived behavioral control over avoiding PES showed the strongest associations with higher PES-use intention. Greater knowledge was associated with lower intention, whereas higher risk acceptance, greater perceived benefits of PES use, and lower self-efficacy to resist PES were associated with higher intention. None of the examined psychosocial variables were significantly associated with the ever/current PES-use indicator. Qualitative findings emphasized credible information, peer-based support, and preferences for gym-based prevention approaches.
conclusionPsychosocial factors were associated with variation in PES-use intentions among recreational gym users. Prevention development may consider social norms, perceived control over avoiding PES, resistance self-efficacy, knowledge, and preferences for credible, context-sensitive information. Given the cross-sectional design, the findings should be interpreted as associations and as hypothesis-generating evidence for future prevention research.
