Method for Observing SMOKing and vaping bEhaviours (MOSMOKE): development and validation of a systematic observation tool.
Article in BMJ open, 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
objectivePolicies and interventions increasingly aim to reduce smoking in outdoor public spaces, but evidence on factors influencing smoking in specific locations remains limited. Systematic observation can unobtrusively assess behaviours in environmental contexts, reducing biases from self-report. This study aims to develop and test the reliability and validity of MOSMOKE (Method for Observing SMOKing and vaping bEhaviours): a new tool for assessing the number of people holding or inhaling a cigarette or vape in public spaces.
designMOSMOKE was adapted from a previously validated observation tool for assessing physical activity and well-being behaviours. Following piloting and refinement, inter-rater reliability for assessing smoking, vaping and age group classification was analysed using intraclass correlation coefficients (ICCs). A main study assessed criterion-related validity through 32 hours of observations over 4 days. A 2×2 study design was used, with four sites selected that varied by two environmental characteristics: presence of a smoking bin and adjacency to an office block.
settingFour public spaces in Manchester, UK.
resultsInter-rater reliability was 'good' (ICCs>0.75; n=4) or 'excellent' (ICCs>0.90; n=2) for smoking behaviours, and mostly 'good' (n=4) or 'excellent' (n=1) for vaping behaviours. Observed differences in smoking and vaping behaviours across sites aligned with prespecified hypotheses that smoking would be more prevalent near smoking bins (p=0.02) and office entrances (p=0.006), supporting criterion-related validity.
conclusionsThis study provides preliminary evidence that MOSMOKE is a reliable and valid tool for unobtrusively assessing smoking and vaping in public spaces. It can be used to evaluate policies and interventions targeting smoking or vaping in specific environmental contexts. MOSMOKE is freely available, with a detailed manual to support its use.
