Psychometric evaluation of the e-cigarette knowledge, attitude, and practice questionnaire among young students: a structural equation modeling approach.
Article in Frontiers in 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
Background: The growing popularity of e-cigarettes among young students has emerged as a pressing public health concern. Misconceptions about e-cigarettes persist widely, yet standardized tools to systematically evaluate youth knowledge, attitudes, and behaviors are limited. This study aimed to develop and validate a questionnaire evaluating e-cigarette knowledge, attitude, and practice among young students using a structural equation modeling framework. Methods: An initial e-cigarette knowledge, attitude, and practice questionnaire was developed and refined using classical test theory, including item analysis and exploratory factor analysis. A sample of 1,400 students undergraduate students were recruited from Kunming, China and Jakarta, Indonesia, yielding 1,333 valid responses (Kunming, Results: The final questionnaire retained 15 items: knowledge (4), attitude (8), and practice (3). Pearson correlation coefficients between each item and its respective dimension exceeded 0.4. Except for items P2 and P3, Conclusion: The final instrument demonstrated acceptable reliability and validity within the sampled populations from China and Indonesia. This tool provides a practical and evidence-based approach to assess young students' perceptions and attitudes towards e-cigarettes in public health research.
