Utility and usability testing of the FrESH (free from E-Cigarettes and smoking for health) web application: A qualitative 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
Background: Adolescent tobacco and e-cigarette use remains a major public health concern due to early nicotine dependence. Although digital cessation tools exist, only few have been systematically evaluated. The FrESH (Free from E-Cigarette and Smoking for Health) Web App was developed as part of the Stop Nicotine Addiction Among Secondary School Students (SNAASSS©) peer-led school intervention in Malaysia. This study reports a formative evaluation of the web app through expert utility and adolescent usability testing. Methods: A qualitative formative evaluation was conducted in two phases. Utility testing involved medical and user experience experts using Cognitive Task Analysis (CTA), think-aloud protocols, and semi-structured interviews. Usability testing was subsequently conducted with adolescent cigarette smokers, vape users, and dual users in a secondary school. Recorded interviews were transcribed verbatim and analyzed via thematic content analysis using NVivo v.14 software. Results: Experts evaluation focused on utility, identifying core strengths in educational content, self-monitoring tools, and motivational feedback mechanisms (e.g., progress tracking, money saved), while recommending simpler language, clearer dashboard outputs, and improved consent readability to enhance value. Usability testing with adolescents found the app learnable, visually appealing, and supportive, with good comprehension when content was structured. However, barriers included text-dense information, unfamiliar terminology, ambiguous tracker values, limited system feedback, navigation uncertainty, alongside concerns regarding data privacy. Conclusion: The FrESH Web App shows strong potential as a school-integrated digital cessation support tool for Malaysian adolescents. Findings provide actionable guidance to improve content clarity, feedback interpretability, navigation support, and youth-friendly consent processes. Further mixed-method evaluation across multiple schools is warranted to assess engagement and effectiveness.
