The Impact of Policies Regarding E-cigarette on Adolescents and Young Adults' Cognition and Behavior for E-cigarette

The Impact of Policies Regarding E-cigarette(Trial) on Adolescents and Young Adults' Cognition and Behavior for E-cigarette: A Convergent Parallel Mixed-method Study Based on KABP Model.

Based on the Knowledge，Attitude，Belief and Practice model(KABP model), this study intends to use a mixed method to explore the influencing mechanism of youth and adolescents' cognition and behavior for e-cigarette before and after the promulgation of the new regulations on e-cigarette . Information from network epidemiology (including network links, text, images, audio, video, etc.) was captured to expand the data abundance, and the retrieval behavior of e-cigarettes and the trajectory changes of e-cigarette-related events were explored. Finally, summarize the data, integrate and explain the influencing mechanism of youth and adolescents' attention and cognition on e-cigarette, and provide ideas for subsequent e-cigarette control, as well as theoretical and practical basis for relevant departments to formulate corresponding policies.

Study Overview

• Status: Recruiting
• Conditions: E-Cig Use
• Intervention / Treatment: Other: Questionnaires set

Detailed Description

Mixed method will be used: the cross-sectional surveys will be conducted on the demographic characteristics, e-cigarette use intentions, e-cigarette use behaviors, attitudes towards e-cigarette , knowledge of e-cigarette harm, reasons for using e-cigarette and the degree of understanding of the new regulations on e-cigarette control ; semi-structured interviews will be conducted with some young people and adolescents interviewed by using phenomenology and qualitative research methods, and the content of the interview will be summarized and analyzed. The primary and secondary categories and dimensions are coded; the analysis results of quantitative data and qualitative data are combined to explain the influencing mechanism of the trial implementation of e-cigarette regulatory regulations on youth and adolescents' cognition of electronic cigarettes and changes in their use behaviors.

Using the network epidemiological method, use the "drop-down word deep mining function" of the 5188 marketing big data website to obtain the relevant keywords of "electronic cigarette", and use the Baidu index and 360 index tools to explore the retrieval behavior of electronic cigarettes and related electronic cigarettes Event trace changes.

Combined with online epidemiological data and mixed method study results, summarize the changes in youth and adolescents' cognition and use of e-cigarettes before and after the promulgation of the new regulations, and provide a theoretical basis for formulating e-cigarette control policies in the future.
