Psychometric Properties of the Chinese Version of Penn State [Electronic] Cigarette Dependence Index

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to realize the first evaluation of the psychometric characteristics of the Chinese version of the the Penn State University Electronic Cigarette Dependence Index Scale.

Detailed Description
-----------------
This study will use forward translation, reverse translation, and comprehensive methods to Chinese-translate the Penn State University Electronic Cigarette Dependence Index Scale to form a Chinese version of the Penn State University Electronic Cigarette Dependence Index Scale that is more in line with the Chinese language and cultural environment. This study will also verify its reliability and validity in a large sample population to form a formal version of the scale. The scale will provide an effective tool for evaluating the degree of e-cigarette dependence among young people and adolescents in my country.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| E-cigarette dependence | The Penn State Electronic Cigarette Dependence Index is a validated self-reported instrument assessing e-cigarette dependence.Possible scales range from 0(no dependence) to 20(high dependency). | Baseline |

| --- | --- | --- |
| Self-reported addiction | Measured by a 0-100 point scale：the higher the score of the participant, the more severe the dependence on e-cigarettes. | Baseline | 
| Time to first vape | Corroborative evidence for e-cigarette dependence：the shorter the time interval, the greater the dependence on e-cigarettes. | Baseline | 
| Vapes/day and vaping days/week | Corroborative evidence for e-cigarette dependence：the higher the frequency, the more severe the dependence on e-cigarettes. | Baseline |
