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.
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.
