現階段臺灣正處疫情期間，我們對於臺灣青年的電子菸使用動機及易感知之甚少。透過社會學習理論與結果預期模型文獻，本研究假設疫情期間社群媒體菸品曝光度（媒體影響、社群影響）、正向結果預期（社交誘因、情感誘因、感官誘因）、負向結果預期（健康疑慮與成癮疑慮）與紙菸使用經驗對臺灣青年電子菸使用易感可能存在影響。本研究共蒐集到267位臺灣青年的有效樣本數據，並以結構方程模型檢驗數據有效性及驗證研究假設。結果顯示，僅有情感誘因、感官誘因與使用經驗會影響臺灣青年使用電子菸的易感程度。本研究實證結果將有助於政府菸害防制相關單 While the COVID-20 pandemic prevention, increasingly isolation may result in psychosocial stress, which is a risk factor for e-cigarettes. There is sparse evidence for the intention behind using e-cigarette among young Taiwanese. Based to social learningeory and outcome expectancy, this study provides empirical support for a motivation behind using e-cigarettes by testing the impacted variables derived from the integrated model of smoking on social media (social media and social effect), positive outcome expectation (social, emotion, sensation), negative out-come expectation (harm for health and addiction), and experience with conventional cigarettes. A cross-sectional e-survey was conducted among Taiwanese youths. A total of 266 smokers aged 19-25 years were recruited through an access panel. Findings indicated that in the COVID-19 context, the influences of emotional, sensational stimulations, and experience with conventional cigarettes positively predicts the level of intention for using e-cigarettes. The current study identified the psychosocial mechanisms of intention of e-cigarettes Taiwanese's user during the COVID-19 pandemic, which could be used as an empirical basis for the development of interventions to prevent tobacco. These efforts can help health promotion and reduce the costs of tobacco harm actually outweigh any financial benefits. ?
