較高學歷的戒菸者對香菸危害的認知程度較佳，但其在戒斷及改變吸菸行為時，因為介意別人的看法，因此有嚴重的社會壓力。本文是應用跨理論模式，對一位吸菸20年經驗的生物科技博士進行戒菸行為修正。戒菸衛教輔導期間為2012年10月18日至2013年4月15日，藉由會談、電訪以及電子郵件等方式收集資料。評估個案之戒菸困擾主要是對於再次戒菸缺乏自信，故反覆的復吸。筆者在戒菸過程中運用跨理論模式相關策略，提供戒菸輔導、諮商，個別性之策略安排，最終協助個案成功戒菸。期望藉由此篇報告，提供醫護人員在執行戒菸輔導時，協助個案持續戒菸行為的參考。

Although smokers who are highly educated understand the risks involved in smoking, they tend to be highly influenced by the opinions of others and thus subject to severe social pressures. This is a case report on the application of the transtheoretical model of behavioral change to a an individual with a PhD in biotechnology who had been smoking for 20 years. The effects of the developed smoking cessation intervention were investigated and data were collected through personal meetings, telephone interviews, and e-mail during a smoking cessation counseling program that lasted from October 18th, 2012, to April 15th, 2013. The results of the assessment indicated that the main problem encountered by the case when quitting was a lack of confidence in attempting to quit smoking after experiencing previous failed attempts. In this report, strategies related to the transtheoretical model were used and counseling was provided during the smoking cessation process. Individualized strategic methods were developed to be effective in highly educated people who smoke in order to achieve successfully cessation of smoking. This report serves as a reference for using the transtheoretical model of behavioral change in developing smoking cessation programs.
