研究結果：研究發現，11.7%的學生及7.2%的社區民眾有吸毒意圖。羅吉斯迴歸分析顯示，在學生族群中，無吸菸習慣者(OR=0.203, p=0.033)有較低的吸毒意圖，國中生有較高的吸毒意圖(OR=4.243, p=0.017)；在社區民眾中，知覺行為控制能力越弱者(OR=1.246, p=0.046)有較高的吸毒意圖、受主觀規範越強者(OR=0.841, p=0.018)有較低的吸毒意圖。
Background: Drug abuse has been a serious national security problem. Although the government puts great efforts on seizing and defending against drugs crime, the harmful effect of drugs (especially emerging drugs) on students and community adults have not lower down.
Purpose: This study aimed to explore the differences in intention to drug use between the students and the community adults and their related factors. Method: This study used the database from a questionnaire survey of drug abuse prevention and control program held by the Public Health Bureau in Yunlin County between June and October in 2017. A total of 285 students and 321 community adults were included in the study. The dependent variable was "intention to drug use". For those who responded "will use drugs together" or "it depends" in the case of being invited by a good friend to use drugs, they were regarded as "having the intention"; for those who responded "never", they were regarded as "no intention". This study adopted the Theory of Planned Behavior as a framework to analyze related factors of the intention to drug use among the students and community adults.
Results: It showed that 11.7% of the students and 7.2% of the community adults have intention to use drugs. According to the logistic regression analysis among the students, non-smokers (OR=0.203, p=0.033) had lower possibility of having intention, while junior high school students had higher possibility of having intention (OR=4.243, p=0.017). For the community adults, those who have weaker perceived behavioral control (OR=1.246, p=0.046) had higher possibility of intention; those who have stronger subjective norm (OR=0.841, p=0.018) had lower possibility of intention.
Conclusion: The structure of the Theory of Planned Behavior could be adopted as a framework in the analysis of intention to drug use. The grade and smoking status of the students and the perceived behavioral control and subjective norm of the community adults were related factors of the intention to drug use, which implies the related factors of the intention to drug use between the students and community adults may be different.
Suggestions: Works of preventing smoking and drug use should be both emphasized in health educational programs in schools. Works of preventing drug use should be enforced in communities. Relevant departments could help people to create and maintain positive links with their family and the community to lower down their intention to drug use.
