大學生細懸浮微粒防治行為意圖及其相關因素之研究－以臺北地區某兩所大學為例

Abstract

本研究目的在探討大學生PM2.5防治行為意圖現況，以及社會人口學變項、環境敏感度、PM2.5防治知識、PM2.5防治態度對PM2.5防治行為意圖之影響。以方便性取樣選取臺北市某兩所大學之學生，並修編「大學生環境敏感度、PM2.5防治知識、態度與行為意圖調查問卷」作為研究工具，共取得800份有效樣本。臺北市大學生對環境敏感度為正向敏銳程度；PM2.5防治知識屬中上程度瞭解；PM2.5防治態度為正向態度；PM2.5防治行為意圖偏高。在PM2.5防治行為意圖表現，女大學生優於男大學生。大學生的就讀科系對PM2.5防治行為意圖具有顯著影響效果；然而年級不會顯著影響PM2.5防治行為意圖表現；「參加環境教育相關課程」可顯著提高PM2.5防治行為意圖。而環境敏感度、PM2.5防治知識、PM2.5防治態度對PM2.5防治行為意圖呈現顯著正相關。 複迴歸分析得知大學生「環境敏感度」、「PM2.5防治知識」與「PM2.5防治態度」共可解釋36%「PM2.5防治行為意圖」的變異量。將變項放入多元逐步迴歸分析，「環境敏感度」、「PM2.5防治態度」、「性別」、「PM2.5防治知識」有效解釋39.7%「PM2.5防治行為意圖」變異量，其中又以PM2.5防治態度對於PM2.5防治行為意圖的預測力表現最高。

The aims of the study were to investigate the PM2.5’s preventive behavioral intentions, and explore the correction between its related factors for college students of two universities in Taipei area. Data were collected by questionnaires with a total sample of 800 college students in Taipei area. The students in this study included freshman, sophomore, junior and senior students.The environmental sensitivity of the students was positive. The scores of PM2.5 preventive knowledge were above average. The PM2.5 preventive attitude of the students was positive, and the PM2.5 preventive behavioral intentions of the students were good. Gender, grade, college and the experience of the environmental education influenced the PM2.5’s preventive behavioral intentions significantly. The PM2.5 preventive behavioral intentions were positively correlated with the environmental sensitivity, PM2.5 preventive knowledge and also positively correlated with PM2.5 preventive attitude.Environmental sensitivity, PM2.5 preventive attitude, gender, and PM2.5 preventive knowledge could significantly predict the 37.9% variance of PM2.5 preventive behavioral intentions. Among these factors, the PM2.5 preventive attitude was the best predictor for PM2.5 preventive behavioral intentions.
