臺灣南部高中學生對於PM2.5的環境敏感度與防治行為意圖之研究

Abstract

本研究旨在探討臺灣南部高中學生對於PM2.5的環境敏感度與防治行為意圖之現況，及其與社會人口變項、細懸浮微粒PM2.5知識、防治態度、及防治自我效能之間的關係。透由簡單隨機方式抽樣臺灣南部地區(高雄市、臺南市、嘉義縣市、屏東縣)之普通高級中學8所，並以「高中學生PM2.5知識、防治自我效能、防治態度與防治行為意圖問卷」為研究工具，實際測得454份有效問卷，問卷回收率為94.78%。 研究結果顯示： 一、 南部高中學生在PM2.5知識、環境敏感度、防治態度、防治自我效能及防治行為意圖等整體方面皆為正向或偏高趨勢的表現。 二、 不同社會人口學特質中，南部高中學生於「性別」、「居住地」、「有無環境教育等相關活動之經驗」在PM2.5知識、環境敏感度、防治態度、防治自我效能或防治行為意圖方面有顯著差異。 三、 南部高中學生在PM2.5知識、環境敏感度、防治態度及防治自我效能皆與防治行為意圖有顯著的正相關。 四、 防治自我效能、防治態度及環境敏感度等三變項，可用以預測PM2.5防治行為意圖，其可解釋的變異量為67.2%，其中防治自我效能的影響力最大。

The aims of this study were to investigate the current situation of environmental sensitivity and preventive behavioral intentions of PM2.5 among senior high school students in southern Taiwan, and its relationship with social population variables, PM2.5 knowledge, preventive attitudes, and preventive self-efficacy. Eight senior high schools in southern Taiwan (Kaohsiung City, Tainan City, Chiayi County, Pingtung County) were sampled as a simple in a random way. A research tool was the questionnaire including "PM2.5 knowledge, preventive self-efficacy, preventive attitudes, environmental sensitivity and preventive behavioral intentions". The actual effective questionnaires were 454 (Recovery rate 94.78%). The results of this research were as follows: 1. PM2.5 knowledge, environmental sensitivity, preventive attitudes, preventive self-efficacy and preventive behavioral intentions of senior high school students in the southern Taiwan showed positive level or high performances. 2. The sociodemographic characteristics such as “gender”, “place of residence”, “experiences with or without related activities of environmental education” had significant differences at PM2.5 knowledge, environmental sensitivity, preventive attitudes, preventive self-efficacy and preventive behavioral intentions of senior high school students in the southern Taiwan. 3. PM2.5 knowledge, environmental sensitivity, preventive attitudes, and preventive self-efficacy of senior high school students in the southern Taiwan had significantly positive correlations with preventive behavioral intentions. 4. Three variables of preventive self-efficacy, preventive attitudes, and environmental sensitivity could significantly explain 67.2% of the variances of the preventive behavioral intentions, and the preventive self-efficacy was the main predictor toward the preventive behavioral intentions of PM2.5.
