本研究旨在瞭解科技大學學生的自我效能對其工作安全意識之影響。為研究和安排課程之目的，通常會將年輕勞工(young workers)區分為青少年(15-19歲)與青年人(20-24歲)兩個次群組。本研究以兼職工作之科大學生為研究對象，採立意抽樣方式對10所大學實施問卷調查，共發出問卷1,200份，有效問卷共1,127份，有效回收率93.92%。以偏最小平方法路徑模式分析(partial least squares - path modeling, PLS-PM)進行假設驗證，研究結果發現：(1)近六成的兼職工作之科大學生曾有過工傷或虛驚的經驗；(2)兼職工作之科大學生的自我效能會透過「安全知識」和「安全動機」對「安全行為」具特定間接效果，其中以「安全知識」的中介效果強度最高達47.70%。

The study aims to investigate the effects of part-time employment university student’ self-efficacy on their safety awareness at work. For research and programming purposes, this group is often divided into two subgroups: adolescents (15-19 years) and young adults (20-24 years). In this study, 1,200 questionnaires were sent to 10 universities of science and technology, a total of 1,127 valid samples were collected. The valid response rate was 93.92%. The results were analyzed with a partial least squares - path modeling (PLS-PM) analysis to determine where the hypotheses were supported. Research findings include: (1) nearly 60 percent of part-time employment students of Science and Technology University had an injury or near-miss experience. (2) part-time employment students’ self-efficacy affected safety behaviors via the mediation of safety knowledge and safety motivation; and the safety knowledge had the most partially mediation effect, the strength of mediation reached to 47.70%.
