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。以研究或安排課程為目的 時，一般會將年輕勞工(young workers)區分為青 少年(15-19 歲)與青年人(20-24 歲)兩個次群組。 本研究以有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1,200 份問卷，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)近六成有兼職 工作之科大生曾有過工傷或虛驚的經驗；(2)有 兼職工作之科大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%.
