YouTube是網路普及以來國人最常使用的線上影音平台，然而目前尚未有針對國中生使用YouTube的相關研究出現，因此本研究以使用者的角度出發，運用「使用與滿足」理論，探討國中生對於YouTube的使用動機、使用黏著度的狀態以及有沒有因為人口特質而有所不同，並且了解使用動機、使用黏著度、使用滿足程度三者之間的關係，另外也探討YouTube對國中生的影響，研究發現結果如下：
1. 使用黏著度在學校所在地區上沒有明顯差異，九年級、男生使用的黏著度會較高。
2. 使用動機以娛樂性動機為主，社交性動機較低，學校所在地區動機沒有明顯差異，資訊性動機九年級比七年級強，男生三項動機都比女生高。
3. 娛樂性動機強對使用黏著度高影響較大，資訊性則影響不顯著。
4. 娛樂性、資訊性動機強使用滿足程度會較高，社交性則影響不顯著。
