本文主要目的在探討兒少社交媒體使用與人際關係之研究，以大台北地區國小高年級及國中七、八年級兒少為研究對象，共計有效樣本為730人。結果如下：
1.兒少使用社交媒體，主要動機為維持人際互動以及認識新朋友，常用功能為聊天與傳遞訊息。
2.不同年級兒少在「好友人數」方面有顯著差異。
3.不同性別的兒少在社交媒體的「使用方式」、「使用原因」、「使用功能」、「朋友關係」與「網路人際」達顯著差異。
4.不同年級兒少在使用「年資」、「每週使用時間」、「使用功能」、「使用原因」有顯著差異。
5.不同父母親教育程度的兒少在社交媒體的「使用方式」、「使用原因」、「使用功能」、「好友人數」有顯著差異。母親教育程度對「網路人際」與「朋友關係」皆達顯著差異。
6.以背景變項及「父母對兒少社交媒體使用態度」對網路人際關係分析發現，「母親教育程度」及「父母回應」達顯著差異。
7.以兒少社交媒體使用變項對人際關係分析發現，「聊天交友」及「情感維繫」達顯著差異。經由皮爾森相關分析發現，虛擬的「人際關係」與現實的「朋友關係」之相關係數高達.809，二者呈現高度正相關。
本研究根據研究結果提出建議，供家長、教師以及未來研究者之參考。
