依附關係是青少年與依附對象之間一種互惠、持久、情緒與生理的連結關係，在依附關係下，青少年會透過依附行為尋求依附對象的認同與保護，同時在青少年階段一直被視為型塑自我的重要關鍵時期，青少年藉由生活中重要他人的言語或非語文的反應判斷自己的能力，並不斷藉由成長過程中群體和個體互動之歷程，使自我概念逐漸成形。本文觀察發現，大多數對於依附關係或自我概念的研究，只從個別的觀點切入討論，似乎忽略了自我概念是一個獨立的概念與統整的個人特質。本研究採用「臺灣教育長期追蹤資料庫」問卷資料，於2005年下半年第三波調查中之高中、五專及高職的二年級學生為樣本，計有效樣本為10,788人，男生5,398人，女生5390人，針對青少年的依附關係和自我概念的關聯性進行分析。研結果發現：(1)依附關係和自我概念具有相關存在；(2)自我概念與母親、同儕之間的安全依附不僅具有正向的相關，且其關係是發展性的；(3)高中生愈依附於母親，但與學校關係愈疏遠，則其自我價值越高；(4)與母親的依附關係會影響青少年不同面向自我概念的發展。

Attachment is a kind of mutual and lasting emotional and physiological linking relation between juveniles and their attaching objects. Under the attaching relation, juveniles will seek for the recognition and protection of attached objects through attaching behaviors. At the same
time, the adolescence has been regarded as the critical period of shaping self. Juveniles judge their own capabilities by the language and non-language reaction from significant others .The self-concept is gradually formed through the interaction process between groups and individuals
during growing course. The research finds that most studies about attachment or self-concept just discuss from individual aspect, and seem to neglect that self-concept is an independent concept and integrated personal traits. The research analyzed the relativity between juvenile attachment and self-concept.It takes the sophomores of senior high schools, colleges and senior vocational schools surveyed the third time in the latter half of 2005 by by “Taiwan Education Panel Survey”
(TEPS) as researching objects. There are 10,788 effective samples, including 5,398 boys and 5390 girls. The research finds that: (1) there is relativity between attachment and self-concept; (2) self-concept positively relates to the firm attachment with the mother and peers, and the relation is progressive; (3) senior high school students possess higher self-worth when they attach more firmly to the mother and estrange farther from the school; (4) the attachment with the mother will affect the development of various aspects of adolescent self-concept.
