作者融合艾瑞克森的自我形成理論(Erikson’s Identity Formation Theory)和家庭溝通型態理論(Family Communication Pattern)建構 一個因果結構模式來解釋青台北青少年的媒體使用行爲。共有715位 就讀大台北地區公私立高中和初中的學生參與這個研究。作者使用 線性結構關係共變量分析法(LISREL)來找尋各變項間是否存在顯著 的結構關係。從分析的結果中發現：在心理上已完成自我成就(Identity-achievement) 的 青少年較傾向 於使用 和暴露於媒體 的知識性内容 。反之，在心理上未完成自我達成的青少年較傾向於使用和暴露於 媒體的娛樂性内容。生長於注重親子間理念溝通的家庭的青少年也 比較傾向於使用和暴露於媒體的知識性内容。注重親子間理念溝通 的家庭互動對青少年在心理上完成自我成就有正面的貢獻。此外， 青少年的年齡與父母之敎育程度對其媒體使用行爲與心理上的自我 形成狀況都有顯著之影響。

An integrated causal model on adolescent media use was proposed and evaluated using the Linear Structural Relations (LISREL) covariance analysis. In the proposed model, Erikson's identity formation theory and the family communication pattern theory were incorporated to examine adolescent’s media use in Taiwan. 715 students, aged 12 through 18, from junior and senior middle schools took part in the cross-sectional survey. Results from the study have largely confirmed the hypotheses that adolescent^ level of identity-achievement and a concept-orientation in parent-child communication style increased exposure to news reports but decreased consumption of entertainment content. Age and parents' educational levels also showed significant effects on the teens5 media use as well as on their identity-achievement levels and family communication style.
