本研究旨在探討「阿德勒學派團體諮商」對網路成癮青少年在網路成癮行為、自我概念、社會興趣等之立即性與長期性諮商效果。本研究採等組前後測實驗設計，係以新竹某國中18 名國二學生為對象，分為實驗組及控制組，實驗組成員接受每週一次，每次120 分鐘，共八次之團體諮商。本研究以網路成癮量表、自我概念量表、社會興趣量表為評量工具，兩組成員在團體開始一週前進行前測，團體結束一週內進行後測，並於團體結束第四週進行追蹤測。實驗組成員於團體前七次結束時填寫回饋表，並於團體最後一次結束時填寫總回饋表，研究者在團體結束後進行實驗組成員個別訪談，以暸解成員在參與團體後的改變情形。本研究發現阿德勒學派團體諮商對網路成癮青少年在網路成癮總量表和戒斷反應向度，自我概念，以及社會興趣中連結性向度皆具有立即性諮商效果；在網路成癮中時間管理向度，以及自我概念具有長期性諮商效果。本研究根據上述結果，提出若干具體建議，以作為輔導應用與未來研究之參考。

The purpose of the study was to explore the immediate and follow-up counseling effects of Adlerian group counseling on Internet addiction, self-concept, and social interest of adolescents with Internet addiction. The study used the quasi-experimental design. The subjects consisted of 18 adolescents with Internet addiction. They were eighth graders from a junior high school in Hsinchu. They were selected based on their report of Internet use through the Internet-Use Scale and interviews conducted by the researchers. These adolescents were assigned to an experiment group and a control group. The experiment group was treated with 8 sessions of Adlerian group counseling. Instruments for measuring the effects included Chen Internet Addiction Scale (CIAS), Self-Concept Scale, and Social Interest Scale. All the data were analyzed by one-way ANCOVA. Furthermore, the feedback and interview results of the experiment group members were both used to support the quantitative results of this research. The major findings of this study were: First, Adlerian group counseling had ignificant immediate effects on the subjects' Internet addiction, withdrawal symptoms of Internet addiction, self-concept, and connection of social interest. Second, Adlerian group counseling had significant long-term effects on the subjects' time management problems of Internet addiction, and self-concept. In light of above findings, recommendations are offered for counselors and for future research.
