摘要

本研究之目的在依據網路成癮診斷準則來建立網路成癮量表之切分點，依據不同之研究需求分別建立篩檢切分點及診斷切分點，以作為青少年網路成癮社區調查之工具。本研究以454名在校國高中生為研究對象，依據精神科醫師診斷性會談之結果求取網路成癮量表之適合切分點。ROC分析的曲線下面積比例為89.6%，顯示綱路成癮量表具有良好之區辨力。進一步分析顯示57/58為最佳之篩檢切分點，具有85.6%之敏感度，可作為兩階段診斷研究方式之適當篩檢工具。同時63/64為最佳診斷切分點，可以正確診斷87.6%之個案，可作為單階段調查之適當診斷工具。

The aim of this study was to establish the optimal cut-off points of the Chen Internet Addiction Scale (CIAS), to screen for and diagnose Internet addiction among adolescents in the community by using the well-established diagnostic criteria of Internet addiction. This survey of 454 adolescents used screening (57/58) and diagnostic (63/64) cut-off points of the CIAS, a self-reported instrument, based on the results of systematic diagnostic interviews by psychiatrists. The area under the curve of the receiver operating characteristic curve revealed that CIAS has good diagnostic accuracy (89.6%). The screening cut-off point had high sensitivity (85.6%) and the diagnostic cut-off point had the highest diagnostic accuracy, classifying 87.6% of participants correctly. Accordingly, the screening point of the CIAS could provide a screening function in two-stage diagnosis, and the diagnostic point could serve as a diagnostic criterion in one-stage massive epidemiologic research.
