由於網咖的興起及線上電腦遊戲的普受歡迎，本研究以計劃行為理論 (Theory of Planned Behavior, TPB) 架構來建構大學生上網咖意圖的因果模式。本研究以東部某大學學生為研究母體，研究工具獲得美國麻州大學Ajzen教授首肯使用，經多次測試後於2002年3月正式蒐集資料，共獲得有效問卷378份，資料以LISREL 8.3作為研究樣本的結構方程式分析。研究結果顯示 (1) 上網咖的態度愈正面，上網咖的意圖就愈強，(2) 重要關係人的規範愈強，上網咖意圖愈弱，(3) 上網咖意圖不受朋友邀請、有時間、連線遊戲技術高超，及知覺上網咖容易等知覺行為控制的影響，(4) 上網咖經驗愈多，上網咖意圖就愈強。本研究獲得有關TPB理論架構之結論如下 (1) 本研究建構的東部某大學學生上網咖意圖模式，可以有效地預測上網咖意圖，(2) 預測上網咖意圖，「過去行為」比「知覺行為控制」重要，(3) 就上網咖意圖而言，受訪對象顯示出個人主義抬頭及主觀規範式微的趨勢。文末並就未來研究與教育界、家長提出建議。

Due to the popularity of internet café and on-line computer games for youngsters, this study intended to develop an intentional model of visiting internet café through structural equation modeling. The sample for this study was drawn from the undergraduate population in a university in eastern Taiwan. The survey instrument, with permission of Dr. Ajzen of the University of Massachusetts, was translated into Chinese and pilot tested. A total of 378 valid questionnaires were collected in March 2002. The data were analyzed using LISEREL 8.3 software. The results indicated that (1) the more positive the attitude toward visiting internet café, the stronger the intention; (2) the stronger the subjective norms, the weaker the intention of visiting internet café; (3) the intention was not influenced by the students’ perceived behavioral control; and (4) the more the past experience of visiting internet café, the stronger the intention. Three conclusions were drawn regarding TPB theoretical framework: (1) The intentional model effectively predict the respondents’ intention of visiting internet café; (2) In making prediction on one’s intention to visit internet café, past behavior was more influential than perceived behavioral control; (3) In terms of intention of visiting internet café, there seems to be a trend of rising individualism and falling normative influences. Suggestions and recommendations were made for future research and practice.
