本研究主要目的在調查國中生酒行為，同時探討社會心理學因素、環境因素與飲酒行為之關係。以臺灣地區國中生為母群體，以二階段分層抽樣法進行抽樣，以班級為單位，利用自填式結構問卷進行資料收集，共得有效樣本5956名。本研究重要結果如下: 1.國中生每個月至少喝酒1-2次以上者佔15.3%;以性別來看時，每個月至少喝酒1-2次的學生，男生有18.4%，女生有12.1%，男生喝酒情形顯著較女生為高。以年級來看時，每個月至少喝酒1-2次的學生，一年級有13.8%，二年級有15.6%，三年級有16.3%，飲酒行為有隨年級而增加之趨勢，且三年級喝酒情形顯著高於一、二年級，二年級亦顯著高於一年級。 2.國中生未來六個月內有飲酒意圖者佔24.8%;以性別來看時，每個月少喝酒1-2次的學生，男生有28.6%，女生有20.7%，未來六個月內有可能飲酒，男生飲酒意圖顯著高於女生。以年級來看時，每個月至少喝酒1-2次的學生，一年級有22.3%，二年級有23.4%，三年有28.7%，未來六個月內有可能飲酒，三年級飲酒意圖顯著高於一、二年級。 3.影響飲酒行為因素的探討發現:與同學相比自己覺得較有偏差行為、對偏差行為的忍受程度愈高、自己對同儕壓力的感受性愈強、自我效能愈低、父母對孩子的關心與鼓勵愈少、對父母管教的遵從度愈低、自己與同儕對飲酒行為的贊同愈高、同儕飲酒行為愈多、父母飲酒行為愈高、父母對子女飲酒的態度愈開放者，則愈有飲酒行為。

The purpose of this study was to exam the drinking behavior and variables affecting alcohol use among junior high school students, including psychosocial and environmental factors. The participants chosen by cluster sampling method were 5956 junior high school students who were asked to respond to a self-reported questionnaire. The major findings of this study were as follows: 1. 15.3% of junior high school students drank alcohol at least one or two times a month. There were significant differences in gender and grades. The proportion of using alcohol at least once or twice a month among male and female students were 18.4% and 12.1%, while the proportion among the 7th, 8th and 9th graders were separately 13.8%, 15.6% and 16.3%. 2.24.8% of the junior high school students had the intention of alcohol use within the next six months. Male and female students accounted for 28.6% and 20.7% separately, which showed significant differences in gender. In addition, 28.7% of the 9th graders were likely to drink alcohol in the next six month, the proportion of which was higher than the 7th graders (22.3%) ad the 8th graders (23.4%). 3.Students with stronger deviant self-image, more tolerance of peer pressure, less self-efficacy, less parental nurturance, less parental monitoring, more personal and peer approval of alcohol use, more alcohol use by parents or peers, and more parental permissiveness were likely to have higher alcohol use.
