Abstract: This study is a descriptive study to determine the drinking behavior of college students. The data were collected by 308 college students located in C province who agreed to participate in this study. There were positive correlations between problem drinking and the following factors: drinking attitudes (r = 0.145, p<0.05), subjective norms (r = 0.125, p<0.05), drinking intention (r = 0.486, p<0.01), parent descriptive norms (r = 0.281, p<0.01), friend descriptive norms (r = 0.426, p<0.01), general college student descriptive norms (r = 0.319, p<0.01), paternal problem drinking (r = 0.150, p<0.01) and maternal problem drinking (r = 0.128, p<0.05). There was negative correlation between problem drinking and perceived behavioral control (r = -0.650, p<0.01). Hierarchical regression analysis revealed that the following factors exert a significant influence on college problem drinking: religion (B = 0.679, p<0.05), perceived behavioral control (B = -0.824, p<0.001), friend descriptive norms (B = 0.659, p<0.001) and maternal problem drinking (B = 0.451, p<0.05). The explanatory power on college problem drinking was 53.4%.
