我们采用潜在的过渡分析(LTA),以表征过渡随着时间的推移,在一年级大学生的物质使用行为配置文件。建模物质使用行为作为一个分类的潜在变量的优势进行了论证。在秋季和春季学期的大学生样本(N=718)中评估了酒精使用(任何饮酒和酗酒),香烟使用和大麻使用。确定了14天物质使用行为的四个特征:(1)非使用者;(2)吸烟者;(3)酗酒者;(4)饮酒者使用大麻。在这两个时期,最普遍的行为特征是非用户(超过一半的学生有这种特征),其次是酗酒者和酗酒者。吸烟者是最不普遍的行为特征。性别、种族/民族、早期饮酒、高中成绩、荣誉项目成员资格和友谊目标都是物质使用行为特征的重要预测因素。
We apply latent transition analysis (LTA) to characterize transitions over time in substance use behavior profiles among first-year college students. Advantages of modeling substance use behavior as a categorical latent variable are demonstrated. Alcohol use (any drinking and binge drinking), cigarette use, and marijuana use were assessed in a sample (N=718) of college students during the fall and spring semesters. Four profiles of 14-day substance use behavior were identified: (1) Non-Users; (2) Cigarette Smokers; (3) Binge Drinkers; and (4) Bingers with Marijuana Use. The most prevalent behavior profile at both times was the Non-Users (with over half of the students having this profile), followed by Binge Drinkers and Bingers with Marijuana Use. Cigarette Smokers was the least prevalent behavior profile. Gender, race/ethnicity, early onset of alcohol use, grades in high school, membership in the honors program, and friendship goals were all significant predictors of substance use behavior profile.
