The study aim was to classify youths into homogenous groups based on their symptoms of Alcohol Abuse and Dependence. An NIDA-funded cross-sectional survey was administered to 622 middle and high school students in San Juan, Puerto Rico in 2000. Latent class analysis (LCA) examined the Alcohol Abuse and Dependence symptoms. Three distinct classes of drinkers were found: low (86.0% of sample), moderate (11.7% of sample), and high (2.3% of sample) severity classes which were distinguished by differing estimated probabilities of symptom reporting. The study has implications for the diagnosis of Alcohol Abuse and Dependence among Puerto Rican youths. Limitations are also noted.
这项研究的目的是根据青少年的酒精滥用和依赖症状将其分为同质群体。2000 年,美国国家药物滥用研究所资助的一项横断面调查在波多黎各圣胡安的 622 名中学生和高中生中进行。潜在类别分析(LCA)检查了酒精滥用和依赖症状。发现了三种不同的饮酒者群体:低(样本的 86.0%)、中(样本的 11.7%)和高(样本的 2.3%)严重程度群体,这些群体通过不同的症状报告估计概率来区分。该研究对波多黎各青少年的酒精滥用和依赖的诊断具有启示意义。同时也指出了一些局限性。
