先前使用聚类分析的研究发现，酒精和可卡因滥用者可分为重度（B型）和轻度（A型）亚组。本文试图在521名住院病人、门诊病人和不寻求治疗的酒精、可卡因、大麻和鸦片滥用者的样本中复制和扩展这些发现。对符合DSM-IV酒精、可卡因、大麻和阿片类药物依赖或滥用标准的子样本进行聚类分析发现，A型/ B型的区别在很大程度上适用于所有药物。a型吸毒者占所有药物滥用者的60%，在接受治疗的滥用者中约占一半，他们在各种药物滥用和精神病学测量方面的得分低于b型吸毒者，这些测量是在摄入和6个月的随访中进行的。
Previous research using cluster analysis has found that abusers of both alcohol and cocaine can be categorized into mole severe (Type B) and less severe (Type A) subgroups. This article sought to replicate and extend these findings in a sample of 521 inpatients, outpatients, and nontreatment-seeking abusers of alcohol, cocaine, marijuana, and opiates. Cluster analyses of subsamples that met the DSM-IV criteria for dependence or abuse for alcohol, cocaine, marijuana, and opiates found that the Type A/Type B distinction was largely generalizable across drugs. Type As - who consistently accounted for about 60% of all substance abuse and about half of abusers in treatment - scored lower than Type Bs on a variety of substance abuse and psychiatric measures that were administered both at intake and at a 6-month follow-up.
