Randomized controlled trials were conducted at two residential drug abuse treatment facilities to compare programs that differed in planned duration. One trial compared a 6-month and a 12-month therapeutic community program (n = 184), and the second compared a 3-month and a 6-month relapse prevention program (n = 444). Retention rates over comparable time periods differed minimally by planned treatment duration, and the longer programs had lower completion rates. There was no effect in either trial of planned treatment duration on changes in psychosocial variables between admission and exit or on rates or patterns of drug use at follow-up between 2 and 6 months after exit.
在两个住院药物滥用治疗机构进行了随机对照试验,以比较计划疗程不同的项目。一项试验比较了为期6个月和12个月的治疗社区项目(n = 184),另一项试验比较了为期3个月和6个月的预防复发项目(n = 444)。在可比时间段内,留存率因计划治疗疗程的不同而差异极小,且疗程较长的项目完成率较低。在两项试验中,计划治疗疗程对入院和出院之间心理社会变量的变化,或出院后2至6个月随访时的药物使用率及模式均无影响。
