Product moment correlations were calculated between 17 psychosocial characteristics of 216 heroin addicts and their lengths of stay for first and second admissions to the dame methadone maintenance program. None of the variables which were related to retention during the first admission was associated with retention during the second admission. The conclusion was drawn that the relationships between addict characteristics and length of stay vary according to admission, and it would be unwise to use addicts' former treatment experiences to predict latter responses.
计算了216名海洛因成瘾者的17种心理社会特征与其首次和第二次进入同一项美沙酮维持治疗项目的住院时间之间的积差相关性。与首次住院期间留存情况相关的变量,均与第二次住院期间的留存情况无关。得出的结论是,成瘾者特征与住院时间之间的关系因入院情况而异,利用成瘾者以前的治疗经历来预测其后续反应是不明智的。
