This paper discusses patient demographic and psychological characteristics as predisposing factors, and dose size and availability of alternative treatment systems as treatment variables in determining length of stay at MMTPs. In general, there is considerable evidence that predisposing factors and treatment variables interact in affecting retention rates. The implications of this interaction for research in MMTP effectiveness are discussed.
本文讨论了患者的人口统计学和心理特征作为诱发因素，以及剂量大小和替代治疗系统的可及性作为治疗变量，对确定药物滥用治疗项目（MMTPs）住院时间的影响。总体而言，有大量证据表明诱发因素和治疗变量在影响留存率方面相互作用。本文还讨论了这种相互作用对MMTP有效性研究的意义。
