The role of drug availability and psychological proneness in opioid addiction was examined using longitudinal data from the Drug Abuse Reporting Program (DARP). The sample included 424 addicts who were followed up and interviewed approximately 12 years after admission to treatment in the DARP, and for whom admission, during-treatment, and 6-year follow-up data were also available. Drug availability and proneness were both found to be important for drug use at any given time--from initial stages of addiction as well as in Year 12 of the follow-up--but proneness was rated as relatively more important for opioid use in the later stages of the addiction career. Proneness measures contributed more to the prediction of long-term drug use outcomes.
利用药物滥用报告项目（DARP）的纵向数据，研究了药物可及性和心理易感性在阿片类药物成瘾中的作用。样本包括424名成瘾者，他们在进入DARP治疗约12年后接受了随访和访谈，并且有入院、治疗期间和6年随访数据。研究发现，药物可及性和易感性在任何给定时间（从成瘾初期到随访的第12年）对药物使用都很重要，但在成瘾生涯后期，易感性对阿片类药物使用的影响相对更为重要。易感性指标对长期药物使用结果的预测作用更大。
