A sample of treatment seeking clients was assessed at intake and 6, 12, 24 and 30 months later. Treatment-naive and treatment-experienced clients were compared in terms of baseline characteristics, 6-month outcomes, and predictors of these outcomes. Long-term outcomes of clients achieving an initially successful outcome were compared for the two groups. Results revealed significant short-term improvement for both groups, although treatment-experienced clients reported more serious drug use. The most consistent significant predictors of substance use outcomes were baseline severity of substance use and self-help participation. Outcome predictors unique to each group were also identified. Long-term outcomes for clients with an initial successful outcome tended to be better for treatment-experienced than treatment-naive clients. Both groups tended to have poorer outcomes as the follow-up duration increased. The results suggest that common and unique predictors of outcomes be considered in treating these two groups of clients. Additionally, treatment-naive clients may be at increased risk for poor outcomes even when initial success is achieved.
对寻求治疗的客户样本在入组时以及6个月、12个月、24个月和30个月后进行了评估。比较了初次接受治疗和有治疗经验的客户在基线特征、6个月的结果以及这些结果的预测因素方面的情况。对两组中最初取得成功结果的客户的长期结果进行了比较。结果显示两组均有显著的短期改善，尽管有治疗经验的客户报告的药物使用情况更为严重。药物使用结果最一致的显著预测因素是药物使用的基线严重程度和自助参与情况。还确定了每组特有的结果预测因素。最初取得成功结果的客户的长期结果，有治疗经验的客户往往比初次接受治疗的客户更好。随着随访时间的延长，两组的结果往往都更差。结果表明，在治疗这两组客户时应考虑结果的共同和独特预测因素。此外，即使初次取得成功，初次接受治疗的客户出现不良结果的风险可能也会增加。
