Background: Multisystemic Therapy (MST) and Functional Family Therapy (FFT) are evidence-based Blueprint programs shown to be effective towards youth problem behaviors. Purpose: The present study aimed to investigate treatment outcomes following MST and FFT among Norwegian youths with serious behavior problems. Research design: Routine Outcome Monitoring (ROM) data of the Youth Level of Service/Case Management Inventory at intake and post-test was used along with measures of five national treatment goals. Study sample: The study is based on two samples of youths assigned to MST (n = 2018) and FFT (n = 453). Analysis: Data were analyzed separately for MST and FFT, to explore changes during treatment and accomplishment of the treatment goals. Results: At intake youths in MST showed a significant higher level of risk factors compared to those referred to FFT. Significant reductions in risk factors and behavioral problems were evident for both interventions. Follow-up results demonstrated sustained reductions of problem behaviors. Conclusion: Both treatments decrease risk factors and increase the completion of outcome goals. Implications of the results are discussed.

背景： 多系统治疗 (MST) 和功能性家庭治疗 (FFT) 是基于证据的蓝图计划，被证明对青少年问题行为有效。 目的： 本研究旨在调查有严重行为问题的挪威青少年 MST 和 FFT 后的治疗结果。 研究设计： 青少年服务水平/病例管理清单在入学和后测时的常规结果监测 (ROM) 数据与五个国民治疗目标的测量一起使用。 研究样本： 该研究基于分配给 MST（n  = 2018）和 FFT（n  = 453）的两个青少年样本。 分析： 分别对 MST 和 FFT 的数据进行分析，以探索治疗过程中的变化和治疗目标的实现。 结果： 与 FFT 相比，MST 中的青少年在入学时表现出显着更高水平的风险因素。两种干预措施都明显减少了风险因素和行为问题。后续结果表明问题行为持续减少。 结论： 两种治疗方法均可降低风险因素并提高结局目标的完成率。讨论了结果的含义。
