Adaptive Mentalization Based Integrative Therapy (AMBIT) is a systemic, mentalization based intervention designed for young people with multiple problems including mental health problems. The purpose of this paper is to examine the impact of this approach both on clinical and functional outcomes for young people seen by a specialist young people’s substance use service between 2015 and 2018. About 499 cases were seen by the service during this period. Substance use outcomes were obtained for 383 cases using the Treatment Outcome Profile (TOP). Cannabis and alcohol use were the key substance use problems for 81% and 63% respectively. Functional outcomes using the AMBIT Integrative Measure (AIM) were obtained for 100 cases covering domains of daily living, socio-economic context, peer relationships and mental health. At treatment end, cannabis use reduced significantly (t = 10.78; df = 311; p = .00; Cohen’s d ES.61 as did alcohol use (t = 6.938; df = 242; p = .000; ES 0.44). Functional improvements were shown in five out of seven domains with highly significant total functional improvements on key problems selected by the client (t = 14.01; df = 99; p = .000; ES1.34). Measuring functional as well as clinical outcomes appears to reflect more accurately the overall benefit of the service to clients.

基于适应性心理化的综合疗法 (AMBIT) 是一种系统的、基于心理化的干预措施，专为有多种问题（包括心理健康问题）的年轻人而设计。本文的目的是检查这种方法对 2015 年至 2018 年间青少年物质使用专科服务机构就诊的青少年的临床和功能结果的影响。在此期间，该机构共诊治了约 499 例病例。使用治疗结果概况 (TOP) 获得了 383 例物质使用结果。大麻和酒精的使用分别是 81% 和 63% 的主要物质使用问题。使用 AMBIT 综合测量 (AIM) 获得了 100 个案例的功能结果，涵盖日常生活、社会经济背景、同伴关系和心理健康领域。在治疗结束时，t  = 10.78；df = 311; p  = .00；Cohen's d ES.61 以及饮酒情况（t  = 6.938；df = 242；p  = .000；ES 0.44）。在七个领域中的五个领域中显示了功能改进，对客户选择的关键问题的总体功能改进非常显着（t  = 14.01；df = 99；p  = .000；ES1.34）。衡量功能和临床结果似乎更准确地反映了服务对客户的整体利益。
