The prevalence of addiction in forensic psychiatric patients (adolescents and adults) is unknown. Published figures are nearly always based on estimates or on old or select samples.
To determine the importance of addiction as a risk factor for recidivism in forensic psychiatric patients in the Netherlands and to determine the prevalence of addiction in this group and the prevalence of drug intoxication in group-members at the time they committed the offence.
We analysed one database relating to forensic psychiatric adolescents and two sets of data relating to tbs-patients (tbs='detained at her Majesty's pleasure').
The prevalence of addiction among forensic psychiatric patients could only be given approximately, but it was certainly high (more than 60%). Substance abuse or addiction often played a major role (in more than 30% of cases) at the time the offence was committed for which the detention order was issued.
Because substance abuse often played a role in the delinquent behaviour that led to the detention order, it may also be a risk factor for recidivism. More research is needed so that we can increase our knowledge about the most effective ways of treating substance abuse.
法医精神病患者（青少年和成年人）中成瘾的患病率尚不清楚。已公布的数据几乎总是基于估计或旧的或特定的样本。
确定成瘾作为荷兰法医精神病患者再犯风险因素的重要性，并确定该群体中成瘾的患病率以及群体成员在犯罪时药物中毒的患病率。
我们分析了一个与法医精神病青少年相关的数据库以及两组与被女王陛下拘押的患者（tbs）相关的数据。
法医精神病患者中成瘾的患病率只能大致给出，但肯定很高（超过60%）。在发出拘留令所针对的犯罪行为发生时，药物滥用或成瘾往往起主要作用（超过30%的案例）。
由于药物滥用常常在导致拘留令的犯罪行为中起作用，它也可能是再犯的风险因素。需要更多研究，以便我们能够增加对治疗药物滥用最有效方法的了解。
