Virtual Reality (VR-GINSO) as an Complement to Intervention for Alcohol and Cannabis Use in Youth in Residential Care

The goal of this RCT is to evaluate the effects of a virtual reality intervention on self-efficacy regarding alcohol and cannabis use among at-risk youth in various residential mental health treatment centers who have co-occurring disorders and are under the care of the association where they receive treatment. The main question it aims to answer is: • Does the VR intervention enhance the therapeutic effect of residential treatment on self-efficacy regarding alcohol and cannabis use? If there is a comparison group: Researchers will compare the intervention with the usual care (UC) that minors receive at the centers for the treatment of dual diagnosis to see if VR adds value to this treatment. Participants will be randomly assigned to each condition and will be evaluated before and after one month. In the experimental group, participants will receive a treatment session using VR software, during which they will undergo training in the following modules: The first phase is an assessment phase, during which objective measures are determined for 1) emotional recognition, 2) avoidance/approach toward related stimuli, 3) degree of compliance with social pressure, and 4) craving in the presence of the drug, exposure to cues, and/or conditioned contexts.

Matching Treatments to Cognitive Deficits in Offenders With Substance Use Disorders

The goal of this clinical trial is to investigate the effect of two types of cognitive remediation training on real-world behavioral outcomes including substance use, institutional adjustment, and recidivism following release from prison. Each training type is designed to target one of two subtypes of antisocial criminal offenders, who are characterized by either: 1) Attention to context-based deficits, or 2) Affective cognitive control-based deficits. The main questions it aims to answer are: Does matching deficit type with targeted cognitive training improve outcomes (relative to mismatched training)? What are the functional brain mechanisms that underlie treatment change? Participants will: Be assigned to cognitive training that either does or does not match their deficit type. Complete six one-hour sessions of cognitive skills training. Complete pre and post-training behavioral tasks assessing self-regulation deficits. Complete structural MRI scans and functional MRI scans assessing cognitive control. Complete post-treatment follow-up assessments evaluating self-regulation, adjustment, and stressful life events, substance use and recidivism.

Multisystemic Therapy-Emerging Adults Trial

This study's purpose is to test the effectiveness of a promising intervention for emerging adults (EAs) with mental illness (MI) and serious antisocial behavior in achieving the ultimate outcome of reduced antisocial behavior, and proximal intermediate outcomes. Multisystemic Therapy-Emerging Adults (MST-EA) is an adaptation of MST, a well-established, effective intervention for antisocial behavior in adolescents.

The Effectiveness of Forensic Outpatient Systemic Therapy: a Multiple Case Experimental Design

The purpose of this study is to investigate the effectiveness and mediators of Forensic Outpatient Systemic Therapy (FAST).

The Effectiveness of Blended Forensic Ambulant Systemic Therapy

The purpose of this study is to investigate whether blended Forensic Ambulant Systemic Therapy (FASTb) is equally effective as regular FAST (FASTr).

Multisystemic Therapy-Emerging Adults (MST-EA) for Substance Abuse

This study's purpose is to examine the effectiveness of a promising intervention for emerging adults (EAs) with alcohol and other drug (AOD) abuse and justice involvement in achieving the ultimate outcome of reduced criminal activity. The study will also examine that effect on intermediate outcomes as follows: 1) reduced AOD use; 2) greater gainful activity (increased educational success, employment and housing stability; decreased antisocial peer involvement and relationship conflict); 3) and greater improvement in self-regulation (self-efficacy, goal directedness and responsibility taking). The intervention to be tested is Multisystemic Therapy-Emerging Adults (MST-EA). MST-EA is an adaptation of MST, a well-established, effective intervention for antisocial behavior in adolescents.

Effectiveness of the Justice Diversion Halt-intervention

In the current study the effectiveness of the Dutch diversion measure Halt is investigated using a randomized controlled trial. Because of the thorough scientific substantiation of the intervention theory, it is hypothesized that receiving the Halt-intervention will lead to less recidivism in comparison to receiving no intervention.
