About

This study aims to investigate the sociodemographic background as well as psychiatric comorbidities of adolescent substance users with substance use disorders. The study simultaneously evaluates biomarkers of stress and addiction, including long-term cortisol levels from hair samples and gene methylation in blood samples associated with substance use.

Our study also adapts, rolls out, and evaluates an evaluated multimodal treatment manual wich was originally intended for stimulant drug users (MATRIX). We adopt this manual to the needs and specifics of adolescents (MATRIX-A, A=adolescents) with substance use disorders of any substance, including cannabis, methamphetamine, and alcohol. Adolescents will receive group therapy sessions, individual therapy sessions, and medication if needed, while parents or professional caretaker will receive group sessions. Therapy outcomes will be examined in addition to parental distress and parenting skills.

Full description

As numbers of adolescent drug abuse have grown rapidly within the last couple of years, research on youth drug abuse and dependency has taken a new and vital role within the public healthcare system. For this reason, it is crucial to find new ways to effectively integrate adolescent patients into the health care system, as well as assign them to treatment options tailor made for the specific challenges and needs of this population. This study aims to investigate (a) sociodemographic background and psychiatric comorbidities in connection with adolescent substance abuse and dependence to enhance understanding of epidemiologic risk factors for developing drug dependency in adolescence, as well as benefit future treatment options.

It further aims to investigate (b) molecular and epigenetic mechanisms of addiction disorders in adolescents by analyzing methylation pattern, as well as proteome analysis of peripheral immune markers. The investigator's aim is a better understanding of the multimodal biological underpinnings of risk/resilience for addiction in youth on the molecular, cellular and circuit levels with a special focus on the changes within the stress and immune system in patients with addiction disorders and their family members.

Another research interest of this study concerns (c) adapting and evaluating new treatment options, tailor made for the adolescent population. For this reason the investigators aim to adapt, implement and evaluate a therapeutic program according to the MATRIX manual for the treatment of substance abuse, which consists of two group therapies for patients, as well as their parents (Evaluation time points: T0, T1, and T2).

Last, this study aims to (d) evaluate parental stress levels, parental communication skills and knowledge in connection with adolescent substance abuse.
