Background and study aims
Children from substance (drug) abusing families have a high risk of developing psychological or substance related disorders in adolescence or early adulthood. However, in Germany there are few prevention programs aimed at reducing psychological stress for these children, and to date none have been scientifically tested. The aim of this study is to develop and test a modular group program called Trampoline for 8- to 12-year-old children from substance-abusing families in Germany.

Who can participate?
Children aged 8-12 who have at least one drug-abusing parent

What does the study involve?
Participants are randomly allocated to receive either the Trampoline program or treatment as usual.
The Trampoline program consists of nine modules (each 90 minutes) including exercises, role play, relaxation techniques, discussions and education. Before and after the program and 6 months later all participating children are assessed using questionnaires about current parental substance use, stress level and coping strategies, family relationship quality, self-worth, self-efficacy and satisfaction with the intervention. The parents also report on several of these areas and on parenting style and child behaviour.

What are the possible benefits and risks of participating?
The results of this study will provide fundamental information on the effectiveness of a structured group prevention program for German children from substance abusing families, helping to create a more effective system of help for this high-risk group. There are no physical or psychological risks for participants.

Where is the study run from?
German Center for Addiction Research in Childhood and Adolescence (Deutsches Zentrum für Suchtfragen des Kindes- und Jugendalters [DZSKJ]) (Germany)

When is the study starting and how long is it expected to run for?
October 2008 to March 2012
