Cross-sector Care for Children and Adolescents With Mentally Ill and Addicted Parents - Children of Mentally Ill Parents -Network - CHIMPS-NET

The central objectives of the study at hand are the implementation, evaluation and transfer of three evidence-based innovative forms of care (CHIMPS-Therapy, CHIMPS-MFT-Group, CHIMPS-Prevention-Single) for children and adolescents (aged 3 to 18 years) with mentally ill parents at the 19 participating study cites in 12 federal states of Germany. In addition, iCHIMPS, an online intervention based on the CHIMPS concept for the whole family, will be developed.

The four innovative forms of care include diagnostic, prevention and - if needed - therapy in order to treat psychological symptoms of children and adolescents as early as possible. Thereby, chronification will be prevented and the cycle of transgenerational transmissions of psychiatric disorders will be broken. Each of the four interventions will be evaluated in a separate prospective, randomized-controlled trial (RCT); overall, four randomized-controlled trials will be performed. Each of the four control groups receives treatment as usual (TAU). Each of the four studies will include two groups: one intervention group (IG) and one control group (KG), i.e. CHIMPS-T vs. KG (TAU), CHIMPS-MFT-group vs. KG (TAU), CHIMPs-P vs. KG (TAU), iCHIMPS vs. KG (TAU). Central psychosocial outcomes will be assessed at four time points (t1, t2, t3, t4) at baseline as well as after six, 12 and 18 months. Due to a longer development period, iCHIMPS will have three times of measurement over a period of nine months (baseline, post-intervention after 2 months as well as six-months-followup) within the project term. Outcomes will be assessed from the perspectives of the mentally ill parent, the partner (if available), every child and adolescent (0 - 9 years only external assessment; from 10 years of age additional self-assessment) and the professionals. A special characteristic of the study at hand is the comprehensive accompanying evaluation of medical biometry, health economics and qualitative evaluation.

In addition, various sub-projects for systematic implementation will be conducted:

optimization of pathway to care, knowledge and skills of professionals, development of a screening instrument and external quality assurance. In order to evaluate the effect of these three implementation strategies, an implementation study with a cluster-randomized trial was designed. Nineteen clinical centers are taking part in the implementation study. Nine of the nineteen clinical centers will receive the support of one of the three implementation strategies, the other ten clinical centers make up the control group and do not get a specific implementation support. The allocation is randomized. With three questionnaires in the investigator's implementation study we want to identify factors hindering or promoting implementation processes.
