Child and Parent-directed Individualized Psychotherapy (CPIP)

With CPIP the investigators opt for a manualized modular psychotherapy designed especially to meet the needs of children with internalizing disorders that suffered or still suffer from emotional or physiological neglect. CPIP helps the child to resolve rigid conflictual internal representations/ working models by individually focusing on caregiver-child interaction, mentalization based interventions with children and caregivers and working with the therapeutic transference relationship with the child and the caregiver. Treatment sessions will take place at CAP.

Clinical hypotheses:

The main hypothesis of the study is that for children with internalizing disorders and experience of emotional / physical neglect, CPIP \& enhanced caregiving support (intervention group) is superior in reducing internalizing symptoms compared to ECS alone (control group). Potential predictors of treatment response, as family context, gender and age, will be examined. Furthermore, the investigators will investigate possible treatment effects and mediating mechanisms, especially changes in DNA methylation profiles, HPA-dysregulation, cognitive-emotional styles, and emotional availability.

Additional elements: If the child additionally suffers from traumatic experiences of violence or sexual abuse, elements of Tf-CBT will be applied. Furthermore, elements of Interaction Guidance and ABC including video feedback will be applied in joint caregiver-child sessions. Treatment fidelity: Following the previous study, manualization, careful training and regular supervision will strive to ensure high treatment fidelity which will be systematically assessed in a random sample of two videotaped sessions per family.

Setting: Typically, 25 weekly sessions of approximately 50 minutes; in the clinician's office, family home, or child protection service office (due to the limited compliance expected from some families to attend regular therapeutic sessions). When conducting treatment sessions in the home environment, principles of established and evidence-based home visitation programs, like SafeCare or Nurse-Family Partnership Program will be applied.

Therapeutic elements: Reflective developmental guidance, modeling appropriate emotional availability, understanding of the meaning and function of the symptoms within relationships together with the caregivers, identifying and labeling feelings and actions, creation of a "neglect narrative" (parallel to a trauma narrative) and conflict interpretation together with the child.

Three treatment phases: Session 1-5: Building of a working alliance, assessment of family/individual problems and resources, focus formulation; Sessions 6-20: Therapeutic work on the focus; Session 21 to 25: Detachment of the working alliance, summarizing, concluding, fostering future development.

Therapeutic strategy: The inner conflict which is currently most pressing and actively determining the child's symptoms as well as jeopardizing mental development in the present will be identified and formulated during the first 5 sessions together with the caregivers and the child (therapeutic "focus"). The following treatment phase concentrates on the jointly identified problem/conflict that has been aggregated in the focus formulation. The setting will vary (number of parent-only, child-only, and caregiver-child sessions) as a function of whether the focus predominantly lies in the interpersonal (caregiver-child interaction) or intrapersonal realm.

Control Condition: Enhanced Caregiving Support (ECS) will serve as the control condition provided by the Allgemeine Sozialdienst (ASD - Community Social Services) of the two participating cities. According to German law (§ 27 SGB VIII), caregivers are entitled to receive caregiving support (CS; "Hilfe zur Erziehung") in cases where the child's wellbeing is jeopardized. CS generally includes supportive work across all child-relevant systems (family, neighborhood, (pre-)school, peer group etc.). Appointed social workers and educators provide parenting counseling, family support, and intensive child support according to an individualized helping plan ("Hilfeplan"). In more severe cases, children are placed in (temporary) day-care centers, children's homes, foster families etc. Within the context of the trial, the investigators will appoint an additional multi-systemic case manager to each case to enhance the quality of case coordination (enhanced CS; ECS). All children and families will receive ECS. the investigators will compare children receiving CPIP plus ECS to children receiving ECS only.
