Empowering Youth in Care Against (re-)Victimization (Subproject 4): A Randomized Balanced Factorial Trial Examining an Internet-based Prevention Program for Primary Caregivers

Given that childhood victimization leads to an increased vulnerability for subsequent revictimization in adolescence, findings highlight a strong need for evidence-based prevention programs targeting children with a history of child maltreatment as a high-risk population of revictimization. However, evidence-based programs for foster parents that aim to prevent revictimization of the child, while addressing the needs of the caregivers are scarce. In order to develop and tailor such services to foster parents (and youth in care) with maltreatment experiences, we developed a consumer-informed conceptual model in a prior project (EMPOWERYOU SP3) that outlines the key mediators which may impact upon the risk of revictimization and how we plan to address these with different intervention components. Thus, in subproject 3 the conceptual model and the online-intervention components were developed, involving the participants themselves as well as relevant stakeholders. The usability of the online-intervention and the feasibility of the clinical trial (EMPOWERYOU SP4) was piloted in subproject 3 (March 2021 - September 2021).

In subproject 4, we will conduct a factorial study to tear apart the main effects of each intervention component on the mediator and outcome of interest, including potential interaction effects. This will help optimizing the intervention approach. The full online-intervention comprises five content modules and a coach, who is supporting the caregiver with up to four phone-calls (50 minutes each) and short message service (SMS) or e-mail reminders. Caregivers have two weeks to work through one module. Every caregiver will receive the first two basic modules on parental self-care and child´s self-worth and emotional regulation. This allows us to offer some level of support in all conditions including the condition with the lowest component level across all factors.

Based on the MOST principles, this study will use a 2 x 2 x 2 x 2 full factorial design by randomly allocating families with equal probability to one of 16 experimental conditions. However, this factorial experiment does not represent a 16-arm randomized controlled trial (RCT). The ultimate goal is to choose from a set of four intervention components with two levels each (on/off) the one(s) that best reduce and prevent (re-)victimization. The following intervention components have been selected (three content components, one engagement/adherence component):

1. Component: "Watch out!" (on/off): Improving relationship-related risk detection and self-protective behavior
2. Component: "You are safe here" (on/off): Improving relationship-related safety and facilitating solid relationships
3. Component: "Who am I and where do I belong?" (on/off): Supporting the child constructing an identity
4. Component: "My Coach" (on/off): Professional support of the caregiver in form of up to four phone calls with a coach (i.e., one call per module 1&2 (combined), 3, 4, and 5).

The primary research objectives are:
