Sub-Saharan Africa, with more than 56 million orphans worldwide, is the most affected region in terms of orphans to be cared for (UNICEF, 2014). The recently developed preventative approach Interaction Competencies with Children - for Caregivers (ICC-C; Hecker, Mkinga, Ssenyonga, & Hermenau, 2017) trains the essential interaction skills in working with children. The focus here is on strengthening a warm, sensitive and reliable relationship between caregiver and child as well as on non-violent education strategies. In a first pilot study the feasibility of the approach icould be demonstrated (Hermenau, Kaltenbach, Mkinga, & Hecker, 2015).

The study applies a two-arm cluster-randomized controlled design. The participating institutions will be randomly divided into intervention and control bodies. The follow-up examination should take place three months after the intervention. All caregivers in facility (N = approx. 150) and 25 randomly selected children (age: 6-12) per facility (N = 200) will be included in this study.

Sub-Saharan Africa, with more than 56 million orphans worldwide, is the most affected region in terms of orphans to be cared for (UNICEF, 2014). The few studies investigating children in African orphanages mostly showed inadequate care (Espié et al., 2011; Hermenau et al., 2011; Levin & Haines, 2007; Wolff & Fesseha, 1998, 1999). In addition to the lack of trained and competent caregivers, children are also confronted with violence and abuse in the orphanages themselves (Hermenau et al., 2011; SOS Children's Villages International & University of Bedfordshire, 2014). Abuse and neglect in orphanages, in addition to traumatisation, abuse and neglect in the families of origin, pose a considerable risk for the healthy development and mental health of children (Hermenau, Goessmann, Rygaard, Landolt, & Hecker, 2017). In addition to meeting basic needs (e. g. eating, drinking, basic medical care, etc.), sensitive and non-violent education in orphanages is crucial for the emotional and physical development of children. However, the focus of previous intervention studies has been on promoting a sensitive and reliable relationship between caregiver and child. Violence and maltreatment, on the other hand, received little attention (Hermenau et al., 2017).

The recently developed preventative approach Interaction Competencies with Children - for Caregivers (ICC-C; Hecker, Mkinga, Ssenyonga, & Hermenau, 2017) trains the essential interaction skills in working with children. The focus here is on strengthening a warm, sensitive and reliable relationship between caregiver and child as well as on non-violent education strategies. In a first pilot study the feasibility of the approach could be demonstrated (Hermenau, Kaltenbach, Mkinga, & Hecker, 2015).

The study applies a two-arm cluster-randomized controlled design and includes 20 to 25 orphanages. After an initial investigation, the participating institutions will be randomly divided into intervention and control bodies. The follow-up examination should take place three months after the intervention. In addition, feasibility data will be assessed in the intervention facilities only at the beginning and the end of the intervention. All caregivers in facility (N = approx. 150) and 10-15 randomly selected children (age: 6-12) per facility (N = 300) will be included in this study. Data of caregivers will be assessed with the help of self-administered questionnaires, whereas data of children will be assessed with structured interviews.

There is a clear and pressing humanitarian need for science to address the issue of care quality and maltreatment prevention in institutional care settings in a practical manner. Perhaps surprisingly in view of this, so far no evidenced-based prevention measures adapted for the limited resources in low-income countries have been developed and scientifically evaluated. This research project can address this need, with a scientifically rigorous evaluation of a violence and maltreatment prevention program that fosters the active involvement of local personnel and that considers the limited resources of school settings in low-income countries. Through these efforts this study may help more orphans to grow-up in a supportive atmosphere, maintaining their psychological well-being and improving their performance. This preventative program aims to make a significant impact on the psychological well-being of orphans in Tanzania.
