- Brief Summary
More than 1.7 billion children worldwide experience violence in their upbringing. Prevalence rates are particularly high in Africa. Toxic stress associated with violence impacts the developing brain. This affects behavioral, social, and emotional functioning of children. The present project will test an intervention that simultaneously aims at reducing violence against children at home and at school. Within the project, (1) the feasibility, acceptability, and cost-effectiveness of the Intervention and (2) the initial effectiveness of reducing parental and teacher violence will be tested. To this end, a mixed-methods two-arm school-based pilot cluster-randomized controlled trial (CRCT) in Tanzania will be conducted.
One unique and novel aspect of this project is to test a school-based intervention approach that targets both teachers and parents. A school-based approach including both teachers and parents has the following key advantages: (1) parents of different social, economic, and educational backgrounds can be motivated to participate and (2) using the existing infrastructure of schools reduces costs and will later improve the scalability of the program. The project is bringing together the global health, development economy, and psychological perspectives to promote our collaboration within the German global health community and with research and policy partners in Tanzania.
- Detailed Description
The study is a two-arm cluster-randomized controlled trial with 16 primary schools (clusters) in the Urban District of Morogoro in Eastern Tanzania as level of randomization. The eligible schools are located in 20 wards (smallest administrative unit). To avoid cross-over effects between the study conditions, only one school per ward will be selected. To select the final sample of schools, 16 out of the 20 wards schools will be randomly selected and then one school from each ward. Then pairs of schools will be randomly formed. These has primarily logistical reasons: Due to the short project period (12 months), the implementation of the intervention will start after completion of the baseline assessment in the first pair of schools and after randomly allocation of the first school to the intervention condition. The selection and allocation of the schools will be performed by an independent researcher neither belonging to the core research team nor involved in data collection process.
At each school, 45 students in the in 5th school grade, 90 parents (45 mothers \& 45 fathers = 90 parents) and 25 teacher will be recruited. Thus the final sample will comprise 720 students, 720 parent pairs (720 mothers \& 720 fathers) and 400 teachers at baseline across 16 schools.
The study will have two data assessment points: baseline assessment prior to the intervention, the one follow-up assessment three months after the intervention. In addition, feasibility data will be assessed in the intervention group at the beginning and the end of the intervention. The cluster-randomized control trails will additionally be accompanied by a process evaluation.Qualitative information will be collected after intervention training of parents and teachers to complement the quantitative data.
Primary outcome measures are student-, parents- and teacher-reported physical and emotional violence by the parents or teachers in the past week. Secondary outcome measures include adult-child relationship, children's emotional and behavioral problems, quality of life, parents' and teachers' stress level and school climate.

Group Intervention Description ICC-T & ICC-P Interaction Competencies with Children ICC-T: 5 days with 8 hours of training for teachers. Core training components include teacher-student interaction, maltreatment prevention, effective discipline strategies, identifying and supporting burdened students and implementation of the training materials into the school setting. ICC-P: 4 days with 8 hours of training for parents. Core training components include parents-student interaction, maltreatment prevention, effective discipline strategies, identifying and supporting burdened children and implementation of the training materials into the daily home setting
- Primary Outcome Measures
Name Time Method Reduction of parents' or teachers' use of emotional and physical violence The CTS will be used at T1 (baseline, prior to intervention) and T2 (follow-up, 3 months after intervention) The Conflict Tactics Scale (CTS) will be used to assess parents' and teachers' use of emotional and physical violent discipline measures against children in the past week. Higher scores indicate higher levels of violence that is used by parents or teachers. A stronger reduction of violence use by parents and teachers of the intervention group compared to the control group is hypothesized.
Reduction of children's exposure to emotional and physical violence by parents and teachers The CTS will be used at T1 (baseline, prior to intervention) and T2 (follow-up, 3 months after intervention) The Conflict Tactics Scale (CTS) will be used to assess children's self-reported experiences of emotional and physical violence by parents at home and teachers at school in the past week. Higher scores indicate higher levels of violence that is used by parents or teachers. A stronger reduction of exposure to violence in the children of parents and teachers of the intervention group compared to the control group is hypothesized.
- Secondary Outcome Measures
Name Time Method Improvement of children's mental health The PSC-Y will be used at T1 (baseline, prior to intervention) and T2 (first follow-up, 3 months after intervention) The Pediatric Symptom Checklist - Youth Report (PSC-Y) will assess children's emotional and behavioral problems reported by children and parents. Higher scores indicate higher levels of children's mental health problems. A stronger improvement of mental health problems in the children of parents and teachers of the intervention group compared to the control group is hypothesized.
Increase of children's quality of life The KIDSCREEN-10 will be used at T1 (baseline, prior to intervention) and T2 (follow-up, 3 months after intervention) The KIDSCREEN-10 will assess children's quality of life reported by children and parents. Higher scores indicate higher levels of children's quality of life. A stronger increase of quality of life in the children of parents and teachers of the intervention group compared to the control group is hypothesized.
Change of parents' and teachers' attitudes towards emotional and physical violence The adapted version of CTS will be used at T1 (baseline, prior to intervention) and T2 (follow-up, 3 months after intervention) Teachers' and parents' attitudes towards emotional and physical violence will be assessed with an adapted version of the Conflict Tactic Scale (CTS). Higher scores indicate higher levels of positive attitudes towards violence. A stronger reduction of favourable attitudes towards violence of parents and teachers of the intervention group compared to the control group is hypothesized.
Improvement of school climate The Teacher Relationship with Colleagues will be used at T1 (baseline, prior to intervention) and T2 (follow-up, 3 months after intervention) The Teacher Relationship with Colleagues will assess school climate reported by teachers. Higher scores indicate higher quality of school climate. A stronger increase of school climate quality in the intervention group compared to the control group is hypothesized.
