School-based prevention of teacher and parental violence against children: Study protocol of a cluster-randomized controlled trial in Tanzania.

ABSTRACT

BACKGROUND: Violence against children at home and at school is particularly prevalent in Africa and is associated with adverse and persistent health effects on children. The violence prevention intervention Interaction Competencies with Children - for Teachers (ICC-T) is an effective tool to reduce violence against children by fostering teachers' non-violent communication and interaction skills. To enhance these effects, in the present study, ICC-T will be extended to parents (ICC-P) aiming to increase children's experience of consistent behavior and application of non-violent discipline strategies between teachers and parents. METHODS: To investigate the effectiveness of the school-based combined implementation of ICC-T and ICC-P, a cluster-randomized controlled trial with 16 primary schools in the urban district of Morogoro in Eastern Tanzania will be conducted. Both quantitative (structured interviews) and qualitative (focus group discussions, in-depth interviews, evaluation forms) methods will be used to investigate the effects on teachers' and parents' violence against children in home and school settings. The intervention implementation will be accompanied by a comprehensive process evaluation to assess the implementation quality of and participants' engagement with ICC-T and ICC-P. Potential downstream effects of violence reduction will be investigated by assessing the children's mental health and well-being. DISCUSSION: The present study aims to provide evidence for the feasibility, acceptability, and effectiveness of the school-based combined implementation of ICC-T and ICC-P to reduce teacher and parental violence against children and contribute to children's well-being in home and school settings.
