School-based Prevention of Teacher Violence Against Children: A Cluster-randomized Controlled Trial in Zambia (ICC-T Zambia)
The United Nations Conventions on the Rights of the Child UN General Assembly, 1989), outlawed violence against children worldwide. Yet, 75% of all children worldwide - experience violence while growing up (Know Violence in Childhood, 2017). In Low- and Middle-Income countries prevalence rates at home and at school are higher (Hoeffler, 2017), with particularly high rates in Africa (Hecker et al., 2018; Nkuba, Hermenau, & Hecker, 2018; Hillis et al., 2016). Violence against children is related to negative mental health outcomes, lower quality in the child-adult relationship, lower cognitive functioning, and emotional and behavioural problems that begin in childhood and may persist through adolescence until adulthood (Berlin et al., 2009; Gershoff & Grogan-Kaylor, 2016; Hecker et al., 2016; Kim & Cicchetti, 2010; Majer et al., 2010; Mills et al., 2011; Newbury et al., 2018; Wilson et al., 2009).
The present study focuses on violent discipline in schools, as (1) many children are subjected to violent discipline at school on a regular basis, and (2) teachers justify violent discipline since they want to encourage better academic performance and maintain children's discipline (Masath et al., 2022). As in other African countries (Hecker et al., 2018; Nkuba, Hermenau, & Hecker, 2018; Hillis et al., 2016), violent discipline is prevalent in Zambian schools, despite its prohibition in 2022 (End Corporal Punishment, 2025).
With this study we test the intervention Interaction Competencies with Children - for Teachers (ICC-T; Kirika & Hecker, 2022) to alleviate violence against children. ICC-T is a manualised 5,5 days training workshop focusing on the basic competencies in the work with children, including non-violent action alternatives. Previous cluster randomized controlled trail studies on ICC-T in Tanzania and Uganda showed that teachers who participated in ICC-T, used significantly less violent discipline measures against children compared to teachers in the control group. The transferability of the intervention to and the effectiveness in the Zambian context remains unclear. Evidence from our research may guide policy makers to implement further measures aiming at ending violence against children.

상세 설명
We will use a two-armed school-based CRCT including up to 30 primary schools in the Eastern Province of Zambia (Petauke and Lusangazi). The schools will be combined into 12 school clusters, 6 of the 12 school clusters will be randomly allocated to the intervention group, which will receive the ICC-T workshop, and the remaining schools will be allocated to the control group without any intervention. The study will include two data collection phases: (1) a baseline assessment before the intervention allocation, and (2) a follow-up assessment approximately six months after the allocation and delivery of the intervention.
The study will begin with the baseline assessment involving teachers and students in all schools (May-July 2026). Then the intervention period, follows during school holidays (August 2026). The intervention will involve the Interaction Competencies with Children - for Teachers (ICC-T). Teachers from the selected schools will be trained in ICC-T on 5,5 days consecutively. A local team of ICC-T trainers, trained extensively by our research team, will implement the interventions. Also, all training will take place within school premises. A follow-up assessment with teachers and students will be conducted at all schools approximately six months after the intervention.
Approximately 30-35 randomly selected students from the third year of formal schooling per school cluster will be invited to participate. In addition, 20 to 25 teachers per school cluster will be invited to participate in the present study. This results in a baseline sample size of approximately 400 students and approximately 300 teachers across the 12 school clusters.
Primary outcome measures are student-, and teacher-reported physical and emotional violence by the teachers in the past week. Secondary outcome measures include adult-child relationship quality, attitudes and norms towards violence, children's emotional and behavioral problems, quality of life, peer victimization, teachers' and children's stress level, teachers empathy change in perspective and self-efficacy.
