In 2018, the Centre for Trust, Peace and Social Relations (CTPSR) at Coventry University was contracted by World Vision to conduct three in-depth, qualitative analyses of Celebrating Families, focusing on implementation in Afghanistan, Myanmar and Tanzania. These were commissioned to build the evidence base for understanding how Celebrating Families is effective in supporting parents and caregivers to develop nurturing environments for children. Data collection for the Afghanistan and Myanmar case studies took place in July and August 2018 led by Research Fellow Laura Payne. The data collection for the Tanzanian case study took place in May 2019, led by Professor Hazel Barrett with Dr Pascal Niyonkuru. The data was collected using qualitative methods, including individual interviews, focus groups and an arts-based workshop with children. A total of 338 children, parents, faith and community leaders, child protection personnel and World Vision staff took part across the three countries.
