The costs of implementation were calculated retrospectively and models of costs at scale estimated, from the perspective of the programme provider. Cost-effectiveness analysis considers both the cost per incident of abuse averted, and cost per disability-adjusted life year averted. Potential economic benefits from the societal perspective were estimated by developing a framework of possible savings.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The total implementation cost for Sinovuyo Teen over the duration of the trial was US$135 954, or US$504 per family enrolled. Among the 270 families in the treatment group, an estimated 73 incidents of physical and emotional abuse were averted (95%\u2009CI 29 to 118 incidents averted). During the trial, the total cost per incident of physical or emotional abuse averted was US$1837, which is likely to decrease to approximately US$972 if implemented at scale. By comparison, the economic benefits of averting abuse in South Africa are large with an estimated lifetime saving of US$2724 minimum per case.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Parenting programmes are a cost-effective intervention to prevent the abuse of adolescents by their caregivers in South Africa, when compared with existing violence prevention programmes and cost-effectiveness thresholds based on GDP per capita.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjgh-2018-001147","type":"journal-article","created":{"date-parts":[[2019,5,9]],"date-time":"2019-05-09T08:33:34Z","timestamp":1557390814000},"page":"e001147","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":20,"title":["Cost and cost-effectiveness of a parenting programme to prevent violence against adolescents in South Africa"],"prefix":"10.1136","volume":"4","author":[{"given":"Alice","family":"Redfern","sequence":"first","affiliation":[{"name":"Social Policy and Intervention, University of Oxford, Oxford, UK"},{"name":"IDinsight, Nairobi, Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucie D","family":"Cluver","sequence":"additional","affiliation":[{"name":"Social Policy and Intervention, University of Oxford, Oxford, UK"},{"name":"Psychiatry and Mental Health, University of Cape Town, Cape Town, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marisa","family":"Casale","sequence":"additional","affiliation":[{"name":"Social Policy and Intervention, University of Oxford, Oxford, UK"},{"name":"School of Public Health, University of Western Cape, Cape Town, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janina I","family":"Steinert","sequence":"additional","affiliation":[{"name":"Social Policy and Intervention, University of Oxford, Oxford, UK"},{"name":"Department of Economics, Georg-August-Universitat Gottingen, Gottingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,5,9]]},"reference":[{"key":"2025072914071306000_4.3.e001147.1","doi-asserted-by":"crossref","unstructured":"Hillis S , Mercy J , Amobi A , et al .
