Optimus Study

The Optimus Study is a cross-national initiative on child sexual victimization in the context of other forms of maltreatment, and aims to provide much-needed evidence on the risks and protective factors for children and youth. The study has so far been conducted in Switzerland, China, and South Africa. In Switzerland, it was a school-based epidemiological survey carried out in 2009-10, with almost 7’000 youth between 15-17 years of age.

The survey in Switzerland collected lifetime and previous-year prevalence of sexual victimization experiences for a nationally representative sample, as well as information on other types of maltreatment, risk factors, protective factors, and consequences of victimization.

The Chinese study included a household survey of 3’321 children age 15-17 and 8’945 parents of children age 0-17, as well as a school-based survey of 18’341 students age 15-17. Click here for more information about the Chinese datasets.
