Using an online survey completed by 674 university students and academic staff in South Africa, we elicited attitudes towards the return of SFs.  The majority of survey respondents (80%) indicated that research participants should be given the option of deciding whether to have genetic SFs returned. 
Survey
Latent class analysis (LCA) was performed to classify sub-groups of participants according to their overall attitudes to returning SFs.
