Purpose Adoptees are a population that could benefit from genetic testing to fill gaps in family health history (FHH). Elective genomic testing (EGT) provides adoptees with clinical genetic testing options to learn about genetic health risks in the absence of FHH. We assessed adoptees’ interests in, motivations for and perceived utility of EGT.
Methods Adult adoptees and non-adoptees completed an anonymous, online survey regarding their interest and motivations for EGT, perceived utility of potential results and willingness to pay for EGT. A validated measure of social identity was included to measure the effects of social identity on testing interest.
Results There were 112 adoptees and 229 non-adoptees included in the study. Adoptees reported greater interest in EGT (OR 5.0, 95% CI 2.2 to 11.3) than non-adoptees. They were motivated by curiosity and a desire to learn information about risks to children and grandchildren more than non-adoptees. Adoptees with higher education and non-adoptees with higher incomes were significantly more likely to spend more on EGT. Adoptees with higher incomes and non-adoptees with higher education were not significantly more likely to spend more. Social identity was a significant mediator between adoption and testing motivation.
Conclusion Understanding adoptees’ unique motivations and interests in EGT will allow healthcare providers to better address the informational needs and desires of this population. Social identity provides a foundation for recognising adoptees’ universal experiences that influence motivations for genetic testing.
