Framing optional genetic testing in the context of mandatory newborn screening tests

چکیده
BACKGROUND Parents are increasingly faced with decisions about optional newborn bloodspot screening (NBS) despite no consistent policy for communicating information about such testing. We examined whether framing optional NBS alongside mandatory NBS influenced intention to participate in optional NBS. METHODS For this Internet-administered study, 2,991 adults read a hypothetical vignette in which optional NBS for Duchenne muscular dystrophy (DMD) was either presented by itself (in isolation), alongside a description including the total number of mandatory NBS tests ("bundled" mandatory context), or alongside a listing of each mandatory NBS test ("unbundled" mandatory context). We assessed associations with participants' intended participation using ordered logistic regression models, and associations with attitudes towards optional DMD NBS and subjective norms using Analysis of Variance. RESULTS Participants were more likely to choose optional DMD NBS if they also read information about mandatory NBS (either bundled or unbundled) versus when DMD NBS was presented in isolation. Participants who read about optional DMD NBS in isolation also reported such testing to be less important and that they would worry more about the results than those who also saw mandatory NBS information. CONCLUSIONS Future NBS programs should pay attention to the framing of optional testing communication, as it influences parental behavior. Predictors of NBS uptake will become increasingly important as NBS programs continue expanding.
