Furthermore, studies conducted so far on the experience of thrombophilia screening have focused only on the lived experience of patients who received a positive outcome to the genetic test (Moore, Norman, Harris, & Makris, 2008 ), whereas previous studies on other issues have shown the importance of considering the psychological and behavioral effects of a negative result; for example, in cardiovascular risk (Nielsen et al, 2009 ) or the genetic test for familial adenomatous polyposis (Michie et al, 2002 ).
