“…While compared with non-bereaved controls, they showed no confidence in the persons in their network any more (Farberow, Gallagher-Thompson, Gilewski, & Thompson, 1992b). Some researchers thought that persons who were close to the deceased were at heightened risk for complicated grief or other psychosocial consequences (Mitchell, Kim, Prigerson, & Mortimer-Stephens, 2004; Prigerson, Bierhals, Kasl, Reynolds, Shear, Day, et al, 1997; Scocco, Frasson, Costacurta, & Pavan, 2006), and the familial transmission of suicidal behavior had been demonstrated (Brent, Oquendo, Birmaher, Greenhill, Kolko, Stanley, et al, 2002; Melhem, Brebt, Ziegler, Iyengar, Kolko, Oquendo, et al, 2007). In this study, we want to know whether there are differences in attitudes toward suicide between the informants of suicides and the informants of living controls, between the family members of suicides and the family members of non-suicides, and between the family members of suicides and non-family members of suicides.…”
