Bracha and Hayashi appear eager to challenge the conclusions of our March 2007 article1 because of “major methodological and conceptual limitations that severely limit its generalizability.” Linkage sampling might have its problems but these do not necessarily invalidate the results. The study conclusion that “physical” and “nonphysical”
stressors show substantial overlap in their immediate impact needs no statistical analysis; the data presented in Table 1 of our article1 speak for themselves. In addition, linkage sampling does not characterize the whole sample; the 102 Belgrade site participants were mostly consecutively recruited from 2 associations for war veterans and prisoners of war. The results based on this subgroup do not present a different picture.
