摘要

In two studies of fainting in Army blood donors: Data gathered on 172 donors showed no significant differences in intelligence or educational level between reactors and nonreactors. Data on 394 donors showed no significant differences between the two groups. Prephlebotomy data on over 1,000 donors showed no differences in systolic blood pressure between reactors and nonreactors. Though a significant downward shift in the pulse means occurred for both groups over observation periods, no significant differences between reactors and nonreactors were apparent in either study. A validation of an initial study of anxiety as assessed by a modification of the Taylor's MAS reversed our original findings of significant differences in anxiety between reactors and nonreactors. A significant rise in the postphlebotomy anxiety of nonreactors was demonstrated in the initial study. No further work was done on this change. Four of the 28 items of the Ruetz fainting scale held up to cross-validation. (Author)
