::Both the pledge and nonpledge group had specifically not had intercourse as of the ''first'' survey. Pledgers did not have to be virgins at the time of the ''second'' survey in order to be included in the 'pledge' group - that group may (or may not) have included 'born-again' virgins. The study found that the behavior of the pledgers did not differ from that of the closely matched nonpledgers except insofar as the pledgers were less likely to use methods of pregnancy and STD prevention.

::It should also be noted that the pledgers and matched nonpledgers, combined, were more sexually conservative than the remaining 2506 students in the subsample - but this is to be expected. The mass-media reports of this study have unsurprisingly underemphasized that the study was comparing sexually conservative pledgers with sexually conservative non-pledgers, not with ''all'' nonpledgers.--[[User:Brossa|Brossa]] 23:11, 30 December 2008 (EST)
