Note:
a
Screening for inclusion criteria was conducted at the clinic when the young women were approached about the study. If eligible and interested, they were then scheduled to come back at a later date for the baseline visit/intervention session (which was typically within a month for most participants, but could have been longer). Thus, these young women, because of the later date of the actual baseline visit, could have screened eligible yet then reported no unprotected sex acts in the past 6 months.
b
for the outcome variable reinfection across 36 month follow-up the n = 556.
