The protocol did not specify type of contact expected (individual or group sessions) during months 13-48 nor for months 49-96; total contact was the only parameter specified. Optional group sessions were offered at least monthly and individual sessions could be scheduled at the request of participants. One campaign and one refresher were conducted annually and could be administered by either group or individual sessions, depending upon participant preference.
