Using a quasi-experimental design, this study examined how delivering a bri
ef training to volunteers in church congregations impacted (a) church volun
teers' persistence in delivering HIV antibody testing messages over time an
d (b) HIV antibody testing. behavior of the church volunteers themselves. C
hurch volunteers attended a briefing regarding delivery of public health me
ssages to others and the churches were assigned to either: (a) a trained co
ndition, when 345 volunteers received an additional 3-hour training in diff
using HIV prevention messages, or (b) a comparison condition, where 199 vol
unteers received no Hn I-specific training Three months after the intervent
ion, church volunteers in the HIV-trained condition reported delivering an
HIV antibody testing and prevention message to mo,a community members than
volunteers in the comparison condition. Those In the HIV-trained condition
also reported significantly higher levels of comfort and self-efficiency in
delivering HIV prevention messages than volunteers in the comparison condi
tion. However, the trained volunteers did not themselves get tested for HIV
at higher rates than the untrained volunteers. Training church volunteers
for community diffusion of HIV prevention message is an efficient strategy
for diffusing HIV messages. (C) 2001 John Wiley & Sons, Inc.
