To assure consistency
among groups, the leaders prepared a group process
plan and summarized, discussed, and clarified
the purpose and procedure of the group session
with observers at a preview meeting. Data were
collected at 1 week before the first group session,
at the fifth group session, the last group session,
and 2 weeks after the final session. Descriptive
statistics, 2 test, t test, and GEE, were used for
data analysis.
