1
P-value is for the Intervention Group vs. Control Group difference derived from regressing the variable on group and is based on robust standard errors calculated to accommodate clustering by friendship group (as defined by the index case). Dichotomous variables required logistic regression instead of linear regression.
2
% worried or very worried
3
The condom attitude items were inadvertently excluded from the pre-intervention instrument administered to 33 intervention Group participants.
4
% always use condoms
5
% somewhat likely or very likely
