Note. HIV = HIV-risk reduction condition (n = 123); CTL = standard care control condition (n = 110). Positive regression coefficients indicate increase, negative coefficients indicate decrease over time. The p values for Condition × Time interaction effects reflect one-tailed values for beta coefficients that show the hypothesized change. Est. = estimate.
