p < .001. Pairwise comparisons of estimated marginal means were used to indicate significant differences within rows at p < .05: Anxiety (a > c, d; b > c, d; c > d), Depression (a > c, d; b > c, d), and Self-efficacy for Condom Use (a < d; b < c, d). Fisher’s exact test was used to test for significant within row differences in Medication Adherence: a, b > d.
