Notes: All instruments listed were measured at baseline, except for adherence, emergency room visits, and detectable VL, which were measured at both baseline (BL) and follow-up (FU). N = 264 for Study 1 baseline measures; N = 205 for Study 1 follow-up measures; N = 2848 for Study 2 baseline measures, and N = 232 for Study 2 follow-up measures.
