^a Of the 965 participants, only one participant did not have data on internalized stigma, and 50 did not have data on ART adherence at T3. Participants with data on ART adherence at T3 who were included in the analysis (n=914) did not differ from 50 participants who did not have data on ART adherence at T3 on internalized stigma or any of the covariates (all p values > .19) and listwise deletion was used in analyses.

^b Associations with binary variables are also reported as correlation coefficients instead of t-tests in order to simplify presentation. Note that a t test and a correlation test yield the same p value.

^c Estimates adjusted for all other T1 predictors listed in the table, except for depression symptoms, which was entered in the mediation analysis.

^d Region: US South/Southeast versus Other US Regions.
