Participant Flow

Of the 124 participants who signed informed consent, 3 were excluded due to ineligible or unfeasible participation. 121 participants were randomly assigned to either the control or intervention (Gender Affirming Abriendo Puertas) group. 18 providers/staff were also enrolled as secondary participants for focus groups (not randomized and did not receive an intervention). Total = 139. This was not a cluster-randomized study.

Population: All collected data are reported; however, data collection was restricted to participants who were currently receiving antiretroviral therapy (ART) at Month 6, due to outcome-specific question design assessing only those on ART at the time of evaluation. Accordingly, the number of participants included in this analysis may differ from outcomes assessing all participants.

Participants currently on antiretroviral therapy will be asked: "During the last 4 days, how many days did you not take your entire antiretroviral therapy dose?" Response options are 0 = No antiretroviral therapy interruption (i.e., Adherent) and \>0 = Antiretroviral therapy interruption (i.e., Non-Adherent).

Participants who reported ever having taken antiretroviral therapy will be asked: "In the past 6 months, have you stopped or suspended your antiretrovirals?" Response options are No = No antiretroviral therapy interruption (Adherent) and Yes = Antiretroviral therapy interruption (Non-Adherent).

The Patient Health Questionnaire (PHQ-9) is a 9-item screener to assess the frequency of depressed mood/anhedonia over the past two weeks. Participants respond to how often they have been bothered by symptoms, from 0 (not at all) to 3 (nearly every day). Scores range from 0-27, with higher scores suggestive of greater depression. Per protocol 0-9=No depressive symptoms; 10-27=depressive symptoms.

The Hospital Anxiety and Depression Scale (HADS) is a 14-item questionnaire that includes two 7-item subscales assessing anxiety (HADS-A) and depression (HADS-D), each rated on a 0-3 scale. For this study only HADS-A subscale was used. Raw scores range from 0-21 with higher scores indicating higher anxiety. Per protocol, scores from 0-7 = no anxiety symptoms, scores from 8-21 = anxiety symptoms.
