14 questions pertaining to HIV-related knowledge were developed according to the information that will be included in the intervention. Participants will receive one point for each correct answer and then the scores for each question will be summed to obtain a final score. Therefore, the minimum score will be 0 and maximum score will be 14 where the scores closer to 14 indicate patients have more HIV-related knowledge

Satisfaction with provider was measured with the Overall Satisfaction with Provider and Clinic scale published by Dang et al., 2016. We asked a selection of questions from this scale based on their appropriateness for our study. The questions asked and the range of possible scores are as follows. Question 1: 1 - 7 Question 2: 1 - 10 Question 3: 1 - 7 Question 4: 1 - 5 Total scores are then calculated by adding participant responses on each of the four questions. The total possible score range for the questions asked from this scale was 4 - 29, with higher scores indicating more satisfaction with HIV provider.

The Self#Efficacy for Managing Chronic Disease (SEMCD) scale is a 6#item questionnaire that measures confidence in one's ability to manage fatigue, pain, emotional distress, and other symptoms using self#management techniques. Each item is scored from a minimum value of 1 which indicates "not at all confident" to a maximum score of 10, which indicates "completely confident." Final scores are calculated as the mean of the 6 questions ranging from 1(minimum) to 10 (maximum), where higher scores indicate higher self-efficacy (better outcome).

We measured adherence to prescribed antiretroviral therapy with the validated simplified medication adherence questionnaire (SMAQ) (Knobel 2002). This is a 6- item questionnaire that measures medication adherence. There is no minimum or maximum score on this scale. Participants are considered either "adherent" (better outcome) or "non-adherent" (worse outcome) based on their responses to these 6 questions. They are considered "non-adherent" if they answer "yes" to questions 1, 2, 3, OR 5, regardless of their answers on the other questions. Participants are also considered "non-adherent" when they indicate that they have missed more than two doses of their medication in the past week (response to question 4), or over 2 days of total non-medication during the past 3 months (response on question 6).

Satisfaction with clinic was measured with a selection of questions from the Overall Satisfaction with Provider and Clinic scale published by Dang et al., 2016. To assess satisfaction with the clinics, we asked a selection of questions from this scale based on their appropriateness for our study. The included questions and the associated range of possible scores are as follows. Question 7: 1 - 7 points possible Question 8: 1 - 7 points possible Question 9: 1 - 5 points possible Total scores are then calculated by adding participant responses on each of the three questions. The total possible score range for the questions asked from this scale was 3 - 19, with higher scores indicating more satisfaction with the clinic.

A second measure of health literacy, the Newest Vital Sign (NVS) will also be administered. Scores on this scale range from 0-6 where a score of 0-1 suggests high likelihood of limited literacy, a score of 2-3 indicates the possibility of limited literacy, and a score of 4-6 almost always indicates adequate literacy.

The Brief Acculturation Rating Scale for Mexican Americans- II (ARMSA-II) is a 12-item scale that measures acculturation with 6 items from the AOS (Anglo Oriented Scale) of the ARSMA-II and 6 items from the MOS (Mexican Oriented Scale) (Bauman 2005). Responses are collected with Likert-type questions on which the scores range from 1 (not at all) to 5 (almost always/extremely often) on each item. The ARMSA-II has been used in Mexican Americans as well as other Latino subgroups, including Dominicans. Scores are calculated by summing the scores on each of the six item subscales and then dividing by 12 to get a mean acculturation score. Therefore, the possible range of scores is 1-5 with higher scores indicating greater acculturation. Note: The scale was only administered to participants who were not born in the country where data collection took place.
