The Symptom Burden Score is an expanded version of the 20-item HIV symptom index. The score is calculated for the 28 most common symptoms in persons living with HIV. Each symptom is given a score ranging from 0 to 4 with the scores indicating the following: 0 (not experienced) , 1 (It doesn't bother me), 2 (It bothers me a little), 3 (It bothers me), or 4 (It bothers me a lot). The higher the score (closer to 4), the greater the symptom burden (worse outcome).

The PROMIS-29 includes seven health related quality of life domains (Physical Functioning, Anxiety, Depression, Fatigue, Sleep Disturbance, Social Functioning, and Pain), and the pain domain has two subdomains (interference and intensity). Each of the 7 domains has four 5-level items (i.e., 16 decrements each). In addition to these items, pain intensity is assessed using a single 11-point numeric rating scale anchored between no pain (0) and worse imaginable pain. Raw scores, except pain intensity, are transformed using the T-score metric based on the item response theory calibrations in which scores have a mean of 50 and standard deviation of 10 for the general population in the US. T-scores can be estimated using scoring tables listed in the PROMIS manuals. A higher PROMIS T-score implies more of the concept being measured; i.e., a higher PROMIS score on physical function indicates better functioning, whereas a higher score on depression indicates more severe depressive symptoms.

12-Item Medical Outcomes Study Short Form (SF-12) is a health survey to measure health-related quality of life.

Engagement with Health Care Provide scale is a 13-item scale in which subjects rate their interactions with their health care providers on a four-point scale with 1=always true and 4=never true. A total score can be calculated to create a possible range of 13-52. A low score (closer to 13) indicates greater provider engagement between the patient and provider.

The Visual Analogue Scale (VAS) measures adherence to antiretroviral therapy (ART). VAS asks subjects to indicate a point on a line that shows their best guess about how much of each drug they have taken. 0% means they have taken no drug, 50% means they have taken half their drugs, and 100% means they have taken every single dose.

Fried's frailty phenotype is a combination of five scores: weight loss in the last year, exhaustion, physical activity, walk time for a 15 foot interval, and grip strength. The frailty condition is defined as meeting the definition of frailty for at least 3 of the listed scores.
