Abstract

fetched live from OpenAlex

Advancements in treatment have resulted in improved survival among people living with HIV. In order to prepare for the aging of the HIV population and support healthy aging among those living with HIV, it is important to understand what allows some individuals to age well, but not others. Recognizing the need for a measurement tool that can help discriminate between degrees of healthy aging among persons aging with HIV, I set out to evaluate a candidate instrument – the Healthy Aging Score. While the tool seems to possess evidence of face, and construct validity, there were inconsistent findings with regards to its content validity. To account for this, the Healthy Aging Score may need to be used in conjunction with other measurement tools such as those assessing stigma, enjoyment of life and mental health to adequately capture what healthy aging means to those living with HIV.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
