Description of intervention(s) / exposure
The primary purpose of this study is to find out how much difficulty people living with HIV (PLHIV) who live in a regional area of Australia, have with everyday tasks, hobbies, sports, jobs, memory, emotion, or participating in social events. These difficulties are known as ‘Disability’ and ‘Frailty’, and we will measure them using three questionnaires. Also, because one of the disability questionnaires is relatively new, we want to compare it with the established disability questionnaire we are using, to test how suitable it is to use for PLHIV in regional Australia. The study will recruit 54 volunteers who are over 18 years old, living with HIV, and attend a Sexual Health Service. Knowing what difficulties PLHIV have will tell us what changes are needed in health and community services to improve their quality of life. This is important, as disability due to HIV leads to a reduced quality of life. So, without a better understanding of disability and frailty in PLHIV, the best services and funding to improve health, function, inclusion in society, and quality of life for this group of people.
This study is clinical health research. This is a cross-sectional study with a nested reliability and validity study. It uses quantitative methods, using self-reported written questionnaires to measure disability and frailty in community-dwelling people living with HIV. Participants will complete the T0 data collection at a face to face 'usual care' sexual health service appointment. T1 data which is completion of one questionnaire, will be conducted at a self selected location (likely to be at their home) prior to mailing back to the chief investigator.
Phase 1: Is a single centre cross-sectional study using self-reported questionnaires to measure disability using the World Health Organisation Disability Assessment Schedule (WHODAS 2.0) and frailty using the Frailty Scale with a single time point data collection per participant (T0). The Questionnaires will take approximately 35 minutes to complete all three.
Phase 2: Comprises a nested construct validity study evaluating the HDQ compared to the WHODAS 2.0 (comparative reference standard) and Frailty Scale, and a repeated measures reliability study of the HDQ when delivered at two time points seven days apart (T0 and T1).
Both Phase 1 and Phase 2 will consist of the same study population/participants.

Statistical methods / analysis
The number of people living with HIV (PLHIV) attending the study site is approximately 140. Based on previous studies which obtained Cronbach’s alpha of around 0.85 with a 95% CI width of approximately 0.15, a sample size of 54 was calculated based on Bonnett (2002). This sample size is based on test-retest of a single measurement instrument (HDQ) or comparing two measurement instruments (HDQ and WHODAS 2.0 or FS). Assuming a dropout of 20% this means approximately 65 participants should be recruited, which represents approximately 45% of PLHIV attending the study site. Descriptive analysis of the demographics of PLHIV will be undertaken, including mean and standard deviation, or median and inter-quartile range, as appropriate. Given the small population, it is unlikely that any sub-group analysis can be performed. WHODAS 2.0 and FS scores will be calculated and analysed in accordance with the measurement scales’ documentation.
A statistical model with the covariate antiretroviral (ART) regimes, length of time on the regimes, and demographic data will be built in relation to the frailty/disability scores (i.e. Frailty Scale (FS), WHODAS-2, HDQ). Where sufficient data is available individual ART regimes will be used, however if this is not possible, ART regimes will be grouped by those most similar. Alternatively, a cluster analysis of ART regimes and levels of frailty/disability as measured by the FS, WHODAS 2.0, HDQ could be undertaken to explore associations between ART regimes and frailty/disability scores.
Test-retest analysis of the HDQ data will be based on intraclass correlation coefficients (ICC) for consistency (equivalent to Cronbach’s a). Comparison of HDQ domain scores to WHODAAS 2.0 and FS domain scores will use ICCs for consistency (C,k) and absolute agreement (A,k). Data permitting, exploratory models may also be produced. Analysis will be conducted using Stata version 16.1 or above, and R 4.0 or above for modelling.
