Brief summary
The present study investigates the feasibility of working memory training in people aging with HIV (PAWHIV). In a cross-over design this stage 1 feasibility trial, will evaluate acceptability, and estimate possible effect sizes related to working memory training by examining potential differential effects in PAWHIV and those aging without HIV. This project highlights the importance of tailored cognitive assessments and interventions, engaging with underrepresented communities to enhance inclusivity in cognitive health research.
Detailed description
In a randomized controlled trial (RCT) with a 3x2 design (pre-test, post-test, follow-up; PAWHIV, people aging without HIV), we will evaluate feasibility of implementing working memory-based interventions in PAWHIV. This study will examine the differential effects of WM training between PAWHIV and aging adults without HIV, providing insight into specific cognitive challenges in PAWHIV that may influence the efficacy of cognitive training interventions. The results of this trial will be instrumental in developing targeted, evidence-based interventions that promote cognitive health for PAWHIV and contribute to the broader understanding of cognitive aging in vulnerable populations. Relying on an extended battery of cognitive assessments, we will test different multivariate models to best capture the unique cognitive profiles of PAWHIV and how they compare with people aging without HIV. This analytical framework will allow us to gain insight into and better addressing the needs of the PAWHIV community The cross-over trial will obtain within-subject comparisons of training with enriched (game-like) versions of working memory training tasks compared to basic (non-gamified) versions of these tasks. Participants are assigned to Non-Gamified Span training and Gamified Span training for a total of 50 sessions per participant: the first few sessions consist of completing questionnaires and computerized cognitive assessments (pre-test). Participants then complete 20 sessions of working memory training. After a mid-test, they complete 20 sessions of a different type of working memory training. Post-test is administered upon training completion, and at least a month later, participants complete 3 follow-up sessions.
Interventions
BEHAVIORALSpan
The training program is a personal device-based adaptive version of a visual working memory span task, either devoid of game elements or embedded in a gamified platform game

Intervention model description
A randomized crossover trial will be conducted and participants will be randomly assigned to 1 of 2 conditions: Condition 1 consists of training type 1 followed by training type 2, whereas Condition 2 consists of training type 2 followed by training type 1. They will be assigned to Non-Gamified Span training and Gamified Span training.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Everyday Memory Questionnaire Revised | Day 24, Day 46, Day 77 | The Everyday Memory Questionnaire Revised (Royle \& Lincoln, 2008) consists of 13 items that describe everyday events that might involve forgetting. Participants are asked how often on average they think each one has happened to them over the past month on a 5-point scale (0-4) and the total score is calculated as the sum of all responses. The minimum total score is 0 and the maximum is 52, with higher scores indicative of greater presence of memory difficulties. The outcome measure is the change in total score at the point of measurement compared to baseline at Day 1. |
| Change in General Cognitive Ability Composite Score | Day 77 | A composite score will be generated by taking the average of standardized outcome measures on tasks in the Standard Older Adult Cognitive Battery (SOACB), which consists of word list learning, complex figure copy, object naming, trail making, a vocabulary task, and matrix reasoning. The outcome measure is the change in the composite score reached on the task compared to baseline at Day 1. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Inhibitory Control Composite Score | Day 24, Day 46, Day 78 | The score is the mean of standardized dependent variables on tablet-based inhibitory control tasks. The outcome measure is the change in the composite score at the point of measurement compared to baseline at Day 2. |
| Training Experience Enjoyment | Day 24, Day 46 | Scores range from 1 to 5, with higher scores indicative of greater enjoyment of the training task enjoyment, subjective progress, and satisfaction of the training task |
| Training Experience Subjective Progress | Day 24, Day 46 | Scores range from 1 to 5, with higher scores indicative of greater subjective of the training task progress. |
| Training Experience Satisfaction Scale | Day 24, Day 46 | Scores range from 1 to 5, with higher scores indicative of greater satisfaction of the training task. |
| Training Experience Difficulty Scale | Day 24, Day 46 | Scores range from 1 to 10, with scores 1-3 indicating that the training was too easy, scores 4-7 indicating that the training was of appropriate difficulty, and scores 8-10 indicating that it was too difficult. |
| Exit Survey | Time Frame: Day 79 | Participants are asked 5 open-ended questions about their subjective experience of participating in the study. |
