    Cognitive remediation group therapy compared to mutual aid group therapy for people aging with HIV-associated neurocognitive disorder: randomized, controlled trial
    (Taylor and Francis Group, 2021-08-21) Eaton, Andrew D.; Craig, Shelley L.; Rourke, Sean B.; Sota, Teresa; McCullagh, John W.; Fallon, Barbara A.; Walmsley, Sharon L.
    Cognitive impairment is an important comorbidity for people aging with HIV, and group therapy may ameliorate the associated anxiety and stress. Combination psychosocial interventions may have better outcomes than single technique approaches. A pilot, parallel design, two-arm trial randomized people aging with HIV-Associated Neurocognitive Disorder (HAND) to Cognitive Remediation Group Therapy (Experimental; combination of brain training activities and mindfulness-based stress reduction) or Mutual Aid Group Therapy (Control). Outcomes were feasibility, acceptability, fidelity, and exploratory measures of anxiety, stress, coping, and use of mindfulness and brain training activities. Amongst forty contacted participants, 15 replied, 12 recruited, and 10 completed. Assessors confirmed intervention delivery with satisfactory fidelity. The novel arm had statistically significant improvements in stress and mindfulness use compared to control, and brain training and mindfulness use sustained at 3-month follow-up. Requiring a HAND diagnosis made recruitment challenging. Further research should broaden eligibility to people aging with HIV and cognitive challenges.

    Exploring the Perspectives of Older Adults Living With HIV on Virtual Care: Qualitative Study
    (JMIR Publications Inc., 2024-12-04) Kokorelias, Kristina M.; Valentine, Dean; Dove, Erica; Brown, Paige; McKinlay, Stuart; Sheppard, Christine L.; Singh, Hardeep; Eaton, Andrew D.; Jamieson, Laura; Wasilewski, Marina B.; Zhabokritsky, Alice; Flanagan, Ashley; Abdelhalim, Reham; Zewude, Rahel; Parpia, Rabea; Walmsley, Sharon L.; Sirisegaram, Luxey
    Background As the population of individuals with HIV ages rapidly due to advancements in antiretroviral therapy, virtual care has become an increasingly vital component in managing their complex health needs. However, little is known about perceptions of care among older adults living with HIV. Objective This study aimed to understand the perceptions of older adults living with HIV regarding care. Methods Using an interpretive, qualitative, descriptive methodology, semistructured interviews were conducted with 14 diverse older adults living with HIV. The participants lived in Ontario, Canada, self-identified as HIV-positive, and were aged 50 years or older. Efforts were made to recruit individuals with varying experience with health care. Reflexive thematic analysis was conducted with the interview transcripts to identify prevalent themes. Results The identified themes included (1) the importance of relationships in virtual care for older adults living with HIV; (2) privacy and confidentiality in virtual care; and (3) challenges and solutions related to access and technological barriers in virtual care. These themes highlight the perceptions of diverse older adults living with HIV concerning care, emphasizing the fundamental role of trust, privacy, and technology access. Conclusions By embracing the unique perspectives and experiences of this population, we can work toward building more inclusive and responsive health care systems that meet the needs of all individuals, regardless of age, HIV status, or other intersecting identities.

    Proof of concept for a multi-method approach to evaluate the usability of websites with public health content: The case of Alzheimer association websites
    (Canadian Psychological Association, 2022-10-06) Friedrich, Trista E.; Smith, Austen K.; Hunter, Paulette V.
    Methods for assessing usability are advancing rapidly, and include think-aloud protocols, objective measures such as task timing, and ultra-sensitive measures such as eye tracking and page recording. In this study, we provide proof-of-concept for the new, combined use of these three types of measures within a quasi-experimental paradigm focused on a question relevant to public health. The quasi-experiment specifically involved assessing the usability of four English-language Alzheimer websites from around the world (USA, UK, Ireland, Canada), all of which contained information about cognitive health. Participants completed two tasks; one requiring them to identify strategies to prevent dementia and another requiring them to locate a definition of Alzheimer’s disease. We hypothesized that the websites would have superior usability for the former task and inferior usability for the latter task. We also hypothesized positive correlations among eye tracking measures, simpler performance measures (e.g., task completion time), and subjective usability measures. We found that the new quasi-experimental protocol facilitated comparison of tasks and websites. It also facilitated interpretation by permitting comparison across measures. Overall, this study provides proof of concept for the use of this multi-method approach to evaluate the usability of websites. It also provides information that could potentially be used to advance further pilot or experimental hypothesis testing on this topic.
