    Consequences of caring for the physical health, mental health and subjective well-being of Chilean older adults
    (Policy Press, 2024) Fernandez, M. Beatriz; Miranda-Castillo, Claudia; Rosell Cisternas, Javiera Esperanza; Herrera Campos, Priscilla Soledad
    Using a propensity score matching approach, this study evaluates the effect of caring on the physical health, mental health and subjective well-being of Chilean older people. The average treatment effect was not significant in any of the outcomes to physical health. However, older carers - and those who care intensely - were more likely to have depressive and anxious symptomatology and lower life satisfaction than older non-carers. Interventions should consider strategies that favour mental health and avoid caregiver burden, considering the interaction between caring and the challenges of ageing. This could improve the quality of life of carers and those being cared for.

    Interaction and Design Barriers for Older Adults in Food Delivery Apps: A Usability Study
    (2024) Julia Nehme, María Begoña; Rosell Cisternas, Javiera Esperanza
    This study aims to evaluate the usability of two Food Delivery Apps (FDAs) available in the marketwith a sample of older adults. We performed a usability study of basic tasks required to purchasegroceries with 12 participants (Mage ¼ 70.92, SD ¼ 4.56). Results showed that interaction experi-ence with both apps was similar. Most participants could perform the tasks, but not efficiently.Tasks that took the longest mean time were adding the first product to the cart and schedulingthe delivery service. We found 22 interface barriers for FDA1 and 23 for FDA2. The most frequenterrors were caused by a lack of a clear roadmap to guide the purchase process, unclear feedbackwhen adding products, information overload, and difficulty distinguishing interactive buttons fromtext/icons and mandatory actions from optional ones. System Usability Scale results were belowthe suggested cut-off point of 68. We provide recommendations that could help design accessibleFDAs for older adults and make them easier to use for everyone
