description	The objective of this study was to examine the extent to which caregivers can be used to provide proxy responses for dementia clients in a study on the acceptance of GPS technology. Methods: Forty-five client–caregiver dyads used one of three GPS devices. The Unified Theory of Acceptance and Use of Technology (UTAUT) was used to create two questionnaires, one for dementia clients and one for caregivers, as proxies. Spearman rho bivariate correlations of responses for each UTAUT construct were used to compare the client and caregiver responses post-usage of the GPS devices. Results: The mean age of the clients was 76.02 years (SD = 11.5). Overall, after using the GPS devices, the responses of the clients and caregivers were correlated and statistically significant (rxy Overall summative scale = 0.550). In addition, 4 out of 6 constructs of the UTAUT were correlated and statistically significant (p < 0.05) (rxy Performance Expectancy = 0.160; rxy Social Influence = 0.478; rxy Behavioural Intention to Use = 0.347; and rxy Actual Use = 0.570). Conclusion: The degree of agreement between the caregivers and clients, especially for the constructs intention to use and actual use of the GPS technology, suggested that caregivers can respond on behalf of dementia clients on technology acceptance questionnaires.

Métodos: Cuarenta y cinco díadas cliente-cuidador utilizaron uno de los tres dispositivos GPS. Se utilizó la Teoría Unificada de Aceptación y Uso de la Tecnología (UTAUT) para crear dos cuestionarios, uno para los clientes con demencia y otro para los cuidadores, como sustitutos. Se utilizaron correlaciones bivariadas de Spearman rho de las respuestas para cada constructo de la UTAUT para comparar las respuestas de los clientes y los cuidadores tras el uso de los dispositivos GPS. Resultados: La edad media de los clientes era de 76,02 años (SD = 11,5). En general, tras el uso de los dispositivos GPS, las respuestas de los clientes y los cuidadores estaban correlacionadas y eran estadísticamente significativas (rxy escala sumativa global = 0,550). Además, 4 de los 6 constructos de la UTAUT estaban correlacionados y eran estadísticamente significativos (p < 0,05) (rxy Expectativa de rendimiento = 0,160; rxy Influencia social = 0,478; rxy Intención de comportamiento de uso = 0,347; y rxy Uso real = 0,570). Conclusiones: El grado de acuerdo entre los cuidadores y los clientes, especialmente para los constructos intención de uso y uso real de la tecnología GPS, sugiere que los cuidadores pueden responder en nombre de los clientes con demencia en los cuestionarios de aceptación de la tecnología.application/pdfengTaylor y Francis Ltd.Colombiahttps://www.tandfonline.com/doi/abs/10.1080/0144929X.2018.1470672Caregivers as a proxy for responses of dementia clients in a GPS technology acceptance studyArtículo de revistainfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85Behaviour & Information Technology Volume 37, 2018 - Issue 6645663437N/ABehaviour '&' Information TechnologyADI (Alzheimer’s disease international). 2014.
