The Impact of Design on Feelings of Trust of Online Information for Family Caregivers of People with Dementia

CARE-RATE is an online assistive-tool being created to support caregivers in searching for information that fits their individualized needs. As the use of the web for information continues to expand, the issue of how to trust online information is a key concern for caregivers of people with dementia. Several studies have been conducted exploring how website design affects trust, however, no work has been done for interface design for caregivers of people with dementia. This research explores what design features may significantly impact trust for family caregivers of people with dementia. 20 at-home caregivers will be asked to complete a set of search-based tasks through CARE-RATE. Half of the participants will be exposed to a standard search engine results page (SERP), while the other half will be given a SERP with additional information such as ratings from other caregivers, transparency of the author/organization, and images associated with the content. The data derived from this study will be consolidated into a modified Lens Model to further understand how cues impact source selection and trust and, subsequently, integrated into CARE-RATE's interface design.
