| Sumario: | Issue Elderly individuals who wish to remain independent can benefit from carefully designed information and communication technology (ICT) systems to maintain social connectivity and well-being. We describe initial results from the PRISM clinical field trial which employs an internet- connected computer system designed in accordance with principles of user-centered design. Three hundred participants age 64+ years who were living alone and at risk for social isolation were randomized, half to the computer system and half to a paper-based (binder) control condition that provided similar information and social contact. Content We describe the goals for PRISM, its structure and components, and the process of recruiting a diverse sample from three regions in the U.S.A., as well as early positive outcomes of reduced social isolation and improved social connectivity (S.J. Czaja); we outline the use of focus group methodology and questionnaires to select PRISM features and the iterative design process used to create the hardware, software, and training components for the PRISM system (W.A. Rogers); we detail the development of one of our measurement scales, the Computer Proficiency Questionnaire, and discuss early results indicating the effectiveness of PRISM in promoting computer proficiency (W.R. Boot). Our discussant (H. Umemuro), an expert on designing ICT systems for older adults, will provide his perspectives on PRISM. Structure There will be four oral presentations, including commentary, followed by a panel discussion. Conclusion The PRISM clinical trial indicates that the risk of social isolation for older adults can be reduced and social connectivity for the elderly improved by careful design of ICT systems and of training packages based on principles of human factors and through an iterative design process. A system such as PRISM, which fits the gerontechnology matrix as an example of the intersection of ergonomics design and psychology1, can advance the goal of promoting successful longevity in an aging population.
