Exploring the relationship between computer proficiency and computer use over time in the PRISM trial

Abstract

The aim of the PRISM trial was to examine the potential benefits of a Personal Reminder Information and Social Management (PRISM) computer system on the well-being and perceived social support of an older adult sample at risk for social isolation. Participants (N = 300) were randomly assigned to receive the PRISM system, which was designed to support social connections, information gathering, prospective memory, and access to local and national resources, or a binder that contained similar information. The intervention lasted one year, and the computer usage of the PRISM group was monitored. This trial represented a unique opportunity to explore potential barriers to the adoption and continued use of information and communications technologies. Specifically, this paper explored the relationship between computer proficiency and use of the PRISM system over time. Contrary to what one might predict, participants with initially low proficiency used the system more over the course of the trial (r(123) = −.22, p
