Sheltered in cyberspace? Computer use among the unsheltered 'street' homeless

Although physical health, mental health, and substance use problems are disproportionately high among the homeless, those with greater access to their social support systems report better outcomes than others. Communication with loved ones can be challenging for this population because of lack of access to telephone landlines. Computer technology may be an alternative medium for this population to access their social support systems, which, in turn, could lead toward better health outcomes. This exploratory study examined the computer use of 100 unsheltered homeless men and women in Philadelphia, Pennsylvania. Participants were interviewed using the Homeless Supplement to the Diagnostic Interview Schedule, a technology use module created for this investigation, and the substance use and psychiatric sections of the Addiction Severity Index. Almost half (47%) of the sample reported computer use in the past 30 days (averaging 17.67 h and 30 days). Participants used computers to maintain their sense of social connectedness, for business purposes (job and housing searches), and for leisure. Computer technology could be used to disseminate information, prevent, screen, and treat many conditions, and collect data with this difficult-to-reach population. This technology has the potential to increase access to much needed services at a relatively low cost. (C) 2010 Elsevier Ltd. All rights reserved.
