The Prevalence and Perceived Utility of Mobile Health Technology Among Recently Incarcerated Homeless Adults.

Mobile technologies can deliver physical and mental health services for recently incarcerated homeless adults (RIHAs). The purpose of this study was to examine the prevalence and perceived utility of mobile technology to support health behavior change among RIHAs. Participants ( = 324) from an ongoing clinical trial at a homeless shelter in Texas were included in the current descriptive cross-sectional analyses. Over one fourth (28.4%) of participants had an active cell phone. Nearly 90 percent (88.6%) of participants reported at least weekly use of the internet, 77 percent used email (77.2%), and more than half used Facebook (55.2%). Although most participants (82.8%) believed that smartphone applications (apps) could help change their behavior, only a quarter (25.1%) had used an app for this purpose. These findings highlight the potential for smartphone-based intervention technologies, and future studies should examine whether smartphone apps that address mental health and health behaviors are feasible among RIHAs.
