title: Usability of Low-Cost Android Data Collection System for Community-Based Participatory Research.
abstract: BACKGROUND
  Android tablet computers can be valuable tools for data collection, but their usability has not been evaluated in community-based participatory research (CBPR).
  
  
  OBJECTIVE
  This article examines the usability of a low-cost bilingual touchscreen computerized survey system using Android tablets, piloted with a sample of 201 community residents in Tampa, Florida, from November 2013 to March 2014.
  
  
  METHODS
  Needs assessment questions were designed with the droidSURVEY software, and deployed using Android tablet computers. In addition, participants were asked questions about system usability.
  
  
  RESULTS
  The mean system usability was 77.57 ± 17.66 (range, 0-100). The mean completion time for taking the 63 survey questions in the needs assessment was 23.11 ± 9.62 minutes. The survey completion rate was optimal (100%), with only 6.34% missingness per variable. We found no sociodemographic differences in usability scores.
  
  
  CONCLUSIONS
  Our findings indicate that Android tablets could serve as useful tools in CBPR studies.
