title: Value of audio-enhanced handheld computers over paper surveys with adolescents.
abstract: OBJECTIVE
  To examine the impact of 3 data collection modes on the number of questions answered, data quality, and student preference.
  
  
  METHODS
  275 urban seventh-grade students were recruited and randomly assigned to complete a paper survey (SAQ), PDA survey (PDA), or  PDA survey with audio (APDA). Students completed a paper debriefing survey.
  
  
  RESULTS
  APDA respondents completed significantly more questions compared to SAQ and PDA. PDA and APDA had significantly less missing data than did SAQ. No differences were found for student evaluation.
  
  
  CONCLUSIONS
  Strong benefits may be gained by the use of APDA for adolescent school-based data collection.
