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. Copyright (c) PNG Publications.
