Comparison of web-based versus paper-and-pencil self-administered questionnaire: effects on health indicators in Dutch adolescents.

OBJECTIVE: The aim of this study is to investigate differences in responses related to (mental) health and behavior between two methods of data collection: web-based (web) and paper-and-pencil (p&p). STUDY
DESIGN: Within each participating school all third-grade classes (mainly 14-15-year-old pupils) were randomly assigned to either the Internet condition (n=271) or the paper-and-pencil condition (n=261). PRINCIPAL
FINDINGS: Significant but small differences were found for the strengths and difficulties subscales "emotional symptoms" (p&p>web) and "prosocial behavior" (p&p>web), and carrying a weapon (web>p&p). Perceived level of privacy and confidentiality did not differ between the two modes.
CONCLUSIONS: The findings suggest that in a controlled school setting, web-based administration of health indicators yields almost the same results as paper-and-pencil administration. To generalize these findings, we recommend repeated studies in other populations and settings. © Health Research and Educational Trust.
