Area of Science:

  • Survey methodology
  • Child psychology
  • Public health research

Background:

  • Active parental consent in surveys raises ethical and practical issues.
  • Concerns exist regarding reduced participation rates and underrepresentation of high-risk groups.
  • Empirical evidence for differential attrition due to active consent is limited.

Purpose of the Study:

  • To examine demographic, attitudinal, and behavioral differences between students with and without active parental consent.
  • To assess the impact of active consent procedures on participation rates and sample representativeness.
  • To provide empirical support for concerns about differential attrition in longitudinal studies.

Main Methods:

  • A multisite longitudinal study utilizing passive consent for pretest data collection.

Related Experiment Videos

  • Transition to active parental consent procedures for subsequent data collection years.
  • Analysis of pretest data to compare students with and without active consent.

    • Main Results:

    • Active consent procedures significantly decreased participation rates.
    • Students requiring active consent were underrepresented in the sample.
    • Demographic, attitudinal, and behavioral differences were observed between consent groups, indicating potential bias.

    Conclusions:

    • Active parental consent procedures negatively affect participation rates in survey research.
    • Active consent leads to the underrepresentation of at-risk youth, compromising sample generalizability.
    • Findings highlight the need to reconsider active consent requirements in certain research contexts to ensure inclusive and representative samples.
