在调查研究中，父母的积极同意引起了伦理和实际问题。反对主动同意程序要求的一个常见论点是，如果对参与率有影响。还有人担心，在最后的抽样中，高风险群体的代表性可能不足。然而，缺乏对差别减员的经验支持。在当前的多中心纵向研究中，被动同意程序被批准用于收集抗议数据。对于随后几年的数据收集，需要主动父母同意程序。在这篇文章中，我们使用的预测试数据来研究人口，态度和行为的差异，为谁提供了主动同意和那些主动同意被拒绝或没有收到响应的学生。结果表明，积极的同意程序产生有害影响的参与率，并导致样本中的风险青年的代表性不足。
Active parental consent in survey research poses ethical and practical concerns. One common argument against the requirement of active consent procedures is ifs effect on participation rates. There is additional concern that higher risk groups may be underrepresented in the final sample. Empirical support of differential attrition, however is lacking. In the current multisite longitudinal study, passive consent procedures were approved for the collection of protest data For subsequent years of data collection, active parental consent procedures were required. In this article we use the pretest data to examine demographic, attitudinal, and behavioral differences between those students for whom active consent was provided and those for whom active consent was either denied or for whom no response was received. The results indicate that active consent procedures produce deleterious effects on participation rates and lead to an underrepresentation of at-risk youth in the sample.
