Does it pay to pay online panel members? A three-wave longitudinal experiment was conducted with an online panel to examine whether per person payments, paid through an online intermediary, influence response and retention rates. In the payment condition, participants were promised payment for participation at each wave, whereas control participants were not offered any payment. The promise of a payment had a negative effect on response in Wave 1, but a positive effect on response in Wave 2. Payment had no significant effect on retention. Completing a given wave was an indicator for responding to a subsequent invitation.
向在线调查小组成员付费是否值得？我们对一个在线调查小组进行了一项三阶段的纵向实验，以检验通过在线中介机构支付的每人报酬是否会影响回复率和留存率。在付费条件下，参与者被承诺在每个阶段参与调查都会获得报酬，而对照组参与者则没有得到任何报酬。报酬承诺在第一阶段对回复率有负面影响，但在第二阶段对回复率有正面影响。报酬对留存率没有显著影响。完成给定阶段是对后续邀请做出回复的一个指标。
