The validated Research Participant Perception Survey (RPPS-Long) elicits valuable data at modest response rates.
To address this limitation, we developed shorter RPPS-Ultrashort and RPPS-Short versions, fielded them with the RPPS-Long to a random sample of a national research volunteer registry, and assessed response and completion rates, test/retest reliability, and demographics.
2228 eligible registry members received survey links. Response rates were 64% (RPPS-Ultrashort), 63% (RPPS-Short), and 51% (RPPS-Long), respectively (P<0.001). Completion rates were 63%, 54%, and 37%, respectively (p<0.001). All surveys were reliable with Cronbach's alpha = 0.81, 0.84, and 0.87, respectively. Retest reliability was highest for RPPS-Short (Kappa=0.85). Provision of compensation increased RPPS-Short completion rate from 54% to 71% (p<0.001). Compensated respondents were younger (p<0.001), with greater minority representation (p=0.03).
Shorter surveys were reliable and produced higher response and completion rates then long surveys. Compensation further increased completion rates and shifted sample age and race profiles.
经过验证的研究参与者感知调查（RPPS-长版）能以适度的回复率获取有价值的数据。
为解决这一局限性，我们开发了更短的RPPS-超短版和RPPS-短版，将它们与RPPS-长版一起应用于全国研究志愿者登记处的随机样本，并评估回复率和完成率、重测信度以及人口统计学特征。
2228名符合条件的登记成员收到了调查链接。回复率分别为64%（RPPS-超短版）、63%（RPPS-短版）和51%（RPPS-长版）（P<0.001）。完成率分别为63%、54%和37%（p<0.001）。所有调查的信度都很高，Cronbach's α分别为0.81、0.84和0.87。RPPS-短版的重测信度最高（Kappa=0.85）。提供补偿使RPPS-短版的完成率从54%提高到71%（p<0.001）。获得补偿的受访者更年轻（p<0.001），少数族裔代表性更强（p=0.03）。
较短的调查问卷信度高，且回复率和完成率高于长调查问卷。补偿进一步提高了完成率，并改变了样本的年龄和种族分布。
